+ 4 digit year conversion. The maximum is billions of years in the 
+future, but this is a theoretical limit as the computation of that year 
+would take too long with the current implementation of adodb_mktime().
+
+This library replaces native functions as follows:
+
+
	
+	getdate()  with  adodb_getdate()
+	date()     with  adodb_date() 
+	gmdate()   with  adodb_gmdate()
+	mktime()   with  adodb_mktime()
+	gmmktime() with  adodb_gmmktime()
+	strftime() with  adodb_strftime()
+	strftime() with  adodb_gmstrftime()
+

+	
+The parameters are identical, except that adodb_date() accepts a subset
+of date()'s field formats. Mktime() will convert from local time to GMT, 
+and date() will convert from GMT to local time, but daylight savings is 
+not handled currently.
+
+This library is independant of the rest of ADOdb, and can be used
+as standalone code.
+
+PERFORMANCE
+
+For high speed, this library uses the native date functions where
+possible, and only switches to PHP code when the dates fall outside 
+the 32-bit signed integer range.
+
+GREGORIAN CORRECTION
+
+Pope Gregory shortened October of A.D. 1582 by ten days. Thursday, 
+October 4, 1582 (Julian) was followed immediately by Friday, October 15, 
+1582 (Gregorian). 
+
+Since 0.06, we handle this correctly, so:
+
+adodb_mktime(0,0,0,10,15,1582) - adodb_mktime(0,0,0,10,4,1582) 
+	== 24 * 3600 (1 day)

+
+FUNCTION DESCRIPTIONS
+
+
+** FUNCTION adodb_getdate($date=false)
+
+Returns an array containing date information, as getdate(), but supports
+dates greater than 1901 to 2038. The local date/time format is derived from a 
+heuristic the first time adodb_getdate is called. 
+	 
+	 
+** FUNCTION adodb_date($fmt, $timestamp = false)
+
+Convert a timestamp to a formatted local date. If $timestamp is not defined, the
+current timestamp is used. Unlike the function date(), it supports dates
+outside the 1901 to 2038 range.
+
+The format fields that adodb_date supports:
+
+
+	a - "am" or "pm" 
+	A - "AM" or "PM" 
+	d - day of the month, 2 digits with leading zeros; i.e. "01" to "31" 
+	D - day of the week, textual, 3 letters; e.g. "Fri" 
+	F - month, textual, long; e.g. "January" 
+	g - hour, 12-hour format without leading zeros; i.e. "1" to "12" 
+	G - hour, 24-hour format without leading zeros; i.e. "0" to "23" 
+	h - hour, 12-hour format; i.e. "01" to "12" 
+	H - hour, 24-hour format; i.e. "00" to "23" 
+	i - minutes; i.e. "00" to "59" 
+	j - day of the month without leading zeros; i.e. "1" to "31" 
+	l (lowercase 'L') - day of the week, textual, long; e.g. "Friday"  
+	L - boolean for whether it is a leap year; i.e. "0" or "1" 
+	m - month; i.e. "01" to "12" 
+	M - month, textual, 3 letters; e.g. "Jan" 
+	n - month without leading zeros; i.e. "1" to "12" 
+	O - Difference to Greenwich time in hours; e.g. "+0200" 
+	Q - Quarter, as in 1, 2, 3, 4 
+	r - RFC 2822 formatted date; e.g. "Thu, 21 Dec 2000 16:01:07 +0200" 
+	s - seconds; i.e. "00" to "59" 
+	S - English ordinal suffix for the day of the month, 2 characters; 
+	   			i.e. "st", "nd", "rd" or "th" 
+	t - number of days in the given month; i.e. "28" to "31"
+	T - Timezone setting of this machine; e.g. "EST" or "MDT" 
+	U - seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)  
+	w - day of the week, numeric, i.e. "0" (Sunday) to "6" (Saturday) 
+	Y - year, 4 digits; e.g. "1999" 
+	y - year, 2 digits; e.g. "99" 
+	z - day of the year; i.e. "0" to "365" 
+	Z - timezone offset in seconds (i.e. "-43200" to "43200"). 
+	   			The offset for timezones west of UTC is always negative, 
+				and for those east of UTC is always positive. 
+

+
+Unsupported:
+
+	B - Swatch Internet time 
+	I (capital i) - "1" if Daylight Savings Time, "0" otherwise.
+	W - ISO-8601 week number of year, weeks starting on Monday 
+
+

+
+
+** FUNCTION adodb_date2($fmt, $isoDateString = false)
+Same as adodb_date, but 2nd parameter accepts iso date, eg.
+
+  adodb_date2('d-M-Y H:i','2003-12-25 13:01:34');
+
+  
+** FUNCTION adodb_gmdate($fmt, $timestamp = false)
+
+Convert a timestamp to a formatted GMT date. If $timestamp is not defined, the
+current timestamp is used. Unlike the function date(), it supports dates
+outside the 1901 to 2038 range.
+
+
+** FUNCTION adodb_mktime($hr, $min, $sec[, $month, $day, $year])
+
+Converts a local date to a unix timestamp.  Unlike the function mktime(), it supports
+dates outside the 1901 to 2038 range. All parameters are optional.
+
+
+** FUNCTION adodb_gmmktime($hr, $min, $sec [, $month, $day, $year])
+
+Converts a gmt date to a unix timestamp.  Unlike the function gmmktime(), it supports
+dates outside the 1901 to 2038 range. Differs from gmmktime() in that all parameters
+are currently compulsory.
+
+** FUNCTION adodb_gmstrftime($fmt, $timestamp = false)
+Convert a timestamp to a formatted GMT date.
+
+** FUNCTION adodb_strftime($fmt, $timestamp = false)
+
+Convert a timestamp to a formatted local date. Internally converts $fmt into 
+adodb_date format, then echo result.
+
+For best results, you can define the local date format yourself. Define a global
+variable $ADODB_DATE_LOCALE which is an array, 1st element is date format using
+adodb_date syntax, and 2nd element is the time format, also in adodb_date syntax.
+
+    eg. $ADODB_DATE_LOCALE = array('d/m/Y','H:i:s');
+	
+	Supported format codes:
+
+
+	%a - abbreviated weekday name according to the current locale 
+	%A - full weekday name according to the current locale 
+	%b - abbreviated month name according to the current locale 
+	%B - full month name according to the current locale 
+	%c - preferred date and time representation for the current locale 
+	%d - day of the month as a decimal number (range 01 to 31) 
+	%D - same as %m/%d/%y 
+	%e - day of the month as a decimal number, a single digit is preceded by a space (range ' 1' to '31') 
+	%h - same as %b
+	%H - hour as a decimal number using a 24-hour clock (range 00 to 23) 
+	%I - hour as a decimal number using a 12-hour clock (range 01 to 12) 
+	%m - month as a decimal number (range 01 to 12) 
+	%M - minute as a decimal number 
+	%n - newline character 
+	%p - either `am' or `pm' according to the given time value, or the corresponding strings for the current locale 
+	%r - time in a.m. and p.m. notation 
+	%R - time in 24 hour notation 
+	%S - second as a decimal number 
+	%t - tab character 
+	%T - current time, equal to %H:%M:%S 
+	%x - preferred date representation for the current locale without the time 
+	%X - preferred time representation for the current locale without the date 
+	%y - year as a decimal number without a century (range 00 to 99) 
+	%Y - year as a decimal number including the century 
+	%Z - time zone or name or abbreviation 
+	%% - a literal `%' character 
+
	
+
+	Unsupported codes:
+
+	%C - century number (the year divided by 100 and truncated to an integer, range 00 to 99) 
+	%g - like %G, but without the century. 
+	%G - The 4-digit year corresponding to the ISO week number (see %V). 
+	     This has the same format and value as %Y, except that if the ISO week number belongs 
+		 to the previous or next year, that year is used instead. 
+	%j - day of the year as a decimal number (range 001 to 366) 
+	%u - weekday as a decimal number [1,7], with 1 representing Monday 
+	%U - week number of the current year as a decimal number, starting 
+	    with the first Sunday as the first day of the first week 
+	%V - The ISO 8601:1988 week number of the current year as a decimal number, 
+	     range 01 to 53, where week 1 is the first week that has at least 4 days in the 
+		 current year, and with Monday as the first day of the week. (Use %G or %g for 
+		 the year component that corresponds to the week number for the specified timestamp.) 
+	%w - day of the week as a decimal, Sunday being 0 
+	%W - week number of the current year as a decimal number, starting with the 
+	     first Monday as the first day of the first week 
+

+NOTES
+
+Useful url for generating test timestamps:
+	http://www.4webhelp.net/us/timestamp.php
+
+Possible future optimizations include 
+
+a. Using an algorithm similar to Plauger's in "The Standard C Library" 
+(page 428, xttotm.c _Ttotm() function). Plauger's algorithm will not 
+work outside 32-bit signed range, so i decided not to implement it.
+
+b. Implement daylight savings, which looks awfully complicated, see

+
+CHANGELOG
+
+- 11 Feb 2008 0.33
+* Bug in 0.32 fix for hour handling. Fixed.
+
+- 1 Feb 2008 0.32
+* Now adodb_mktime(0,0,0,12+$m,20,2040) works properly. 
+
+- 10 Jan 2008 0.31
+* Now adodb_mktime(0,0,0,24,1,2037) works correctly.
+
+- 15 July 2007 0.30
+Added PHP 5.2.0 compatability fixes. 
+ * gmtime behaviour for 1970 has changed. We use the actual date if it is between 1970 to 2038 to get the
+ * timezone, otherwise we use the current year as the baseline to retrieve the timezone.
+ * Also the timezone's in php 5.2.* support historical data better, eg. if timezone today was +8, but 
+   in 1970 it was +7:30, then php 5.2 return +7:30, while this library will use +8.
+ * 
+ 
+- 19 March 2006 0.24
+Changed strftime() locale detection, because some locales prepend the day of week to the date when %c is used.
+
+- 10 Feb 2006 0.23
+PHP5 compat: when we detect PHP5, the RFC2822 format for gmt 0000hrs is changed from -0000 to +0000. 
+	In PHP4, we will still use -0000 for 100% compat with PHP4.
+
+- 08 Sept 2005 0.22
+In adodb_date2(), $is_gmt not supported properly. Fixed.
+
+- 18 July  2005 0.21
+In PHP 4.3.11, the 'r' format has changed. Leading 0 in day is added. Changed for compat.
+Added support for negative months in adodb_mktime().
+
+- 24 Feb 2005 0.20
+Added limited strftime/gmstrftime support. x10 improvement in performance of adodb_date().
+
+- 21 Dec 2004 0.17
+In adodb_getdate(), the timestamp was accidentally converted to gmt when $is_gmt is false. 
+Also adodb_mktime(0,0,0) did not work properly. Both fixed thx Mauro.
+
+- 17 Nov 2004 0.16
+Removed intval typecast in adodb_mktime() for secs, allowing:
+	 adodb_mktime(0,0,0 + 2236672153,1,1,1934);
+Suggested by Ryan.
+
+- 18 July 2004 0.15
+All params in adodb_mktime were formerly compulsory. Now only the hour, min, secs is compulsory. 
+This brings it more in line with mktime (still not identical).
+
+- 23 June 2004 0.14
+
+Allow you to define your own daylights savings function, adodb_daylight_sv.
+If the function is defined (somewhere in an include), then you can correct for daylights savings.
+
+In this example, we apply daylights savings in June or July, adding one hour. This is extremely
+unrealistic as it does not take into account time-zone, geographic location, current year.
+
+function adodb_daylight_sv(&$arr, $is_gmt)
+{
+	if ($is_gmt) return;
+	$m = $arr['mon'];
+	if ($m == 6 || $m == 7) $arr['hours'] += 1;
+}
+
+This is only called by adodb_date() and not by adodb_mktime(). 
+
+The format of $arr is
+Array ( 
+   [seconds] => 0 
+   [minutes] => 0 
+   [hours] => 0 
+   [mday] => 1      # day of month, eg 1st day of the month
+   [mon] => 2       # month (eg. Feb)
+   [year] => 2102 
+   [yday] => 31     # days in current year
+   [leap] =>        # true if leap year
+   [ndays] => 28    # no of days in current month
+   ) 
+   
+
+- 28 Apr 2004 0.13
+Fixed adodb_date to properly support $is_gmt. Thx to Dimitar Angelov.
+
+- 20 Mar 2004 0.12
+Fixed month calculation error in adodb_date. 2102-June-01 appeared as 2102-May-32.
+
+- 26 Oct 2003 0.11
+Because of daylight savings problems (some systems apply daylight savings to 
+January!!!), changed adodb_get_gmt_diff() to ignore daylight savings.
+
+- 9 Aug 2003 0.10
+Fixed bug with dates after 2038. 
+See http://phplens.com/lens/lensforum/msgs.php?id=6980
+
+- 1 July 2003 0.09
+Added support for Q (Quarter).
+Added adodb_date2(), which accepts ISO date in 2nd param
+
+- 3 March 2003 0.08
+Added support for 'S' adodb_date() format char. Added constant ADODB_ALLOW_NEGATIVE_TS
+if you want PHP to handle negative timestamps between 1901 to 1969.
+
+- 27 Feb 2003 0.07
+All negative numbers handled by adodb now because of RH 7.3+ problems.
+See http://bugs.php.net/bug.php?id=20048&edit=2
+
+- 4 Feb 2003 0.06
+Fixed a typo, 1852 changed to 1582! This means that pre-1852 dates
+are now correctly handled.
+
+- 29 Jan 2003 0.05
+
+Leap year checking differs under Julian calendar (pre 1582). Also
+leap year code optimized by checking for most common case first.
+
+We also handle month overflow correctly in mktime (eg month set to 13).
+
+Day overflow for less than one month's days is supported.
+
+- 28 Jan 2003 0.04
+
+Gregorian correction handled. In PHP5, we might throw an error if 
+mktime uses invalid dates around 5-14 Oct 1582. Released with ADOdb 3.10.
+Added limbo 5-14 Oct 1582 check, when we set to 15 Oct 1582.
+
+- 27 Jan 2003 0.03
+
+Fixed some more month problems due to gmt issues. Added constant ADODB_DATE_VERSION.
+Fixed calculation of days since start of year for <1970. 
+
+- 27 Jan 2003 0.02
+
+Changed _adodb_getdate() to inline leap year checking for better performance.
+Fixed problem with time-zones west of GMT +0000.
+
+- 24 Jan 2003 0.01
+
+First implementation.

ADOdb Active Record

+
    
+
+
  1. Introduction
    2. 
+
    
+ADOdb_Active_Record is an Object Relation Mapping (ORM) implementation using PHP. In an ORM system, the tables and rows of the database are abstracted into native PHP objects. This allows the programmer to focus more on manipulating the data and less on writing SQL queries.
+
    
+This implementation differs from Zend Framework's implementation in the following ways:
+
      
+
    • Works with PHP4 and PHP5 and provides equivalent functionality in both versions of PHP.
      
+
    • ADOdb_Active_Record works when you are connected to multiple databases. Zend's only works when connected to a default database.
      
+
    • Support for $ADODB_ASSOC_CASE. The field names are upper-cased, lower-cased or left in natural case depending on this setting.
      
+
    • No field name conversion to camel-caps style, unlike Zend's implementation which will convert field names such as 'first_name' to 'firstName'.
      
+
    • NewADOConnection::GetActiveRecords() and ADOConnection::GetActiveRecordsClass() functions in adodb.inc.php.
      
+
    • Caching of table metadata so it is only queried once per table, no matter how many Active Records are created.
      
+
    • PHP5 version of ADOdb_Active_Record now supports one-to-many relationships.
      
+
    • New adodb-active-recordx.inc.php, which is an Active Record eXtended implementation that support JOINs for higher performance when loading children, and other nice features.
      
+
    • Lots of  additional functionality.
       
+
    
+
    
+ADOdb_Active_Record is designed upon the principles of the "ActiveRecord" design pattern, which was first described by Martin Fowler. The ActiveRecord pattern has been implemented in many forms across the spectrum of programming languages. ADOdb_Active_Record attempts to represent the database as closely to native PHP objects as possible.
+
    
+ADOdb_Active_Record maps a database table to a PHP class, and each instance of that class represents a table row. Relations between tables can also be defined, allowing the ADOdb_Active_Record objects to be nested.
+
    
+
+
  2. Setting the Database Connection
    3. 
+
    
+The first step to using  ADOdb_Active_Record is to set the default connection that an ADOdb_Active_Record objects will use to connect to a database. 
+
+
    +require_once('adodb/adodb-active-record.inc.php');
+
+$db = NewADOConnection('mysql://root:pwd@localhost/dbname');
+ADOdb_Active_Record::SetDatabaseAdapter($db);
+
            
+
+
  3. Table Rows as Objects
    4. 
+
    
+First, let's create a temporary table in our MySQL database that we can use for demonstrative purposes throughout the rest of this tutorial. We can do this by sending a CREATE query:
+
+
    +$db->Execute("CREATE TEMPORARY TABLE `persons` (
+                `id` int(10) unsigned NOT NULL auto_increment,
+                `name_first` varchar(100) NOT NULL default '',
+                `name_last` varchar(100) NOT NULL default '',
+                `favorite_color` varchar(100) NOT NULL default '',
+                PRIMARY KEY  (`id`)
+            ) ENGINE=MyISAM;
+           ");
+ 
       
+
    
+ADOdb_Active_Records are object representations of table rows. Each table in the database is represented by a class in PHP. To begin working with a table as a ADOdb_Active_Record, a class that extends ADOdb_Active_Record needs to be created for it.
+
+
    +class person extends ADOdb_Active_Record{}
+$person = new person();
+
       
+
+
    
+In the above example, a new ADOdb_Active_Record object $person was created to access the "persons" table. Zend_Db_DataObject takes the name of the class, pluralizes it (according to American English rules), and assumes that this is the name of the table in the database. Also note that with MySQL, table names are case-sensitive, so your class name must match the table name's case. With other databases with case-insensitive tables, your class can be capitalized differently.
+
    
+This kind of behavior is typical of ADOdb_Active_Record. It will assume as much as possible by convention rather than explicit configuration. In situations where it isn't possible to use the conventions that ADOdb_Active_Record expects, options can be overridden as we'll see later.
+
+
  4. Table Columns as Object Properties
    5. 
+
    
+When the $person object was instantiated, ADOdb_Active_Record read the table metadata from the database itself, and then exposed the table's columns (fields) as object properties.
+
    
+Our "persons" table has three fields: "name_first", "name_last", and "favorite_color". Each of these fields is now a property of the $person object. To see all these properties, use the ADOdb_Active_Record::getAttributeNames() method:
+
    +var_dump($person->getAttributeNames());
+
+/**
+ * Outputs the following:
+ * array(4) {
+ *    [0]=>
+ *    string(2) "id"
+ *    [1]=>
+ *    string(9) "name_first"
+ *    [2]=>
+ *    string(8) "name_last"
+ *    [3]=>
+ *    string(13) "favorite_color"
+ *  }
+ */
+    
       
+
    
+One big difference between ADOdb and Zend's implementation is we do not automatically convert to camelCaps style.
+
    
+
  5. Inserting and Updating a Record
    6. 
+
+An ADOdb_Active_Record object is a representation of a single table row. However, when our $person object is instantiated, it does not reference any particular row. It is a blank record that does not yet exist in the database. An ADOdb_Active_Record object is considered blank when its primary key is NULL. The primary key in our persons table is "id".
+
    
+To insert a new record into the database, change the object's properties and then call the ADOdb_Active_Record::save() method:
+
    +$person = new person();
+$person->name_first = 'Andi';
+$person->name_last  = 'Gutmans';
+$person->save();
+ 
       
+
    
+Oh, no! The above code snippet does not insert a new record into the database. Instead, outputs an error:
+
    +1048: Column 'favorite_color' cannot be null
+ 
       
+
    
+This error occurred because MySQL rejected the INSERT query that was generated by ADOdb_Active_Record. If exceptions are enabled in ADOdb and you are using PHP5, an error will be thrown. In the definition of our table, we specified all of the fields as NOT NULL; i.e., they must contain a value.
+
    
+ADOdb_Active_Records are bound by the same contraints as the database tables they represent. If the field in the database cannot be NULL, the corresponding property in the ADOdb_Active_Record also cannot be NULL. In the example above, we failed to set the property $person->favoriteColor, which caused the INSERT to be rejected by MySQL.
+
    
+To insert a new ADOdb_Active_Record in the database, populate all of ADOdb_Active_Record's properties so that they satisfy the constraints of the database table, and then call the save() method:
+
    +/**
+ * Calling the save() method will successfully INSERT
+ * this $person into the database table.
+ */
+$person = new person();
+$person->name_first     = 'Andi';
+$person->name_last      = 'Gutmans';
+$person->favorite_color = 'blue';
+$person->save();
+
    
+
    
+Once this $person has been INSERTed into the database by calling save(), the primary key can now be read as a property. Since this is the first row inserted into our temporary table, its "id" will be 1:
+
    +var_dump($person->id);
+
+/**
+ * Outputs the following:
+ * string(1)
+ */
+ 
           
+
    
+From this point on, updating it is simply a matter of changing the object's properties and calling the save() method again:
+
+
    +$person->favorite_color = 'red';
+$person->save();
+   
    
+
    
+The code snippet above will change the favorite color to red, and then UPDATE the record in the database.
+
+
+
    ADOdb Specific Functionality
    
+
  6. Setting the Table Name
    7. 
+
    The default behaviour on creating an ADOdb_Active_Record is to "pluralize" the class name and
+ use that as the table name. Often, this is not the case. For example, the person class could be reading 
+ from the "People" table. 
+
    We provide two ways to define your own table:
+
    1. Use a constructor parameter to override the default table naming behaviour.
+
    +	class person extends ADOdb_Active_Record{}
+	$person = new person('People');
+
    
+
    2. Define it in a class declaration:
+
    +	class person extends ADOdb_Active_Record
+	{
+	var $_table = 'People';
+	}
+	$person = new person();
+
    
+
+
  7. $ADODB_ASSOC_CASE
    8. 
+
    This allows you to control the case of field names and properties. For example, all field names in Oracle are upper-case by default. So you 
+can force field names to be lowercase using $ADODB_ASSOC_CASE. Legal values are as follows:
+
    + 0: lower-case
+ 1: upper-case
+ 2: native-case
+
    
+
    So to force all Oracle field names to lower-case, use
+
    +$ADODB_ASSOC_CASE = 0;
+$person = new person('People');
+$person->name = 'Lily';
+$ADODB_ASSOC_CASE = 2;
+$person2 = new person('People');
+$person2->NAME = 'Lily'; 
+
    
+
+
    Also see $ADODB_ASSOC_CASE.
+
+
  8. ADOdb_Active_Record::Save()
    9. 
+
    
+Saves a record by executing an INSERT or UPDATE SQL statement as appropriate. 
+
    Returns false on  unsuccessful INSERT, true if successsful INSERT.
+
    Returns 0 on failed UPDATE, and 1 on UPDATE if data has changed, and -1 if no data was changed, so no UPDATE statement was executed.
+
+
  9. ADOdb_Active_Record::Replace()
    10. 
+
    
+ADOdb supports replace functionality, whereby the record is inserted if it does not exists, or updated otherwise.
+
    +$rec = new ADOdb_Active_Record("product");
+$rec->name = 'John';
+$rec->tel_no = '34111145';
+$ok = $rec->replace(); // 0=failure, 1=update, 2=insert
+
    
+
+
+
  10. ADOdb_Active_Record::Load($where)
    11. 
+
    Sometimes, we want to load a single record into an Active Record. We can do so using:
+
    +$person->load("id=3");
+
+// or using bind parameters
+
+$person->load("id=?", array(3));
+
    
+
    Returns false if an error occurs.
+
+
  11. ADOdb_Active_Record::Find($whereOrderBy, $bindarr=false, $pkeyArr=false)
    12. 
+
    We want to retrieve an array of active records based on some search criteria. For example:
+
    +class person extends ADOdb_Active_Record {
+var $_table = 'people';
+}
+
+$person = new person();
+$peopleArray = $person->Find("name like ? order by age", array('Sm%'));
+
    
+
+
  12. Quoting Identifiers
    13. 
+
    You can force column names to be quoted in INSERT and UPDATE statements, typically because you are using reserved words as column names by setting
+
    +ADODB_Active_Record::$_quoteNames = true;
+
    
+
    Default is false.
+
+
  13. Error Handling and Debugging
    14. 
+
    
+In PHP5, if adodb-exceptions.inc.php is included, then errors are thrown. Otherwise errors are handled by returning a value. False by default means an error has occurred. You can get the last error message using the ErrorMsg() function. 
+
    
+To check for errors in ADOdb_Active_Record, do not poll ErrorMsg() as the last error message will always be returned, even if it occurred several operations ago. Do this instead:
+
    +# right!
+$ok = $rec->Save();
+if (!$ok) $err = $rec->ErrorMsg();
+
+# wrong :(
+$rec->Save();
+if ($rec->ErrorMsg()) echo "Wrong way to detect error";
+
    
+
    The ADOConnection::Debug property is obeyed. So
+if $db->debug is enabled, then ADOdb_Active_Record errors are also outputted to standard output and written to the browser.
+
+
  14. ADOdb_Active_Record::Set()
    15. 
+
    You can convert an array to an ADOdb_Active_Record using Set(). The array must be numerically indexed, and have all fields of the table defined in the array. The elements of the array must be in the table's natural order too.
+
    +$row = $db->GetRow("select * from tablex where id=$id");
+
+# PHP4 or PHP5 without enabling exceptions
+$obj = new ADOdb_Active_Record('Products');
+if ($obj->ErrorMsg()){
+	echo $obj->ErrorMsg();
+} else {
+	$obj->Set($row);
+}
+
+# in PHP5, with exceptions enabled:
+
+include('adodb-exceptions.inc.php');
+try {
+	$obj = new ADOdb_Active_Record('Products');
+	$obj->Set($row);
+} catch(exceptions $e) {
+	echo $e->getMessage();
+}
+
    
+
    
+
  15. Primary Keys
    16. 
+
    
+ADOdb_Active_Record does not require the table to have a primary key. You can insert records for such a table, but you will not be able to update nor delete. 
+
    Sometimes you are retrieving data from a view or table that has no primary key, but has a unique index. You can dynamically set the primary key of a table through the constructor:
+
    +	$pkeys = array('category','prodcode');
+	
+	// set primary key using constructor
+	$rec = new ADOdb_Active_Record('Products', $pkeys);
+	
+	// or define a new class
+	class Product extends ADOdb_Active_Record {
+		function __construct()
+		{
+			parent::__construct('Products', array('prodid'));
+		}
+	}
+	
+	$rec = new Product();
+
    
+
+
+
  16. Retrieval of Auto-incrementing ID
    17. 
+When creating a new record, the retrieval of the last auto-incrementing ID is not reliable for databases that do not support the Insert_ID() function call (check $connection->hasInsertID). In this case we perform a SELECT MAX($primarykey) FROM $table, which will not work reliably in a multi-user environment. You can override the ADOdb_Active_Record::LastInsertID() function in this case.
+
+
  17. Dealing with Multiple Databases
    18. 
+
    
+Sometimes we want to load data from one database and insert it into another using ActiveRecords. This can be done using the optional parameter of the ADOdb_Active_Record constructor. In the following example, we read data from db.table1 and store it in db2.table2:
+
    +$db = NewADOConnection(...);
+$db2 = NewADOConnection(...);
+
+ADOdb_Active_Record::SetDatabaseAdapter($db2);
+
+$activeRecs = $db->GetActiveRecords('table1');
+
+foreach($activeRecs as $rec) {
+	$rec2 = new ADOdb_Active_Record('table2',$db2);
+	$rec2->id = $rec->id;
+	$rec2->name = $rec->name;
+	
+	$rec2->Save();
+}
+
    
+
    
+If you have to pass in a primary key called "id" and the 2nd db connection in the constructor, you can do so too:
+
    +$rec = new ADOdb_Active_Record("table1",array("id"),$db2);
+
    
+
    You can now give a named label in SetDatabaseAdapter, allowing to determine in your class definition which database to load, using var $_dbat.
+
    +$db1 = NewADOConnection(...); // some ADOdb DB
+ADOdb_Active_Record::SetDatabaseAdapter($db1, 'mysql');
+$db2 = NewADOConnection(...); // some ADOdb DB
+ADOdb_Active_Record::SetDatabaseAdapter($db2, 'oracle');
+
+class FooRecord extends ADOdb_Active_Record
+{
+var $_dbat = 'mysql';  // uses 'mysql' connection
+...
+}
+
    
+
  18. $ADODB_ACTIVE_CACHESECS
    19. 
+
    You can cache the table metadata (field names, types, and other info such primary keys) in $ADODB_CACHE_DIR (which defaults to /tmp) by setting
+the global variable $ADODB_ACTIVE_CACHESECS to a value greater than 0. This will be the number of seconds to cache.
+ You should set this to a value of 30 seconds or greater for optimal performance.
+
+
  19. Active Record Considered Bad?
    20. 
+
    Although the Active Record concept is useful, you have to be aware of some pitfalls when using Active Record. The level of granularity of Active Record is individual records. It encourages code like the following, used to increase the price of all furniture products by 10%:
+
    + $recs = $db->GetActiveRecords("Products","category='Furniture'");
+ foreach($recs as $rec) {
+    $rec->price *= 1.1; // increase price by 10% for all Furniture products
+    $rec->save();
+ }
+
    
+Of course an UPDATE statement is superior because it's simpler and much more efficient (probably by a factor of x10 or more):
+
    +   $db->Execute("update Products set price = price * 1.1 where category='Furniture'");
+
    
+
    For performance sensitive code, using direct SQL will always be faster than using Active Records due to overhead and the fact that all fields in a row are retrieved (rather than only the subset you need) whenever an Active Record is loaded.
+
+
  20. Transactions
    21. 
+
    
+The default transaction mode in ADOdb is autocommit. So that is the default with active record too. 
+The general rules for managing transactions still apply. Active Record to the database is a set of insert/update/delete statements, and the db has no knowledge of active records.
+
    
+Smart transactions, that does an auto-rollback if an error occurs, is still the best method to multiple activities (inserts/updates/deletes) that need to be treated as a single transaction:
+
    +$conn->StartTrans();
+$parent->save();
+$child->save();
+$conn->CompleteTrans();
+
    
+
+
+
    One to Many Relations
    
+
    Since ADOdb 5.06, we support parent child relationships. This is done using the ClassBelongsTo() and ClassHasMany() functions. 
+
+
  21. ClassHasMany
    22. 
+
    To globally define a one-to-many relationship we use the static function ADODB_Active_Record::ClassHasMany($class, $relation, $foreignKey = '', $foreignClass = 'ADODB_Active_Record'). For example, we have 2 tables, persons (parent table) and children (child table)
+linked by persons.id = children.person_id. The variable $person->children is an array that holds the children. To define this relationship:
+
    +	class person extends ADOdb_Active_Record{}
+	ADODB_Active_Record::ClassHasMany('person', 'children','person_id');
+	
+	$person = new person();
+	$person->Load("id=1");
+	foreach($person->children as $c) {
+		echo " $c->name_first ";
+		$c->name_first .= ' K.';
+		$c->Save();  ## each child record must be saved individually
+	}
+
    
+
    If no data is loaded, then children is set to an empty array:
+
    +	$person2 = new person();
+	$p = $person2->children;  ## $p is an empty array()
+
    
+
    By default, data returned by HasMany() is unsorted. To define an order by clause (or define a SELECT LIMIT window), see LoadRelations() below. Another point is that all children are loaded only when the child member is accessed (in __get), and not when the Load() function of the parent object is called. This helps to conserve memory.
+
+
    To create and save new parent and child records:
+
    +
+	class person extends ADOdb_Active_Record{}
+	class children extends ADOdb_Active_Record{}
+	ADODB_Active_Record::ClassHasMany('person', 'children','person_id');
+	
+	$person = new person();
+	
+	for ($i=0; $i<10; $i++) 
+		$person->children[0] = new children('children');
+	 
+	 // modify fields of $person, then...
+	$person->save();
+	
+	foreach($person->children as $c) {
+		// modify fields of $c then...
+		$c->save();
+	}
+
    
+
    You can have multiple relationships (warning: relations are case-sensitive, 'Children' !== 'children'):
+
    +	ADODB_Active_Record::ClassHasMany('person', 'children','person_id');
+	ADODB_Active_Record::ClassHasMany('person', 'siblings','person_id');
+	$person = new person();
+	$person->Load('id=1');
+	var_dump($person->children);
+	var_dump($person->siblings);
+
    
+
    By default, the child class is ADOdb_Active_Record. Sometimes you might want the child class to be based on your own class which has additional functions. You can do so using the last parameter:
+
    +	class person extends ADOdb_Active_Record{}
+	class child extends ADOdb_Active_Record { .... some modifications here ... }
+	ADODB_Active_Record::ClassHasMany('person', 'children','person_id', 'child');
+
    
+
    Lastly some troubleshooting issues. We use the __get() method to set 
+$p->children below. So once $p->children is defined by accessing it, we don't change the child reference, as shown below:
+
    +	ADODB_Active_Record::ClassHasMany('person', 'children','person_id');
+	$p = new person();
+	$p->Load('id=1');
+	# $p->children points to person_id = 1
+	var_dump($p->children);
+	
+	$p->Load('id=2');
+	# $p->children still points to person_id = 1
+	var_dump($p->children); 
+
    
+
    The solution to the above is to unset($p->children) before $p->Load('id=2').
+
  22. TableHasMany
    23. 
+For some classes, the mapping between class name and table name (which is the pluralised version) might not match. For example, 
+the class name might be person, but the table name might be people. So we have 2 tables, people (parent table) and children (child table)
+linked by people.id = children.person_id.
+
    Then you use the following static function
+ ADODB_Active_Record::TableHasMany($table, $relation, $foreignKey = '', $foreignClass = 'ADODB_Active_Record') like this:
+
    +ADODB_Active_Record::TableHasMany('people', 'children', 'person_id')
+
    
+
  23. TableKeyHasMany
    24. 
+For some classes, the mapping between class name and table name (which is the pluralised version) might not match or the primary key is not the default id. For example, 
+the class name might be person, but the table name might be people. So we have 2 tables, people (parent table) and children (child table)
+linked by people.pid = children.person_id.
+
    Then you use the following static function
+ ADODB_Active_Record::TableKeyHasMany($table, $tablePKey, $relation, $foreignKey = '', $foreignClass = 'ADODB_Active_Record') like this:
+
    +ADODB_Active_Record::TableKeyHasMany('people', 'pid', 'children', 'person_id')
+
    
+
+
+
  24. A Complete ClassHasMany example
    25. 
+
    Here is sample usage using mysql:
+
    +	include_once('../adodb.inc.php');
+	include_once('../adodb-active-record.inc.php');
+
+	$db = NewADOConnection('mysql://root@localhost/northwind');
+	ADOdb_Active_Record::SetDatabaseAdapter($db);
+
+	$db->Execute("CREATE TEMPORARY TABLE `persons` (
+	                `id` int(10) unsigned NOT NULL auto_increment,
+	                `name_first` varchar(100) NOT NULL default '',
+	                `name_last` varchar(100) NOT NULL default '',
+	                `favorite_color` varchar(100) NOT NULL default '',
+	                PRIMARY KEY  (`id`)
+	            ) ENGINE=MyISAM;
+	           ");
+			   
+	$db->Execute("CREATE TEMPORARY TABLE `children` (
+	                `id` int(10) unsigned NOT NULL auto_increment,
+					`person_id` int(10) unsigned NOT NULL,
+					`gender` varchar(10) default 'F',
+	                `name_first` varchar(100) NOT NULL default '',
+	                `name_last` varchar(100) NOT NULL default '',
+	                `favorite_pet` varchar(100) NOT NULL default '',
+	                PRIMARY KEY  (`id`)
+	            ) ENGINE=MyISAM;
+	           ");
+			   
+	$db->Execute("insert into children (person_id,name_first,name_last) values (1,'Jill','Lim')");
+	$db->Execute("insert into children (person_id,name_first,name_last) values (1,'Joan','Lim')");
+	$db->Execute("insert into children (person_id,name_first,name_last) values (1,'JAMIE','Lim')");
+			   
+	class person extends ADOdb_Active_Record{}
+	ADODB_Active_Record::ClassHasMany('person', 'children','person_id');	
+	
+	$person = new person();
+	
+	$person->name_first     = 'John';
+	$person->name_last      = 'Lim';
+	$person->favorite_color = 'lavender';
+	$person->save(); // this save will perform an INSERT successfully
+	
+	$person2 = new person(); # no need to define HasMany() again, adodb remembers definition
+	$person2->Load('id=1');
+	
+	$c = $person2->children;
+	if (is_array($c) && sizeof($c) == 3 && $c[0]->name_first=='Jill' && $c[1]->name_first=='Joan'
+		&& $c[2]->name_first == 'JAMIE') echo "OK Loaded HasMany<br>";
+	else {
+		echo "Error loading hasMany should have 3 array elements Jill Joan Jamie<br>";
+	}
+
    
+
+
  25. HasMany
    26. 
+
    This older method is deprecated and ClassHasMany/TableHasMany/TableKeyHasMany should be used. 
+
    The older way to define a one-to-many relationship is to use $parentobj->HasMany($relation, $foreignKey = ''). For example, we have 2 tables, persons (parent table) and children (child table)
+linked by persons.id = children.person_id. The variable $person->children is an array that holds the children. To define this relationship:
+
    +	class person extends ADOdb_Active_Record{}
+	
+	$person = new person();
+	$person->HasMany('children','person_id');
+	$person->Load("id=1");
+	foreach($person->children as $c) {
+		echo " $c->name_first ";
+		$c->name_first .= ' K.';
+		$c->Save();  ## each child record must be saved individually
+	}
+
    
+
    This HasMany() definition is global for the current script. This means that you only need to define it once. In the following example, $person2 knows about children.
+
    +	$person = new person();
+	$person->HasMany('children','person_id');
+	
+	$person2 = new person();
+	$person->Load("id=1");
+	$p = $person2->children;
+
    
+
+
+
  26. ClassBelongsTo
    27. 
+
    You can define the parent of the current object using ADODB_Active_Record::ClassBelongsTo($class, $relationName, $foreignKey, $parentPrimaryKey = 'id', $parentClass = 'ADODB_Active_Record'). In the example below,
+we have a child table kids, and a parent table person. We have a link kids.person_id = persons.id. We create a child first, then link it to the parent:
+
    +	class kid extends ADOdb_Active_Record{};
+	ADODB_Active_Record::ClassBelongsTo('kid','person','person_id','id'); 
+
+	$ch = new kid(); // default tablename will be 'kids', with primary key 'id' 
+	$ch->Load('id=1');
+	$p = $ch->person;
+	if (!$p || $p->name_first != 'John') echo "Error loading belongsTo<br>";
+	else echo "OK loading BelongTo<br>";
+
    
+
    
+
    Note that relationships are case-sensitive, so ClassBelongsTo('kid','PARENT', 'parent_id') and ClassBelongsTo('kid', 'parent', 'parent_id') are not the same. 
+
    Also if no data is loaded into the child instance, then $p will return null;
+
    +	ADODB_Active_Record::ClassBelongsTo('kid','person','person_id','id'); 
+	
+	$ch = new kid();
+	$p = $ch->person; # $p is null
+
    
+
    Another way to define the class of the parent (which otherwise defaults to ADODB_Active_Record) as follows:
+
    +
+	class kid extends ADOdb_Active_Record{};
+	class person extends ADOdb_Active_Record{... your modifications ... };
+	ADODB_Active_Record::ClassBelongsTo('kid','person','person_id','id', 'person'); 
+
    
+
  27. TableBelongsTo
    28. 
+
    If the child table differs from the convention that the child table name is the plural of the child class name, use this function:
+ADODB_Active_Record::TableBelongsTo($childTable, $relationName, $foreignKey, $parentPrimaryKey = 'id', $parentClass = 'ADODB_Active_Record').
+
    E.g. the class is child, but the table name is children, and the link between the two tables is children.person_id = person.id:
+
    +	ADODB_Active_Record::TableBelongsTo('children','person','person_id','id');
+
    
+
  28. TableKeyBelongsTo
    29. 
+
    If the child table differs from the convention that the child table name is the plural of the child class name or the primary key is not 'id', use this function:
+ADODB_Active_Record::TableKeyBelongsTo($childTable, $childKey, $relationName, $foreignKey, $parentPrimaryKey = 'id', $parentClass = 'ADODB_Active_Record').
+
    E.g. the class is child, but the table name is children and primary key is ch_id, and the link between the two tables is children.person_id = person.id:
+
    +	ADODB_Active_Record::TableKeyBelongsTo('children','ch_id', 'person','person_id','id');
+
    
+
  29. BelongsTo
    30. 
+
    The following is deprecated. Use ClassBelongsTo/TableBelongsTo/TableKeyBelongsTo instead.
+
    The older way to define the parent of the current object is using BelongsTo($relationName, $foreignKey, $parentPrimaryKey = 'id'). In the example below,
+we have a child table children, and a parent table person. We have a link children.person_id = persons.id. We create a child first, then link it to the parent:
+
    +	class Child extends ADOdb_Active_Record{};
+	$ch = new Child('children',array('id'));
+	$ch->BelongsTo('person','person_id','id');  ## this can be simplified to $ch->BelongsTo('person')
+	                                            ## as foreign key defaults to $table.'_id' and 
+	                                            ## parent pkey defaults to 'id' 
+	$ch->Load('id=1');
+	$p = $ch->person;
+	if (!$p || $p->name_first != 'John') echo "Error loading belongsTo<br>";
+	else echo "OK loading BelongTo<br>";
+
    
+
    You only need to define BelongsTo() once in a script as it is global for all instances. 
+
+
  30. LoadRelations
    31. 
+
    Sometimes you want to load only a subset of data in a relationship. For example, you could load all female children sorted by children.name
+using LoadRelations($relation, $whereOrderBy = '', $offset = -1, $limit = -1):
+
    +	# assume this has been called: 
+	#   ADODB_Active_Record::ClassHasMany('person', 'children','person_id');
+	$person = new person(); 
+	$person->Load('id=23');  
+	# Load doesn't load children until $person->children is accessed or LoadRelations is called:
+	$person->LoadRelations('children',"gender='F' order by name");
+
    
+
    Lastly, if you have lots of child data, you can define a window of data of records to load. In the following
+example, we load a window of 100 records at a time:
+
    +
+	# assume this has been called: 
+	#  ADODB_Active_Record::ClassHasMany('Account', 'transactions','account_id'); 
+	$acc = new Account();
+	$acc->Load('id=23');
+	
+	$start = 0;
+	while(true) {
+		$acc->LoadRelations('transactions',"tx_done=0 order by trxdate", $start, $start+100);
+		if (!$acc->transactions) break;
+		foreach ($acc->transactions as $k => $trx) {
+			## process
+			$trx->tx_done = 1;
+			$trx->save();
+		}
+		$start += 100;
+		unset($acc->transactions);
+
+
+	}
+
    
+
    The $offset is 0-based, and $limit is the number of records to retrieve. The default is to ignore $offset (-1) and $limit (-1).

    ADOConnection Supplement
    
+
+
  32. ADOConnection::GetActiveRecords()
    33. 
+
    
+This allows you to retrieve an array of ADOdb_Active_Records. Returns false if an error occurs.
+
    +$table = 'products';
+$whereOrderBy = "name LIKE 'A%' ORDER BY Name";
+$activeRecArr = $db->GetActiveRecords($table, $whereOrderBy);
+foreach($activeRecArr as $rec) {
+	$rec->id = rand();
+	$rec->save();
+}
+
    
+
    
+And to retrieve all records ordered by specific fields:
+
    +$whereOrderBy = "1=1 ORDER BY Name";
+$activeRecArr = $db->GetActiveRecords($table);
+
    
+
    
+To use bind variables (assuming ? is the place-holder for your database):
+
    +$activeRecArr = $db->GetActiveRecords($tableName, 'name LIKE ?',
+						array('A%'));
+
    
+
    You can also define the primary keys of the table by passing an array of field names:
+
    +$activeRecArr = $db->GetActiveRecords($tableName, 'name LIKE ?',
+						array('A%'), array('id'));
+
    
+
+
  33. ADOConnection::GetActiveRecordsClass()
    34. 
+
    
+This allows you to retrieve an array of objects derived from ADOdb_Active_Records. Returns false if an error occurs.
+
    +class Product extends ADOdb_Active_Record{};
+$table = 'products';
+$whereOrderBy = "name LIKE 'A%' ORDER BY Name";
+$activeRecArr = $db->GetActiveRecordsClass('Product',$table, $whereOrderBy);
+
+# the objects in $activeRecArr are of class 'Product'
+foreach($activeRecArr as $rec) {
+	$rec->id = rand();
+	$rec->save();
+}
+
    
+
    
+To use bind variables (assuming ? is the place-holder for your database):
+
    +$activeRecArr = $db->GetActiveRecordsClass($className,$tableName, 'name LIKE ?',
+						array('A%'));
+
    
+
    You can also define the primary keys of the table by passing an array of field names:
+
    +$activeRecArr = $db->GetActiveRecordsClass($className,$tableName, 'name LIKE ?',
+						array('A%'), array('id'));
+
    
+
+

+
+
  • ADOConnection::ErrorMsg()
    •

    Active Record eXtended
    
+
    This is the original one-to-many Active Record implementation submitted by
+Chris Ravenscroft  (chris#voilaweb.com). The reason why we are offering both versions is that the Extended version
+is more powerful but more complex. My personal preference is to keep it simpler, but your view may vary. 
+
    To use, just include adodb-active-recordx.inc.php instead of adodb-active-record.inc.php.
+
    It provides a new function called Find() that is quite intuitive to use as shown in the example below. It also supports loading all relationships using a single query (using joins).
+
    +<?php

    Todo (Code Contributions welcome)
    
+ 
    Check _original and current field values before update, only update changes. Also if the primary key value is changed, then on update, we should save and use the original primary key values in the WHERE clause!
+
+ 
    PHP5 specific:  Make GetActiveRecords*() return an Iterator.
+ 
    PHP5 specific: Change PHP5 implementation of Active Record to use __get() and __set() for better performance.
+
+
     Change Log
    
+
    0.93
+
    You can force column names to be quoted in INSERT and UPDATE statements, typically because you are using reserved words as column names by setting
+ADODB_Active_Record::$_quoteNames = true;
+
+
    0.92
+
    Fixed some issues with incompatible fetch modes (ADODB_FETCH_ASSOC) causing problems in UpdateActiveTable.
+
    Added support for functions that support predefining one-to-many relationships:
     
+  ClassHasMany ClassBelongsTo TableHasMany TableBelongsTo TableKeyHasMany TableKeyBelongsTo. 
    
+
    You can also define your child/parent class in these functions, instead of the default ADODB_Active_Record.
+
+
    0.91
+
    HasMany hardcoded primary key field name to "id". Fixed.
+
+
    0.90
+
    Support for belongsTo and hasMany. Thanks to Chris Ravenscroft (chris#voilaweb.com).
+
    Added LoadRelations().
+
+
    0.08
+Added support for assoc arrays in Set().
+
+
    0.07
+
    $ADODB_ASSOC_CASE=2 did not work properly. Fixed.
+
    Added === check in ADODB_SetDatabaseAdapter for $db, adodb-active-record.inc.php. Thx Christian Affolter.
+
+
    0.06
+
    Added ErrorNo().
+
    Fixed php 5.2.0 compat issues.
+ 
+
    0.05
+
    If inserting a record and the value of a primary key field is null, then we do not insert that field in as
+we assume it is an auto-increment field. Needed by mssql.
+
+
    0.04 5 June 2006 
    
+
    Added support for declaring table name in $_table in class declaration. Thx Bill Dueber for idea.
+
    Added find($where,$bindarr=false) method to retrieve an array of active record objects.
+
+
    0.03 
    
+- Now we only update fields that have changed, using $this->_original.
    
+- We do not include auto_increment fields in replace(). Thx Travis Cline
    
+- Added ADODB_ACTIVE_CACHESECS.
    
+
+
    0.02 
    
+- Much better error handling. ErrorMsg() implemented. Throw implemented if adodb-exceptions.inc.php detected.
    
+- You can now define the primary keys of the view or table you are accessing manually.
    
+- The Active Record allows you to create an object which does not have a primary key. You can INSERT but not UPDATE in this case.
+- Set() documented.
    
+- Fixed _pluralize bug with y suffix.
+
+
    
+ 0.01 6 Mar 2006
    
+- Fixed handling of nulls when saving (it didn't save nulls, saved them as '').
    
+- Better error handling messages.
    
+- Factored out a new method GetPrimaryKeys().

+Differences between ADOdb and ADO
    
+Database Driver Guide
    
+    Change Log
    
+
+
    Introduction
    
+
+
    PHP's database access functions are not standardised. This creates a need
+for a database class library to hide the differences between the different
+database API's (encapsulate the differences) so we can easily switch databases.
+PHP 4.0.5 or later is now required (because we use array-based str_replace).
    
+
+
    We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL
+Anywhere, Informix, PostgreSQL, FrontBase, SQLite, Interbase (Firebird and
+Borland variants), Foxpro, Access, ADO,
+DB2, SAP DB and ODBC. We have had successful reports of connecting to Progress
+and CacheLite via ODBC. We hope more people will contribute drivers to support
+other databases.
    
+
+
    PHP4 supports session variables. You can store your session information
+using ADOdb for true portability and scalability. See adodb-session.php for
+more information.
    
+
+
    Also read tips_portable_sql.htm
+for tips on writing portable SQL.
    
+
+
    Unique Features of ADOdb
    
+
+
      
+ 
    • Easy for Windows
+     programmers to adapt to because many of the conventions are similar to
+     Microsoft's ADO.
      • 
+ 
    • Unlike other PHP database
+     classes which focus only on select statements, we provide support code
+     to handle inserts and updates which can be adapted to multiple databases
+     quickly. Methods are provided for date handling, string concatenation
+     and string quoting characters for differing databases.
      • 
+ 
    • A metatype system is
+     built in so that we can figure out that types such as CHAR, TEXT and
+     STRING are equivalent in different databases.
      • 
+ 
    • Easy to port because
+     all the database dependant code are stored in stub functions. You do not
+     need to port the core logic of the classes.
      • 
+ 
    • Portable table and index
+     creation with the datadict classes. 
      •

    Installation Guide
    
+
+
    Make sure you are running PHP 4.0.5 or later. Unpack all the files into a
+directory accessible by your webserver.
    
+
+
    To test, try modifying some of the tutorial examples. Make sure you
+customize the connection settings correctly. You can debug using $db->debug
+= true as shown below:
    
+
+
    <?php
    
+         include('adodb/adodb.inc.php');
    
+         $db = ADONewConnection($dbdriver); # eg 'mysql' or 'postgres'
    
+         $db->debug = true;
    
+         $db->Connect($server, $user, $password, $database);
    
+         $rs = $db->Execute('select * from some_small_table');
    
+         print "<pre>";
    
+         print_r($rs->GetRows());
    
+         print "</pre>";

    Code Initialization Examples
    
+
+
    When running ADOdb, at least two files are loaded. First is
+adodb/adodb.inc.php, which contains all functions used by all database classes.
+The code specific to a particular database is in the
+adodb/driver/adodb-????.inc.php file.
    
+
+
    For example, to connect to a mysql database:
    
+
+
    include('/path/to/set/here/adodb.inc.php');
    
+$conn = &ADONewConnection('mysql');
    
+
+
    Whenever you need to connect to a database, you create a Connection object
+using the ADONewConnection($driver) function. NewADOConnection($driver)
+is an alternative name for the same function.
    
+
+
    At this point, you are not connected to the database (no longer true if you
+pass in a dsn). You will first need to decide whether
+to use persistent or non-persistent connections. The advantage of
+persistent connections is that they are faster, as the database
+connection is never closed (even when you call Close()). Non-persistent connections
+take up much fewer resources though, reducing the risk of your database and
+your web-server becoming overloaded. 
    
+
+
    For persistent connections, use $conn->PConnect(),
+or $conn->Connect() for non-persistent connections.
+Some database drivers also support NConnect(), which
+forces the creation of a new connection. 
    
+
+
    Connection Gotcha: If you create two connections, but both use the
+same userid and password, PHP will share the same connection. This can cause
+problems if the connections are meant to different databases. The solution is
+to always use different userid's for different databases, or use NConnect(). 
    
+
+
    Data Source Name (DSN) Support
    
+
+
    Since ADOdb 4.51, you can connect to a database by passing a dsn to
+NewADOConnection() (or ADONewConnection, which is the same function). The dsn
+format is: 
    
+
+
             $driver://$username:$password@hostname/$database?options[=value]
    
+
+
    NewADOConnection() calls Connect() or PConnect() internally for you. If the
+connection fails, false is returned. 
    
+
+
             # non-persistent connection
             $dsn = 'mysql://root:pwd@localhost/mydb'; 
             $db = NewADOConnection($dsn);
             if (!$db) die("Connection failed");   
             
             # no need to call connect/pconnect!
             $arr = $db->GetArray("select * from table");
             
             # persistent connection
    
+
             $dsn2 = 'mysql://root:pwd@localhost/mydb?persist'; 
+
    
+
             # non-persistent connection on port 3000
    
+
             $dsn2 = 'mysqli://root:pwd@localhost/mydb?persist=0&port=3000';
    
+
    
+
+
    If you have special characters such as /:?_ in your dsn, then you need to
+rawurlencode them first: 
    
+
+
             $pwd = rawurlencode($pwd);
    
+         $dsn = "mysql://root:$pwd@localhost/mydb";
             $dsn2=rawurlencode("sybase_ase")."://user:pass@host/path?query";
    
+
+
    Legal options are: 
    
+
+
    
+
+
+ 
+  
+  
+ 
+ 
+  
+  
+ 
+ 
+  
+  
+ 
+ 
+  
+  
+ 
+ 
+  
+  
+ 
+ 
+  
+  
+ 
+
    
+  
    For all drivers
    
+      		
+  
    'persist', 'persistent', 'debug', 'fetchmode', 'new' , 'cachesecs', 'memcache'
    
+  
    
+  
    Interbase/Firebird 
    
+      		
+  
    'dialect','charset','buffers','role' 
    
+  
    
+  
    M'soft ADO
    
+      		
+  
    'charpage' 
    
+  
    
+  
    MySQL
    
+      		
+  
    'clientflags' 
    
+  
    
+  
    MySQLi
    
+      		
+  
    'port', 'socket', 'clientflags' 
    
+  
    
+  
    Oci8
    
+      		
+  
    'nls_date_format','charset' 
    
+  
    
+
+
    
+
+
    For all drivers, when the options persist or persistent are
+set, a persistent connection is forced; similarly, when new is set, then
+a new connection will be created using NConnect if the underlying driver
+supports it. The debug option enables debugging. The fetchmode
+calls SetFetchMode(). If no value is defined for an
+option, then the value is set to 1. 
    
+
+
    Since ADOdb 5.09, we added 2 new parameters:
    
+
      
+
    • cachesecs which globally determines how many seconds to cache recordsets (default is 3600 secs if not defined) when
+CacheExecute() and CacheSelectLimit() are called and no cache-time parameter is passed into these functions.
+
    • memcache which defines the memcache host, port and whether to use compression. For example:
+
      +	# we have a memcache server at 10.1.1.22 using default port 11211, no compression
+	$dsn = 'mysql://user:pwd@localhost/mydb?memcache=10.1.1.22'; 
+	
+	# we have a memcache server 10.1.1.22 port 8888, compression=on
+	$dsn = 'mysql://user:pwd@localhost/mydb?memcache=10.1.1.22:8888:1';
+	 	
+	# we have a memcache servers mem1,mem2 on port 8888, compression=off
+	$dsn = 'mysql://user:pwd@localhost/mydb?memcache=mem1,mem2:8888:0'; 
+	
+	# we have a memcache servers mem1,mem2 on port 8888, compression=off and cachesecs=120
+	$dsn = 'mysql://user:pwd@localhost/mydb?memcache=mem1,mem2:8888:0&cachesecs=120';
+
      
+
    
+
+
    ADOdb DSN's are compatible with version 1.0 of PEAR DB's DSN format. 
    
+
+
    Examples of Connecting to Databases
    
+
+
    MySQL and Most Other Database Drivers
    
+
+
    MySQL connections are very
+straightforward, and the parameters are identical to mysql_connect:
    
+
+
             $conn = &ADONewConnection('mysql'); 
    
+         $conn->PConnect('localhost','userid','password','database');
    
+         
    
+             # or dsn 
             $dsn = 'mysql://user:pwd@localhost/mydb'; 
             $conn = ADONewConnection($dsn);  # no need for Connect()
             
             # or persistent dsn
             $dsn = 'mysql://user:pwd@localhost/mydb?persist'; 
             $conn = ADONewConnection($dsn);  # no need for PConnect()
             
             # a more complex example:
             $pwd = urlencode($pwd);
             $flags =  MYSQL_CLIENT_COMPRESS;
             $dsn = "mysql://user:$pwd@localhost/mydb?persist&clientflags=$flags";
             $conn = ADONewConnection($dsn);  # no need for PConnect()
     
    
+
+
    For most drivers, you can use the
+standard function: Connect($server, $user, $password, $database), or a DSN since ADOdb 4.51. Exceptions to this are listed
+below. 
    
+
+
    PDO
    
+
+
    PDO, which only works with PHP5, accepts a
+driver specific connection string: 
    
+
+
     
             $conn =& NewADConnection('pdo');
             $conn->Connect('mysql:host=localhost',$user,$pwd,$mydb);
             $conn->Connect('mysql:host=localhost;dbname=mydb',$user,$pwd);
             $conn->Connect("mysql:host=localhost;dbname=mydb;username=$user;password=$pwd");
    
+
+
    The DSN mechanism is also supported: 
    
+
+
     
             $conn =& NewADConnection("pdo_mysql://user:pwd@localhost/mydb?persist"); # persist is optional
    
+
+
    PostgreSQL
    
+
+
    PostgreSQL 7 and 8 accepts connections using:
+
    
+
+
    a. the standard connection string:
    
+
+
             $conn = &ADONewConnection('postgres');  
    
+         $conn->PConnect('host=localhost port=5432 dbname=mary');
    
+
+
    b. the classical 4 parameters:
    
+
+
             $conn->PConnect('localhost','userid','password','database');
    
+ 
    
+
+
    c. dsn: 
    
+
+
             $dsn = 'postgres://user:pwd@localhost/mydb?persist';  # persist is optional
             $conn = ADONewConnection($dsn);  # no need for Connect/PConnect
    
+
+
+
+
    LDAP
    
+
+
    Here is an example of querying a LDAP server. Thanks to Josh Eldridge for
+the driver and this example: 
    
+
+
     
    require('/path/to/adodb.inc.php');
     
    /* Make sure to set this BEFORE calling Connect() */
    $LDAP_CONNECT_OPTIONS = Array(
             Array ("OPTION_NAME"=>LDAP_OPT_DEREF, "OPTION_VALUE"=>2),
             Array ("OPTION_NAME"=>LDAP_OPT_SIZELIMIT,"OPTION_VALUE"=>100),
             Array ("OPTION_NAME"=>LDAP_OPT_TIMELIMIT,"OPTION_VALUE"=>30),
             Array ("OPTION_NAME"=>LDAP_OPT_PROTOCOL_VERSION,"OPTION_VALUE"=>3),
             Array ("OPTION_NAME"=>LDAP_OPT_ERROR_NUMBER,"OPTION_VALUE"=>13),
             Array ("OPTION_NAME"=>LDAP_OPT_REFERRALS,"OPTION_VALUE"=>FALSE),
             Array ("OPTION_NAME"=>LDAP_OPT_RESTART,"OPTION_VALUE"=>FALSE)
    );
    $host = 'ldap.baylor.edu';
    $ldapbase = 'ou=People,o=Baylor University,c=US';
     
    $ldap = NewADOConnection( 'ldap' );
    $ldap->Connect( $host, $user_name='', $password='', $ldapbase );
     
    echo "<pre>";
     
    print_r( $ldap->ServerInfo() );
    $ldap->SetFetchMode(ADODB_FETCH_ASSOC);
    $userName = 'eldridge';
    $filter="(|(CN=$userName*)(sn=$userName*)(givenname=$userName*)(uid=$userName*))";
     
    $rs = $ldap->Execute( $filter );
    if ($rs)
             while ($arr = $rs->FetchRow()) {
                  print_r($arr);       
             }
     
    $rs = $ldap->Execute( $filter );
    if ($rs) 
             while (!$rs->EOF) {
                     print_r($rs->fields);     
                     $rs->MoveNext();
             } 
             
    print_r( $ldap->GetArray( $filter ) );
    print_r( $ldap->GetRow( $filter ) );
     
    $ldap->Close();
    echo "</pre>";
    
+
+
    Using DSN: 
    
+
+
     
    $dsn = "ldap://ldap.baylor.edu/ou=People,o=Baylor University,c=US";
    $db = NewADOConnection($dsn);
    
+
+
    Interbase/Firebird
    
+
+
    You define the database in the $host parameter: 
    
+
+
             $conn = &ADONewConnection('ibase'); 
    
+         $conn->PConnect('localhost:c:\ibase\profile.gdb','sysdba','masterkey');
    
+
+
    Or dsn: 
    
+
+
             $dsn = 'firebird://user:pwd@localhost/mydb?persist&dialect=3';  # persist is optional
    
+         $conn = ADONewConnection($dsn);  # no need for Connect/PConnect
    
+
+
    SQLite
    
+
+
    Sqlite will create the database file if it does not exist. 
    
+
+
             $conn = &ADONewConnection('sqlite');
             $conn->PConnect('c:\path\to\sqlite.db'); # sqlite will create if does not exist
    
+
+
    Or dsn: 
    
+
+
             $path = urlencode('c:\path\to\sqlite.db');
             $dsn = "sqlite://$path/?persist";  # persist is optional
             $conn = ADONewConnection($dsn);  # no need for Connect/PConnect
    
+
+
    Oracle (oci8)
    
+
+
    With oci8, you can connect in multiple ways. Note that oci8 works fine with
+newer versions of the Oracle, eg. 9i and 10g.
    
+
+
    a. PHP and Oracle reside on the same machine, use default SID.
    
+
+
             $conn->Connect(false, 'scott', 'tiger');
    
+
+
    b. TNS Name defined in tnsnames.ora (or ONAMES or HOSTNAMES), eg. 'myTNS'
    
+
+
             $conn->PConnect(false, 'scott', 'tiger', 'myTNS');
    
+
+
    or
    
+
+
             $conn->PConnect('myTNS', 'scott', 'tiger');
    
+
+
    c. Host Address and SID
    
+
+
     
             # with adodb 5.06 or 4.991 and later
             $conn->Connect('192.168.0.1', 'scott', 'tiger', "SID=$SID");
             
             # OR with all versions of ADOdb
             $conn->connectSID = true;
             $conn->Connect('192.168.0.1', 'scott', 'tiger', $SID);
             
    
+
+
    d. Host Address and Service Name
    
+
+
             $conn->Connect('192.168.0.1', 'scott', 'tiger', 'servicename');
    
+
+
    e. Oracle connection string: 
    
+
+
             $cstr = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=$host)(PORT=$port))
    
+                          (CONNECT_DATA=(SID=$sid)))";
    
+         $conn->Connect($cstr, 'scott', 'tiger');
    
+
+
    f. ADOdb dsn: 
    
+
+
             $dsn = 'oci8://user:pwd@tnsname/?persist';  # persist is optional
    
+         $conn = ADONewConnection($dsn);  # no need for Connect/PConnect
    
+         
    
+         $dsn = 'oci8://user:pwd@host/sid';
    
+         $conn = ADONewConnection($dsn);
    
+         
    
+         $dsn = 'oci8://user:pwd@/';   # oracle on local machine
    
+         $conn = ADONewConnection($dsn);
    
+
+
    You can also set the charSet for Oracle 9.2 and later, supported since PHP
+4.3.2, ADOdb 4.54: 
    
+
+
             $conn->charSet = 'we8iso8859p1';
    
+         $conn->Connect(...);
    
+         
    
+         # or
    
+         $dsn = 'oci8://user:pwd@tnsname/?charset=WE8MSWIN1252';
    
+         $db = ADONewConnection($dsn);
    
+
+
    DSN-less ODBC ( Access, MSSQL and DB2 examples)
    
+
+
    ODBC DSN's can be created in the ODBC control panel, or you can use a
+DSN-less connection.To use DSN-less connections with ODBC you need PHP 4.3 or
+later. 
    
+
+
    For Microsoft Access:
    
+
+
             $db =& ADONewConnection('access');
    
+         $dsn = "Driver={Microsoft Access Driver (*.mdb)};Dbq=d:\\northwind.mdb;Uid=Admin;Pwd=;";
             $db->Connect($dsn);
    
+
+
    For Microsoft SQL Server: 
    
+
+
             $db =& ADONewConnection('odbc_mssql');
    
+         $dsn = "Driver={SQL Server};Server=localhost;Database=northwind;";
    
+         $db->Connect($dsn,'userid','password');
    
+
+
    or if you prefer to use the mssql extension (which is
+limited to mssql 6.5 functionality): 
    
+
+
             $db =& ADONewConnection('mssql');
    
+         $db->Execute('localhost', 'userid', 'password', 'northwind');
    
+
+
    For DB2: 
    
+
+
     
             $dbms = 'db2'; # or 'odbc_db2' if db2 extension not available
             $db =& ADONewConnection($dbms);
             $dsn = "driver={IBM db2 odbc DRIVER};Database=sample;hostname=localhost;port=50000;protocol=TCPIP;".
                                       "uid=root; pwd=secret";
    
+         $db->Connect($dsn);
    
+		  # or connect and set schema
+		  $db->Connect($dsn,null,null,$schema);
    
+
    
+
+
    DSN-less Connections with ADO
    
+If you are using versions of PHP earlier than PHP 4.3.0, DSN-less connections
+only work with Microsoft's ADO,
+which is Microsoft's COM based API. An example using the ADOdb library and
+Microsoft's ADO:
+
    
+
+
    <?php
    
+         include('adodb.inc.php'); 
    
+         $db = &ADONewConnection("ado_mssql");
    
+         print "<h1>Connecting DSN-less $db->databaseType...</h1>";
    
+                 
    
+         $myDSN="PROVIDER=MSDASQL;DRIVER={SQL Server};"
    
+                 . "SERVER=flipper;DATABASE=ai;UID=sa;PWD=;"  ;
             $db->Connect($myDSN);
             
             $rs = $db->Execute("select * from table");
             $arr = $rs->GetArray();
             print_r($arr);
    ?>
    
+
+
    High Speed ADOdb - tuning tips
    
+
+
    ADOdb is a big class library, yet it consistently
+beats all other PHP class libraries in performance. This is because it is
+designed in a layered fashion, like an onion, with the fastest functions in the
+innermost layer. Stick to the following functions for best performance:
    
+
+
    
+
+
+ 
+  
+ 
+ 
+  
+ 
+
    
+  
    Innermost Layer
    
+  
    
+  
    Connect, PConnect, NConnect
    
+  Execute, CacheExecute
    
+  SelectLimit, CacheSelectLimit
    
+  MoveNext, Close 
    
+  qstr, Affected_Rows, Insert_ID
    
+  
    
+
+
    
+
+
    The fastest way to access the field data is by accessing the array
+$recordset->fields directly. Also set the global variables $ADODB_FETCH_MODE = ADODB_FETCH_NUM, and (for
+oci8, ibase/firebird and odbc) $ADODB_COUNTRECS
+= false before you connect to your database.
    
+
+
    Consider using bind parameters if your database supports it, as it improves
+query plan reuse. Use ADOdb's performance tuning system to identify bottlenecks
+quickly. At the time of writing (Dec 2003), this means oci8 and odbc drivers.
    
+
+
    Lastly make sure you have a PHP accelerator cache installed such as APC,
+Turck MMCache, Zend Accelerator or ionCube.

    Fastest data retrieval using ADOdb extension

+  
    $rs =& $rs->Execute($sql);
    
+while (!$rs->EOF) {
    
+           var_dump($rs->fields);
    
+           $rs->MoveNext();
    
+}
    
+      		
+  
    $rs =& $rs->Execute($sql);
    
+$array = adodb_getall($rs);
    
+var_dump($array);
    
+  
    
+  
    
+  
    
+
+
    
+
+
    Advanced Tips 
    
+
+
    If you have the ADOdb C
+extension installed, you can replace your calls to $rs->MoveNext() with
+adodb_movenext($rs). This doubles the speed of this operation. For retrieving
+entire recordsets at once, use GetArray(), which uses the high speed extension
+function adodb_getall($rs) internally. 
    
+
+
    Execute() is the default way to run queries. You can use the low-level
+functions _Execute() and _query() to reduce query overhead. Both these
+functions share the same parameters as Execute(). 
    
+
+
    If you do not have any bind parameters or your database supports binding
+(without emulation), then you can call _Execute() directly. Calling this
+function bypasses bind emulation. Debugging is still supported in _Execute(). 
    
+
+
    If you do not require debugging facilities nor emulated binding, and do not
+require a recordset to be returned, then you can call _query. This is great for
+inserts, updates and deletes. Calling this function bypasses emulated binding,
+debugging, and recordset handling. Either the resultid, true or false are
+returned by _query(). 
    
+
+
    For Informix, you can disable scrollable cursors with $db->cursorType =
+0. 
    
+
+
    Hacking ADOdb Safely
    
+
+
    You might want to modify ADOdb for your own purposes. Luckily you can still
+maintain backward compatibility by sub-classing ADOdb and using the
+$ADODB_NEWCONNECTION variable. $ADODB_NEWCONNECTION allows you to override the
+behaviour of ADONewConnection(). ADOConnection() checks for this variable and
+will call the function-name stored in this variable if it is defined. 
    
+
+
    In the following example, new functionality for the connection object is
+placed in the hack_mysql and hack_postgres7 classes. The
+recordset class naming convention can be controlled using $rsPrefix. Here we
+set it to 'hack_rs_', which will make ADOdb use hack_rs_mysql and hack_rs_postgres7
+as the recordset classes. 
    
+
+
    class hack_mysql extends adodb_mysql {
    
+var $rsPrefix = 'hack_rs_';
    
+  /* Your mods here */
    
+}
    
+
    
+class hack_rs_mysql extends ADORecordSet_mysql {
    
+          /* Your mods here */
    
+}
    
+
    
+class hack_postgres7 extends adodb_postgres7 {
    
+var $rsPrefix = 'hack_rs_';
    
+  /* Your mods here */
    
+}
    
+
    
+class hack_rs_postgres7 extends ADORecordSet_postgres7 {
    
+ /* Your mods here */
    
+}
    
+
    
+$ADODB_NEWCONNECTION = 'hack_factory';
    
+
    
+function& hack_factory($driver)
    
+{
    
+         if ($driver !== 'mysql' && $driver !== 'postgres7') return false;
    
+         
    
+         $driver = 'hack_'.$driver;
    
+         $obj = new $driver();
    
+         return $obj;
    
+}
    
+
    
+include_once('adodb.inc.php');
    
+
+
    Don't forget to call the constructor of the parent class in your
+constructor. If you want to use the default ADOdb drivers return false in the
+above hack_factory() function. Also you can define your own
+ADORecordSet_empty() class, by defining a class $$this->rsPrefix.'empty'
+since 4.96/5.02. 
    
+
+
    PHP5 Features
    
+
+
    ADOdb 4.02 or later will transparently determine which
+version of PHP you are using. If PHP5 is detected, the following features become
+available: 
    
+
+
      
+ 
    • PDO: PDO drivers
+     are available. See the connection examples. Currently
+     PDO drivers are not as powerful as native drivers, and should be treated
+     as experimental.
      • 
+ 
    • Foreach iterators:
+     This is a very natural way of going through a recordset: 
      • 
+
    
+
+
      $ADODB_FETCH_MODE = ADODB_FETCH_NUM;
    
+  $rs = $db->Execute($sql);
    
+  foreach($rs as $k => $row) {
    
+           echo "r1=".$row[0]." r2=".$row[1]."<br>";
    
+  }
    
+
+
      
+ 
    • Exceptions:
+     Just include adodb-exceptions.inc.php and you can now catch
+     exceptions on errors as they occur. 
      • 
+
    
+
+
      include("../adodb-exceptions.inc.php"); 
    
+  include("../adodb.inc.php");        
    
+  try { 
    
+           $db = NewADOConnection("oci8"); 
    
+           $db->Connect('','scott','bad-password'); 
    
+  } catch (exception $e) { 
    
+           var_dump($e); 
    
+           adodb_backtrace($e->gettrace());
    
+  } 
    
+
+
    Note that reaching EOF is not considered
+an error nor an exception.

    The "Tested" column indicates how extensively the code has been
+tested and used. 
    
+A = well tested and used by many people
    
+B = tested and usable, but some features might not be implemented
    
+C = user contributed or experimental driver. Might not fully support all of the
+latest features of ADOdb. 
    
+
+
    The column "RecordCount() usable" indicates whether RecordCount()
+return the number of rows, or returns -1 when a SELECT statement is executed.
+If this column displays Y/N then the RecordCount() is emulated when the global
+variable $ADODB_COUNTRECS=true (this is the default). Note that for large
+recordsets, it might be better to disable RecordCount() emulation because
+substantial amounts of memory are required to cache the recordset for counting.
+Also there is a speed penalty of 40-50% if emulation is required. This is
+emulated in most databases except for PostgreSQL and MySQL. This variable is
+checked every time a query is executed, so you can selectively choose which
+recordsets to count.

    Tutorials
    
+
+
    Example 1: Select Statement
    
+
+
    Task: Connect to the Access Northwind DSN, display the first 2 columns of
+each row.
    
+
+
    In this example, we create a ADOConnection object, which represents the
+connection to the database. The connection is initiated with PConnect, which is a persistent
+connection. Whenever we want to query the database, we call the ADOConnection.Execute()
+function. This returns an ADORecordSet object which is actually a cursor that
+holds the current row in the array fields[].
+We use MoveNext()
+to move from row to row.
    
+
+
    NB: A useful function that is not used in this example is SelectLimit,
+which allows us to limit the number of rows shown. 
    
+
+
    <?
    
+include('adodb.inc.php');    # load code common to ADOdb
    
+$conn = &ADONewConnection('access');        # create a connection
    
+$conn->PConnect('northwind');   # connect to MS-Access, northwind DSN
    
+$recordSet = &$conn->Execute('select * from products');
    
+if (!$recordSet) 
    
+         print $conn->ErrorMsg();
    
+else
    
+while (!$recordSet->EOF) {
    
+         print $recordSet->fields[0].' '.$recordSet->fields[1].'<BR>';
    
+         $recordSet->MoveNext();
    
+}
     
    $recordSet->Close(); # optional
    
+$conn->Close(); # optional
    
+
    
+
    ?>
    
+
+
    The $recordSet returned
+stores the current row in the $recordSet->fields
+array, indexed by column number (starting from zero). We use the MoveNext()
+function to move to the next row. The EOF
+property is set to true when end-of-file is reached. If an error occurs in
+Execute(), we return false instead of a recordset.
    
+
+
    The $recordSet->fields[]
+array is generated by the PHP database extension. Some database extensions only
+index by number and do not index the array by field name. To force indexing by
+name - that is associative arrays - use the SetFetchMode function. Each
+recordset saves and uses whatever fetch mode was set when the recordset was
+created in Execute() or SelectLimit(). 
    
+
+
             $db->SetFetchMode(ADODB_FETCH_NUM);
    
+         $rs1 = $db->Execute('select * from table');
    
+         $db->SetFetchMode(ADODB_FETCH_ASSOC);
    
+         $rs2 = $db->Execute('select * from table');
    
+         print_r($rs1->fields); # shows array([0]=>'v0',[1] =>'v1')
             print_r($rs2->fields); # shows array(['col1']=>'v0',['col2'] =>'v1')
    
+
+
    To get the number of rows in the select statement, you can use $recordSet->RecordCount().
+Note that it can return -1 if the number of rows returned cannot be determined.
    
+
+
    Example 2: Advanced Select with Field Objects
    
+
+
    Select a table, display the first two columns. If the second column is a
+date or timestamp, reformat the date to US format.
    
+
+
    <?
    
+include('adodb.inc.php');    # load code common to ADOdb
    
+$conn = &ADONewConnection('access');        # create a connection
    
+$conn->PConnect('northwind');   # connect to MS-Access, northwind dsn
    
+$recordSet = &$conn->Execute('select CustomerID,OrderDate from Orders');
    
+if (!$recordSet) 
    
+         print $conn->ErrorMsg();
    
+else
    
+while (!$recordSet->EOF) {
    
+         $fld = $recordSet->FetchField(1);
             $type = $recordSet->MetaType($fld->type);
    
+
    
+         if ( $type == 'D' || $type == 'T') 
    
+                 print $recordSet->fields[0].' '.
    
+                          $recordSet->UserDate($recordSet->fields[1],'m/d/Y').'<BR>';
    
+         else 
                     print $recordSet->fields[0].' '.$recordSet->fields[1].'<BR>';
    
+
    
+         $recordSet->MoveNext();
    
+}
    $recordSet->Close(); # optional
    
+$conn->Close(); # optional
    
+
    
+
    ?>
    
+
+
    In this example, we check the field type of the second column using FetchField().
+This returns an object with at least 3 fields.
    
+
+
      
+ 
    • name: name of column
      • 
+ 
    • type: native field
+     type of column
      • 
+ 
    • max_length: maximum
+     length of field. Some databases such as MySQL do not return the maximum
+     length of the field correctly. In these cases max_length will be set to
+     -1.
      • 
+
    
+
+
    We then use MetaType()
+to translate the native type to a generic type. Currently the following generic
+types are defined:
    
+
+
      
+ 
    • C: character fields
+     that should be shown in a <input type="text"> tag.
      • 
+ 
    • X: TeXt, large text
+     fields that should be shown in a <textarea>
      • 
+ 
    • B: Blobs, or Binary
+     Large Objects. Typically images. 
      • 
+ 
    • D: Date field
      • 
+ 
    • T: Timestamp field
      • 
+ 
    • L: Logical field
+     (boolean or bit-field)
      • 
+ 
    • I:  Integer
+     field
      • 
+ 
    • N: Numeric field.
+     Includes autoincrement, numeric, floating point, real and integer. 
      • 
+ 
    • R: Serial field.
+     Includes serial, autoincrement integers. This works for selected
+     databases. 
      • 
+
    
+
+
    If the metatype is of type date or timestamp, then we print it using the
+user defined date format with UserDate(), which converts the PHP SQL date string
+format to a user defined one. Another use for MetaType() is data validation before doing an SQL
+insert or update.
    
+
+
    Example 3: Inserting
    
+
+
    Insert a row to the Orders table containing dates and strings that need to
+be quoted before they can be accepted by the database, eg: the single-quote in
+the word John's.
    
+
+
    <?
    
+include('adodb.inc.php');    # load code common to ADOdb
    
+$conn = &ADONewConnection('access');        # create a connection
    
+
    
+$conn->PConnect('northwind');   # connect to MS-Access, northwind dsn
    
+$shipto = $conn->qstr("John's Old Shoppe");
    
+
    
+$sql = "insert into orders (customerID,ProfileID,OrderDate,ShipName) ";
    
+$sql .= "values ('ANATR',2,".$conn->DBDate(time()).",$shipto)";
    
+
    
+if ($conn->Execute($sql) === false) {
    
+         print 'error inserting: '.$conn->ErrorMsg().'<BR>';
    
+}
    
+?>
    
+
+
    In this example, we see the advanced date and quote handling facilities of
+ADOdb. The unix timestamp (which is a long integer) is appropriately formated
+for Access with DBDate(),
+and the right escape character is used for quoting the John's Old Shoppe,
+which is John''s Old Shoppe and not PHP's default John's
+Old Shoppe with qstr().
+
    
+
+
    Observe the error-handling of the Execute statement. False is returned by Execute() if
+an error occured. The error message for the last error that occurred is
+displayed in ErrorMsg().
+Note: php_track_errors might have to be enabled for error messages to be
+saved.
    
+
+
    Example 4: Debugging
    
+
+
    <?
    
+include('adodb.inc.php');    # load code common to ADOdb
    
+$conn = &ADONewConnection('access');        # create a connection
    
+$conn->PConnect('northwind');   # connect to MS-Access, northwind dsn
    
+$shipto = $conn->qstr("John's Old Shoppe");
    
+$sql = "insert into orders (customerID,ProfileID,OrderDate,ShipName) ";
    
+$sql .= "values ('ANATR',2,".$conn->FormatDate(time()).",$shipto)";
    
+$conn->debug = true;
    if ($conn->Execute($sql) === false) print 'error inserting';
    ?>
    
+
+
    In the above example, we have turned on debugging by setting debug = true.
+This will display the SQL statement before execution, and also show any error
+messages. There is no need to call ErrorMsg() in this case. For displaying the
+recordset, see the rs2html()
+example.
    
+
+
    Also see the section on Custom Error Handlers.
    
+
+
    Example 5: MySQL and Menus
    
+
+
    Connect to MySQL database agora, and generate a <select> menu
+from an SQL statement where the <option> captions are in the 1st column,
+and the value to send back to the server is in the 2nd column.
    
+
+
    <?

+$conn = &ADONewConnection('mysql');  # create a connection
    
+$conn->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
    
+$sql = 'select CustomerName, CustomerID from customers';
    
+$rs = $conn->Execute($sql);
    
+print $rs->GetMenu('GetCust','Mary Rosli');
    
+?>
    
+
+
    Here we define a menu named GetCust, with the menu option 'Mary Rosli'
+selected. See GetMenu(). We also have functions that return
+the recordset as an array: GetArray(), and as an associative array with the
+key being the first column: GetAssoc().

+

    <?
    
+include('adodb.inc.php');  # load code common to ADOdb
    
+$conn1 = &ADONewConnection('mysql');  # create a mysql connection
    
+$conn2 = &ADONewConnection('oracle');  # create a oracle connection
    
+
    
+$conn1->PConnect($server, $userid, $password, $database);
    
+$conn2->PConnect(false, $ora_userid, $ora_pwd, $oraname);
    
+
    
+$conn1->Execute('insert ...');
    
+$conn2->Execute('update ...');
    
+?>
    
+
+
    Example 7: Generating Update and Insert SQL
    
+
+
    Since ADOdb 4.56, we support AutoExecute(),
+which simplifies things by providing an advanced wrapper for GetInsertSQL() and
+GetUpdateSQL(). For example, an INSERT can be carried out with: 
    
+
+
     
        $record["firstname"] = "Bob"; 
        $record["lastname"] = "Smith"; 
        $record["created"] = time(); 
        $insertSQL = $conn->AutoExecute($rs, $record, 'INSERT'); 
    
+
+
    and an UPDATE with: 
    
+
+
     
        $record["firstname"] = "Caroline"; 
        $record["lastname"] = "Smith"; # Update Caroline's lastname from Miranda to Smith 
        $insertSQL = $conn->AutoExecute($rs, $record, 'UPDATE', 'id = 1'); 
    
+
+
    The rest of this section is out-of-date: 
    
+
+
    ADOdb 1.31 and later supports two new recordset functions: GetUpdateSQL( )
+and GetInsertSQL( ). This allow you to perform a "SELECT * FROM table
+query WHERE...", make a copy of the $rs->fields, modify the fields, and
+then generate the SQL to update or insert into the table automatically. 
    
+
+
    We show how the functions can be used when accessing a table with the
+following fields: (ID, FirstName, LastName, Created). 
    
+
+
    Before these functions can be called, you need to initialize the recordset by
+performing a select on the table. Idea and code by Jonathan Younger
+jyounger#unilab.com. Since ADOdb 2.42, you can pass a table name instead of a
+recordset into GetInsertSQL (in $rs), and it will generate an insert statement
+for that table.

+

    $ADODB_FORCE_TYPE
    
+
+
    The behaviour of AutoExecute(), GetUpdateSQL() and GetInsertSQL() when
+converting empty or null PHP variables to SQL is controlled by the global
+$ADODB_FORCE_TYPE variable. Set it to one of the values below. Default is
+ADODB_FORCE_VALUE (3): 
    
+
+
    0 = ignore empty fields. All empty fields in array are ignored.
    
+1 = force null. All empty, php null and string 'null' fields are changed to sql NULL values.
    
+2 = force empty. All empty, php null and string 'null' fields are changed to sql empty '' or 0 values.
    
+3 = force value. Value is left as it is. Php null and string 'null' are set to sql NULL values and 
    
+    empty fields '' are set to empty '' sql values.
    
+
    
+define('ADODB_FORCE_IGNORE',0);
    
+define('ADODB_FORCE_NULL',1);
    
+define('ADODB_FORCE_EMPTY',2);
    
+define('ADODB_FORCE_VALUE',3);
    
+
+
    Thanks to Niko (nuko#mbnet.fi) for the $ADODB_FORCE_TYPE code. 
    
+
+
    Note: the constant ADODB_FORCE_NULLS is obsolete since 4.52 and is ignored.
+Set $ADODB_FORCE_TYPE = ADODB_FORCE_NULL for equivalent behaviour. 
    
+
+
    Since 4.62, the table name to be used can be overridden by setting
+$rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is
+called. 
    
+
+
    Example 8: Implementing Scrolling with Next and Previous
    
+
+
    The following code creates a very simple recordset pager, where you can
+scroll from page to page of a recordset.
    
+
+
    include_once('../adodb.inc.php');
    
+include_once('../adodb-pager.inc.php');
    
+session_start();
    
+
    
+$db = NewADOConnection('mysql');
    
+
    
+$db->Connect('localhost','root','','xphplens');
    
+
    
+$sql = "select * from adoxyz ";
    
+
    
+$pager = new ADODB_Pager($db,$sql);
    
+$pager->Render($rows_per_page=5);
    
+
+
    This will create a basic record pager that looks like this:

    The number of rows to display at one time is controled by the Render($rows)
+method. If you do not pass any value to Render(), ADODB_Pager will default to
+10 records per page. 
    
+
+
    You can control the column titles by modifying your SQL (supported by most
+databases): 
    
+
+
    $sql = 'select id as "ID", firstname as "First Name", 
    
+                   lastname as "Last Name", created as "Date Created" 
    
+                 from adoxyz';
    
+
+
    The above code can be found in the adodb/tests/testpaging.php example
+included with this release, and the class ADODB_Pager in adodb/adodb-pager.inc.php.
+The ADODB_Pager code can be adapted by a programmer so that the text links can
+be replaced by images, and the dull white background be replaced with more
+interesting colors. 
    
+
+
    You can also allow display of html by setting $pager->htmlSpecialChars =
+false. 
    
+
+
    Some of the code used here was contributed by Iván Oliva and Cornel G.

+
    Example 9: Exporting in CSV or Tab-Delimited Format
    
+
+
    We provide some helper functions to export in comma-separated-value (CSV)
+and tab-delimited formats:
    
+
+
    include_once('/path/to/adodb/toexport.inc.php');
    
+include_once('/path/to/adodb/adodb.inc.php');
    
+
    
+
    $db = &NewADOConnection('mysql');
    
+$db->Connect($server, $userid, $password, $database);
    
+
    
+$rs = $db->Execute('select fname as "First Name", surname as "Surname" from table');
    
+
    
+print "<pre>";
    
+print rs2csv($rs); # return a string, CSV format
    
+
+
    print '<hr>';
    
+
    
+$rs->MoveFirst(); # note, some databases do not support MoveFirst
    
+print rs2tab($rs,false); # return a string, tab-delimited
    
+                                                     # false == suppress field names in first line
    
+
+
    print '<hr>';
    
+$rs->MoveFirst();
    
+rs2tabout($rs); # send to stdout directly (there is also an rs2csvout function)
    
+print "</pre>";
    
+
    
+$rs->MoveFirst();
    
+$fp = fopen($path, "w");
    
+if ($fp) {
    
+  rs2csvfile($rs, $fp); # write to file (there is also an rs2tabfile function)
    
+  fclose($fp);
    
+}
    
+
+
    Carriage-returns or newlines are converted to spaces. Field names are
+returned in the first line of text. Strings containing the delimiter character
+are quoted with double-quotes. Double-quotes are double-quoted again. This
+conforms to Excel import and export guide-lines. 
    
+
+
    All the above functions take as an optional last parameter, $addtitles which
+defaults to true. When set to false field names in the first line
+are suppressed. 
    
+
+
    Example 10: Recordset Filters
    
+
+
    Sometimes we want to pre-process all rows in a recordset before we use it.
+For example, we want to ucwords all text in recordset. 
    
+
+
    include_once('adodb/rsfilter.inc.php');
    
+include_once('adodb/adodb.inc.php');
    
+
    
+// ucwords() every element in the recordset
    
+function do_ucwords(&$arr,$rs)
    
+{
    
+         foreach($arr as $k => $v) {
    
+                 $arr[$k] = ucwords($v);
    
+         }
    
+}
    
+
    
+$db = NewADOConnection('mysql');
    
+$db->PConnect('server','user','pwd','db');
    
+
    
+$rs = $db->Execute('select ... from table');
    
+$rs = RSFilter($rs,'do_ucwords');
    
+
+
    The RSFilter function takes 2 parameters, the recordset, and the name
+of the filter function. It returns the processed recordset scrolled to
+the first record. The filter function takes two parameters, the current
+row as an array, and the recordset object. For future compatibility, you should
+not use the original recordset object. 
    
+
+
    Example 11: Smart Transactions
    
+
+
    The old way of doing transactions required you to use 
    
+
+
    $conn->BeginTrans();
    
+$ok = $conn->Execute($sql);
    
+if ($ok) $ok = $conn->Execute($sql2);
    
+if (!$ok) $conn->RollbackTrans();
    
+else $conn->CommitTrans();
    
+
+
    This is very complicated for large projects because you have
+to track the error status. Smart Transactions is much simpler. You start a
+smart transaction by calling StartTrans(): 
    
+
+
    $conn->StartTrans();
    
+$conn->Execute($sql);
    
+$conn->Execute($Sql2);
    
+$conn->CompleteTrans();
    
+
+
    CompleteTrans() detects when an SQL error occurs, and will
+Rollback/Commit as appropriate. To specificly force a rollback even if no error
+occured, use FailTrans(). Note that the rollback is done in CompleteTrans(),
+and not in FailTrans(). 
    
+
+
    $conn->StartTrans();
    
+$conn->Execute($sql);
    
+if (!CheckRecords()) $conn->FailTrans();
    
+$conn->Execute($Sql2);
    
+$conn->CompleteTrans();
    
+
+
    You can also check if a transaction has failed, using HasFailedTrans(),
+which returns true if FailTrans() was called, or there was an error in the SQL
+execution. Make sure you call HasFailedTrans() before you call CompleteTrans(),
+as it is only works between StartTrans/CompleteTrans. 
    
+
+
    Lastly, StartTrans/CompleteTrans is nestable, and only the outermost block
+is executed. In contrast, BeginTrans/CommitTrans/RollbackTrans is NOT nestable.
+
    
+
+
    $conn->StartTrans();
    
+$conn->Execute($sql);
    
+  $conn->StartTrans();    # ignored
      if (!CheckRecords()) $conn->FailTrans();
      $conn->CompleteTrans(); # ignored
    $conn->Execute($Sql2);
    $conn->CompleteTrans();
    
+
+
    Note: Savepoints are currently not supported. 
    
+
+
    Using Custom Error Handlers and PEAR_Error
    
+
+
    ADOdb supports PHP5 exceptions. Just include adodb-exceptions.inc.php
+and you can now catch exceptions on errors as they occur. 
    
+
+
             include("../adodb-exceptions.inc.php"); 
    
+         include("../adodb.inc.php");        
    
+         try { 
    
+                 $db = NewADOConnection("oci8://scott:bad-password@mytns/"); 
    
+         } catch (exception $e) { 
    
+                 var_dump($e); 
    
+                 adodb_backtrace($e->gettrace());
    
+         } 
    
+
+
    ADOdb also provides two custom handlers which you can modify for your needs.
+The first one is in the adodb-errorhandler.inc.php file. This makes use
+of the standard PHP functions error_reporting
+to control what error messages types to display, and trigger_error which invokes the default
+PHP error handler. 
    
+
+
    Including the above file will cause trigger_error($errorstring,E_USER_ERROR)
+to be called when
    
+(a) Connect() or PConnect() fails, or 
    
+(b) a function that executes SQL statements such as Execute() or SelectLimit()
+has an error.
    
+(c) GenID() appears to go into an infinite loop. 
    
+
+
    The $errorstring is generated by ADOdb and will contain useful debugging
+information similar to the error.log data generated below. This file
+adodb-errorhandler.inc.php should be included before you create any
+ADOConnection objects. 
    
+
+
    If you define error_reporting(0), no errors will be passed to the error
+handler. If you set error_reporting(E_ALL), all errors will be passed to the
+error handler. You still need to use ini_set("display_errors",
+"0" or "1") to control the display of errors. 
    
+
+
    <?php
    
+error_reporting(E_ALL); # pass any error messages triggered to error handler
    
+include('adodb-errorhandler.inc.php');
    include('adodb.inc.php');
    include('tohtml.inc.php');
    $c = NewADOConnection('mysql');
    $c->PConnect('localhost','root','','northwind');
    $rs=$c->Execute('select * from productsz'); #invalid table productsz');
    if ($rs) rs2html($rs);
    ?>
    
+
+
    If you want to log the error message, you can do so by defining the
+following optional constants ADODB_ERROR_LOG_TYPE and ADODB_ERROR_LOG_DEST.
+ADODB_ERROR_LOG_TYPE is the error log message type (see error_log in the PHP manual). In this case
+we set it to 3, which means log to the file defined by the constant
+ADODB_ERROR_LOG_DEST. 
    
+
+
    <?php
    
+error_reporting(E_ALL); # report all errors
    
+ini_set("display_errors", "0"); # but do not echo the errors
    
+define('ADODB_ERROR_LOG_TYPE',3);
    
+define('ADODB_ERROR_LOG_DEST','C:/errors.log');
    
+include('adodb-errorhandler.inc.php');
    include('adodb.inc.php');
    include('tohtml.inc.php');
     
    $c = NewADOConnection('mysql');
    $c->PConnect('localhost','root','','northwind');
    $rs=$c->Execute('select * from productsz'); ## invalid table productsz
    if ($rs) rs2html($rs);
    ?>
    
+
+
    The following message will be logged in the error.log file: 
    
+
+
    (2001-10-28 14:20:38) mysql error: [1146: Table 'northwind.productsz' doesn't exist] in
    
+ EXECUTE("select * from productsz")
    
+
+
    PEAR_ERROR
    
+
+
    The second error handler is adodb-errorpear.inc.php.
+This will create a PEAR_Error derived object whenever an error occurs. The last
+PEAR_Error object created can be retrieved using ADODB_Pear_Error(). 
    
+
+
    <?php
    
+include('adodb-errorpear.inc.php');
    include('adodb.inc.php');
    include('tohtml.inc.php');
    $c = NewADOConnection('mysql');
    $c->PConnect('localhost','root','','northwind');
    $rs=$c->Execute('select * from productsz'); #invalid table productsz');
    if ($rs) rs2html($rs);
    else {
             $e = ADODB_Pear_Error();
    
+         echo '<p>',$e->message,'</p>';
    }
    ?>
    
+
+
    You can use a PEAR_Error derived class by defining the constant
+ADODB_PEAR_ERROR_CLASS before the adodb-errorpear.inc.php file is included. For
+easy debugging, you can set the default error handler in the beginning of the
+PHP script to PEAR_ERROR_DIE, which will cause an error message to be printed,
+then halt script execution: 
    
+
+
    include('PEAR.php');
    
+PEAR::setErrorHandling('PEAR_ERROR_DIE');
    
+
+
    Note that we do not explicitly return a PEAR_Error object to you when an
+error occurs. We return false instead. You have to call ADODB_Pear_Error() to
+get the last error or use the PEAR_ERROR_DIE technique. 
    
+
+
    MetaError and MetaErrMsg
    
+
+
    If you need error messages that work across multiple databases, then use MetaError(), which returns a virtualized error number,
+based on PEAR DB's error number system, and MetaErrMsg().
+
    
+
+
    Error Messages
    
+
+
    Error messages are outputted using the static method
+ADOConnnection::outp($msg,$newline=true). By default, it sends the messages to
+the client. You can override this to perform error-logging. 
    
+
+
    Data Source Names
    
+
+
    We now support connecting using PEAR style DSN's. A DSN is a connection
+string of the form:
    
+
+
    $dsn = "$driver://$username:$password@$hostname/$databasename";
    
+
+
    An example:
    
+
+
       $username = 'root';
    
+   $password = '';
    
+   $hostname = 'localhost';
    
+   $databasename = 'xphplens';
    
+   $driver = 'mysql';
    
+   $dsn = "$driver://$username:$password@$hostname/$databasename"
    
+   $db = NewADOConnection(); 
    
+   # DB::Connect($dsn) also works if you include 'adodb/adodb-pear.inc.php' at the top
    
+   $rs = $db->query('select firstname,lastname from adoxyz');
    
+   $cnt = 0;
    
+   while ($arr = $rs->fetchRow()) {
    
+                 print_r($arr); print "<br>";
    
+   }
    
+
+

+format. 
    
+
+
    PEAR Compatibility
    
+
+
    We support DSN's (see above), and the following functions: 
    
+
+
     DB_Common
             query - returns PEAR_Error on error
             limitQuery - return PEAR_Error on error
             prepare - does not return PEAR_Error on error
             execute - does not return PEAR_Error on error
             setFetchMode - supports ASSOC and ORDERED
             errorNative
             quote
             nextID
             disconnect
             
             getOne
             getAssoc
             getRow
             getCol
             
     DB_Result
             numRows - returns -1 if not supported
             numCols
             fetchInto - does not support passing of fetchmode
             fetchRows - does not support passing of fetchmode
             free
    
+
+
    Caching of Recordsets
    
+
+
    ADOdb now supports caching of recordsets in the file system using the
+CacheExecute( ), CachePageExecute( ) and CacheSelectLimit( ) functions. There
+are similar to the non-cache functions, except that they take a new first
+parameter, $secs2cache. 
    
+
+
    An example: 
    
+
+
    include('adodb.inc.php'); # load code common to ADOdb
    
+$ADODB_CACHE_DIR = '/usr/ADODB_cache';
    
+$conn = &ADONewConnection('mysql');  # create a connection
    
+$conn->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
    
+$sql = 'select CustomerName, CustomerID from customers';
    
+$rs = $conn->CacheExecute(15,$sql);
    
+
+
    The first parameter is the number of seconds to cache the query. Subsequent
+calls to that query will used the cached version stored in $ADODB_CACHE_DIR. To
+force a query to execute and flush the cache, call CacheExecute() with the
+first parameter set to zero. Alternatively, use the CacheFlush($sql) call. 
    
+
+
    For the sake of security, we recommend you set register_globals=off in
+php.ini if you are using $ADODB_CACHE_DIR.
    
+
+
    In ADOdb 1.80 onwards, the secs2cache parameter is optional in
+CacheSelectLimit() and CacheExecute(). If you leave it out, it will use the
+$connection->cacheSecs parameter, which defaults to 60 minutes. The following
+are equivalent: 
    
+
+
     
      # (1)
      $rs = $db->SelectLimit(30, 'select * from table', 10);
      
      # (2)
      $db->cacheSsecs = 30;
      $rs = $db->SelectLimit('select * from table', 10);
      
             $conn->Connect(...);
    
+         $conn->cacheSecs = 3600*24; # cache 24 hours
    
+         $rs = $conn->CacheExecute('select * from table');
    
+
+
    Please note that magic_quotes_runtime should be turned off. Do not change
+$ADODB_FETCH_MODE (or SetFetchMode) as the cached recordset will use the
+$ADODB_FETCH_MODE set when the query was executed. 
    
+
+
    MemCache support
    
+
+
    You can also share cached recordsets on
+a memcache server. The memcache API supports one or more pooled hosts. Only if
+none of the pooled servers can be contacted will a connect error be generated.
+Example below: 
    
+
+
     
    $db = NewADOConnection($driver='mysql');
    $db->memCache = true;
    $db->memCacheHost = array($ip1, $ip2, $ip3); /// $db->memCacheHost = $ip1; will work too
    $db->memCachePort = 11211; /// this is default memCache port
    $db->memCacheCompress = false; /// Use 'true' to store the item compressed (uses zlib)
     
    $db->Connect(...);
    $db->CacheExecute($sql);
    
+
+
    More info on memcache can be found at http://www.danga.com/memcached/. 
    
+
+
    Caching API
    
+
+
    There is also a caching API since
+4.99/5.05. Two implementations of the API are already available providing file
+and memcache support. 
    
+
+
    The new API for creating your custom
+caching class uses 2 globals: 
    
+
+
      
+ 
    • $ADODB_CACHE_CLASS: name of caching class 
      • 
+ 
    • $ADODB_CACHE: instance of $ADODB_CACHE_CLASS 
      • 
+
    
+
+
     
    include "/path/to/adodb.inc.php";
    $ADODB_CACHE_CLASS = 'MyCacheClass';
     
    class MyCacheClass extends ADODB_Cache_File
    {
             var $createdir = false; // do not set this to true unless you use temp directories in cache path
             function writecache($filename, $contents,$debug=false){...}
             function &readcache($filename, &$err, $secs2cache, $rsClass){ ...}
              :
    }
     
    $DB = NewADOConnection($driver);
    $DB->Connect(...);  ## MyCacheClass created here and stored in $ADODB_CACHE global variable.
     
    $data = $rs->CacheGetOne($sql); ## MyCacheClass is used here for caching...

    Pivot Tables
    
+
+
    Since ADOdb 2.30, we support the generation of SQL to create pivot tables,
+also known as cross-tabulations. For further explanation read this DevShed Cross-Tabulation tutorial.
+We assume that your database supports the SQL case-when expression. 
    
+
+
    In this example, we will use the Northwind database from Microsoft. In the
+database, we have a products table, and we want to analyze this table by suppliers
+versus product categories. We will place the suppliers on each row, and
+pivot on categories. So from the table on the left, we generate the pivot-table
+on the right:
    
+
+
    
+
+
+ 
+

+    
    
+    
    supplier2
    
+        		
+    
    category2
    
+    
    
+  
    
+

+  
    
+  
    
+  
    
+
+
    
+
+
    The following code will generate the SQL for a cross-tabulation: 
    
+
+
    # Query the main "product" table
    
+# Set the rows to SupplierName
    
+# and the columns to the values of Categories
    
+# and define the joins to link to lookup tables 
    
+# "categories" and "suppliers"
    
+#
    
+ include "adodb/pivottable.inc.php";
    
+ $sql = PivotTableSQL(
    
+         $gDB,                                      # adodb connection
    
+         'products p ,categories c ,suppliers s',   # tables
    
+         'SupplierName',                             # rows (multiple fields allowed)
    
+         'CategoryName',                            # column to pivot on 
    
+         'p.CategoryID = c.CategoryID and s.SupplierID= p.SupplierID' # joins/where
    
+);
    
+
+
    This will generate the following SQL:
    
+
+
    SELECT SupplierName, 
    
+SUM(CASE WHEN CategoryName='Beverages' THEN 1 ELSE 0 END) AS
+"Beverages", 
    
+SUM(CASE WHEN CategoryName='Condiments' THEN 1 ELSE 0 END) AS
+"Condiments", 
    
+SUM(CASE WHEN CategoryName='Confections' THEN 1 ELSE 0 END) AS
+"Confections", 
    
+SUM(CASE WHEN CategoryName='Dairy Products' THEN 1 ELSE 0 END) AS
+"Dairy Products", 
    
+SUM(CASE WHEN CategoryName='Grains/Cereals' THEN 1 ELSE 0 END) AS
+"Grains/Cereals", 
    
+SUM(CASE WHEN CategoryName='Meat/Poultry' THEN 1 ELSE 0 END) AS
+"Meat/Poultry", 
    
+SUM(CASE WHEN CategoryName='Produce' THEN 1 ELSE 0 END) AS
+"Produce", 
    
+SUM(CASE WHEN CategoryName='Seafood' THEN 1 ELSE 0 END) AS
+"Seafood", 
    
+SUM(1) as Total 
    
+FROM products p ,categories c ,suppliers s WHERE p.CategoryID =
+c.CategoryID and s.SupplierID= p.SupplierID 
    
+GROUP BY SupplierName
    
+
+
    You can also pivot on numerical columns and generate totals by
+using ranges. This code was revised in ADODB 2.41 and is not backward
+compatible. The second example shows this:
    
+
+
     $sql = PivotTableSQL(
    
+         $gDB,                                       # adodb connection
    
+         'products p ,categories c ,suppliers s',    # tables
    
+         'SupplierName',                              # rows (multiple fields allowed)
       array(                                       # column ranges
             ' 0 '      => 'UnitsInStock <= 0',
             "1 to 5"   => '0 < UnitsInStock and UnitsInStock <= 5',
             "6 to 10"  => '5 < UnitsInStock and UnitsInStock <= 10',
             "11 to 15" => '10 < UnitsInStock and UnitsInStock <= 15',
             "16+"      => '15 < UnitsInStock'
             ),
             ' p.CategoryID = c.CategoryID and s.SupplierID= p.SupplierID', # joins/where
             'UnitsInStock',                             # sum this field
             'Sum '                                      # sum label prefix
    );
    
+
+
    Which generates: 
    
+
+
    SELECT SupplierName, 
    
+SUM(CASE WHEN UnitsInStock <= 0 THEN UnitsInStock ELSE 0 END) AS
+"Sum 0 ", 
    
+SUM(CASE WHEN 0 < UnitsInStock and UnitsInStock <= 5 THEN
+UnitsInStock ELSE 0 END) AS "Sum 1 to 5",
    
+SUM(CASE WHEN 5 < UnitsInStock and UnitsInStock <= 10 THEN UnitsInStock
+ELSE 0 END) AS "Sum 6 to 10",
    
+SUM(CASE WHEN 10 < UnitsInStock and UnitsInStock <= 15 THEN
+UnitsInStock ELSE 0 END) AS "Sum 11 to 15", 
    
+SUM(CASE WHEN 15 < UnitsInStock THEN UnitsInStock ELSE 0 END) AS
+"Sum 16+", 
    
+SUM(UnitsInStock) AS "Sum UnitsInStock", 
    
+SUM(1) as Total,
    
+FROM products p ,categories c ,suppliers s WHERE p.CategoryID =
+c.CategoryID and s.SupplierID= p.SupplierID 
    
+GROUP BY SupplierName

    Class Reference
    
+
+
    Function parameters with [ ] around them are optional.
    
+
+
    Global Variables
    
+
+
    $ADODB_COUNTRECS
    
+
+
    If the database driver API does not support counting the number of records
+returned in a SELECT statement, the function RecordCount() is emulated when the
+global variable $ADODB_COUNTRECS is set to true, which is the default. We
+emulate this by buffering the records, which can take up large amounts of
+memory for big recordsets. Set this variable to false for the best performance.
+This variable is checked every time a query is executed, so you can selectively
+choose which recordsets to count.
    
+
+
    $ADODB_CACHE_DIR
    
+
+
    If you are using recordset caching, this is the directory to save your
+recordsets in. Define this before you call any caching functions such as
+CacheExecute( ). We recommend setting register_globals=off in php.ini if
+you use this feature for security reasons.
    
+
+
    If you are using Unix and apache, you might need to set your cache directory
+permissions to something similar to the following:
    
+
+
    chown -R apache /path/to/adodb/cache
    
+chgrp -R apache /path/to/adodb/cache 
    
+
+
    $ADODB_ANSI_PADDING_OFF
    
+
+
    Determines whether to right trim CHAR fields (and also VARCHAR for
+ibase/firebird). Set to true to trim. Default is false. Currently works for
+oci8po, ibase and firebird drivers. Added in ADOdb 4.01. 
    
+
+
    $ADODB_LANG
    
+
+
    Determines the language used in MetaErrorMsg(). The default is 'en', for
+English. To find out what languages are supported, see the files in
+adodb/lang/adodb-$lang.inc.php, where $lang is the supported langauge. 
    
+
+
    $ADODB_FETCH_MODE
    
+
+
    This is a global variable that determines how arrays are retrieved by recordsets.
+The recordset saves this value on creation (eg. in Execute( ) or SelectLimit(
+)), and any subsequent changes to $ADODB_FETCH_MODE have no affect on existing
+recordsets, only on recordsets created in the future.
    
+
+
    The following constants are defined:
    
+
+
    define('ADODB_FETCH_DEFAULT',0);
    
+define('ADODB_FETCH_NUM',1);
    
+define('ADODB_FETCH_ASSOC',2);
    
+define('ADODB_FETCH_BOTH',3); 
    
+
+
    An example: 
    
+
+
             $ADODB_FETCH_MODE = ADODB_FETCH_NUM;
    
+         $rs1 = $db->Execute('select * from table');
    
+         $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC;
    
+         $rs2 = $db->Execute('select * from table');
    
+         print_r($rs1->fields); # shows array([0]=>'v0',[1] =>'v1')
             print_r($rs2->fields); # shows array(['col1']=>'v0',['col2'] =>'v1')
    
+
+
    As you can see in the above example, both recordsets store and use different
+fetch modes based on the $ADODB_FETCH_MODE setting when the recordset was
+created by Execute().
    
+
+
    If no fetch mode is predefined, the fetch mode defaults to
+ADODB_FETCH_DEFAULT. The behaviour of this default mode varies from driver to
+driver, so do not rely on ADODB_FETCH_DEFAULT. For portability, we recommend
+sticking to ADODB_FETCH_NUM or ADODB_FETCH_ASSOC. Many drivers do not support
+ADODB_FETCH_BOTH.
    
+
+
    SetFetchMode Function
    
+
+
    If you have multiple connection objects, and want to have different fetch
+modes for each connection, then use SetFetchMode.
+Once this function is called for a connection object, that connection object
+will ignore the global variable $ADODB_FETCH_MODE and will use the internal
+fetchMode property exclusively.
    
+
+
             $db->SetFetchMode(ADODB_FETCH_NUM);
    
+         $rs1 = $db->Execute('select * from table');
    
+         $db->SetFetchMode(ADODB_FETCH_ASSOC);
    
+         $rs2 = $db->Execute('select * from table');
    
+         print_r($rs1->fields); # shows array([0]=>'v0',[1] =>'v1')
             print_r($rs2->fields); # shows array(['col1']=>'v0',['col2'] =>'v1')
    
+
+
    To retrieve the previous fetch mode, you can use check the $db->fetchMode
+property, or use the return value of SetFetchMode( ). 
    
+
+
    ADODB_ASSOC_CASE
    
+
+
    You can control the associative fetch case for certain drivers which behave
+differently. For the sybase, oci8po, mssql, odbc and ibase drivers and all
+drivers derived from them, ADODB_ASSOC_CASE will by default generate recordsets
+where the field name keys are lower-cased. Use the constant ADODB_ASSOC_CASE to
+change the case of the keys. There are 3 possible values:
    
+
+
    0 = assoc lowercase field names. $rs->fields['orderid']
    
+1 = assoc uppercase field names. $rs->fields['ORDERID']
    
+2 = use native-case field names. $rs->fields['OrderID'] -- this is the
+default since ADOdb 2.90
    
+
+
    To use it, declare it before you incldue adodb.inc.php.
    
+
+
    define('ADODB_ASSOC_CASE', 2); # use native-case for ADODB_FETCH_ASSOC
    
+include('adodb.inc.php'); 
    
+
+
    $ADODB_FORCE_TYPE
    
+
+
    See the GetUpdateSQL tutorial. 
    
+
+
    $ADODB_QUOTE_FIELDNAMES

    autoRollback: Persistent connections are auto-rollbacked in PConnect(
+) if this is set to true. Default is false.
    
+

    ADOConnection Main Functions
    
+
+
    ADOConnection( )
    
+
+
    Constructor function. Do not call this directly. Use ADONewConnection( )
+instead.
    
+
+
    Connect($host,[$user],[$password],[$database])
    
+
+
    Non-persistent connect to data source or server $host, using userid $user
+and password $password. If the server supports multiple databases,
+connect to database $database. 
    
+
+
    Returns true/false depending on connection success. Since 4.23, null is
+returned if the extension is not loaded.
    
+
+
    ADO Note: If
+you are using a Microsoft ADO and not OLEDB, you can set the $database
+parameter to the OLEDB data provider you are using.
    
+
+
    PostgreSQL: An alternative way of connecting to the database is to pass the
+standard PostgreSQL connection string in the first parameter $host, and the
+other parameters will be ignored.
    
+
+
    For Oracle and Oci8, there are two ways to connect. First is to use the TNS
+name defined in your local tnsnames.ora (or ONAMES or HOSTNAMES). Place the
+name in the $database field, and set the $host field to false. Alternatively,
+set $host to the server, and $database to the database SID, this bypassed
+tnsnames.ora. 
    
+
+
    Examples: 
    
+
+
     # $oraname in tnsnames.ora/ONAMES/HOSTNAMES
    
+ $conn->Connect(false, 'scott', 'tiger', $oraname); 
    
+ $conn->Connect('server:1521', 'scott', 'tiger', 'ServiceName'); # bypass tnsnames.ora
    
+
+
    There are many examples of connecting to a database. See Connection Examples for many examples. 
    
+
+
    PConnect($host,[$user],[$password],[$database])
    
+
+
    Persistent connect to data source or server $host, using userid $user
+and password $password. If the server supports multiple databases,
+connect to database $database.
    
+
+
    We now perform a rollback on persistent connection for selected databases
+since 2.21, as advised in the PHP manual. See change log or source code for
+which databases are affected. 
    
+
+
    Returns true/false depending on connection. Since 4.23, 0 is returned if the
+extension is not loaded. See Connect( ) above for more info.
    
+
+
    Since ADOdb 2.21, we also support autoRollback. If you set:
    
+
+
     $conn = &NewADOConnection('mysql');
    
+ $conn->autoRollback = true; # default is false
    
+ $conn->PConnect(...); # rollback here
    
+
+
    Then when doing a persistent connection with PConnect( ), ADOdb will perform
+a rollback first. This is because it is documented that PHP is not guaranteed
+to rollback existing failed transactions when persistent connections are used.
+This is implemented in Oracle, MySQL, PgSQL, MSSQL, ODBC currently. 
    
+
+
    Since ADOdb 3.11, you can force non-persistent connections even if PConnect
+is called by defining the constant ADODB_NEVER_PERSIST before you call
+PConnect. 
    
+
+
    Since 4.23, null is returned if the extension is not loaded. 
    
+
+
    NConnect($host,[$user],[$password],[$database])
    
+
+
    Always force a new connection. In contrast, PHP sometimes reuses connections
+when you use Connect() or PConnect(). Currently works only on mysql (PHP 4.3.0
+or later), postgresql and oci8-derived drivers. For other drivers, NConnect()
+works like Connect().
    
+
+
    IsConnected( )
    
+
+
    Returns true if connected to database. Added in 4.53. 
    
+
+
    Execute($sql,$inputarr=false)
    
+
+
    Execute SQL statement $sql and return derived class of ADORecordSet
+if successful. Note that a record set is always returned on success, even if we
+are executing an insert or update statement. You can also pass in $sql a
+statement prepared in Prepare().
    
+
+
    Returns derived class of ADORecordSet. Eg. if connecting via mysql, then
+ADORecordSet_mysql would be returned. False is returned if there was an error
+in executing the sql.
    
+
+
    The $inputarr parameter can be used for binding variables to parameters.
+Below is an Oracle example:
    
+
+
     $conn->Execute("SELECT * FROM TABLE WHERE COND=:val", array('val'=> $val));
    
+ 
    
+
+
    Another example, using ODBC,which uses the ? convention:
    
+
+
      $conn->Execute("SELECT * FROM TABLE WHERE COND=?", array($val));
    
+
+
    Binding variables
    
+
+
    Variable binding speeds the compilation and caching of SQL statements,
+leading to higher performance. Currently Oracle, Interbase and ODBC supports
+variable binding. Interbase/ODBC style ? binding is emulated in databases that
+do not support binding. Note that you do not have to quote strings if you use
+binding. 
    
+
+
    Variable binding in the odbc, interbase and oci8po drivers. 
    
+
+
    $rs = $db->Execute('select * from table where val=?', array('10'));
    
+
+
    Variable binding in the oci8 driver: 
    
+
+
    $rs = $db->Execute('select name from table where val=:key', 
    
+  array('key' => 10));
    
+
+
    Bulk binding 
    
+
+
    Since ADOdb 3.80, we support bulk binding in Execute(), in which you pass in
+a 2-dimensional array to be bound to an INSERT/UPDATE or DELETE statement. And since ADOdb 5.11 this is
+disabled by default due to security issues. To enable, set $conn->bulkBind = true. 
    
+
+
    $arr = array(
    
+         array('Ahmad',32),
    
+         array('Zulkifli', 24),
    
+         array('Rosnah', 21)
    
+         );
    
+$ok = $db->Execute('insert into table (name,age) values (?,?)',$arr);
    
+
+
    This provides very high performance as the SQL statement is prepared first.
+The prepared statement is executed repeatedly for each array row until all rows
+are completed, or until the first error. Very useful for importing data. 
    
+
+
    CacheExecute([$secs2cache,]$sql,$inputarr=false)
    
+
+
    Similar to Execute, except that the recordset is cached for $secs2cache
+seconds in the $ADODB_CACHE_DIR directory, and $inputarr only accepts
+1-dimensional arrays. If CacheExecute() is called again with the same $sql,
+$inputarr, and also the same database, same userid, and the cached recordset
+has not expired, the cached recordset is returned. 
    
+
+
      include('adodb.inc.php'); 
    
+  include('tohtml.inc.php');
    
+  $ADODB_CACHE_DIR = '/usr/local/ADOdbcache';
    
+  $conn = &ADONewConnection('mysql'); 
    
+  $conn->PConnect('localhost','userid','password','database');
    
+  $rs = $conn->CacheExecute(15, 'select * from table'); # cache 15 secs
    
+  rs2html($rs); /* recordset to html table */  
    
+
+
    Alternatively, since ADOdb 1.80, the $secs2cache parameter is optional:
    
+
+
             $conn->Connect(...);
    
+         $conn->cacheSecs = 3600*24; // cache 24 hours
    
+         $rs = $conn->CacheExecute('select * from table');
    
+
+
    If $secs2cache is omitted, we use the value in
+$connection->cacheSecs (default is 3600 seconds, or 1 hour). Use
+CacheExecute() only with SELECT statements. 
    
+
+
    Performance note: I have done some benchmarks and found that they vary so
+greatly that it's better to talk about when caching is of benefit. When your
+database server is much slower than your Web server or the database is very
+overloaded then ADOdb's caching is good because it reduces the load on your
+database server. If your database server is lightly loaded or much faster than
+your Web server, then caching could actually reduce performance. 
    
+
+
    ExecuteCursor($sql,$cursorName='rs',$parameters=false)
    
+
+
    Execute an Oracle stored procedure, and returns an Oracle REF cursor
+variable as a regular ADOdb recordset. Does not work with any other database
+except oci8. Thanks to Robert Tuttle for the design. 
    
+
+
        $db = ADONewConnection("oci8"); 
    
+    $db->Connect("foo.com:1521", "uid", "pwd", "FOO"); 
    
+    $rs = $db->ExecuteCursor("begin :cursorvar := getdata(:param1); end;", 
    
+                                            'cursorvar',
    
+                                            array('param1'=>10)); 
    
+    # $rs is now just like any other ADOdb recordset object
    
+    rs2html($rs);
    
+
+
    ExecuteCursor() is a helper function that does the following internally: 
    
+
+
             $stmt = $db->Prepare("begin :cursorvar := getdata(:param1); end;", true); 
    
+         $db->Parameter($stmt, $cur, 'cursorvar', false, -1, OCI_B_CURSOR);
    
+         $rs = $db->Execute($stmt,$bindarr);
    
+
+
    ExecuteCursor only accepts 1 out parameter. So if you have 2 out parameters,
+use: 
    
+
+
             $vv = 'A%';
    
+         $stmt = $db->PrepareSP("BEGIN list_tabs(:crsr,:tt); END;");
    
+         $db->OutParameter($stmt, $cur, 'crsr', -1, OCI_B_CURSOR);
    
+         $db->OutParameter($stmt, $vv, 'tt', 32); # return varchar(32)
    
+         $arr = $db->GetArray($stmt);
    
+         print_r($arr);
    
+         echo " val = $vv"; ## outputs 'TEST'
    
+
+
    for the following PL/SQL: 
    
+
+
             TYPE TabType IS REF CURSOR RETURN TAB%ROWTYPE;
    
+
    
+         PROCEDURE list_tabs(tabcursor IN OUT TabType,tablenames IN OUT VARCHAR) IS
    
+         BEGIN
    
+                 OPEN tabcursor FOR SELECT * FROM TAB WHERE tname LIKE tablenames;
    
+                 tablenames := 'TEST';
    
+         END list_tabs;
    
+
+
    SelectLimit($sql,$numrows=-1,$offset=-1,$inputarr=false)
    
+
+
    Returns a recordset if successful. Returns false otherwise. Performs a
+select statement, simulating PostgreSQL's SELECT statement, LIMIT $numrows
+OFFSET $offset clause.
    
+
+
    In PostgreSQL, SELECT * FROM TABLE LIMIT 3 will return the first 3 records
+only. The equivalent is $connection->SelectLimit('SELECT
+* FROM TABLE',3). This functionality is simulated for databases
+that do not possess this feature.
    
+
+
    And SELECT * FROM TABLE LIMIT 3 OFFSET 2 will return records 3, 4 and 5 (eg.
+after record 2, return 3 rows). The equivalent in ADOdb is $connection->SelectLimit('SELECT * FROM TABLE',3,2).
    
+
+
    Note that this is the opposite of MySQL's LIMIT clause. You can also
+set $connection->SelectLimit('SELECT *
+FROM TABLE',-1,10) to get rows 11 to the last row.
    
+
+
    The last parameter $inputarr is for databases that support variable binding
+such as Oracle oci8. This substantially reduces SQL compilation overhead. Below
+is an Oracle example:
    
+
+
     $conn->SelectLimit("SELECT * FROM TABLE WHERE COND=:val", 100,-1,array('val'=> $val));
    
+ 
    
+
+
    The oci8po driver (oracle portable driver) uses the more standard bind
+variable of ?: 
    
+
+
     $conn->SelectLimit("SELECT * FROM TABLE WHERE COND=?", 100,-1,array('val'=> $val));
    
+
+
    Ron Wilson reports that SelectLimit does not work with UNIONs. 
    
+
+
    CacheSelectLimit([$secs2cache,] $sql,
+$numrows=-1,$offset=-1,$inputarr=false)
    
+
+
    Similar to SelectLimit, except that the recordset returned is cached for
+$secs2cache seconds in the $ADODB_CACHE_DIR directory. 
    
+
+
    Since 1.80, $secs2cache has been optional, and you can define the caching
+time in $connection->cacheSecs.
    
+
+
             $conn->Connect(...);
    
+   $conn->cacheSecs = 3600*24; // cache 24 hours
    
+         $rs = $conn->CacheSelectLimit('select * from table',10);
    
+
+
    CacheFlush($sql=false,$inputarr=false)
    
+
+
    Flush (delete) any cached recordsets for the SQL statement $sql in
+$ADODB_CACHE_DIR. 
    
+
+
    If no parameter is passed in, then all adodb_*.cache files are deleted. 
    
+
+
    CacheSelectLimit() rewrites the SQL query, so you won't be able to pass the
+SQL to CacheFlush. In this case, to flush the cached SQL recordset returned by
+CacheSelectLimit(), set $secs2cache to -1: 
    
+
+
     
             $db->CacheSelectLimit(-1, $sql, $nrows);
    
+
+
    If you want to flush all cached recordsets manually, execute the following
+PHP code (works only under Unix): 
    
+  system("rm -f `find
+".$ADODB_CACHE_DIR." -name adodb_*.cache`");
    
+
+
    For general cleanup of all expired files, you should use crontab on Unix,
+or at.exe on Windows, and a shell script similar to the following:
    
+#------------------------------------------------------ 
    
+# This particular example deletes files in the TMPPATH 
    
+# directory with the string ".cache" in their name that 
    
+# are more than 7 days old. 
    
+#------------------------------------------------------ 
    
+AGED=7 
    
+find ${TMPPATH} -mtime +$AGED | grep "\.cache" | xargs rm -f 
    
+
+
    MetaError($errno=false)
    
+
+
    Returns a virtualized error number, based on PEAR DB's error number system.
+You might need to include adodb-error.inc.php before you call this function.
+The parameter $errno is the native error number you want to convert. If you do
+not pass any parameter, MetaError will call ErrorNo() for you and convert it.
+If the error number cannot be virtualized, MetaError will return -1 (DB_ERROR).
    
+
+
    MetaErrorMsg($errno)
    
+
+
    Pass the error number returned by MetaError() for the equivalent textual
+error message.
    
+
+
    ErrorMsg()
    
+
+
    Returns the last status or error message. The error message is reset after
+every call to Execute(). 
    
+
+
    This can return a string even if no error occurs. In general you do not need
+to call this function unless an ADOdb function returns false on an error. 
    
+
+
    Note: If debug is enabled, the SQL error message is always displayed
+when the Execute function is called.
    
+
+
    ErrorNo()
    
+
+
    Returns the last error number. The error number is reset after every call to
+Execute(). If 0 is returned, no error occurred. 
    
+
+
    Note that old versions of PHP (pre 4.0.6) do not support error number for
+ODBC. In general you do not need to call this function unless an ADOdb function
+returns false on an error.
    
+
+
    IgnoreErrors($saveErrHandlers)
    
+
+
    Allows you to ignore errors so that StartTrans()/CompleteTrans() is not
+affected, nor is the default error handler called if an error occurs. Useful
+when you want to check if a field or table exists in a database without
+invoking an error if it does not exist. 
    
+
+
    Usage: 
    
+
+
     
    $saveErrHandlers = $conn->IgnoreErrors();
    $rs = $conn->Execute("select field from some_table_that_might_not_exist");
    $conn->IgnoreErrors($saveErrHandlers);
    
+
+
    Warning: do not call StartTrans()/CompleteTrans() inside a code block that
+is using IgnoreErrors(). 
    
+
+
    SetFetchMode($mode)
    
+
+
    Sets the current fetch mode for the connection and stores it in
+$db->fetchMode. Legal modes are ADODB_FETCH_ASSOC and ADODB_FETCH_NUM. For
+more info, see $ADODB_FETCH_MODE.
    
+
+
    Returns the previous fetch mode, which could be false if SetFetchMode( ) has
+not been called before.
    
+
+
    CreateSequence($seqName = 'adodbseq',$startID=1)
    
+
+
    Create a sequence. The next time GenID( ) is called, the value returned will
+be $startID. Added in 2.60. 
    
+
+
    DropSequence($seqName = 'adodbseq')
    
+
+
    Delete a sequence. Added in 2.60. 
    
+
+
    GenID($seqName = 'adodbseq',$startID=1)
    
+
+
    Generate a sequence number . Works for interbase, mysql, postgresql, oci8,
+oci8po, mssql, ODBC based (access,vfp,db2,etc) drivers currently. Uses $seqName
+as the name of the sequence. GenID() will automatically create the sequence for
+you if it does not exist (provided the userid has permission to do so).
+Otherwise you will have to create the sequence yourself. 
    
+
+
    If your database driver emulates sequences, the name of the table is the
+sequence name. The table has one column, "id" which should be of type
+integer, or if you need something larger - numeric(16). 
    
+
+
    For ODBC and databases that do not support sequences natively (eg mssql,
+mysql), we create a table for each sequence. If the sequence has not been
+defined earlier, it is created with the starting value set in $startID.
    
+
+
    Note that the mssql driver's GenID() before 1.90 used to generate 16 byte
+GUID's.
    
+
+
    UpdateBlob($table,$column,$val,$where)
    
+
+
    Allows you to store a blob (in $val) into $table into
+$column in a row at $where. 
    
+
+
    Usage: 
    
+
+
             # for oracle
    
+         $conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, empty_blob())');
    
+         $conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
    
+         
    
+         # non oracle databases
    
+         $conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)');
    
+         $conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
    
+
+
    Returns true if succesful, false otherwise. Supported by MySQL, PostgreSQL,
+Oci8, Oci8po and Interbase drivers. Other drivers might work, depending on the
+state of development.
    
+
+
    Note that when an Interbase blob is retrieved using SELECT, it still needs
+to be decoded using $connection->DecodeBlob($blob); to derive the original
+value in versions of PHP before 4.1.0. 
    
+
+
    For PostgreSQL, you can store your blob using blob oid's or as a bytea field.
+You can use bytea fields but not blob oid's currently with UpdateBlob( ).
+Conversely UpdateBlobFile( ) supports oid's, but not bytea data.
    
+
    
+If you do not pass in an oid, then UpdateBlob() assumes that you are storing in
+bytea fields. 
    
+
+
    If you do not have any blob fields, you can improve you can improve general
+SQL query performance by disabling blob handling with
+$connection->disableBlobs = true. 
    
+
+
    UpdateClob($table,$column,$val,$where)
    
+
+
    Allows you to store a clob (in $val) into $table into
+$column in a row at $where. Similar to UpdateBlob (see above), but for
+Character Large OBjects. 
    
+
+
    Usage: 
    
+
+
             # for oracle
    
+         $conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, empty_clob())');
    
+         $conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
    
+         
    
+         # non oracle databases
    
+         $conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, null)');
    
+         $conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
    
+
+
    UpdateBlobFile($table,$column,$path,$where,$blobtype='BLOB')
    
+
+
    Similar to UpdateBlob, except that we pass in a file path to where the blob
+resides. 
    
+
+
    For PostgreSQL, if you are using blob oid's, use this interface. This
+interface does not support bytea fields. 
    
+
+
    Returns true if successful, false otherwise. 
    
+
+
    BlobEncode($blob) 
    
+
+
    Some databases require blob's to be encoded manually before upload. Note if
+you use UpdateBlob( ) or UpdateBlobFile( ) the conversion is done automatically
+for you and you do not have to call this function. For PostgreSQL, currently,
+BlobEncode() can only be used for bytea fields. 
    
+
+
    Returns the encoded blob value. 
    
+
+
    Note that there is a connection property called blobEncodeType
+which has 3 legal values: 
    
+
+
    false - no need to perform encoding or decoding.
    
+'I' - blob encoding required, and returned encoded blob is a numeric value (no
+need to quote).
    
+'C' - blob encoding required, and returned encoded blob is a character value
+(requires quoting). 
    
+
+
    This is purely for documentation purposes, so that programs that accept
+multiple database drivers know what is the right thing to do when processing
+blobs. 
    
+
+
    BlobDecode($blob, $maxblobsize = false)
+
    
+
+
    Some databases require blob's to be decoded manually after doing a select
+statement. If the database does not require decoding, then this function will
+return the blob unchanged. Currently BlobDecode is only required for one
+database, PostgreSQL, and only if you are using blob oid's (if you are using
+bytea fields, we auto-decode for you). The default maxblobsize is set in
+$connection->maxblobsize, which is set to 256K in adodb 4.54. 
    
+
+
    In ADOdb 4.54 and later, the blob is the return value. In earlier versions,
+the blob data is sent to stdout.
    
+
+
    $rs = $db->Execute("select bloboid from postgres_table where id=$key");
    
+$blob = $db->BlobDecode( reset($rs->fields) );
    
+
+
    Replace($table, $arrFields,
+$keyCols,$autoQuote=false)
    
+
+
    Try to update a record, and if the record is not found, an insert statement
+is generated and executed. Returns 0 on failure, 1 if update statement worked,
+2 if no record was found and the insert was executed successfully. This differs
+from MySQL's replace which deletes the record and inserts a new record. This
+also means you cannot update the primary key. The only exception to this is
+Interbase and its derivitives, which uses delete and insert because of some
+Interbase API limitations. 
    
+
+
    The parameters are $table which is the table name, the $arrFields which is
+an associative array where the keys are the field names, and $keyCols is the
+name of the primary key, or an array of field names if it is a compound key. If
+$autoQuote is set to true, then Replace() will quote all values that are
+non-numeric; auto-quoting will not quote nulls. Note that auto-quoting will not
+work if you use SQL functions or operators. 
    
+
+
    Examples: 
    
+
+
    # single field primary key
    
+$ret = $db->Replace('atable', 
    
+         array('id'=>1000,'firstname'=>'Harun','lastname'=>'Al-Rashid'),
    
+         'id',$autoquote = true);  
    
+# generates UPDATE atable SET firstname='Harun',lastname='Al-Rashid' WHERE id=1000
    
+# or INSERT INTO atable (id,firstname,lastname) VALUES (1000,'Harun','Al-Rashid')
    
+
    
+# compound key
    
+$ret = $db->Replace('atable2', 
    
+         array('firstname'=>'Harun','lastname'=>'Al-Rashid', 'age' => 33, 'birthday' => 'null'),
    
+         array('lastname','firstname'),
    
+         $autoquote = true);
    
+
    
+# no auto-quoting
    
+$ret = $db->Replace('atable2', 
    
+         array('firstname'=>"'Harun'",'lastname'=>"'Al-Rashid'", 'age' => 'null'),
    
+         array('lastname','firstname'));    
    
+
+
    AutoExecute($table, $arrFields, $mode,
+$where=false, $forceUpdate=true,$magicq=false)
    
+
+
    Since ADOdb 4.56, you can automatically generate and execute INSERTs and
+UPDATEs on a given table with this function, which is a wrapper for
+GetInsertSQL() and GetUpdateSQL(). 
    
+
+
    AutoExecute() inserts or updates $table given an array of $arrFields, where
+the keys are the field names and the array values are the field values to
+store. Note that there is some overhead because the table is first queried to
+extract key information before the SQL is generated. We generate an INSERT or
+UPDATE based on $mode (see below). 
    
+
+
    Legal values for $mode are 
    
+
+
      
+ 
    • 'INSERT' or 1 or DB_AUTOQUERY_INSERT
+     
      • 
+ 
    • 'UPDATE' or 2 or
+     DB_AUTOQUERY_UPDATE 
      • 
+
    
+
+
    You have to define the constants DB_AUTOQUERY_UPDATE and DB_AUTOQUERY_INSERT
+yourself or include adodb-pear.inc.php. 
    
+
+
    The $where clause is required if $mode == 'UPDATE'. If $forceUpdate=false
+then we will query the database first and check if the field value returned by
+the query matches the current field value; only if they differ do we update
+that field. 
    
+
+
    Returns true on success, false on error. 
    
+
+
    An example of its use is: 
    
+
+
     
    $record["firstName"] = "Carol";
    $record["lasTname"] = "Smith"; 
    $conn->AutoExecute($table,$record,'INSERT');
    # executes "INSERT INTO $table (firstName,lasTname) values ('Carol',Smith')";
     
    $record["firstName"] = "Carol";
    $record["lasTname"] = "Jones"; 
    $conn->AutoExecute($table,$record,'UPDATE', "lastname like 'Sm%'");
    # executes "UPDATE $table SET firstName='Carol',lasTname='Jones' WHERE lastname like 'Sm%'";
    
+
+
    Note: One of the strengths of ADOdb's AutoExecute() is that only valid field
+names for $table are updated. If $arrFields contains keys that are invalid
+field names for $table, they are ignored. There is some overhead in doing this
+as we have to query the database to get the field names, but given that you are
+not directly coding the SQL yourself, you probably aren't interested in speed
+at all, but convenience. 
    
+
+
    Since 4.62, the table name to be used can be overridden by setting
+$rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is
+called. 
    
+
+
    Since 4.94, setting the global variable $ADODB_QUOTE_FIELDNAMES to true will
+force field names to be auto-quoted in AutoExecute(), GetInsertSQL() and
+GetUpdateSQL(). 
    
+
+
    GetUpdateSQL(&$rs, $arrFields,
+$forceUpdate=false,$magicq=false, $force=null)
    
+
+
    Generate SQL to update a table given a recordset $rs, and the modified
+fields of the array $arrFields (which must be an associative array holding the
+column names and the new values) are compared with the current recordset. If
+$forceUpdate is true, then we also generate the SQL even if $arrFields is
+identical to $rs->fields. Requires the recordset to be associative. $magicq
+is used to indicate whether magic quotes are enabled (see qstr()). The field
+names in the array are case-insensitive.
    
+
+
    Since 4.52, we allow you to pass the $force type parameter, and this
+overrides the $ADODB_FORCE_TYPE global
+variable. 
    
+
+
    Since 4.62, the table name to be used can be overridden by setting
+$rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is
+called. 
    
+
+
    GetInsertSQL(&$rs, $arrFields,$magicq=false,$force_type=false)
    
+
+
    Generate SQL to insert into a table given a recordset $rs. Requires the
+query to be associative. $magicq is used to indicate whether magic quotes are
+enabled (for qstr()). The field names in the array are case-insensitive.
    
+
+
    Since 2.42, you can pass a table name instead of a recordset into
+GetInsertSQL (in $rs), and it will generate an insert statement for that table.
+
    
+
+
    Since 4.52, we allow you to pass the $force_type parameter, and this
+overrides the $ADODB_FORCE_TYPE global
+variable. 
    
+
+
    Since 4.62, the table name to be used can be overridden by setting
+$rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is
+called. 
    
+
+
    PageExecute($sql, $nrows, $page, $inputarr=false)
+
    
+
+
    Used for pagination of recordset. $page is 1-based. See Example
+8.
    
+
+
    CachePageExecute($secs2cache, $sql, $nrows,
+$page, $inputarr=false) 
    
+
+
    Used for pagination of recordset. $page is 1-based. See Example
+8. Caching version of PageExecute.
    
+
+
    Close( )
    
+
+
    Close the database connection. PHP4 proudly states that we no longer have to
+clean up at the end of the connection because the reference counting mechanism
+of PHP4 will automatically clean up for us.
    
+
+
    StartTrans( )
    
+
+
    Start a monitored transaction. As SQL statements are executed, ADOdb will
+monitor for SQL errors, and if any are detected, when CompleteTrans() is
+called, we auto-rollback. 
    
+
+
    To understand why StartTrans() is superior to BeginTrans(), let us examine a
+few ways of using BeginTrans(). The following is the wrong way to use
+transactions: 
    
+
+
    $DB->BeginTrans();
    
+$DB->Execute("update table1 set val=$val1 where id=$id");
    
+$DB->Execute("update table2 set val=$val2 where id=$id");
    
+$DB->CommitTrans();
    
+
+
    because you perform no error checking. It is possible to update table1 and
+for the update on table2 to fail. Here is a better way: 
    
+
+
    $DB->BeginTrans();
    
+$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
    
+if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
    
+if ($ok) $DB->CommitTrans();
    
+else $DB->RollbackTrans();
    
+
+
    Another way is (since ADOdb 2.0): 
    
+
+
    $DB->BeginTrans();
    
+$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
    
+if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
    
+$DB->CommitTrans($ok);
    
+
+
    Now it is a headache monitoring $ok all over the place. StartTrans() is an
+improvement because it monitors all SQL errors for you. This is particularly
+useful if you are calling black-box functions in which SQL queries might be
+executed. Also all BeginTrans, CommitTrans and RollbackTrans calls inside a
+StartTrans block will be disabled, so even if the black box function does a
+commit, it will be ignored. 
    
+
+
    $DB->StartTrans();
    
+CallBlackBox();
    
+$DB->Execute("update table1 set val=$val1 where id=$id");
    
+$DB->Execute("update table2 set val=$val2 where id=$id");
    
+$DB->CompleteTrans();
    
+
+
    Note that a StartTrans blocks are nestable, the inner blocks are ignored. 
    
+
+
    CompleteTrans($autoComplete=true)
    
+
+
    Complete a transaction called with StartTrans(). This function monitors for
+SQL errors, and will commit if no errors have occured, otherwise it will
+rollback. Returns true on commit, false on rollback. If the parameter
+$autoComplete is true monitor sql errors and commit and rollback as
+appropriate. Set $autoComplete to false to force rollback even if no SQL error
+detected. 
    
+
+
    FailTrans( )
    
+
+
    Fail a transaction started with StartTrans(). The rollback will only occur
+when CompleteTrans() is called. 
    
+
+
    HasFailedTrans( )
    
+
+
    Check whether smart transaction has failed, eg. returns true if there was an
+error in SQL execution or FailTrans() was called. If not within smart
+transaction, returns false. 
    
+
+
    BeginTrans( )
    
+
+
    Begin a transaction. Turns off autoCommit. Returns true if successful. Some
+databases will always return false if transaction support is not available. Any
+open transactions will be rolled back when the connection is closed. Among the
+databases that support transactions are Oracle, PostgreSQL, Interbase, MSSQL,
+certain versions of MySQL, DB2, Informix, Sybase, etc.
    
+
+
    Note that StartTrans() and CompleteTrans() is a
+superior method of handling transactions, available since ADOdb 3.40. For a
+explanation, see the StartTrans() documentation. 
    
+
+
    You can also use the ADOdb error handler to die
+and rollback your transactions for you transparently. Some buggy database
+extensions are known to commit all outstanding tranasactions, so you might want
+to explicitly do a $DB->RollbackTrans() in your error handler for safety. 
    
+
+
    Detecting Transactions
    
+
+
    Since ADOdb 2.50, you are able to detect when you are inside a transaction.
+Check that $connection->transCnt > 0. This variable is incremented whenever
+BeginTrans() is called, and decremented whenever RollbackTrans() or
+CommitTrans() is called. 
    
+
+
    CommitTrans($ok=true)
    
+
+
    End a transaction successfully. Returns true if successful. If the database
+does not support transactions, will return true also as data is always
+committed. 
    
+
+
    If you pass the parameter $ok=false, the data is rolled back. See example in
+BeginTrans().
    
+
+
    RollbackTrans( )
    
+
+
    End a transaction, rollback all changes. Returns true if successful. If the
+database does not support transactions, will return false as data is never
+rollbacked. 
    
+
+
    SetTransactionMode($mode )
    
+
+
    SetTransactionMode allows you to pass in the transaction mode to use for all
+subsequent transactions. Note: if you have persistent connections and using
+mssql or mysql, you might have to explicitly reset your transaction mode at the
+beginning of each page request. This is only supported in postgresql, mssql,
+mysql with InnoDB and oci8 currently. For example: 
    
+
+
     
    $db->SetTransactionMode("SERIALIZABLE");
    $db->BeginTrans();
    $db->Execute(...); $db->Execute(...);
    $db->CommiTrans();
     
    $db->SetTransactionMode(""); // restore to default
    $db->StartTrans();
    $db->Execute(...); $db->Execute(...);
    $db->CompleteTrans();
    
+
+
    Supported values to pass in: 
    
+
+
      
+ 
    • READ UNCOMMITTED (allows
+     dirty reads, but fastest) 
      • 
+ 
    • READ COMMITTED (default
+     postgres, mssql and oci8) 
      • 
+ 
    • REPEATABLE READ (default
+     mysql) 
      • 
+ 
    • SERIALIZABLE (slowest and
+     most restrictive) 
      • 
+
    
+
+
    You can also pass in database specific values such as 'SNAPSHOT' for mssql
+or 'READ ONLY' for oci8/postgres. 
    
+
+
    See transaction levels for PostgreSQL,
+Oracle,
+MySQL,
+and MS SQL Server.
+
    
+
+
    GetAssoc($sql,$inputarr=false,$force_array=false,$first2cols=false)
    
+
+
    Returns an associative array for the given query $sql with optional bind
+parameters in $inputarr. If the number of columns returned is greater to two, a
+2-dimensional array is returned, with the first column of the recordset becomes
+the keys to the rest of the rows. If the columns is equal to two, a 1-dimensional
+array is created, where the the keys directly map to the values (unless
+$force_array is set to true, when an array is created for each value). 
    
+
+
    Examples:
    
+
+
    We have the following data in a recordset:
    
+
+
    row1: Apple, Fruit, Edible
    
+row2: Cactus, Plant, Inedible
    
+row3: Rose, Flower, Edible
    
+
+
    GetAssoc will generate the following 2-dimensional associative array:
    
+
+
    Apple => array[Fruit, Edible]
    
+Cactus => array[Plant, Inedible]
    
+Rose => array[Flower,Edible]
    
+
+
    If the dataset is:
    
+
+
    row1: Apple, Fruit
    
+row2: Cactus, Plant
    
+row3: Rose, Flower 
    
+
+
    GetAssoc will generate the following 1-dimensional associative array (with
+$force_array==false):
    
+
+
    Apple => Fruit
    
+Cactus=>Plant
    
+Rose=>Flower 
    
+
+
    The function returns:
    
+
+
    The associative array, or false if an error occurs.
    
+
+
    CacheGetAssoc([$secs2cache,] $sql,$inputarr=false,$force_array=false,$first2cols=false)
    
+
+
    Caching version of GetAssoc function above. 
    
+
+
    GetMedian($table, $field, $where='')
    
+
+
    Returns the median value of $field for $table. The $where clause is
+optional. If used, make sure the WHERE is included, as in "WHERE name >
+'A'". If an error occurs, false is returned. Since ADOdb 5.06 and PHP
+4.991. 
    
+
+
    GetOne($sql,$inputarr=false)
    
+
+
    Executes the SQL and returns the first field of the first row. The recordset
+and remaining rows are discarded for you automatically. If an error occur,
+false is returned; use ErrorNo() or ErrorMsg() to get the error details. Since
+4.96/5.00, we return null if no records were found. And since 4.991/5.06, you
+can have change the return value if no records are found using the global
+variable $ADODB_GETONE_EOF: $ADODB_GETONE_EOF = false;
    
+
+
    GetRow($sql,$inputarr=false)
    
+
+
    Executes the SQL and returns the first row as an array. The recordset and
+remaining rows are discarded for you automatically. If no records are returned,
+an empty array is returned. If an error occurs, false is returned.
    
+
+
    GetAll($sql,$inputarr=false)
    
+
+
    Executes the SQL and returns the all the rows as a 2-dimensional array. The
+recordset is discarded for you automatically. If an error occurs, false is
+returned. GetArray is a synonym for GetAll.
    
+
+
    GetCol($sql,$inputarr=false,$trim=false)
    
+
+
    Executes the SQL and returns all elements of the first column as a
+1-dimensional array. The recordset is discarded for you automatically. If an
+error occurs, false is returned.
    
+
+
    CacheGetOne([$secs2cache,] $sql,$inputarr=false),
+CacheGetRow([$secs2cache,] $sql,$inputarr=false),
+CacheGetAll([$secs2cache,] $sql,$inputarr=false),
+CacheGetCol([$secs2cache,]
+$sql,$inputarr=false,$trim=false)
    
+
+
    Similar to above Get* functions, except that the recordset is serialized and
+cached in the $ADODB_CACHE_DIR directory for $secs2cache seconds. Good for
+speeding up queries on rarely changing data. Note that the $secs2cache
+parameter is optional. If omitted, we use the value in
+$connection->cacheSecs (default is 3600 seconds, or 1 hour). 
    
+
+
    Prepare($sql )
    
+
+
    Prepares (compiles) an SQL query for repeated execution. Bind parameters are
+denoted by ?, except for the oci8 driver, which uses the traditional Oracle
+:varname convention. 
    
+
+
    Returns an array containing the original sql statement in the first array
+element; the remaining elements of the array are driver dependent. If there is
+an error, or we are emulating Prepare( ), we return the original $sql string.
+This is because all error-handling has been centralized in Execute( ).
    
+
+
    Prepare( ) cannot be used with functions that use SQL query rewriting
+techniques, e.g. PageExecute( ) and SelectLimit( ).
    
+
+
    Example:
    
+
+
    $stmt = $DB->Prepare('insert into table (col1,col2) values (?,?)');
    
+for ($i=0; $i < $max; $i++)
    
+         $DB->Execute($stmt,array((string) rand(), $i));
    
+
+
    Also see InParameter(), OutParameter() and PrepareSP() below. Only supported
+internally by interbase, oci8 and selected ODBC-based drivers, otherwise it is
+emulated. There is no performance advantage to using Prepare() with emulation. 
    
+
+
    Important: Due to limitations or bugs in PHP, if you are getting errors when
+you using prepared queries, try setting $ADODB_COUNTRECS = false before
+preparing. This behaviour has been observed with ODBC. 
    
+
+
    IfNull($field, $nullReplacementValue)
    
+
+
    Portable IFNULL function (NVL in Oracle). Returns a string that represents
+the function that checks whether a $field is null for the given database, and
+if null, change the value returned to $nullReplacementValue. Eg.
    
+
+
    $sql = 'SELECT '.$db->IfNull('name', "'- unknown -'"). ' FROM table';
    
+
+
    length
    
+
+
    This is not a function, but a property. Some databases have
+"length" and others "len" as the function to measure the
+length of a string. To use this property: 
    
+
+
      $sql = "SELECT ".$db->length."(field) from table";
    
+  $rs = $db->Execute($sql);
    
+
+
    random
    
+
+
    This is not a function, but a property. This is a string that holds the sql
+to generate a random number between 0.0 and 1.0 inclusive. 
    
+
+
    substr
    
+
+
    This is not a function, but a property. Some databases have
+"substr" and others "substring" as the function to retrieve
+a sub-string. To use this property: 
    
+
+
      $sql = "SELECT ".$db->substr."(field, $offset, $length) from table";
    
+  $rs = $db->Execute($sql);
    
+
+
    For all databases, the 1st parameter of substr is the field, the 2nd
+is the offset (1-based) to the beginning of the sub-string, and the 3rd is the
+length of the sub-string. 
    
+
+
    Param($name)
    
+
+
    Generates a bind placeholder portably. For most databases, the bind
+placeholder is "?". However some databases use named bind parameters
+such as Oracle, eg ":somevar". This allows us to portably define an
+SQL statement with bind parameters: 
    
+
+
    $sql = 'insert into table (col1,col2) values ('.$DB->Param('a').','.$DB->Param('b').')';
    
+# generates 'insert into table (col1,col2) values (?,?)'
    
+# or        'insert into table (col1,col2) values (:a,:b)    '
    
+$stmt = $DB->Prepare($sql);
    
+$stmt = $DB->Execute($stmt,array('one','two'));
    
+
+
    PrepareSP($sql, $cursor=false )
    
+
+
    When calling stored procedures in mssql and oci8 (oracle), and you might
+want to directly bind to parameters that return values, or for special LOB
+handling. PrepareSP() allows you to do so. 
    
+
+
    Returns the same array or $sql string as Prepare( ) above. If you do not
+need to bind to return values, you should use Prepare( ) instead.
    
+
+
    The 2nd parameter, $cursor is not used except with oci8. Setting it to true
+will force OCINewCursor to be called; this is to support output REF CURSORs. 
    
+
+
    For examples of usage of PrepareSP( ), see InParameter( ) below. 
    
+
+
    Note: in the mssql driver, preparing stored procedures requires a special
+function call, mssql_init( ), which is called by this function. PrepareSP( ) is
+available in all other drivers, and is emulated by calling Prepare( ). 
    
+
+
    InParameter($stmt, $var, $name, $maxLen = 4000,
+$type = false )
    
+
+
    Binds a PHP variable as input to a stored procedure
+variable. The parameter $stmt is the value returned by PrepareSP(), $var
+is the PHP variable you want to bind, $name is the name of the stored procedure
+variable. Optional is $maxLen, the maximum length of the data to bind,
+and $type which is database dependant. Consult mssql_bind and ocibindbyname docs at php.net for more
+info on legal values for $type. 
    
+
+
    InParameter() is a wrapper function that calls Parameter() with
+$isOutput=false. The advantage of this function is that it is self-documenting,
+because the $isOutput parameter is no longer needed. Only for mssql and oci8
+currently. 
    
+
+
    Here is an example using oci8: 
    
+
+
    # For oracle, Prepare and PrepareSP are identical
    $stmt = $db->PrepareSP(
             "declare RETVAL integer; 
    
+         begin
    
+         :RETVAL := SP_RUNSOMETHING(:myid,:group);
    
+         end;"    );
    
+$db->InParameter($stmt,$id,'myid');
    
+$db->InParameter($stmt,$group,'group',64);
    
+$db->OutParameter($stmt,$ret,'RETVAL');
    
+$db->Execute($stmt);
    
+
+
    The same example using mssql:
    
+
+
    # @RETVAL = SP_RUNSOMETHING @myid,@group
    $stmt = $db->PrepareSP('SP_RUNSOMETHING'); 
    
+# note that the parameter name does not have @ in front!
    $db->InParameter($stmt,$id,'myid');
    $db->InParameter($stmt,$group,'group',64);
    # return value in mssql - RETVAL is hard-coded name 
    
+$db->OutParameter($stmt,$ret,'RETVAL');
    
+$db->Execute($stmt); 
    
+
+
    Note that the only difference between the oci8 and mssql implementations is
+$sql.
    
+
+
    If $type parameter is set to false, in mssql, $type will be dynamicly
+determined based on the type of the PHP variable passed (string => SQLCHAR, boolean =>SQLINT1, integer
+=>SQLINT4 or float/double=>SQLFLT8). 
    
+
+
    In oci8, $type can be set to OCI_B_FILE (Binary-File), OCI_B_CFILE
+(Character-File), OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and
+OCI_B_ROWID (ROWID). To pass in a null, use
+$db->Parameter($stmt, $null=null, 'param'). 
    
+
+
    OutParameter($stmt, $var, $name, $maxLen = 4000,
+$type = false )
    
+
+
    Binds a PHP variable as output from a stored procedure
+variable. The parameter $stmt is the value returned by PrepareSP(), $var
+is the PHP variable you want to bind, $name is the name of the stored
+procedure variable. Optional is $maxLen, the maximum length of the data
+to bind, and $type which is database dependant. 
    
+
+
    OutParameter() is a wrapper function that calls Parameter() with
+$isOutput=true. The advantage of this function is that it is self-documenting,
+because the $isOutput parameter is no longer needed. Only for mssql and oci8
+currently. 
    
+
+
    For an example, see InParameter. 
    
+
+
    Parameter($stmt, $var, $name, $isOutput=false,
+$maxLen = 4000, $type = false )
    
+
+
    Note: This function is deprecated, because of the new InParameter() and
+OutParameter() functions. These are superior because they are self-documenting,
+unlike Parameter(). 
    
+
+
    Adds a bind parameter suitable for return values or special data handling
+(eg. LOBs) after a statement has been prepared using PrepareSP(). Only for
+mssql and oci8 currently. The parameters are:
    
+
    
+$stmt Statement returned by Prepare() or PrepareSP().
    
+$var PHP variable to bind to. Make sure you pre-initialize it!
    
+$name Name of stored procedure variable name to bind to.
    
+[$isOutput] Indicates direction of parameter 0/false=IN 1=OUT 2=
+IN/OUT. This is ignored in oci8 as this driver auto-detects the direction.
    
+[$maxLen] Maximum length of the parameter variable.
    
+[$type] Consult mssql_bind and ocibindbyname docs at php.net for more
+info on legal values for type.
    
+
+
    Lastly, in oci8, bind parameters can be reused without calling PrepareSP( ) or
+Parameters again. This is not possible with mssql. An oci8 example:
    
+
+
    $id = 0; $i = 0;
    
+$stmt = $db->PrepareSP( "update table set val=:i where id=:id");
    
+$db->Parameter($stmt,$id,'id');
    
+$db->Parameter($stmt,$i, 'i');
    
+for ($cnt=0; $cnt < 1000; $cnt++) {
    
+         $id = $cnt; 
    
+         $i = $cnt * $cnt; # works with oci8!
             $db->Execute($stmt); 
    
+}
    
+
+
    Bind($stmt, $var, $size=4001, $type=false, $name=false)
    
+
+
    This is a low-level function supported only by the oci8 driver. Avoid
+using unless you only want to support Oracle. The Parameter( ) function is
+the recommended way to go with bind variables.
    
+
+
    Bind( ) allows you to use bind variables in your sql statement. This binds a
+PHP variable to a name defined in an Oracle sql statement that was previously
+prepared using Prepare(). Oracle named variables begin with a colon, and ADOdb
+requires the named variables be called :0, :1, :2, :3, etc. The first
+invocation of Bind() will match :0, the second invocation will match :1, etc.
+Binding can provide 100% speedups for insert, select and update statements. 
    
+
+
    The other variables, $size sets the buffer size for data storage, $type is
+the optional descriptor type OCI_B_FILE (Binary-File), OCI_B_CFILE
+(Character-File), OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and
+OCI_B_ROWID (ROWID). Lastly, instead of using the default :0, :1, etc names,
+you can define your own bind-name using $name. 
    
+
+
    The following example shows 3 bind variables being used: p1, p2 and p3.
+These variables are bound to :0, :1 and :2.
    
+
+
    $stmt = $DB->Prepare("insert into table (col0, col1, col2) values (:0, :1, :2)");
    
+$DB->Bind($stmt, $p1);
    
+$DB->Bind($stmt, $p2);
    
+$DB->Bind($stmt, $p3);
    
+for ($i = 0; $i < $max; $i++) { 
    
+   $p1 = ?; $p2 = ?; $p3 = ?;
    
+   $DB->Execute($stmt);
    
+}
    
+
+
    You can also use named variables:
    
+
+
    $stmt = $DB->Prepare("insert into table (col0, col1, col2) values (:name0, :name1, :name2)");
    
+$DB->Bind($stmt, $p1, "name0");
    
+$DB->Bind($stmt, $p2, "name1");
    
+$DB->Bind($stmt, $p3, "name2");
    
+for ($i = 0; $i < $max; $i++) { 
    
+   $p1 = ?; $p2 = ?; $p3 = ?;
    
+   $DB->Execute($stmt);
    
+}
    
+
+
    LogSQL($enable=true)
    
+
+
    Call this method to install a SQL logging and timing
+function (using fnExecute). Then all SQL statements are logged into an
+adodb_logsql table in a database. If the adodb_logsql table does not exist,
+ADOdb will create the table if you have the appropriate permissions. Returns
+the previous logging value (true for enabled, false for disabled). Here are
+samples of the DDL for selected databases: 
    
+
+
                     mysql:
                     CREATE TABLE adodb_logsql (
                       created datetime NOT NULL,
                       sql0 varchar(250) NOT NULL,
                       sql1 text NOT NULL,
                       params text NOT NULL,
                       tracer text NOT NULL,
                       timer decimal(16,6) NOT NULL
                     )
                     
                     postgres:
                     CREATE TABLE adodb_logsql (
                       created timestamp NOT NULL,
                       sql0 varchar(250) NOT NULL,
                       sql1 text NOT NULL,
                       params text NOT NULL,
                       tracer text NOT NULL,
                       timer decimal(16,6) NOT NULL
                     )
                     
                     mssql:
                     CREATE TABLE adodb_logsql (
                       created datetime NOT NULL,
                       sql0 varchar(250) NOT NULL,
                       sql1 varchar(4000) NOT NULL,
                       params varchar(3000) NOT NULL,
                       tracer varchar(500) NOT NULL,
                       timer decimal(16,6) NOT NULL
                     )
                     
                     oci8:
                     CREATE TABLE adodb_logsql (
                       created date NOT NULL,
                       sql0 varchar(250) NOT NULL,
                       sql1 varchar(4000) NOT NULL,
                       params varchar(4000),
                       tracer varchar(4000),
                       timer decimal(16,6) NOT NULL
                     )
    
+
+
    Usage: 
    
+
+
             $conn->LogSQL(); // turn on logging
    
+           :
    
+         $conn->Execute(...);
    
+           :
    
+         $conn->LogSQL(false); // turn off logging
    
+         
    
+         # output summary of SQL logging results
    
+         $perf = NewPerfMonitor($conn);
    
+         echo $perf->SuspiciousSQL();
    
+         echo $perf->ExpensiveSQL();
    
+
+
    One limitation of logging is that rollback also prevents SQL from being
+logged. 
    
+
+
    If you prefer to use another name for the table used to store the SQL, you
+can override it by calling adodb_perf::table($tablename), where $tablename is
+the new table name (you will still need to manually create the table yourself).
+An example: 
    
+
+
             include('adodb.inc.php');
    
+         include('adodb-perf.inc.php');
    
+         adodb_perf::table('my_logsql_table');
    
+
+
    Also see Performance Monitor. 
    
+
+
    fnExecute and fnCacheExecute properties
    
+
+
    These two properties allow you to define bottleneck functions for all sql
+statements processed by ADOdb. This allows you to perform statistical analysis
+and query-rewriting of your sql. 
    
+
+
    Examples of fnExecute
    
+
+
    Here is an example of using fnExecute, to count all cached queries and
+non-cached queries, you can do this:
    
+
+
    # $db is the connection object
    function &CountExecs($db, $sql, $inputarray)
    {
    global $EXECS;
     
             if (!is_array(inputarray)) $EXECS++;
             # handle 2-dimensional input arrays
             else if (is_array(reset($inputarray))) $EXECS += sizeof($inputarray);
             else $EXECS++;
             
             # in PHP4.4 and PHP5, we need to return a value by reference
             $null = null;
             return $null;
    }
     
    # $db is the connection object
    function CountCachedExecs($db, $secs2cache, $sql, $inputarray)
    {
    
+global $CACHED; $CACHED++;
    
+}
    
+
    
+$db = NewADOConnection('mysql');
    
+$db->Connect(...);
    
+$db->fnExecute = 'CountExecs';
    
+$db->fnCacheExecute = 'CountCachedExecs';
    
+ :
    
+ :
    
+# After many sql statements:`
    
+printf("<p>Total queries=%d; total cached=%d</p>",$EXECS+$CACHED, $CACHED);
    
+
+
    The fnExecute function is called before the sql is parsed and executed, so
+you can perform a query rewrite. If you are passing in a prepared statement,
+then $sql is an array (see Prepare). The fnCacheExecute
+function is only called if the recordset returned was cached. The function
+parameters match the Execute and CacheExecute functions respectively, except
+that $this (the connection object) is passed as the first parameter.
    
+
+
    Since ADOdb 3.91, the behaviour of fnExecute varies depending on whether the
+defined function returns a value. If it does not return a value, then the $sql
+is executed as before. This is useful for query rewriting or counting sql
+queries. 
    
+
+
    On the other hand, you might want to replace the Execute function with one
+of your own design. If this is the case, then have your function return a
+value. If a value is returned, that value is returned immediately, without any
+further processing. This is used internally by ADOdb to implement LogSQL()
+functionality.

    ADOConnection Utility Functions
    
+
+
    BlankRecordSet([$queryid])
    
+
+
    No longer available - removed since 1.99.
    
+
+
    Concat($s1,$s2,....)
    
+
+
    Generates the sql string used to concatenate $s1, $s2, etc together. Uses
+the string in the concat_operator field to generate the concatenation. Override
+this function if a concatenation operator is not used, eg. MySQL.
    
+
+
    Returns the concatenated string.
    
+
+
    DBDate($date)
    
+
+
    Format the $date in the format the database accepts - the return
+string is also quoted. This is used when you are sending dates to the database
+(eg INSERT, UPDATE or where clause of SELECT statement). The $date
+parameter can be a PHP DateTime object (since ADOdb 5.09), a Unix integer timestamp or an ISO format Y-m-d. Uses the
+fmtDate field, which holds the format to use. If null or false or '' is passed
+in, it will be converted to an SQL null.
    
+
+
    Returns the date as a quoted string.
    
+
+
     
             $sql = "select * from atable where created > ".$db->DBDate("$year-$month-$day");
             $db->Execute($sql);
    
+
+
    Note to retrieve a date column in a specific format, use SQLDate.
+
    
+
+
    BindDate($date)
    
+
+
    Format the $date in the bind format the database accepts. Normally
+this means that the date string is not quoted, unlike DBDate, which quotes the
+string. 
    
+
+
     
             $sql = "select * from atable where created > ".$db->Param('0');
             // or
             $sql = "select * from atable where created > ?";
             $db->Execute($sql,array($db->BindDate("$year-$month-$day"));
    
+
+
    DBTimeStamp($ts)
    
+
+
    Format the timestamp $ts in the format the database accepts; this can
+be a PHP DateTime object (since ADOdb 5.09), a Unix integer timestamp or an ISO format Y-m-d H:i:s. Uses the fmtTimeStamp
+field, which holds the format to use. If null or false or '' is passed in, it
+will be converted to an SQL null.
    
+
+
    Returns the timestamp as a quoted string.
    
+
+
     
             $sql = "select * from atable where created > ".$db->DBTimeStamp("$year-$month-$day $hr:$min:$secs");
             $db->Execute($sql);
    
+
+
    BindTimeStamp($ts)
    
+
+
    Format the timestamp $ts in the bind format the database accepts.
+Normally this means that the timestamp string is not quoted, unlike
+DBTimeStamp, which quotes the string. 
    
+
+
     
             $sql = "select * from atable where created > ".$db->Param('0');
             // or
             $sql = "select * from atable where created > ?";
             $db->Execute($sql,array($db->BindTimeStamp("$year-$month-$day $hr:$min:$secs"));
    
+
+
    qstr($s,[$magic_quotes_enabled=false])
    
+
+
    Quotes a string to be sent to the database. The $magic_quotes_enabled
+parameter may look funny, but the idea is if you are quoting a string extracted
+from a POST/GET variable, then pass get_magic_quotes_gpc() as the second
+parameter. This will ensure that the variable is not quoted twice, once by qstr
+and once by the magic_quotes_gpc.
    
+
+
    Eg. $s = $db->qstr(HTTP_GET_VARS['name'],get_magic_quotes_gpc());
    
+
+
    Returns the quoted string.
    
+
+
    Quote($s)
    
+
+
    Quotes the string $s, escaping the database specific quote character as
+appropriate. Formerly checked magic quotes setting, but this was disabled since
+3.31 for compatibility with PEAR DB. 
    
+
+
    Affected_Rows( )
    
+
+
    Returns the number of rows affected by a update or delete statement. Returns
+false if function not supported.
    
+
+
    Not supported by interbase/firebird currently. 
    
+
+
    Insert_ID( )
    
+
+
    Returns the last autonumbering ID inserted. Returns false if function not
+supported. 
    
+
+
    Only supported by databases that support auto-increment or object id's, such
+as PostgreSQL, MySQL and MS SQL Server currently. PostgreSQL returns the OID,
+which can change on a database reload.
    
+
+
    RowLock($table,$where)
    
+
+
    Lock a table row for the duration of a transaction. For example to lock
+record $id in table1: 
    
+
+
             $DB->StartTrans();
    
+         $DB->RowLock("table1","rowid=$id");
    
+         $DB->Execute($sql1);
    
+         $DB->Execute($sql2);
    
+         $DB->CompleteTrans();
    
+
+
    Supported in db2, interbase, informix, mssql, oci8, postgres, sybase. 
    
+
+
    MetaDatabases()
    
+
+
    Returns a list of databases available on the server as an array. You have to
+connect to the server first. Only available for ODBC, MySQL and ADO.
    
+
+
    MetaTables($ttype = false, $showSchema = false,
+$mask=false)
    
+
+
    Returns an array of tables and views for the current database as an array.
+The array should exclude system catalog tables if possible. To only show
+tables, use $db->MetaTables('TABLES'). To show only views, use
+$db->MetaTables('VIEWS'). The $showSchema parameter currently works only for
+DB2, and when set to true, will add the schema name to the table, eg.
+"SCHEMA.TABLE". 
    
+
+
    You can define a mask for matching. For example, setting $mask = 'TMP%' will
+match all tables that begin with 'TMP'. Currently only mssql, oci8, odbc_mssql
+and postgres* support $mask. 
    
+
+
    MetaColumns($table,$notcasesensitive=true)
    
+
+
    Returns an array of ADOFieldObject's, one field object for every column of
+$table. A field object is a class instance with (name, type, max_length)
+defined. Currently Sybase does not recognise date types, and ADO cannot
+identify the correct data type (so we default to varchar). 
    
+
+
    The $notcasesensitive parameter determines whether we uppercase or lowercase
+the table name to normalize it (required for some databases). Does not work
+with MySQL ISAM tables. 
    
+
+
    For schema support, pass in the $table parameter,
+"$schema.$tablename". This is only supported for selected databases. 
    
+
+
    MetaColumnNames($table,$numericIndex=false)
    
+
+
    Returns an array of column names for $table. Since ADOdb 4.22, this is an
+associative array, with the keys in uppercase. Set $numericIndex=true if you
+want the old behaviour of numeric indexes (since 4.23). 
    
+
+
    e.g. array('FIELD1' => 'Field1', 'FIELD2'=>'Field2') 
    
+
+
    MetaPrimaryKeys($table, $owner=false) 
    
+
+
    Returns an array containing column names that are the primary keys of
+$table. Supported by mysql, odbc (including db2, odbc_mssql, etc), mssql,
+postgres, interbase/firebird, oci8 currently. 
    
+
+
    Views (and some tables) have primary keys, but sometimes this information is
+not available from the database. You can define a function
+ADODB_View_PrimaryKeys($databaseType, $database, $view, $owner) that should
+return an array containing the fields that make up the primary key. If that
+function exists, it will be called when MetaPrimaryKeys() cannot find a primary
+key for a table or view. 
    
+
+
    // In this example: dbtype = 'oci8', $db = 'mydb', $view = 'dataView', $owner = false 
    
+function ADODB_View_PrimaryKeys($dbtype,$db,$view,$owner)
    
+{
    
+         switch(strtoupper($view)) {
    
+         case 'DATAVIEW': return array('DATAID');
    
+         default: return false;
    
+         }
    
+}
    
+
    
+$db = NewADOConnection('oci8');
    
+$db->Connect('localhost','root','','mydb'); 
    
+$db->MetaPrimaryKeys('dataView');
    
+
+
    ServerInfo() 
    
+
+
    Returns an array of containing two elements 'description' and 'version'. The
+'description' element contains the string description of the database. The
+'version' naturally holds the version number (which is also a string).
    
+
+
    MetaForeignKeys($table, $owner=false,
+$upper=false) 
    
+
+
    Returns an associate array of foreign keys, or false if not supported. For
+example, if table profile has a foreign key where profile.deptkey points to
+dept_table.deptid, and profile.posn=posn_table.postionid and
+profile.poscategory=posn_table.category, then
+$conn->MetaForeignKeys('profile') will return 
    
+
+
             array(
    
+                 'dept_table' => array('deptkey=deptid'),
    
+                 'posn_table' => array('posn=positionid','poscategory=category')
    
+         )
    
+
+
    The optional schema or owner can be defined in $owner. If $upper is true,
+then the table names (array keys) are upper-cased. 
    
+
+
    
+
+
    
+
+
    
+
+
    ADORecordSet
    
+
+
    When an SQL statement successfully is executed by ADOConnection->Execute($sql),an ADORecordSet object is
+returned. This object contains a virtual cursor so we can move from row to row,
+functions to obtain information about the columns and column types, and helper
+functions to deal with formating the results to show to the user.
    
+
+
    ADORecordSet Fields
    
+
+
    fields: Array containing the current row. This is not associative,
+but is an indexed array from 0 to columns-1. See also the function Fields, which behaves like an associative array.
    
+
+
    dataProvider: The underlying mechanism used to connect to the
+database. Normally set to native, unless using odbc or ado.
    
+
+
    blobSize: Maximum size of a char, string or varchar object before it
+is treated as a Blob (Blob's should be shown with textarea's). See the MetaType function.
    
+
+
    sql: Holds the sql statement used to generate this record set.
    
+
+
    canSeek: Set to true if Move( ) function works.
    
+
+
    EOF: True if we have scrolled the cursor past the last record.
    
+
+
    ADORecordSet Functions
    
+
+
    ADORecordSet( )
    
+
+
    Constructer. Normally you never call this function yourself.
    
+
+
    GetAssoc([$force_array])
    
+
+
    Generates an associative array from the recordset. Note that is this
+function is also available in the connection object.
+More details can be found there.
    
+
+
    GetArray([$number_of_rows])
    
+
+
    Generate a 2-dimensional array of records from the current cursor position,
+indexed from 0 to $number_of_rows - 1. If $number_of_rows is undefined, till
+EOF.
    
+
+
    GetRows([$number_of_rows])
    
+
+
    Generate a 2-dimensional array of records from the current
+cursor position. Synonym for GetArray() for compatibility with Microsoft ADO. 
    
+
+
    GetMenu($name, [$default_str=''],
+[$blank1stItem=true], [$multiple_select=false], [$size=0], [$moreAttr=''])
    
+
+
    Generate a HTML menu
+(<select><option><option></select>). The first column
+of the recordset (fields[0]) will hold the string to display in the option
+tags. If the recordset has more than 1 column, the second column (fields[1]) is
+the value to send back to the web server.. The menu will be given the name $name.
+
    
+
+
    If $default_str is defined, then if $default_str == fields[0],
+that field is selected. If $blank1stItem is true, the first option is
+empty. You can also set the first option strings by setting $blank1stItem =
+"$value:$text".
    
+
+
    $Default_str can be array for a multiple select listbox.
    
+
+
    To get a listbox, set the $size to a non-zero value (or pass
+$default_str as an array). If $multiple_select is true then a listbox
+will be generated with $size items (or if $size==0, then 5 items)
+visible, and we will return an array to a server. Lastly use $moreAttr to
+add additional attributes such as javascript or styles. 
    
+
+
    Menu Example 1: GetMenu('menu1','A',true)
+will generate a menu: for
+the data (A,1), (B,2), (C,3). Also see example 5.
    
+
+
    Menu Example 2: For the same data, GetMenu('menu1',array('A','B'),false)
+will generate a menu with both A and B selected: 
    
+
    
+
+
    GetMenu2($name, [$default_str=''],
+[$blank1stItem=true], [$multiple_select=false], [$size=0], [$moreAttr=''])
    
+
+
    This is nearly identical to GetMenu, except that the $default_str is
+matched to fields[1] (the option values).
    
+
+
    Menu Example 3: Given the data in menu example 2, GetMenu2('menu1',array('1','2'),false)
+will generate a menu with both A and B selected in menu example 2, but this
+time the selection is based on the 2nd column, which holds the values to return
+to the Web server. 
    
+
+
    UserDate($str, [$fmt])
    
+
+
    Converts the date string $str to another format. The date format is
+Y-m-d, or Unix timestamp format. The default $fmt is Y-m-d.
    
+
+
    UserTimeStamp($str, [$fmt])
    
+
+
    Converts the timestamp string $str to another format. The timestamp
+format is Y-m-d H:i:s, as in '2002-02-28 23:00:12', or Unix timestamp format.
+UserTimeStamp calls UnixTimeStamp to parse $str, and $fmt
+defaults to Y-m-d H:i:s if not defined. 
    
+
+
    UnixDate($str)
    
+
+
    Parses the date string $str and returns it in unix mktime format (eg.
+a number indicating the seconds after January 1st, 1970). Expects the date to
+be in Y-m-d H:i:s format, except for Sybase and Microsoft SQL Server, where M d
+Y is also accepted (the 3 letter month strings are controlled by a global
+array, which might need localisation).
    
+
+
    This function is available in both ADORecordSet and ADOConnection since
+1.91.
    
+
+
    UnixTimeStamp($str)
    
+
+
    Parses the timestamp string $str and returns it in unix mktime format
+(eg. a number indicating the seconds after January 1st, 1970). Expects the date
+to be in "Y-m-d, H:i:s" (1970-12-24, 00:00:00) or "Y-m-d
+H:i:s" (1970-12-24 00:00:00) or "YmdHis" (19701225000000)
+format, except for Sybase and Microsoft SQL Server, where "M d Y
+h:i:sA" (Dec 25 1970 00:00:00AM) is also accepted (the 3 letter month
+strings are controlled by a global array, which might need localisation).
    
+
+
    This function is available in both ADORecordSet and ADOConnection since
+1.91. 
    
+
+
    OffsetDate($dayFraction, $basedate=false)
    
+
+
    Returns a string with the native SQL functions to calculate future and past
+dates based on $basedate in a portable fashion. If $basedate is not defined,
+then the current date (at 12 midnight) is used. Returns the SQL string that
+performs the calculation when passed to Execute(). 
    
+
+
    For example, in Oracle, to find the date and time that is 2.5 days from
+today, you can use:
    
+
+
    # get date one week from now
    
+$fld = $conn->OffsetDate(7); // returns "(trunc(sysdate)+7")
    # get date and time that is 60 hours from current date and time
    
+$fld = $conn->OffsetDate(2.5, $conn->sysTimeStamp); // returns "(sysdate+2.5)"
    
+
    
+$conn->Execute("UPDATE TABLE SET dodate=$fld WHERE ID=$id");
    
+
+
    This function is available for mysql, mssql, oracle, oci8 and postgresql
+drivers since 2.13. It might work with other drivers provided they allow
+performing numeric day arithmetic on dates.
    
+
+
    SQLDate($dateFormat, $basedate=false)
    
+
+
    Returns a string which contains the native SQL functions to
+format a date or date column $basedate. This is used when retrieving date
+columns in SELECT statements. For sending dates to the database (eg. in UPDATE,
+INSERT or the where clause of SELECT statements) use DBDate.
+It uses a case-sensitive $dateFormat, which supports: 
    
+
+
     
      Y: 4-digit Year
      Q: Quarter (1-4)
      M: Month (Jan-Dec)
      m: Month (01-12)
      d: Day (01-31)
      H: Hour (00-23)
      h: Hour (1-12)
      i: Minute (00-59)
      s: Second (00-60)
      A: AM/PM indicator
      w: day of week (0-6 or 1-7 depending on DB)
      l: day of week (as string - lowercase L)
      W: week in year (0..53 for MySQL, 1..53 for PostgreSQL and Oracle)
      
    
+
+
    All other characters are treated as strings. You can also use \ to escape
+characters. Available on selected databases, including mysql, postgresql,
+mssql, oci8 and DB2. 
    
+
+
    This is useful in writing portable sql statements that GROUP BY on dates.
+For example to display total cost of goods sold broken by quarter (dates are
+stored in a field called postdate): 
    
+
+
     $sqlfn = $db->SQLDate('Y-\QQ','postdate'); # get sql that formats postdate to output 2002-Q1
    
+ $sql = "SELECT $sqlfn,SUM(cogs) FROM table GROUP BY $sqlfn ORDER BY 1 desc";
    
+ 
    
+
+
    MoveNext( )
    
+
+
    Move the internal cursor to the next row. The $this->fields array
+is automatically updated. Returns false if unable to do so (normally because
+EOF has been reached), otherwise true. 
    
+
+
    If EOF is reached, then the $this->fields array is set to false (this was
+only implemented consistently in ADOdb 3.30). For the pre-3.30 behaviour of
+$this->fields (at EOF), set the global variable $ADODB_COMPAT_FETCH = true.
    
+
+
    Example:
    
+
+
    $rs = $db->Execute($sql);
    
+if ($rs) 
    
+         while (!$rs->EOF) {
    
+                 ProcessArray($rs->fields);         
    
+                 $rs->MoveNext();
    
+         } 
    
+
+
    Move($to)
    
+
+
    Moves the internal cursor to a specific row $to. Rows are zero-based
+eg. 0 is the first row. The fields array is automatically updated. For
+databases that do not support scrolling internally, ADOdb will simulate forward
+scrolling. Some databases do not support backward scrolling. If the $to
+position is after the EOF, $to will move to the end of the RecordSet for
+most databases. Some obscure databases using odbc might not behave this way.
    
+
+
    Note: This function uses absolute positioning, unlike Microsoft's
+ADO.
    
+
+
    Returns true or false. If false, the internal cursor is not moved in most
+implementations, so AbsolutePosition( ) will return the last cursor position
+before the Move( ). 
    
+
+
    MoveFirst()
    
+
+
    Internally calls Move(0). Note that some databases do not support this function.
    
+
+
    MoveLast()
    
+
+
    Internally calls Move(RecordCount()-1). Note that some databases do not
+support this function.
    
+
+
    GetRowAssoc($toUpper=true)
    
+
+
    Returns an associative array containing the current row. The keys to the
+array are the column names. The column names are upper-cased for easy access.
+To get the next row, you will still need to call MoveNext(). 
    
+
+
    For example:
    
+Array ( [ID] => 1 [FIRSTNAME] => Caroline [LASTNAME] => Miranda
+[CREATED] => 2001-07-05 ) 
    
+
+
    Note: do not use GetRowAssoc() with $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC.
+Because they have the same functionality, they will interfere with each other.
    
+
+
    AbsolutePage($page=-1) 
    
+
+
    Returns the current page. Requires PageExecute()/CachePageExecute() to be
+called. See Example 8.
    
+
+
    AtFirstPage($status='')
    
+
+
    Returns true if at first page (1-based). Requires
+PageExecute()/CachePageExecute() to be called. See Example 8.
    
+
+
    AtLastPage($status='')
    
+
+
    Returns true if at last page (1-based). Requires
+PageExecute()/CachePageExecute() to be called. See Example 8.
    
+
+
    Fields($colname)
    
+
+
    Returns the value of the associated column $colname for the current
+row. The column name is case-insensitive.
    
+
+
    This is a convenience function. For higher performance, use $ADODB_FETCH_MODE. 
    
+
+
    FetchRow()
    
+
+
    Returns array containing current row, or false if EOF. FetchRow( )
+internally moves to the next record after returning the current row. 
    
+
+
    Warning: Do not mix using FetchRow() with MoveNext().
    
+
+
    Usage:
    
+
+
    $rs = $db->Execute($sql);
    
+if ($rs)
    
+         while ($arr = $rs->FetchRow()) {
    
+              # process $arr       
    
+         }
    
+
+
    FetchInto(&$array)
    
+
+
    Sets $array to the current row. Returns PEAR_Error object if EOF, 1 if ok
+(DB_OK constant). If PEAR is undefined, false is returned when EOF. FetchInto(
+) internally moves to the next record after returning the current row. 
    
+
+
    FetchRow() is easier to use. See above.
    
+
+
    FetchField($column_number)
    
+
+
    Returns an object containing the name, type and max_length
+of the associated field. If the max_length cannot be determined reliably, it
+will be set to -1. The column numbers are zero-based. See example
+2.
    
+
+
    FieldCount( )
    
+
+
    Returns the number of fields (columns) in the record set.
    
+
+
    RecordCount( )
    
+
+
    Returns the number of rows in the record set. If the number of records
+returned cannot be determined from the database driver API, we will buffer all
+rows and return a count of the rows after all the records have been retrieved.
+This buffering can be disabled (for performance reasons) by setting the global
+variable $ADODB_COUNTRECS = false. When disabled, RecordCount( ) will return -1
+for certain databases. See the supported databases list above for more details.
+
    
+
+
    RowCount is a synonym for RecordCount.
    
+
+
    PO_RecordCount($table, $where)
    
+
+
    Returns the number of rows in the record set. If the database does not
+support this, it will perform a SELECT COUNT(*) on the table $table, with the
+given $where condition to return an estimate of the recordset size.
    
+
+
    $numrows = $rs->PO_RecordCount("articles_table",
+"group=$group");
    
+
+
    NextRecordSet()
+
    
+
+
    For databases that allow multiple recordsets to be returned in one query,
+this function allows you to switch to the next recordset. Currently only
+supported by mssql driver.
    
+
+
    $rs = $db->Execute('execute return_multiple_rs');
    
+$arr1 = $rs->GetArray();
    
+$rs->NextRecordSet();
    
+$arr2 = $rs->GetArray();
    
+
+
    FetchObject($toupper=true)
    
+
+
    Returns the current row as an object. If you set $toupper to true, then the
+object fields are set to upper-case. Note: The newer FetchNextObject() is the
+recommended way of accessing rows as objects. See below.
    
+
+
    FetchNextObject($toupper=true)
    
+
+
    Gets the current row as an object and moves to the next row automatically.
+Returns false if at end-of-file. If you set $toupper to true, then the object
+fields are set to upper-case. Note that for some drivers such as mssql, you
+need to SetFetchMode(ADODB_FETCH_ASSOC) or SetFetchMode(ADODB_FETCH_BOTH).
    
+
+
    $rs = $db->Execute('select firstname,lastname from table');
    
+if ($rs) {
    
+         while ($o = $rs->FetchNextObject()) {
    
+                 print "$o->FIRSTNAME, $o->LASTNAME<BR>";
    
+         }
    
+}
    
+
+
    There is some trade-off in speed in using FetchNextObject(). If performance
+is important, you should access rows with the fields[] array. FetchObj()
+
    
+
+
    Returns the current record as an object. Fields are not upper-cased, unlike
+FetchObject. 
    
+
+
    FetchNextObj() 
    
+
+
    Returns the current record as an object and moves to the next record. If
+EOF, false is returned. Fields are not upper-cased, unlike FetctNextObject. 
    
+
+
    CurrentRow( )
    
+
+
    Returns the current row of the record set. 0 is the first row.
    
+
+
    AbsolutePosition( )
    
+
+
    Synonym for CurrentRow for compatibility with ADO. Returns the
+current row of the record set. 0 is the first row.
    
+
+
    MetaType($nativeDBType[,$field_max_length],[$fieldobj])
    
+
+
    Determine what generic meta type a database field type is given its
+native type $nativeDBType as a string and the length of the field $field_max_length.
+Note that field_max_length can be -1 if it is not known. The field object
+returned by FetchField() can be passed in $fieldobj or as the 1st
+parameter $nativeDBType. This is useful for databases such as mysql
+which has additional properties in the field object such as primary_key.
+
    
+
+
    Uses the field blobSize and compares it with $field_max_length
+to determine whether the character field is actually a blob.
    
+
+
    For example, $db->MetaType('char') will return 'C'. 
    
+
+
    Returns:
    
+
+
      
+ 
    • C: Character fields
+     that should be shown in a <input type="text"> tag. 
      • 
+ 
    • X: Clob (character
+     large objects), or large text fields that should be shown in a
+     <textarea>
      • 
+ 
    • D: Date field
      • 
+ 
    • T: Timestamp field
      • 
+ 
    • L: Logical field
+     (boolean or bit-field)
      • 
+ 
    • N: Numeric field.
+     Includes decimal, numeric, floating point, and real. 
      • 
+ 
    • I:  Integer
+     field. 
      • 
+ 
    • R: Counter or
+     Autoincrement field. Must be numeric.
      • 
+ 
    • B: Blob, or binary
+     large objects. 
      • 
+
    
+
+
    Since ADOdb 3.0, MetaType accepts $fieldobj as the first parameter, instead
+of $nativeDBType. 
    
+
+
    Close( )
    
+
+
    Closes the recordset, cleaning all memory and resources associated with the
+recordset. 
    
+
+
    If memory management is not an issue, you do not need to call this function
+as recordsets are closed for you by PHP at the end of the script. SQL
+statements such as INSERT/UPDATE/DELETE do not really return a recordset, so you
+do not have to call Close() for such SQL statements.
    
+
+
    
+
+
    
+
+
    
+
+
    function rs2html($adorecordset,[$tableheader_attributes],
+[$col_titles])
    
+
+
    This is a standalone function (rs2html = recordset to html) that is similar
+to PHP's odbc_result_all function, it prints a ADORecordSet, $adorecordset
+as a HTML table. $tableheader_attributes allow you to control the table cellpadding,
+cellspacing and border attributes. Lastly you can replace the
+database column names with your own column titles with the array $col_titles.
+This is designed more as a quick debugging mechanism, not a production table
+recordset viewer.
    
+
+
    You will need to include the file tohtml.inc.php.
    
+
+
    Example of rs2html:
    
+
+
    <?
    
+include('tohtml.inc.php')    ; # load code common to ADOdb 
    
+include('adodb.inc.php'); # load code common to ADOdb 
    
+$conn = &ADONewConnection('mysql');   # create a connection 
    
+$conn->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
    
+$sql = 'select CustomerName, CustomerID from customers'; 
    
+$rs   = $conn->Execute($sql); 
    
+rs2html($rs,'border=2 cellpadding=3',array('Customer Name','Customer ID'));
    
+?>
    
+
+
    
+
+
    
+
+
    
+
+
    Differences between this ADOdb library and Microsoft ADO
    
+
+
      
+ 
    1. ADOdb only supports
+     recordsets created by a connection object. Recordsets cannot be created
+     independently.
      2. 
+ 
    2. ADO properties are implemented
+     as functions in ADOdb. This makes it easier to implement any enhanced ADO
+     functionality in the future.
      3. 
+ 
    3. ADOdb's ADORecordSet->Move() uses
+     absolute positioning, not relative. Bookmarks are not supported.
      4. 
+ 
    4. ADORecordSet->AbsolutePosition() cannot be used
+     to move the record cursor.
      5. 
+ 
    5. ADO Parameter objects are
+     not supported. Instead we have the ADOConnection::Parameter(
+     ) function, which provides a simpler interface for calling preparing
+     parameters and calling stored procedures.
      6. 
+ 
    6. Recordset properties for
+     paging records are available, but implemented as in Example
+     8.

    Database Driver Guide
    
+
+
    This describes how to create a class to connect to a new database. To ensure
+there is no duplication of work, kindly email me at jlim#natsoft.com if you
+decide to create such a class.
    
+
+
    First decide on a name in lower case to call the database type. Let's say we
+call it xbase. 
    
+
+
    Then we need to create two classes ADODB_xbase and ADORecordSet_xbase in the
+file adodb-xbase.inc.php.
    
+
+
    The simplest form of database driver is an adaptation of an existing ODBC
+driver. Then we just need to create the class ADODB_xbase extends ADODB_odbc
+to support the new date and timestamp formats, the concatenation
+operator used, true and false. For the ADORecordSet_xbase
+extends ADORecordSet_odbc we need to change the MetaType function.
+See adodb-vfp.inc.php as an example.
    
+
+
    More complicated is a totally new database driver that connects to a new PHP
+extension. Then you will need to implement several functions. Fortunately, you
+do not have to modify most of the complex code. You only need to override a few
+stub functions. See adodb-mysql.inc.php for example.
    
+
+
    The default date format of ADOdb internally is YYYY-MM-DD (Ansi-92). All
+dates should be converted to that format when passing to an ADOdb date
+function. See Oracle for an example how we use ALTER SESSION to change the
+default date format in _pconnect _connect.
    
+
+
    ADOConnection Functions to Override
    
+
+
    Defining a constructor for your ADOConnection derived function is optional.
+There is no need to call the base class constructor.
    
+
+
    _connect: Low level implementation of Connect. Returns true or false.
+Should set the _connectionID.
    
+
+
    _pconnect: Low level implemention of PConnect. Returns true or false.
+Should set the _connectionID.
    
+
+
    _query: Execute a query. Returns the queryID, or false.
    
+
+
    _close: Close the connection -- PHP should clean up all recordsets. 
    
+
+
    ErrorMsg: Stores the error message in the private variable _errorMsg.
+
    
+
+
    ADOConnection Fields to Set
    
+
+
    _bindInputArray: Set to true if binding of parameters for SQL inserts
+and updates is allowed using ?, eg. as with ODBC.
    
+
+
    fmtDate
    
+
+
    fmtTimeStamp
    
+
+
    true
    
+
+
    false
    
+
+
    concat_operator
    
+
+
    replaceQuote
    
+
+
    hasLimit support SELECT * FROM TABLE LIMIT 10 of MySQL.
    
+
+
    hasTop support Microsoft style SELECT TOP 10 * FROM TABLE.
    
+
+
    ADORecordSet Functions to Override
    
+
+
    You will need to define a constructor for your ADORecordSet derived class
+that calls the parent class constructor.
    
+
+
    FetchField: as documented above in ADORecordSet
    
+
+
    _initrs: low level initialization of the recordset: setup the _numOfRows
+and _numOfFields fields -- called by the constructor.
    
+
+
    _seek: seek to a particular row. Do not load the data into the fields
+array. This is done by _fetch. Returns true or false. Note that some
+implementations such as Interbase do not support seek. Set canSeek to false.
    
+
+
    _fetch: fetch a row using the database extension function and then
+move to the next row. Sets the fields array. If the parameter
+$ignore_fields is true then there is no need to populate the fields
+array, just move to the next row. then Returns true or false.
    
+
+
    _close: close the recordset
    
+
+
    Fields: If the array row returned by the PHP extension is not an
+associative one, you will have to override this. See adodb-odbc.inc.php for an
+example. For databases such as MySQL and MSSQL where an associative array is
+returned, there is no need to override this function.
    
+
+
    ADOConnection Fields to Set
    
+
+
    canSeek: Set to true if the _seek function works.

    Active Record: If you have a field which is a string field (with numbers in) and you add preceding 0's to it the adodb library does not pick up the fact that the field has changed because of the way php's == works (dodgily). The end result is that it never gets updated into the database - fix by  Matthew Forrester (MediaEquals). [matthew.forrester#mediaequals.com]
+
+
    Fixes RowLock() and MetaIndexes() inconsistencies. See http://phplens.com/lens/lensforum/msgs.php?id=18236

+
    +	# we have a memcache servers mem1,mem2 on port 8888, compression=off and cachesecs=120

    New API for creating your custom caching class which is stored in
+$ADODB_CACHE: 
    
+
+
     
    include "/path/to/adodb.inc.php";
    $ADODB_CACHE_CLASS = 'MyCacheClass';
     
    class MyCacheClass extends ADODB_Cache_File
    {
             function writecache($filename, $contents,$debug=false){...}
             function &readcache($filename, &$err, $secs2cache, $rsClass){ ...}
              :
    }
     
    $DB = NewADOConnection($driver);
    $DB->Connect(...);  ## MyCacheClass created here and stored in $ADODB_CACHE global variable.
     
    $data = $rs->CacheGetOne($sql); ## MyCacheClass is used here for caching...
    
+
+
    Memcache supports multiple pooled hosts now. Only if none of the pooled
+servers can be contacted will a connect error be generated. Usage example
+below: 
    
+
+
     
    $db = NewADOConnection($driver);
    $db->memCache = true; /// should we use memCache instead of caching in files
    $db->memCacheHost = array($ip1, $ip2, $ip3); /// $db->memCacheHost = $ip1; still works
    $db->memCachePort = 11211; /// this is default memCache port
    $db->memCacheCompress = false; /// Use 'true' to store the item compressed (uses zlib)
     
    $db->Connect(...);
    $db->CacheExecute($sql);

+
    Changed oci8 FetchField, which returns the max_length of BLOB/CLOB/NCLOB as
+4000 (incorrectly) to -1. 
    
+
+
    CacheExecute would sometimes return an error on Windows if it was unable to
+lock the cache file. This is harmless and has been changed to a warning that
+can be ignored. Also adodb_write_file() code revised. 
    
+
+
    ADOdb perf code changed to only log sql if execution time >= 0.05
+seconds. New $ADODB_PERF_MIN variable holds min sql timing. Any SQL with timing
+value below this and is not causing an error is not logged. 
    
+
+
    Also adodb_backtrace() now traces 1 level deeper as sometimes actual culprit
+function is not displayed.

+
    Fixed a group by problem with adodb_getcount() for db's which are not
+postgres/oci8 based. 
    
+

    4.96/5.02 24 Sept 2007 
    
+
+
    ADOdb perf for oci8 now has non-table-locking code when clearing the sql.
+Slower but better transparency. Added in 4.96a and 5.02a. 
    
+
+
    Fix adodb count optimisation. Preg_match did not work properly. Also rewrote
+the ORDER BY stripping code in _adodb_getcount(), adodb-lib.inc.php. 
    
+
+
    SelectLimit for oci8 not optimal for large recordsets when offset=0. Changed
+$nrows check. 
    
+
+
    Active record optimizations. Added support for assoc arrays in Set(). 
    
+
+
    Now GetOne returns null if EOF (no records found), and false if error
+occurs. Use ErrorMsg()/ErrorNo() to get the error. 
    
+
+
    Also CacheGetRow and CacheGetCol will return false if error occurs, or empty
+array() if EOF, just like GetRow and GetCol. 
    
+
+
    Datadict now allows changing of types which are not resizable, eg. VARCHAR
+to TEXT in ChangeTableSQL. -- Mateo Tibaquirá

    Also in adodb5, changed adodb-session2 to use static function declarations
+in class. Thx Daniel Berlin.
+
    
+
+
    Added "Clear SQL Log" to bottom of Performance screen. 
    
+
+
    Sessions2 code echo'ed directly to the screen in debug mode. Now uses
+ADOConnection::outp(). 
    
+
+
    In mysql/mysqli, qstr(null) will return the string "null" instead
+of empty quoted string "''". 
    
+
+
    postgresql optimizeTable in perf-postgres.inc.php added by Daniel Berlin
+(mail#daniel-berlin.de) 
    
+

+Stefano Nari. 
    
+
+
    Code sanitization introduced in 4.95 caused problems in European locales (as

+and Marcos Pont
    
+
+
    Added zerofill checking support to MetaColumns for mysql and mysqli. 
    
+
+
    CacheFlush no longer deletes all files/directories. Only *.cache files
+deleted.
    
+
+
    DB2 timestamp format changed to var $fmtTimeStamp =
+"'Y-m-d-H:i:s'";
    
+
+
    Added some code sanitization to AutoExecute in adodb-lib.inc.php.
    
+
+
    Due to typo, all connections in adodb-oracle.inc.php would become
+persistent, even non-persistent ones. Fixed.
    
+
+
    Oci8 DBTimeStamp uses 24 hour time for input now, so you can perform string
+comparisons between 2 DBTimeStamp values.
    
+
+
    Some PHP4.4 compat issues fixed in adodb-session2.inc.php
    
+
+
    For ADOdb 5.01, fixed some adodb-datadict.inc.php MetaType compat issues

++ Prevents the generated SQL from including double drop-sequence statements for
+REPLACE case of tables with autoincrement columns (on those dbs that emulate it
+via sequences) 
    
++ makes any date defined as DEFAULT value for D and T columns work
+cross-database, not just the "sysdate" value (as long as it is
+specified using adodb standard format). See above example. 
    
+

    $db->memCacheHost = "126.0.1.1"; /// memCache host
    $db->memCachePort = 11211; /// this is default memCache port
    $db->memCacheCompress = false; /// Use 'true' to store the item compressed (uses zlib)
     
    $db->Connect(...);
    $db->CacheExecute($sql);
    
+
+
    Implemented Transpose() for recordsets. Recordset must be retrieved using
+ADODB_FETCH_NUM. First column becomes the column name. 
    
+
+
     
    $DB = NewADOConnection('mysql');
    $DB->Connect(...);
    $DB->SetFetchMode(ADODB_FETCH_NUM);
    $rs = $DB->Execute('select productname,productid,unitprice from products limit 10');

    Added INET to postgresql metatypes. Thx motzel. 
    
+
+
    Allow oracle hints to work when counting with _adodb_getcount in
+adodb-lib.inc.php. Thx Chris Wrye. 
    
+
+
    Changed mysql insert_id() to use SELECT LAST_INSERT_ID(). 
    
+
+
    If alter col in datadict does not modify col type/size of actual col, then
+it is removed from alter col code. By Mark Newham. Not perfect as MetaType()
+!== ActualType(). 
    
+
+
    Added handling of view fields in metacolumns() for postgresql. Thx Renato De
+Giovanni. 
    
+
+
    Added to informix MetaPrimaryKeys and MetaColumns fixes for null bit. Thx to
+Cecilio Albero. 
    
+
+
    Removed obsolete connection_timeout() from perf code. 
    
+
+
    Added support for arrayClass in adodb-csv.inc.php. 
    
+
+
    RSFilter now accepts methods of the form $array($obj, 'methodname'). Thx to
+blake#near-time.com. 
    
+
+
    Changed CacheFlush to $cmd = 'rm -rf
+'.$ADODB_CACHE_DIR.'/[0-9a-f][0-9a-f]/'; 
    
+
+
    For better cursor concurrency, added code to free ref cursors in oci8 when
+$rs->Close() is called. Note that CLose() is called internally by the Get*
+functions too. 
    
+
+
    Added IIF support for access when pivoting. Thx Volodia Krupach. 
    
+
+
    Added mssql datadict support for timestamp. Thx Alexios. 
    
+
+
    Informix pager fix. By Mario Ramirez. 
    
+
+
    ADODB_TABLE_REGEX now includes ':'. By Mario Ramirez. 
    
+
+
    Mark Newnham contributed MetaIndexes for oci8 and db2. 
    
+
+
    4.54 5 Nov 2004 
    
+
+
    Now you can set $db->charSet = ?? before doing a Connect() in oci8. 
    
+
+
    Added adodbFetchMode to sqlite. 
    
+
+
    Perf code, added a string typecast to substr in adodb_log_sql(). 
    
+
+
    Postgres: Changed BlobDecode() to use po_loread, added new $maxblobsize
+parameter, and now it returns the blob instead of sending it to stdout - make
+sure to mention that as a compat warning. Also added $db->IsOID($oid)
+function; uses a heuristic, not guaranteed to work 100%. 
    
+
+
    Contributed arabic language file by "El-Shamaa, Khaled"
+k.el-shamaa#cgiar.org 
    
+
+
    PHP5 exceptions did not handle @ protocol properly. Fixed. 
    
+
+
    Added ifnull handling for postgresql (using coalesce). 
    
+
+
    Added metatables() support for Postgresql 8.0 (no longer uses pg_%
+dictionary tables). 
    
+
+
    Improved Sybase ErrorMsg() function. By Gaetano Giunta. 
    
+
+
    Improved oci8 SelectLimit() to use Prepare(). By Cristiano Duarte. 
    
+
+
    Type-cast $row parameter in ifx_fetch_row() to int. Thx stefan bodgan. 
    
+
+
    Ralf becker contributed improvements in postgresql, sapdb, mysql data
+dictionary handling:
    
+- MySql and Postgres MetaType was reporting every int column which was part of
+a primary key and unique as serial
    
+- Postgres was not reporting the scale of decimal types
    
+- MaxDB was padding the defaults of none-string types with spaces
    
+- MySql now correctly converts enum columns to varchar 
    
+
+
    Ralf also changed Postgresql datadict:
    
+- you cant add NOT NULL columns in postgres in one go, they need to be added as
+NULL and then altered to NOT NULL
    
+- AlterColumnSQL could not change a varchar column with numbers into an integer
+column, postgres need an explicit conversation
    
+- a re-created sequence was not set to the correct value, if the name was the
+old name (no implicit sequence), now always the new name of the implicit
+sequence is used
    
+
+
    Sergio Strampelli added extra $intoken check to Lens_ParseArgs() in datadict
+code. 
    
+
+
    4.53 28 Sept 2004 
    
+
+
    FetchMode cached in recordset is sometimes mapped to native db fetchMode.
+Normally this does not matter, but when using cached recordsets, we need to
+switch back to using adodb fetchmode. So we cache this in
+$rs->adodbFetchMode if it differs from the db's fetchMode. 
    
+
+
    For informix we now set canSeek = false driver because stefan bodgan tells
+me that seeking doesn't work. 
    
+
+
    SetDateLocale() never worked till now ;-) Thx david#tomato.it 
    
+
+
    Set $_bindInputArray = true in sapdb driver. Required for clob support. 
    
+
+
    Fixed some PEAR::DB emulation issues with isError() and isWarning. Thx to
+Gert-Rainer Bitterlich. 
    
+
+
    Empty() used in getupdatesql without strlen() check. Fixed.
    
+
+
    Added unsigned detection to mysql and mysqli drivers. Thx to dan cech. 
    
+
+
    Added hungarian language file. Thx to Halászvári Gábor. 
    
+
+
    Improved fieldname-type formatting of datadict SQL generated (adding
+$widespacing parameter to _GenField). 
    
+
+
    Datadict oci8 DROP CONSTRAINTS misspelt. Fixed. Thx Mark Newnham. 
    
+
+
    Changed odbtp to dynamically change databaseType based on connection, eg.
+from 'odbtp' to 'odbtp_mssql' when connecting to mssql database. 
    
+
+
    In datadict, MySQL I4 was wrongly mapped to MEDIUMINT, which is actually I3.
+Fixed. 
    
+
+
    Fixed mysqli MetaType() recognition. Mysqli returns numeric types unlike
+mysql extension. Thx Francesco Riosa. 
    
+
+
    VFP odbc driver curmode set wrongly, causing problems with memo fields.
+Fixed. 
    
+
+
    Odbc driver did not recognize odbc version 2 driver date types properly.
+Fixed. Thx Bostjan. 
    
+
+
    ChangeTableSQL() fixes to datadict-db2.inc.php by Mark Newnham. 
    
+
+
    Perf monitoring with odbc improved. Now we try in perf code to manually set
+the sysTimeStamp using date() if sysTimeStamp is empty. 
    
+
+
    All ADO
+errors are thrown as exceptions in PHP5. So we added exception handling to ado
+in PHP5 by creating new adodb-ado5.inc.php driver. 
    
+
+
    Added IsConnected(). Returns true if connection object connected. By
+Luca.Gioppo. 
    
+
+
    "Ralf Becker" RalfBecker#digitalROCK.de contributed new sapdb
+data-dictionary driver and a large patch that implements field and table
+renaming for oracle, mssql, postgresql, mysql and sapdb. See the new RenameTableSQL()
+and RenameColumnSQL() functions. 
    
+
+
    We now check ExecuteCursor to see if PrepareSP was initially called. 
    
+
+
    Changed oci8 datadict to use MODIFY for $dd->alterCol. Thx Mark Newnham. 
    
+
+
    4.52 10 Aug 2004 
    
+
+
    Bug found in Replace() when performance logging enabled, introduced in ADOdb
+4.50. Fixed. 
    
+
+
    Replace() checks update stmt. If update stmt fails, we now return
+immediately. Thx to alex. 
    
+
+
    Added support for $ADODB_FORCE_TYPE in GetUpdateSQL/GetInsertSQL. Thx to
+niko. 
    
+
+
    Added ADODB_ASSOC_CASE support to postgres/postgres7 driver. 
    
+
+
    Support for DECLARE stmt in oci8. Thx Lochbrunner. 
    
+
+
    4.51 29 July 2004 
    
+
+
    Added adodb-xmlschema 1.0.2. Thx dan and richard. 
    
+
+
    Added new adorecordset_ext_* classes. If ADOdb extension installed for
+mysql, mysqlt and oci8 (but not oci8po), we use the superfast ADOdb extension
+code for movenext. 
    
+
+
    Added schema support to mssql and odbc_mssql MetaPrimaryKeys(). 
    
+
+
    Patched MSSQL driver to support PHP NULL and Boolean values while binding
+the input array parameters in the _query() function. By Stephen Farmer. 
    
+
+
    Added support for clob's for mssql, UpdateBlob(). Thx to
+gfran#directa.com.br 
    
+
+
    Added normalize support for postgresql (true=lowercase table name, or
+false=case-sensitive table names) to MetaColumns($table, $normalize=true). 
    
+
+
    PHP5 variant dates in ADO
+not working. Fixed in adodb-ado.inc.php. 
    
+
+
    Constant ADODB_FORCE_NULLS was not working properly for many releases (for
+GetUpdateSQL). Fixed. Also GetUpdateSQL strips off ORDER BY now - thx Elieser
+Leão. 
    
+
+
    Perf Monitor for oci8 now dynamically highlights optimizer_* params if too
+high/low. 
    
+
+
    Added dsn support to NewADOConnection/ADONewConnection. 
    
+
+
    Fixed out of page bounds bug in _adodb_pageexecute_all_rows() Thx to
+"Sergio Strampelli" sergio#rir.it 
    
+
+
    Speedup of movenext for mysql and oci8 drivers. 
    
+
+
    Moved debugging code _adodb_debug_execute() to adodb-lib.inc.php. 
    
+
+
    Fixed postgresql bytea detection bug. See
+http://phplens.com/lens/lensforum/msgs.php?id=9849. 
    
+
+
    Fixed ibase datetimestamp typo in PHP5. Thx stefan. 
    
+
+
    Removed whitespace at end of odbtp drivers. 
    
+
+
    Added db2 metaprimarykeys fix. 
    
+
+
    Optimizations to MoveNext() for mysql and oci8. Misc speedups to Get*
+functions. 
    
+
+
    4.50 6 July 2004 
    
+
+
    Bumped it to 4.50 to avoid confusion with PHP 4.3.x series. 
    
+
+
    Added db2 metatables and metacolumns extensions. 
    
+
+
    Added alpha PDO driver. Very buggy, only works with odbc. 
    
+
+
    Tested mysqli. Set poorAffectedRows = true. Cleaned up movenext() and
+_fetch(). 
    
+
+
    PageExecute does not work properly with php5 (return val not a variable).
+Reported Dmytro Sychevsky sych#php.com.ua. Fixed. 
    
+
+
    MetaTables() for mysql, $showschema parameter was not backward compatible
+with older versions of adodb. Fixed. 
    
+
+
    Changed mysql GetOne() to work with mysql 3.23 when using with non-select
+stmts (e.g. SHOW TABLES). 
    
+
+
    Changed TRIG_ prefix to a variable in datadict-oci8.inc.php. Thx to
+Luca.Gioppo#csi.it. 
    
+
+
    New to adodb-time code. We allow you to define your own daylights savings
+function, adodb_daylight_sv for pre-1970 dates. If the function is defined
+(somewhere in an include), then you can correct for daylights savings. See
+http://phplens.com/phpeverywhere/node/view/16#daylightsavings for more info. 
    
+
+
    New sqlitepo driver. This is because assoc mode does not work like other
+drivers in sqlite. Namely, when selecting (joining) multiple tables, in assoc
+mode the table names are included in the assoc keys in the "sqlite"
+driver. In "sqlitepo" driver, the table names are stripped from the
+returned column names. When this results in a conflict, the first field get
+preference. Contributed by Herman Kuiper herman#ozuzo.net 
    
+
+
    Added $forcenull parameter to GetInsertSQL/GetUpdateSQL. Idea by Marco
+Aurelio Silva. 
    
+
+
    More XHTML changes for GetMenu. By Jeremy Evans. 
    
+
+
    Fixes some ibase date issues. Thx to stefan bogdan. 
    
+
+
    Improvements to mysqli driver to support $ADODB_COUNTRECS. 
    
+
+
    Fixed adodb-csvlib.inc.php problem when reading stream from socket. We need
+to poll stream continiously. 
    
+
+
    4.23 16 June 2004 
    
+
+
    New interbase/firebird fixes thx to Lester Caine. Driver fixes a problem
+with getting field names in the result array, and corrects a couple of data
+conversions. Also we default to dialect3 for firebird. Also ibase sysDate
+property was wrong. Changed to cast as timestamp. 
    
+
+
    The datadict driver is set up to give quoted tables and fields as this was
+the only way round reserved words being used as field names in TikiWiki.
+TikiPro is tidying that up, and I hope to be able to produce a build of THAT
+which uses what I consider proper UPPERCASE field and table names. The
+conversion of TikiWiki to ADOdb helped in that, but until the database is
+completely tidied up in TikiPro ... 
    
+
+
    Modified _gencachename() to include fetchmode in name hash. This means you
+should clear your cache directory after installing this release as the cache
+name algorithm has changed. 
    
+
+
    Now Cache* functions work in safe mode, because we do not create
+sub-directories in the $ADODB_CACHE_DIR in safe mode. In non-safe mode we still
+create sub-directories. Done by modifying _gencachename(). 
    
+
+
    Added $gmt parameter (true/false) to UserDate and UserTimeStamp in
+connection class, to force conversion of input (in local time) to be converted
+to UTC/GMT. 
    
+
+
    Mssql datadict did not support INT types properly (no size param allowed).
+Added _GetSize() to datadict-mssql.inc.php. 
    
+
+
    For borland_ibase, BeginTrans(), changed:
    
+
+
       $this->_transactionID = $this->_connectionID;
    
+
+
    to
    
+
+
       $this->_transactionID = ibase_trans($this->ibasetrans, $this->_connectionID);
    
+
+
    Fixed typo in mysqi_field_seek(). Thx to Sh4dow (sh4dow#php.pl). 
    
+
+
    LogSQL did not work with Firebird/Interbase. Fixed. 
    
+
+
    Postgres: made errorno() handling more consistent. Thx to Michael Jahn,
+Michael.Jahn#mailbox.tu-dresden.de. 
    
+
+
    Added informix patch to better support metatables, metacolumns by
+"Cecilio Albero" c-albero#eos-i.com 
    
+
+
    Cyril Malevanov contributed patch to oci8 to support passing of LOB
+parameters: 
    
+
+
             $text = 'test test test';
    
+         $sql = "declare rs clob; begin :rs := lobinout(:sa0); end;";
    
+         $stmt = $conn -> PrepareSP($sql);
    
+         $conn -> InParameter($stmt,$text,'sa0', -1, OCI_B_CLOB);
    
+         $rs = '';
    
+         $conn -> OutParameter($stmt,$rs,'rs', -1, OCI_B_CLOB);
    
+         $conn -> Execute($stmt);
    
+         echo "return = ".$rs."<br>";
    
+
+
    As he says, the LOBs limitations are: 
    
+
+
     - use OCINewDescriptor before binding
    
+ - if Param is IN, uses save() before each execute. This is done automatically for you.
    
+ - if Param is OUT, uses load() after each execute. This is done automatically for you.
    
+ - when we bind $var as LOB, we create new descriptor and return it as a
    
+   Bind Result, so if we want to use OUT parameters, we have to store
    
+   somewhere &$var to load() data from LOB to it.
    
+ - IN OUT params are not working now (should not be a big problem to fix it)
    
+ - now mass binding not working too (I've wrote about it before)
    
+
+
    Simplified Connect() and PConnect() error handling. 
    
+
+
    When extension not loaded, Connect() and PConnect() will return null. On
+connect error, the fns will return false. 
    
+
+
    CacheGetArray() added to code. 
    
+
+
    Added Init() to adorecordset_empty(). 
    
+
+
    Changed postgres64 driver, MetaColumns() to not strip off quotes in default
+value if :: detected (type-casting of default). 
    
+
+
    Added test: if (!defined('ADODB_DIR')) die(). Useful to prevent hackers from
+detecting file paths. 
    
+
+
    Changed metaTablesSQL to ignore Postgres 7.4 information schemas (sql_*). 
    
+
+
    New polish language file by Grzegorz Pacan 
    
+
+
    Added support for UNION in
+_adodb_getcount(). 
    
+
+
    Added security check for ADODB_DIR to limit path disclosure issues.
+Requested by postnuke team. 
    
+
+
    Added better error message support to oracle driver. Thx to Gaetano Giunta. 
    
+
+
    Added showSchema support to mysql. 
    
+
+
    Bind in oci8 did not handle $name=false properly. Fixed. 
    
+
+
    If extension not loaded, Connect(), PConnect(), NConnect() will return null.
+
    
+
+
    4.22 15 Apr 2004 
    
+
+
    Moved docs to own adodb/docs folder. 
    
+
+
    Fixed session bug when quoting compressed/encrypted data in Replace(). 
    
+
+
    Netezza Driver and LDAP drivers contributed by Josh Eldridge. 
    
+
+
    GetMenu now uses rtrim() on values instead of trim(). 
    
+
+
    Changed MetaColumnNames to return an associative array, keys being the field
+names in uppercase. 
    
+
+
    Suggested fix to adodb-ado.inc.php affected_rows to support PHP5 variants.
+Thx to Alexios Fakos.

    GetInsertSQL now checks for table name (string) in $rs, and will create a
+recordset for that table automatically. Contributed by Walt Boring. Also added
+OCI_B_BLOB in bind on Walt's request - hope it doesn't break anything :-) 
    
+
+
    Some minor postgres speedups in _initrs(). 
    
+
+
    ChangeTableSQL checks now if MetaColumns returns empty. Thx Jason Judge. 
    
+
+
    Added ADOConnection::Time(), returns current database time in unix timestamp
+format, or false. 
    
+
+
    4.21 20 Mar 2004 
    
+
+
    We no longer in SelectLimit for VFP driver add SELECT TOP X unless an ORDER
+BY exists. 
    
+
+
    Pim Koeman contributed dutch language file adodb-nl.inc.php. 
    
+
+
    Rick Hickerson added CLOB support to db2 datadict. 
    
+
+
    Added odbtp driver. Thx to "stefan bogdan" sbogdan#rsb.ro. 
    
+
+
    Changed PrepareSP() 2nd parameter, $cursor, to default to true (formerly
+false). Fixes oci8 backward compat problems with OUT params. 
    
+
+
    Fixed month calculation error in adodb-time.inc.php. 2102-June-01 appeared
+as 2102-May-32. 
    
+
+
    Updated PHP5 RC1 iterator support. API changed, hasMore() renamed to
+valid(). 
    
+
+
    Changed internal format of serialized cache recordsets. As we store a
+version number, this should be backward compatible. 
    
+
+
    Error handling when driver file not found was flawed in ADOLoadCode().
+Fixed. 
    
+
+
    4.20 27 Feb 2004 
    
+

    Updated to AXMLS 1.01. 
    
+
+
    MetaForeignKeys for postgres7 modified by Edward Jaramilla, works on pg 7.4.
+
    
+
+
    Now numbers accepts function calls or sequences for
+GetInsertSQL/GetUpdateSQL numeric fields. 
    
+
+
    Changed quotes of 'delete from $perf_table' to "". Thx Kehui
+(webmaster#kehui.net) 
    
+
+
    Added ServerInfo() for ifx, and putenv trim fix. Thx Fernando Ortiz. 
    
+
+
    Added addq(), which is analogous to addslashes(). 
    
+
+
    Tested with php5b4. Fix some php5 compat problems with exceptions and
+sybase. 
    
+
+
    Carl-Christian Salvesen added patch to mssql _query to support binds greater
+than 4000 chars. 
    
+
+
    Mike suggested patch to PHP5 exception handler. $errno must be numeric. 
    
+
+
    Added double quotes (") to ADODB_TABLE_REGEX. 
    
+
+
    For oci8, Prepare(...,$cursor), $cursor's meaning was accidentally inverted
+in 4.11. This causes problems with ExecuteCursor() too, which calls Prepare()
+internally. Thx to William Lovaton. 
    
+
+
    Now dateHasTime property in connection object renamed to datetime for
+consistency. This could break bc. 
    
+

+
+
    Dan Cech modifies datadict code. Adds support for DropIndex. Minor cleanups.

+
    Table misspelt in perf-oci8.inc.php. Changed v$conn_cache_advice to
+v$db_cache_advice. Reported by Steve W. 
    
+
+
    UserTimeStamp and DBTimeStamp did not handle YYYYMMDDHHMMSS format properly.
+Reported by Mike Muir. Fixed. 
    
+
+
    Changed oci8 Prepare(). Does not auto-allocate OCINewCursor automatically,
+unless 2nd param is set to true. This will break backward compat, if
+Prepare/Execute is used instead of ExecuteCursor. Reported by Chris Jones. 
    
+
+
    Added InParameter() and OutParameter(). Wrapper functions to Parameter(),
+but nicer because they are self-documenting. 
    
+
+
    Added 'R' handling in ActualType() to datadict-mysql.inc.php 
    
+
+
    Added ADOConnection::SerializableRS($rs). Returns a recordset that can be

+multiple connections. 
    
+
+
    Added SQLDate support for sybase. Thx to Chris Phillipson

+  ADOdb Data Dictionary Manual

+  
+
+
+
    ADOdb Data Dictionary Library for PHP
    
+
    V5.06 16 Oct 2008  (c) 2000-2010 John Lim (jlim#natsoft.com).
    
+AXMLS (c) 2004 ars Cognita, Inc
    
+
    This software is dual licensed using BSD-Style and
+LGPL. This means you can use it in compiled proprietary and commercial
+products.
    
+
+
    Useful ADOdb links: Download
+  Other Docs
+
    
+
    This documentation describes a PHP class library to automate the
+creation of tables, indexes and foreign key constraints portably for
+multiple databases. Richard Tango-Lowy and Dan Cech have been kind
+enough to contribute AXMLS, an XML schema
+system for defining databases. You can contact them at
+dcech#phpwerx.net and richtl#arscognita.com.
    
+
    Currently the following databases are supported:
    
+
     Well-tested: PostgreSQL, MySQL, Oracle, MSSQL.
    
+Beta-quality: DB2, Informix, Sybase, Interbase, Firebird, SQLite.
    
+Alpha-quality: MS Access (does not support DEFAULT values) and
+generic ODBC.
+
    
+
    Example Usage
    
+
      include_once('adodb.inc.php');
      # First create a normal connection
      $db = NewADOConnection('mysql');
      $db->Connect(...);

      # Then create a data dictionary object, using this connection
      $dict = NewDataDictionary($db);

      # We have a portable declarative data dictionary format in ADOdb, similar to SQL.
      # Field types use 1 character codes, and fields are separated by commas.
      # The following example creates three fields: "col1", "col2" and "col3":
      $flds = " 
       col1 C(32) NOTNULL DEFAULT 'abc',
       col2 I  DEFAULT 0,
       col3 N(12.2)
      ";

      # We demonstrate creating tables and indexes
      $sqlarray = $dict->CreateTableSQL($tabname, $flds, $taboptarray);
      $dict->ExecuteSQLArray($sqlarray);

      $idxflds = 'co11, col2';
      $sqlarray = $dict->CreateIndexSQL($idxname, $tabname, $idxflds);
      $dict->ExecuteSQLArray($sqlarray);
    
+
    More Complex Table Sample
    
+
    
+The following string will create a table with a primary key event_id and multiple indexes, including one compound index idx_ev1. The ability to define indexes using the INDEX keyword was added in ADOdb 4.94 by Gaetano Giunta.
+
    +$flds = "
+  event_id I(11) NOTNULL AUTOINCREMENT PRIMARY,
+  event_type I(4) NOTNULL  INDEX idx_evt,
+  event_start_date T DEFAULT NULL INDEX id_esd,
+  event_end_date T DEFAULT '0000-00-00 00:00:00' INDEX id_eted,
+  event_parent I(11) UNSIGNED NOTNULL DEFAULT 0 INDEX id_evp,
+  event_owner I(11) DEFAULT 0 INDEX idx_ev1,
+  event_project I(11) DEFAULT 0 INDEX idx_ev1,
+  event_times_recuring I(11) UNSIGNED NOTNULL DEFAULT 0,
+  event_icon C(20) DEFAULT 'obj/event',
+  event_description X
+";
+$sqlarray = $db->CreateTableSQL($tablename, $flds);
+$dict->ExecuteSQLArray($sqlarray);
+
    
+
    Class Factory
    
+
    NewDataDictionary($connection, $drivername=false)
    
+
    Creates a new data dictionary object. You pass a database connection object in $connection. The $connection does not have to be actually connected to the database. Some database connection objects are generic (eg. odbtp and odbc). Since 4.53, you can tell ADOdb  the actual database with $drivername. E.g.
    
+
    +$db = NewADOConnection('odbtp');
+$datadict = NewDataDictionary($db, 'mssql'); # force mssql
+
    
+
    Class Functions
    
+
    function CreateDatabase($dbname, $optionsarray=false)
    
+
    Create a database with the name $dbname;
    
+
    function CreateTableSQL($tabname, $fldarray, $taboptarray=false)
    
+
      RETURNS:      an array of strings, the sql to be executed, or false
      $tabname:     name of table
      $fldarray:    string (or array) containing field info
      $taboptarray: array containing table options
    
+
    The new format of $fldarray uses a free text format, where each
+field is comma-delimited.
+The first token for each field is the field name, followed by the type
+and optional
+field size. Then optional keywords in $otheroptions:
    
+
      "$fieldname $type $colsize $otheroptions"
    
+
    The older (and still supported) format of $fldarray is a
+2-dimensional array, where each row in the 1st dimension represents one
+field. Each row has this format:
    
+
      array($fieldname, $type, [,$colsize] [,$otheroptions]*)
    
+
    The first 2 fields must be the field name and the field type. The
+field type can be a portable type codes or the actual type for that
+database.
    
+
    Legal portable type codes include:
    
+
      C:  Varchar, capped to 255 characters.
      X:  Larger varchar, capped to 4000 characters (to be compatible with Oracle). 
      XL: For Oracle, returns CLOB, otherwise the largest varchar size.

      C2: Multibyte varchar
      X2: Multibyte varchar (largest size)

      B:  BLOB (binary large object)

      D:  Date (some databases do not support this, and we return a datetime type)
      T:  Datetime or Timestamp accurate to the second.
      TS: Datetime or Timestamp supporting Sub-second accuracy.
           Supported by Oracle, PostgreSQL and SQL Server currently. 
           Otherwise equivalent to T.
    
+  L:  Integer field suitable for storing booleans (0 or 1)
      I:  Integer (mapped to I4)
      I1: 1-byte integer
      I2: 2-byte integer
      I4: 4-byte integer
      I8: 8-byte integer
      F:  Floating point number
      N:  Numeric or decimal number
    
+
    The $colsize field represents the size of the field. If a decimal
+number is used, then it is assumed that the number following the dot is
+the precision, so 6.2 means a number of size 6 digits and 2 decimal
+places. It is recommended that the default for number types be
+represented as a string to avoid any rounding errors.
    
+
    The $otheroptions include the following keywords (case-insensitive):
    
+
      AUTO            For autoincrement number. Emulated with triggers if not available.
                      Sets NOTNULL also.
      AUTOINCREMENT   Same as auto.
      KEY             Primary key field. Sets NOTNULL also. Compound keys are supported.
      PRIMARY         Same as KEY.
      DEF             Synonym for DEFAULT for lazy typists.
      DEFAULT         The default value. Character strings are auto-quoted unless
                      the string begins and ends with spaces, eg ' SYSDATE '.
      NOTNULL         If field is not null.
      DEFDATE         Set default value to call function to get today's date.
      DEFTIMESTAMP    Set default to call function to get today's datetime.
      NOQUOTE         Prevents autoquoting of default string values.
      CONSTRAINTS     Additional constraints defined at the end of the field
                      definition.
    
+
    The Data Dictonary accepts two formats, the older array
+specification:
    
+
      $flds = array(
        array('COLNAME',   'DECIMAL', '8.4', 'DEFAULT' =gt; 0, 'NOTNULL'),
        array('id',        'I'      , 'AUTO'),
        array('`MY DATE`', 'D'      , 'DEFDATE'),
        array('NAME',      'C'      , '32', 'CONSTRAINTS' =gt; 'FOREIGN KEY REFERENCES reftable')
      );
    
+
    Or the simpler declarative format:
    
+
      $flds = "
        COLNAME DECIMAL(8.4) DEFAULT 0 NOTNULL,
        id I AUTO,
        `MY DATE` D DEFDATE,
        NAME C(32) CONSTRAINTS 'FOREIGN KEY REFERENCES reftable'
      ";
    
+
    Note that if you have special characters in the field name (e.g. My
+Date), you should enclose it in back-quotes. Normally field names are
+not case-sensitive, but if you enclose it in back-quotes, some
+databases will treat the names as case-sensitive (eg. Oracle) , and
+others won't. So be careful.
    
+
    The $taboptarray is the 3rd parameter of the CreateTableSQL
+function. This contains table specific settings. Legal keywords include:
    
+
      
+  
    • REPLACE
      
+Indicates that the previous table definition should be removed
+(dropped)together with ALL data. See first example below. 
      • 
+  
    • DROP
      
+Drop table. Useful for removing unused tables. 
      • 
+  
    • CONSTRAINTS
      
+Define this as the key, with the constraint as the value. See the
+postgresql example below. Additional constraints defined for the whole
+table. You will probably need to prefix this with a comma. 
      • 
+
    
+
    Database specific table options can be defined also using the name
+of the database type as the array key. In the following example, create
+the table as ISAM with MySQL, and store the table in the "users"
+tablespace if using Oracle. And because we specified REPLACE, drop
+the table first.
    
+
      $taboptarray = array('mysql' =gt; 'TYPE=ISAM', 'oci8' =gt; 'tablespace users', 'REPLACE');
    
+
    You can also define foreign key constraints. The following is syntax
+for postgresql:
+
    
+
      $taboptarray = array('constraints' =gt; ', FOREIGN KEY (col1) REFERENCES reftable (refcol)');
    
+
    function DropTableSQL($tabname)
    
+
    Returns the SQL to drop the specified table.
    
+
    function ChangeTableSQL($tabname, $flds, $tableOptions=false, $dropOldFlds=false)
    
+
    Checks to see if table exists, if table does not exist, behaves like
+CreateTableSQL. If table exists, generates appropriate ALTER TABLE
+MODIFY COLUMN commands if field already exists, or ALTER TABLE ADD
+$column if field does not exist.
    
+
    The class must be connected to the database for ChangeTableSQL to
+detect the existence of the table. Idea and code contributed by Florian
+Buzin.
    
+
    Old fields not defined in $flds are not dropped by default. To drop old fields, set $dropOldFlds to true.
+
    function RenameTableSQL($tabname,$newname)
    
+
    Rename a table.  Returns the an array of strings, which is the SQL required to rename a table. Since ADOdb 4.53. Contributed by Ralf Becker.
    
+
     function RenameColumnSQL($tabname,$oldcolumn,$newcolumn,$flds='')
    
+
    Rename a table field. Returns the an array of strings, which is the SQL required to rename a column. The optional $flds is a complete column-defintion-string like for AddColumnSQL, only used by mysql at the moment. Since ADOdb 4.53. Contributed by Ralf Becker.
    
+
    function CreateIndexSQL($idxname, $tabname, $flds,
+$idxoptarray=false)
    
+
      RETURNS:      an array of strings, the sql to be executed, or false
      $idxname:     name of index
      $tabname:     name of table
      $flds:        list of fields as a comma delimited string or an array of strings
      $idxoptarray: array of index creation options
    
+
    $idxoptarray is similar to $taboptarray in that index specific
+information can be embedded in the array. Other options include:
    
+
      CLUSTERED     Create clustered index (only mssql)
      BITMAP        Create bitmap index (only oci8)
      UNIQUE        Make unique index
      FULLTEXT      Make fulltext index (only mysql)
      HASH          Create hash index (only postgres)
      DROP          Drop legacy index
    
+
    function DropIndexSQL ($idxname, $tabname = NULL)
    
+
    Returns the SQL to drop the specified index.
    
+
    function AddColumnSQL($tabname, $flds)
    
+
    Add one or more columns. Not guaranteed to work under all situations.
    
+
    function AlterColumnSQL($tabname, $flds)
    
+
    Warning, not all databases support this feature.
    
+
    function DropColumnSQL($tabname, $flds)
    
+
    Drop 1 or more columns.
    
+
    function SetSchema($schema)
    
+
    Set the schema.
    
+
    function MetaTables()
    
+
    function MetaColumns($tab, $upper=true, $schema=false)
    
+
    function MetaPrimaryKeys($tab,$owner=false,$intkey=false)
    
+
    function MetaIndexes($table, $primary = false, $owner = false)
    
+
    These functions are wrappers for the corresponding functions in the
+connection object. However, the table names will be autoquoted by the
+TableName function (see below) before being passed to the connection
+object.
    
+
    function NameQuote($name = NULL)
    
+
    If the provided name is quoted with backquotes (`) or contains
+special characters, returns the name quoted with the appropriate quote
+character, otherwise the name is returned unchanged.
    
+
    function TableName($name)
    
+
    The same as NameQuote, but will prepend the current schema if
+specified
    
+
    function MetaType($t,$len=-1,$fieldobj=false)
    
+
    function ActualType($meta)
    
+
    Convert between database-independent 'Meta' and database-specific
+'Actual' type codes.
    
+
    function ExecuteSQLArray($sqlarray, $contOnError = true)
    
+
      RETURNS:      0 if failed, 1 if executed all but with errors, 2 if executed successfully
      $sqlarray:    an array of strings with sql code (no semicolon at the end of string)
      $contOnError: if true, then continue executing even if error occurs
    
+
    Executes an array of SQL strings returned by CreateTableSQL or
+CreateIndexSQL.
    
+
    
+
+
    ADOdb XML Schema (AXMLS)
    
+
    This is a class contributed by Richard Tango-Lowy and Dan Cech that
+allows the user to quickly
+and easily build a database using the excellent ADODB database library
+and a simple XML formatted file.

+the latest version of AXMLS here.
    
+
    Quick Start
    
+
    Adodb-xmlschema, or AXMLS, is a set of classes that allow the user
+to quickly and easily build or upgrade a database on almost any RDBMS
+using the excellent ADOdb database library and a simple XML formatted
+schema file. Our goal is to give developers a tool that's simple to
+use, but that will allow them to create a single file that can build,
+upgrade, and manipulate databases on most RDBMS platforms.
    
+ Installing axmls
+
    The easiest way to install AXMLS to download and install any recent
+version of the ADOdb database abstraction library. To install AXMLS
+manually, simply copy the adodb-xmlschema.inc.php file and the xsl
+directory into your adodb directory.
    
+ Using AXMLS in Your Application
+
    There are two steps involved in using AXMLS in your application:
+first, you must create a schema, or XML representation of your
+database, and second, you must create the PHP code that will parse and
+execute the schema.
    
+
    Let's begin with a schema that describes a typical, if simplistic
+user management table for an application.
    
+
    <?xml version="1.0"?>
    <schema version="0.2">

      <table name="users">
        <desc>A typical users table for our application.</desc>
        <field name="userId" type="I">
          <descr>A unique ID assigned to each user.</descr>

          <KEY/>
          <AUTOINCREMENT/>
        </field>
        
        <field name="userName" type="C" size="16"><NOTNULL/></field>

        
        <index name="userName">
          <descr>Put a unique index on the user name</descr>
          <col>userName</col>
          <UNIQUE/>

        </index>
      </table>
      
      <sql>
        <descr>Insert some data into the users table.</descr>
        <query>insert into users (userName) values ( 'admin' )</query>

        <query>insert into users (userName) values ( 'Joe' )</query>
      </sql>
    </schema>			
    
+
    Let's take a detailed look at this schema.
    
+
    The opening <?xml version="1.0"?> tag is required by XML. The
+<schema> tag tells the parser that the enclosed markup defines an
+XML schema. The version="0.2" attribute sets the version of the
+AXMLS DTD used by the XML schema. 
    
+
    All versions of AXMLS prior to version 1.0 have a schema version of
+"0.1". The current schema version is "0.2".
    
+
    <?xml version="1.0"?>
    <schema version="0.2">
      ...
    </schema>
    
+
    Next we define one or more tables. A table consists of a fields (and
+other objects) enclosed by <table> tags. The name="" attribute
+specifies the name of the table that will be created in the database.
    
+
    <table name="users">

        <desc>A typical users table for our application.</desc>
        <field name="userId" type="I">

          <descr>A unique ID assigned to each user.</descr>
          <KEY/>
          <AUTOINCREMENT/>
        </field>
        
        <field name="userName" type="C" size="16"><NOTNULL/></field>

        
    </table>
    
+
    This table is called "users" and has a description and two fields.
+The description is optional, and is currently only for your own
+information; it is not applied to the database.
    
+
    The first <field> tag will create a field named "userId" of
+type "I", or integer. (See the ADOdb Data Dictionary documentation for
+a list of valid types.) This <field> tag encloses two special
+field options: <KEY/>, which specifies this field as a primary
+key, and <AUTOINCREMENT/>, which specifies that the database
+engine should automatically fill this field with the next available
+value when a new row is inserted.
    
+
    The second <field> tag will create a field named "userName" of
+type "C", or character, and of length 16 characters. The
+<NOTNULL/> option specifies that this field does not allow NULLs.
    
+
    There are two ways to add indexes to a table. The simplest is to
+mark a field with the <KEY/> option as described above; a primary
+key is a unique index. The second and more powerful method uses the
+<index> tags.
    
+
    <table name="users">
      ...
        
      <index name="userName">
        <descr>Put a unique index on the user name</descr>
        <col>userName</col>

        <UNIQUE/>
      </index>
        
    </table>
    
+
    The <index> tag specifies that an index should be created on
+the enclosing table. The name="" attribute provides the name of the
+index that will be created in the database. The description, as above,
+is for your information only. The <col> tags list each column
+that will be included in the index. Finally, the <UNIQUE/> tag
+specifies that this will be created as a unique index.
    
+
    Finally, AXMLS allows you to include arbitrary SQL that will be
+applied to the database when the schema is executed.
    
+
    <sql>
      <descr>Insert some data into the users table.</descr>
      <query>insert into users (userName) values ( 'admin' )</query>

      <query>insert into users (userName) values ( 'Joe' )</query>
    </sql>
    
+
    The <sql> tag encloses any number of SQL queries that you
+define for your own use.
    
+
    Now that we've defined an XML schema, you need to know how to apply
+it to your database. Here's a simple PHP script that shows how to load
+the schema.
    
+
    <?PHP
    /* You must tell the script where to find the ADOdb and
     * the AXMLS libraries.
     */
+require( "path_to_adodb/adodb.inc.php");
+require( "path_to_adodb/adodb-xmlschema.inc.php" ); # or adodb-xmlschema03.inc.php
+
+/* Configuration information. Define the schema filename,
     * RDBMS platform (see the ADODB documentation for valid
     * platform names), and database connection information here.
     */
    $schemaFile = 'example.xml';
    $platform = 'mysql';
    $dbHost = 'localhost';
    $dbName = 'database';
    $dbUser = 'username';
    $dbPassword = 'password';

    /* Start by creating a normal ADODB connection.
     */
    $db = ADONewConnection( $platform );
    $db->Connect( $dbHost, $dbUser, $dbPassword, $dbName );

    /* Use the database connection to create a new adoSchema object.
     */
    $schema = new adoSchema( $db );

    /* Call ParseSchema() to build SQL from the XML schema file.
     * Then call ExecuteSchema() to apply the resulting SQL to 
     * the database.
     */
    $sql = $schema->ParseSchema( $schemaFile );
    $result = $schema->ExecuteSchema();
    ?>
    
+
    Let's look at each part of the example in turn. After you manually
+create the database, there are three steps required to load (or
+upgrade) your schema.
    
+
    First, create a normal ADOdb connection. The variables and values
+here should be those required to connect to your database.
    
+
    $db = ADONewConnection( 'mysql' );
    $db->Connect( 'host', 'user', 'password', 'database' );
    
+
    Second, create the adoSchema object that load and manipulate your
+schema. You must pass an ADOdb database connection object in order to
+create the adoSchema object.
    
+
    $schema = new adoSchema( $db );
    
+
    Third, call ParseSchema() to parse the schema and then
+ExecuteSchema() to apply it to the database. You must pass
+ParseSchema() the path and filename of your schema file.
    
+
    $schema->ParseSchema( $schemaFile ); 
    $schema->ExecuteSchema();
    
+
    Execute the above code and then log into your database. If you've
+done all this right, you should see your tables, indexes, and SQL.
    
+
    You can find the source files for this tutorial in the examples
+directory as tutorial_shema.xml and tutorial.php. See the class
+documentation for a more detailed description of the adoSchema methods,
+including methods and schema elements that are not described in this
+tutorial.
    
+
    XML Schema Version 3
    
+
    In March 2006, we added adodb-xmlschema03.inc.php to the release, which supports version 3 of XML Schema. 
+The adodb-xmlschema.inc.php remains the same as previous releases, and supports version 2 of XML Schema. 
+Version 3 provides some enhancements:
+
+
      
+     
    •  Support for updating table data during an upgrade.
+     
    •  Support for platform-specific table options and platform negation.
+     
    •  Support for unsigned fields.
+     
    •  Fixed opt and constraint support
+     
    •  Many other fixes such as OPT tag, which allows you to set optional platform settings:
+
    
+
+
    Example usage:
+
    <?xml version="1.0"?>
+<schema version="0.3">
+ <table name="ats_kb">
+  <descr>ATS KnowledgeBase</descr>
+  <opt platform="mysql">TYPE=INNODB</opt>
+  <field name="recid" type="I"/>
+  <field name="organization_code" type="I4"/> 
+  <field name="sub_code" type="C" size="20"/>
+  etc...
+
    
+
    To use it, change your code to include adodb-xmlschema03.inc.php.
+
+
    Upgrading
    
+
    
+If your schema version is older, than XSLT is used to transform the
+schema to the newest version. This means that if you are using an older
+XML schema format, you need to have the XSLT extension installed.
+If you do not want to require your users to have the XSLT extension
+installed, make sure you modify your XML schema to conform to the
+latest version.

    Using ADOdb with PHP and Oracle: an advanced tutorial
    
+
    
+
    (c)2004-2005 John Lim. All rights reserved.
    
+
    1. Introduction
    
+
    Oracle is the most popular commercial database used with PHP. There are many ways of accessing Oracle databases in PHP. These include:
    
+
      
+  
    • The oracle extension
      • 
+  
    • The oci8 extension
      • 
+  
    • PEAR DB library
      • 
+  
    • ADOdb library
      • 
+
    
+
    The wide range of choices is confusing to someone just starting with Oracle and PHP. I will briefly summarize the differences, and  show you the advantages of using ADOdb. 
    
+
    First we have the C extensions which provide low-level access to Oracle functionality. These C extensions are precompiled into PHP, or linked in dynamically when the web server starts up. Just in case you need it, here's a guide to installing Oracle and PHP on Linux.
    
+
+  
+    
+    
+  
+  
+    
+    
+  
+
    Oracle extensionDesigned for Oracle 7 or earlier. This is obsolete.
    Oci8 extension Despite it's name, which implies it is only for Oracle 8i, this is the standard method for accessing databases running Oracle 8i, 9i or 10g (and later).
    
+
    Here is an example of using the oci8 extension to query the emp table of the scott schema with bind parameters:
+
    +$conn = OCILogon("scott","tiger", $tnsName); 
+
+$stmt = OCIParse($conn,"select * from emp where empno > :emp order by empno"); 
+$emp = 7900;
+OCIBindByName($stmt, ':emp', $emp);
+$ok = OCIExecute($stmt);
+while (OCIFetchInto($stmt,$arr)) {
+	print_r($arr);
+	echo "<hr>";	
+} 
+
    
+
    This generates the following output:
+
    
+Array ( [0] => 7902 [1] => FORD [2] => ANALYST [3] => 7566 [4] => 03/DEC/81 [5] => 3000 [7] => 20 ) 
+
    
+  Array ( [0] => 7934 [1] => MILLER [2] => CLERK [3] => 7782 [4] => 23/JAN/82 [5] => 1300 [7] => 10 )
+
    
+
    We also have  many higher level PHP libraries that allow you to simplify the above code. The most popular are PEAR DB and ADOdb.  Here are some of the differences between these libraries:

+
     PEAR DB is good enough for simple web apps. But if you need more power, you can see ADOdb offers more sophisticated functionality. The rest of this article will concentrate on using ADOdb with Oracle. You can find out more about connecting to Oracle later in this guide.
    
+
    ADOdb Example
    
+
    In ADOdb, the above oci8 example querying the emp table could be written as:
    
+
    +include "/path/to/adodb.inc.php";
+$db = NewADOConnection("oci8");
+$db->Connect($tnsName, "scott", "tiger");
+
+$rs = $db->Execute("select * from emp where empno>:emp order by empno", 
+                    array('emp' => 7900));
+while ($arr = $rs->FetchRow()) {
+    print_r($arr);
+	echo "<hr>";
+}
+
    
+
    The Execute( ) function returns a recordset object, and you can retrieve the rows returned using $recordset->FetchRow( ). 
    
+
    If we ignore the initial connection preamble, we can see the ADOdb version is much easier and simpler:
    
+
+  
+    
+    
+  
+  
+    
+    
+  
+
    Oci8ADOdb
    $stmt = OCIParse($conn,
+       "select * from emp where empno > :emp"); 
+$emp = 7900;
+OCIBindByName($stmt, ':emp', $emp);
+$ok = OCIExecute($stmt);
+
+while (OCIFetchInto($stmt,$arr)) {
+	print_r($arr);
+	echo "<hr>";	
+} 
    $recordset = $db->Execute("select * from emp where empno>:emp", 
+                           array('emp' => 7900));
+
+while ($arr = $recordset->FetchRow()) {
+	print_r($arr);
+	echo "<hr>";
+}
    
+
     
    
+
    2. ADOdb Query Semantics
    
+
    You can also query the database using the standard Microsoft ADO MoveNext( ) metaphor. The data array for the current row is stored in the fields property of the recordset object, $rs.
+MoveNext( ) offers the highest performance among all the techniques for iterating through a recordset:
+
    +$rs = $db->Execute("select * from emp where empno>:emp", array('emp' => 7900));
+while (!$rs->EOF) {
+	print_r($rs->fields);
+	$rs->MoveNext();
+}
+
    
+
    And if you are interested in having the data returned in a 2-dimensional array, you can use:
+
    +$arr = $db->GetArray("select * from emp where empno>:emp", array('emp' => 7900));
+
    
+
    Now to obtain only the first row as an array:
+
    +$arr = $db->GetRow("select * from emp where empno=:emp", array('emp' => 7900));
+
    
+
    Or to retrieve only the first field of the first row:
+
    +$arr = $db->GetOne("select ename from emp where empno=:emp", array('emp' => 7900));
+
    
+
    For easy pagination support, we provide the SelectLimit function. The following will perform a select query, limiting it to 100 rows, starting from row 201 (row 1 being the 1st row):
+
    +$offset = 200; $limitrows = 100;
+$rs = $db->SelectLimit('select * from table', $limitrows, $offset);
+
    
+
    The $offset parameter is optional.
+
    Array Fetch Mode
    
+
    When data is being returned in an array, you can choose the type of array the data is returned in. 
+
      
+  
    1.  Numeric indexes - use $connection->SetFetchMode(ADODB_FETCH_NUM).
      2. 
+  
    2. Associative indexes - the keys of the array are the names of the fields (in upper-case). Use $connection->SetFetchMode(ADODB_FETCH_ASSOC).
      3. 
+  
    3. Both numeric and associative indexes - use $connection->SetFetchMode(ADODB_FETCH_BOTH).
      4. 
+
    
+
    The default is ADODB_FETCH_BOTH for Oracle.
    
+
    Caching
    
+
    You can define a database cache directory using $ADODB_CACHE_DIR, and cache the results of frequently used queries that rarely change. This is particularly useful for SQL with complex where clauses and group-by's and order-by's. It is also good for relieving heavily-loaded database servers.
    
+
    This example will cache the following select statement for 3600 seconds (1 hour):
    
+
    +$ADODB_CACHE_DIR = '/var/adodb/tmp';
+$rs = $db->CacheExecute(3600, "select names from allcountries order by 1");
+
    
+There are analogous CacheGetArray(
+), CacheGetRow( ),  CacheGetOne( ) and CacheSelectLimit( )  functions. The first parameter is the number of seconds to cache. You can also pass a bind array as a 3rd parameter (not shown above).
+
    There is an alternative syntax for the caching functions. The first parameter is omitted, and you set the cacheSecs
+ property of the connection object:
+
    +$ADODB_CACHE_DIR = '/var/adodb/tmp';
+$connection->cacheSecs = 3600;
+$rs = $connection->CacheExecute($sql, array('id' => 1));
+
    
+
     
    
+
    3. Using Prepare( ) For Frequently Used Statements
    
+
    Prepare( ) is  for compiling frequently used  SQL statement for reuse. For example, suppose we have a large array which needs to be inserted into an Oracle database. The following will result in a massive speedup in query execution (at least 20-40%), as the SQL statement only needs to be compiled once:
    
+
    +$stmt = $db->Prepare('insert into table (field1, field2) values (:f1, :f2)');
+foreach ($arrayToInsert as $key => $value) {
+	$db->Execute($stmt, array('f1' => $key, 'f2' => $val);
+}
+
    
+
     
    
+
    4. Working With LOBs
    
+
    Oracle treats data which is more than 4000 bytes in length specially. These are called Large Objects, or LOBs for short. Binary LOBs are BLOBs, and character LOBs are CLOBs. In most Oracle libraries, you need to do a lot of work to process LOBs, probably because Oracle designed it to work in systems with little memory. ADOdb tries to make things easy by assuming the LOB can fit into main memory. 
    
+
    ADOdb will transparently handle LOBs  in select statements. The LOBs are automatically converted to PHP variables without any special coding.
    
+
    For updating records with LOBs, the functions UpdateBlob( ) and UpdateClob( ) are provided. Here's a BLOB example. The parameters should be self-explanatory:
+
    +$ok = $db->Execute("insert into aTable (id, name, ablob) 
+                                values (aSequence.nextVal, 'Name', null)");
+if (!$ok) return LogError($db->ErrorMsg());
+# params: $tableName, $blobFieldName, $blobValue, $whereClause
+$db->UpdateBlob('aTable', 'ablob', $blobValue, 'id=aSequence.currVal');
+
    
+
    and the analogous CLOB example:
+
    +$ok = $db->Execute("insert into aTable (id, name, aclob) 
+                                values (aSequence.nextVal, 'Name', null)");
+if (!$ok) return LogError($db->ErrorMsg());
+$db->UpdateClob('aTable', 'aclob', $clobValue, 'id=aSequence.currVal');
+
    
+
    Note that LogError( ) is a user-defined function, and not part of ADOdb.
+
    Inserting LOBs is more complicated. Since ADOdb 4.55, we allow you to do this
+  (assuming that the photo field is a BLOB, and we want to store $blob_data into
+  this field, and the primary key is the id field):
+
    +	$sql = "INSERT INTO photos ( ID, photo) ".
+			"VALUES ( :id, empty_blob() )".
+			" RETURNING photo INTO :xx";
+
+ 		$stmt = $db->PrepareSP($sql);
+		$db->InParameter($stmt, $id, 'id');
+		$blob = $db->InParameter($stmt, $blob_data, 'xx',-1, OCI_B_BLOB);
+		$db->StartTrans();
+		$ok = $db->Execute($stmt);
+		$db->CompleteTrans();
+
     
+
    
+
    5. REF CURSORs
    
+
    Oracle recordsets can be passed around as variables called REF Cursors. For example, in PL/SQL, we could define a function open_tab that returns a REF CURSOR in the first parameter:
    
+
    +TYPE TabType IS REF CURSOR RETURN TAB%ROWTYPE;
+
+PROCEDURE open_tab (tabcursor IN OUT TabType,tablenames IN VARCHAR) IS
+	BEGIN
+		OPEN tabcursor FOR SELECT * FROM TAB WHERE tname LIKE tablenames;
+	END open_tab;
+
    
+
    In ADOdb, we could access this REF Cursor using the ExecuteCursor() function. The following will find
+ all table names that begin with 'A' in the current schema:
+
    +$rs = $db->ExecuteCursor("BEGIN open_tab(:refc,'A%'); END;",'refc');
+while ($arr = $rs->FetchRow()) print_r($arr);
+
    
+
    The first parameter is the PL/SQL statement, and the second parameter is the name of the REF Cursor.
+
    
+
     
    
+
    6. In and Out Parameters
    
+
    The following PL/SQL
+stored procedure  requires an input  variable, and returns a result into an output variable:
+
    +PROCEDURE data_out(input IN VARCHAR, output OUT VARCHAR) IS
+	BEGIN
+		output := 'I love '||input;
+	END;
+
    
+
    The following ADOdb code allows you to call the stored procedure:
    
+
    +$stmt = $db->PrepareSP("BEGIN adodb.data_out(:a1, :a2); END;");
+$input = 'Sophia Loren';
+$db->InParameter($stmt,$input,'a1');
+$db->OutParameter($stmt,$output,'a2');
+$ok = $db->Execute($stmt);
+if ($ok) echo ($output == 'I love Sophia Loren') ? 'OK' : 'Failed';
+
    
+
    PrepareSP( ) is a special function that knows about bind parameters.
+The main limitation currently is that IN OUT parameters do not work.
+
    Bind Parameters and REF CURSORs
    
+
    We could also rewrite the REF CURSOR example to use InParameter (requires ADOdb 4.53 or later):
+
    +$stmt = $db->PrepareSP("BEGIN adodb.open_tab(:refc,:tabname); END;");
+$input = 'A%';
+$db->InParameter($stmt,$input,'tabname');
+$rs = $db->ExecuteCursor($stmt,'refc');
+while ($arr = $rs->FetchRow()) print_r($arr);
+
    
+
    Bind Parameters and LOBs
    
+
    You can also operate on LOBs. In this example, we have IN and OUT parameters using CLOBs. 
+
    +	$text = 'test test test';
+	$sql = "declare rs clob; begin :rs := lobinout(:sa0); end;";
+	$stmt = $conn -> PrepareSP($sql);
+	$conn -> InParameter($stmt,$text,'sa0', -1, OCI_B_CLOB); # -1 means variable length
+	$rs = '';
+	$conn -> OutParameter($stmt,$rs,'rs', -1, OCI_B_CLOB);
+	$conn -> Execute($stmt);
+	echo "return = ".$rs."<br>";
+
    
+
    Similarly, you can use the constant OCI_B_BLOB to indicate that you are using BLOBs.
+
    Reusing Bind Parameters with CURSOR_SHARING=FORCE
    
+
    Many web programmers do not care to use bind parameters, and prefer to enter the SQL directly. So instead of:
    
+
    +$arr = $db->GetArray("select * from emp where empno>:emp", array('emp' => 7900));
+
    
+
    They prefer  entering the values inside the SQL:
+
    +$arr = $db->GetArray("select * from emp where empno>7900");
+
    
+
    This reduces Oracle performance because Oracle will reuse compiled SQL which is identical to previously compiled SQL. The above example with the values inside the SQL
+is unlikely to be reused. As an optimization, from Oracle 8.1 onwards, you can set the following session parameter after you login:
+
    +ALTER SESSION SET CURSOR_SHARING=FORCE
+
    
+
    This will force Oracle to convert all such variables (eg. the 7900 value) into constant bind parameters, improving SQL reuse.
    
+
    More speedup tips.
    
+
     
    
+
    7. Dates and Datetime in ADOdb
    
+
    There are two things you need to know about dates in ADOdb. 
    
+
    First, to ensure cross-database compability, ADOdb assumes that dates are returned in ISO format (YYYY-MM-DD H24:MI:SS).
    
+
    Secondly, since Oracle treats dates and datetime as the same data type, we decided not to display the time in the default date format. So on login, ADOdb will set the NLS_DATE_FORMAT to 'YYYY-MM-DD'. If you prefer to show the date and time by default, do this:
    
+
    +$db = NewADOConnection('oci8');
+$db->NLS_DATE_FORMAT =  'RRRR-MM-DD HH24:MI:SS';
+$db->Connect($tns, $user, $pwd);
+
    
+
    Or execute:
    
+
    $sql = quot;ALTER SESSION SET NLS_DATE_FORMAT = 'RRRR-MM-DD HH24:MI:SS'";
+$db->Execute($sql);
+
    
+
    If you are not concerned about date portability and do not use ADOdb's portability layer, you can use your preferred date format instead.
+
    
+
    8. Database Portability Layer
    
+
    ADOdb provides the following functions for portably generating SQL functions 
+  as strings to be merged into your SQL statements:
    
+
+   
+    
+    
+  
+   
+    
+    
+  
+   
+    
+    
+  
+   
+    
+    
+  
+   
+    
+    
+  
+   
+    
+    
+  
+   
+    
+    
+  
+  
+    
+    
+  
+  
+
+
+
+
+
+
+
+
+
+
+
+
+
    FunctionDescription
    DBDate($date)Pass in a UNIX timestamp or ISO date and it will convert it to a date 
+      string formatted for INSERT/UPDATE
    DBTimeStamp($date)Pass in a UNIX timestamp or ISO date and it will convert it to a timestamp 
+      string formatted for INSERT/UPDATE
    SQLDate($date, $fmt)Portably generate a date formatted using $fmt mask, for use in SELECT 
+      statements.
    OffsetDate($date, $ndays)Portably generate a $date offset by $ndays.

    $db->sysTimeStampProperty that holds the SQL function that returns the current
+timestamp (date+time).
+
    $db->concat_operatorProperty that holds the concatenation operator
+
    $db->lengthProperty that holds the name of the SQL strlen function.
+
    $db->upperCaseProperty that holds the name of the SQL strtoupper function.
+
    $db->randomProperty that holds the SQL to generate a random number between 0.00 and 1.00.
+
    $db->substrProperty that holds the name of the SQL substring function.
+
    
+
    ADOdb also provides multiple oracle oci8 drivers for different scenarios:
    
+
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+
    Driver NameDescription
    oci805 Specifically for Oracle 8.0.5. This driver has a slower SelectLimit( ).
    oci8The default high performance driver. The keys of associative arrays returned in a recordset are upper-case.
    oci8po The portable Oracle driver. Slightly slower than oci8. This driver uses ? instead of :bindvar for binding variables, which is the standard for  other databases. Also the keys of associative arrays are in lower-case like other databases.
    
+
    Here's an example of calling the oci8po driver. Note that the bind variables use question-mark:
    
+
    $db = NewADOConnection('oci8po');
+$db->Connect($tns, $user, $pwd);
+$db->Execute("insert into atable (f1, f2) values (?,?)", array(12, 'abc'));
    
+
     
+
    9. Connecting to Oracle
    
+
    Before you can use ADOdb, you need to have the Oracle client installed and setup the oci8 extension. This extension comes pre-compiled for Windows (but you still need to enable it in the php.ini file). For information on compiling the oci8 extension for PHP and Apache on Unix, there is an excellent guide at oracle.com. 
    
+
    Should You Use Persistent Connections
    
+
    One question that is frequently asked is should you use persistent connections to Oracle. Persistent connections allow PHP to recycle existing connections, reusing them after the previous web pages have completed. Non-persistent connections close automatically after the web page has completed. Persistent connections are faster because the cost of reconnecting is expensive, but there is additional resource overhead. As an alternative, Oracle allows you to pool and reuse server processes; this is called  Shared Server (also known as MTS).
    
+
    The author's benchmarks suggest that using non-persistent connections and the  Shared Server configuration offer the best performance. If Shared Server is not an option, only then consider using persistent connections.
    
+
    Connection Examples
    
+
    Just in case you are having problems connecting to Oracle, here are some examples:
    
+
    a. PHP and Oracle reside on the same machine, use default SID, with non-persistent connections:
    
+
    	$conn = NewADOConnection('oci8');
+	$conn->Connect(false, 'scott', 'tiger');
    
+
    b. TNS Name defined in tnsnames.ora (or ONAMES or HOSTNAMES), eg. 'myTNS', using persistent connections:
    
+
    	$conn = NewADOConnection('oci8');
+	$conn->PConnect(false, 'scott', 'tiger', 'myTNS');
    
+
    or
    
+
     	$conn->PConnect('myTNS', 'scott', 'tiger');
    
+
    c. Host Address and SID
    
+
    +	$conn->connectSID = true;	
+	$conn->Connect('192.168.0.1', 'scott', 'tiger', 'SID');
    
+
    d. Host Address and Service Name
    
+
    	$conn->Connect('192.168.0.1', 'scott', 'tiger', 'servicename');
    
+
    e. Oracle connection string:
+
    	$cstr = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=$host)(PORT=$port))
+			(CONNECT_DATA=(SID=$sid)))";
+	$conn->Connect($cstr, 'scott', 'tiger');
+
    
+
    f. ADOdb data source names (dsn):
+
    +	$dsn = 'oci8://user:pwd@tnsname/?persist';  # persist is optional
+	$conn = ADONewConnection($dsn);  # no need for Connect/PConnect
+	
+	$dsn = 'oci8://user:pwd@host/sid';
+	$conn = ADONewConnection($dsn);
+	
+	$dsn = 'oci8://user:pwd@/';   # oracle on local machine
+	$conn = ADONewConnection($dsn);
    
+
    With ADOdb data source names,
+you don't have to call Connect( ) or PConnect( ).
+
    
+
     
    
+
    10. Error Checking
    
+
    The examples in this article are easy to read but a bit simplistic because we ignore error-handling. Execute( ) and Connect( ) will return false on error. So a more realistic way to call Connect( ) and Execute( ) is:
+
    function InvokeErrorHandler()
+{
    global $db; ## assume global
+    MyLogFunction($db->ErrorNo(), $db->ErrorMsg());
+}
+if (!$db->Connect($tns, $usr, $pwd)) InvokeErrorHandler();
+
+$rs = $db->Execute("select * from emp where empno>:emp order by empno", 
+                    array('emp' => 7900));
+if (!$rs) return InvokeErrorHandler();
+while ($arr = $rs->FetchRow()) {
+    print_r($arr);
+	echo "<hr>";
+}
+
    
+
    You can retrieve the  error message and error number of the last SQL statement executed from ErrorMsg( ) and ErrorNo( ). You can also define a custom error handler function.
+ADOdb also supports throwing exceptions in PHP5.
+
     
    
+
    Handling Large Recordsets (added 27 May 2005)
    
+The oci8 driver does not support counting the number of records returned in a SELECT statement, so the function RecordCount() 
+is emulated when the global variable $ADODB_COUNTRECS is set to true, which is the default. 
+We emulate this by buffering all the records. This can take up large amounts of memory for big recordsets.
+ Set $ADODB_COUNTRECS to false for the best performance. 
+ 
    
+This variable is checked every time a query is executed, so you can selectively choose which recordsets to count.
+
     
    
+
    11. Other ADOdb Features
    
+
    Schema generation. This allows you to define a schema using XML and import it into different RDBMS systems portably.
    
+
    Performance monitoring and tracing. Highlights of performance monitoring include identification of poor and suspicious SQL, with explain plan support, and identifying which web pages the SQL ran on.

+
    Introduction
    
+
    This module, part of the ADOdb package, provides both CLI and HTML
+interfaces for viewing key performance indicators of your database.
+This is very useful because web apps such as the popular phpMyAdmin
+currently do not provide effective database health monitoring tools.
+The module provides the following: 
    
+
      
+  
    • A quick health check of your database server using $perf->HealthCheck()
+or $perf->HealthCheckCLI(). 
      • 
+  
    • User interface for performance monitoring, $perf->UI().
+This UI displays:
+    
        
+      
      • the health check, 
        • 
+      
      • all SQL logged and their query plans, 
        • 
+      
      • a list of all tables in the current database
        • 
+      
      • an interface to continiously poll the server for key
+performance indicators such as CPU, Hit Ratio, Disk I/O
        • 
+      
      • a form where you can enter and run SQL interactively.
        • 
+    
      
+  
      • 
+  
    • Gives you an API to build database monitoring tools for a server
+farm, for example calling $perf->DBParameter('data cache hit
+ratio') returns this very important statistic in a database
+independant manner. 
      • 
+
    
+
    ADOdb also has the ability to log all SQL executed, using LogSQL. All SQL logged can be
+analyzed through the performance monitor UI. In the View
+SQL mode, we categorize the SQL into 3 types:
+
    
+
      
+  
    • Suspicious SQL: queries with high average execution times,
+and are potential candidates for rewriting
      • 
+  
    • Expensive SQL: queries with high total execution times
+(#executions * avg execution time). Optimizing these queries will
+reduce your database server load.
      • 
+  
    • Invalid SQL: queries that generate errors.
      • 
+
    
+
    Each query is hyperlinked to a description of the query plan, and
+every PHP script that executed that query is also shown.
    
+
    Please note that the information presented is a very basic database
+health check, and does not provide a complete overview of database
+performance. Although some attempt has been made to make it work across
+multiple databases in the same way, it is impossible to do so. For the
+health check, we do try to display the following key database
+parameters for all drivers:
    
+
      
+  
    • data cache size - The amount of memory allocated to the
+cache.
      • 
+  
    • data cache hit ratio - A measure of how effective the
+cache is, as a percentage. The higher, the better.
      • 
+  
    • current connections - The number of sessions currently
+connected to the database. 
      • 
+
    
+
    You will need to connect to the database as an administrator to view
+most of the parameters. 
    
+
    Code improvements as very welcome, particularly adding new database
+parameters and automated tuning hints.
    
+
+
    Usage
    
+
    Currently, the following drivers: mysql, postgres,
+oci8, mssql, informix and db2 are
+supported. To create a new performance monitor, call NewPerfMonitor( )
+as demonstrated below: 
    
+
    <?php
    include_once('adodb.inc.php');
    session_start(); # session variables required for monitoring
    $conn = ADONewConnection($driver);
    $conn->Connect($server,$user,$pwd,$db);
    $perf =& NewPerfMonitor($conn);
    $perf->UI($pollsecs=5);
    ?>
    
+
    It is also possible to retrieve a single database parameter:
    
+
    $size = $perf->DBParameter('data cache size');
    
+
    
+Thx to Fernando Ortiz for the informix module. 
    
+
    Methods
    
+
+
    function UI($pollsecs=5)
    
+
    Creates a web-based user interface for performance monitoring. When
+you click on Poll, server statistics will be displayed every $pollsecs
+seconds. See Usage above. 
    
+
    Since 4.11, we allow users to enter and run SQL interactively via
+the "Run SQL" link. To disable this for security reasons, set this
+constant before calling $perf->UI(). 
    
+
     
    
+
    define('ADODB_PERF_NO_RUN_SQL',1);

    WS-CPU% is the Web Server CPU load of the server that PHP is
+running from (eg. the database client), and not the database. The Hit%
+is the data cache hit ratio. Sess is the current number of
+sessions connected to the database. If you are using persistent
+connections, this should not change much. The Reads/s and Writes/s
+are synthetic values to give the viewer a rough guide to I/O, and are
+not to be taken literally. 
    
+
    function SuspiciousSQL($numsql=10)
    
+
    Returns SQL which have high average execution times as a HTML table.
+Each sql statement
+is hyperlinked to a new window which details the execution plan and the
+scripts that execute this SQL.
+
    
+
     The number of statements returned is determined by $numsql. Data is
+taken from the adodb_logsql table, where the sql statements are logged
+when
+$connection->LogSQL(true) is enabled. The adodb_logsql table is
+populated using $conn->LogSQL.
+
    
+
    For Oracle, Ixora Suspicious SQL returns a list of SQL statements
+that are most cache intensive as a HTML table. These are data intensive
+SQL statements that could benefit most from tuning. 
    
+
    function ExpensiveSQL($numsql=10)
    
+
    Returns SQL whose total execution time (avg time * #executions) is
+high as a HTML table. Each sql statement
+is hyperlinked to a new window which details the execution plan and the
+scripts that execute this SQL.
+
    
+
     The number of statements returned is determined by $numsql. Data is
+taken from the adodb_logsql table, where the sql statements are logged
+when
+$connection->LogSQL(true) is enabled. The adodb_logsql table is
+populated using $conn->LogSQL.
+
    
+
    For Oracle, Ixora Expensive SQL returns a list of SQL statements
+that are taking the most CPU load when run.
+
    
+
    function InvalidSQL($numsql=10)
    
+
    Returns a list of invalid SQL as an HTML table.
+
    
+
    Data is taken from the adodb_logsql table, where the sql statements
+are logged when
+$connection->LogSQL(true) is enabled.
+
    
+
    function Tables($orderby=1)
    
+
    Returns information on all tables in a database, with the first two
+fields containing the table name and table size, the remaining fields
+depend on the database driver. If $orderby is set to 1, it will sort by
+name. If $orderby is set to 2, then it will sort by table size. Some
+database drivers (mssql and mysql) will ignore the $orderby clause. For
+postgresql, the information is up-to-date since the last vacuum.
+Not supported currently for db2.
    
+
    Raw Functions
    
+
    Raw functions return values without any formatting.
    
+
    function DBParameter($paramname)
    
+
    Returns the value of a database parameter, such as
+$this->DBParameter("data cache size").
    
+
    function CPULoad()
    
+
    Returns the CPU load of the database client (NOT THE SERVER) as a
+percentage. Only works for Linux and Windows. For Windows, WMI must be
+available.
    
+
    $ADODB_PERF_MIN
    
+
    New in adodb 4.97/5.03 is this global variable, which controls whether sql timings which are too small are not saved. Currently it defaults 
+to 0.05 (seconds). This means that all sql's which are faster than 0.05 seconds to execute are not saved.
+
    Format of $settings Property
    
+
     To create new database parameters, you need to understand
+$settings. The $settings data structure is an associative array. Each
+element of the array defines a database parameter. The key is the name
+of the database parameter. If no key is defined, then it is assumed to
+be a section break, and the value is the name of the section break. If
+this is too confusing, looking at the source code will help a lot!
    
+
     Each database parameter is itself an array consisting of the
+following elements:
    
+
      
+  
    1.  Category code, used to group related db parameters. If the
+category code is 'HIDE', then
+the database parameter is not shown when HTML() is called. 
      
+  
      2. 
+  
    2.  either
+    
        
+      
      1. sql string to retrieve value, eg. "select value from
+v\$parameter where name='db_block_size'", 
        2. 
+      
      2. array holding sql string and field to look for, e.g.
+array('show variables','table_cache'); optional 3rd parameter is the
+$rs->fields[$index] to use (otherwise $index=1), and optional 4th
+parameter is a constant to multiply the result with (typically 100 for
+percentage calculations),
        3. 
+      
      3. a string prefixed by =, then a PHP method of the class is
+invoked, e.g. to invoke $this->GetIndexValue(), set this array
+element to '=GetIndexValue', 
        
+      
        4. 
+    
      
+  
      3. 
+  
    3.  Description of database parameter. If description begins with an
+=, then it is interpreted as a method call, just as in (1c) above,
+taking one parameter, the current value. E.g. '=GetIndexDescription'
+will invoke $this->GetIndexDescription($val). This is useful for
+generating tuning suggestions. For an example, see WarnCacheRatio().
      4. 
+
    
+
    Example from MySQL, table_cache database parameter:
    
+
    'table cache' =gt; array('CACHE',            # category code
       array("show variables", 'table_cache'), # array (type 1b)
       'Number of tables to keep open'),       # description

    Introduction
    
+
     This document discusses the newer session handler adodb-session2.php. If
+  you have used the older adodb-session.php, then be forewarned that you will
+  need to alter your session table format. Otherwise everything is backward
+  compatible.
+  Here are the older
+    docs for
+  adodb-session.php.
    
+
    Why Session Variables in a Database? 
    
+
    We store state information specific to a user or web
+    client in session variables. These session variables persist throughout a
+session, as the user moves from page to page. 
    
+
    To use session variables, call session_start() at the beginning of
+your web page, before your HTTP headers are sent. Then for every
+variable you want to keep alive for the duration of the session, call
+session_register($variable_name). By default, the session handler will
+keep track of the session by using a cookie. You can save objects or
+arrays in session variables also.
+
    
+
    The default method of storing sessions is to store it in a file.
+However if you have special needs such as you:
+
    
+
      
+  
    • Have multiple web servers that need to share session info
      • 
+  
    • Need to do special processing of each session
      • 
+  
    • Require notification when a session expires
      • 
+
    
+
    The ADOdb session handler provides you with the above
+additional capabilities by storing the session information as records
+in a database table that can be shared across multiple servers. 
    
+
    These records will be garbage collected based on the php.ini [session] timeout settings. 
+You can register a notification function to notify you when the record has expired and 
+is about to be freed by the garbage collector.
    
+
    An alternative to using a database backed session handler is to use memcached.
+  This is a distributed memory based caching system suitable for storing session
+  information.
+  
    
+
     The Improved Session Handler
    
+
    In ADOdb 4.91, we added a new session handler, in adodb-session2.php.
+It features the following improvements:
+
      
+
    • Fully supports server farms using a new database table format. The
+  previous version used the web server time for timestamps, which can cause problems
+  on a system with multiple web servers with possibly inconsistent
+  times. The new version uses the database server time instead for all timestamps.
+
    • The older database table format is obsolete. The database table must be modified
+  to support storage of the database server time mentioned above. Also the field
+  named DATA has been changed to SESSDATA. In some databases, DATA is a reserved
+  word.
+
    • The functions dataFieldName() and syncSeconds() is obsolete.
+
    
+
+
    Usage is 
+
+
    +include_once("adodb/session/adodb-session2.php");
+ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
+session_start();
+
+#
    # Test session vars, the following should increment on refresh
    #
    $_SESSION['AVAR'] += 1;
    print "<p>\$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";    
+
    
+
+
    When the session is created in session_start( ), the global variable $ADODB_SESS_CONN holds
+the connection object.
+
    The default name of the table is sessions2. If you want to override it:
+  
+
    +include_once("adodb/session/adodb-session2.php");
+$options['table'] = 'mytablename';
+ADOdb_Session::config($driver, $host, $user, $password, $database,$options);
+session_start();
+
    
+
+
+
    ADOdb Session Handler Features
    
+
      
+  
    • Ability to define a notification function that is called when a
+session expires. Typically
+used to detect session logout and release global resources. 
      • 
+  
    • Optimization of database writes. We crc32 the session data and
+only perform an update
+to the session data if there is a data change. 
      • 
+  
    • Support for large amounts of session data with CLOBs (see
+adodb-session-clob2.php). Useful
+for Oracle. 
      • 
+  
    • Support for encrypted session data, see
+adodb-cryptsession2.php. Enabling encryption is simply a matter of
+including adodb-cryptsession2.php instead of adodb-session2.php. 
      • 
+
    
+
    Session Handler Files 
    
+
    There are 3 session management files that you can use:
+
    
+
    adodb-session2.php        : The default
    adodb-cryptsession2.php   : Use this if you want to store encrypted session data in the database
    adodb-session-clob2.php   : Use this if you are storing DATA in clobs and you are NOT using oci8 driver
    
+
    Usage Examples
    
+
    To force non-persistent connections, call Persist() first before session_start():
+
+ 
+
    + 
+include_once("adodb/session/adodb-session2.php");
+$driver = 'mysql'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
+ADOdb_Session::config($driver, $host, $user, $password, $database, $options=false);
    ADOdb_session::Persist($connectMode=false);    
+session_start();
     
+
+# or, using DSN support so you can set other options such as port (since 5.11)
+include_once("adodb/session/adodb-session2.php");
+$dsn = 'mysql://root:pwd@localhost/mydb?persist=1&port=5654';
+ADOdb_Session::config($dsn, '', '', '');
+session_start();
+
    
+
     The parameter to the Persist( ) method sets the connection mode. You can
+  pass the following:
    
+
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+
    $connectModeConnection Method
    true
    PConnect( )
    falseConnect( )
    'N'NConnect( )
    'P'PConnect( )
    'C'Connect( )
    
+
    To use a encrypted sessions, simply replace the file adodb-session2.php:
    
+ 
     
    include('adodb/session/adodb-cryptsession2.php');
    $driver = 'mysql'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
+ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
    adodb_sess_open(false,false,$connectMode=false);    
+session_start();
    
+ 
    And the same technique for adodb-session-clob2.php:
    
+ 
      
    include('adodb/session/adodb-session2-clob2.php');
    $driver = 'oci8'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
+ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
    adodb_sess_open(false,false,$connectMode=false);    
+session_start();
    
+ 
    Installation
    
+
    1. Create this table in your database. Here is the MySQL version:
+
      
+CREATE TABLE sessions2(
+	  sesskey VARCHAR( 64 ) NOT NULL DEFAULT '',
+  	  expiry DATETIME NOT NULL ,
+	  expireref VARCHAR( 250 ) DEFAULT '',
+	  created DATETIME NOT NULL ,
+	  modified DATETIME NOT NULL ,
+	  sessdata LONGTEXT,
+	  PRIMARY KEY ( sesskey ) ,
+	  INDEX sess2_expiry( expiry ),
+	  INDEX sess2_expireref( expireref )
+)
    
+
+ 
     For PostgreSQL, use:
+ 
    CREATE TABLE sessions2(
+ sesskey VARCHAR( 64 ) NOT NULL DEFAULT '',
+ expiry TIMESTAMP NOT NULL ,
+ expireref VARCHAR( 250 ) DEFAULT '',
+ created TIMESTAMP NOT NULL ,
+ modified TIMESTAMP NOT NULL ,
+ sessdata TEXT DEFAULT '',
+ PRIMARY KEY ( sesskey )
+ );
+
    
+ 
    create INDEX sess2_expiry on sessions2( expiry );
+create INDEX sess2_expireref on sessions2 ( expireref );
    
+ 
    Here is the Oracle definition, which uses a CLOB for the SESSDATA field:
+ 
    +  CREATE TABLE SESSIONS2
    (
       SESSKEY    VARCHAR2(48 BYTE)                  NOT NULL,
       EXPIRY     DATE                               NOT NULL,
       EXPIREREF  VARCHAR2(200 BYTE),
       CREATED    DATE                               NOT NULL,
       MODIFIED   DATE                               NOT NULL,
       SESSDATA   CLOB,
      PRIMARY KEY(SESSKEY)
    );
+
    CREATE INDEX SESS2_EXPIRY ON SESSIONS2(EXPIRY);
+CREATE INDEX SESS2_EXPIREREF ON SESSIONS2(EXPIREREF);
    
+
     We need to use a CLOB here because for text greater than 4000 bytes long,
+  Oracle requires you to use the CLOB data type. If you are using the oci8 driver,
+  ADOdb will automatically enable CLOB handling. So you can use either adodb-session2.php
+  or adodb-session-clob2.php - in this case it doesn't matter. 
        
+
    Notifications
    
+
    You can receive notification when your session is cleaned up by the session garbage collector or
+when you call session_destroy().
+
    PHP's session extension will automatically run a special garbage collection function based on
+your php.ini session.cookie_lifetime and session.gc_probability settings. This will in turn call
+adodb's garbage collection function, which can be setup to do notification.
+
    
+
    +	PHP Session --> ADOdb Session  --> Find all recs  --> Send          --> Delete queued
+	GC Function     GC Function        to be deleted      notification      records
+	executed at     called by                             for all recs
+	random time     Session Extension                     queued for deletion
+
    
+
    When a session is created, we need to store a value in the session record (in the EXPIREREF field), typically 
+the userid of the session. Later when the session has expired,  just before the record is deleted,
+we reload the EXPIREREF field and call the notification function with the value of EXPIREREF, which 
+is the userid of the person being logged off.
+
    ADOdb uses a global variable $ADODB_SESSION_EXPIRE_NOTIFY that you must predefine before session
+start to store the notification configuration. 
+$ADODB_SESSION_EXPIRE_NOTIFY is an array with 2 elements, the
+first being the name of the session variable you would like to store in
+the EXPIREREF field, and the 2nd is the notification function's name. 
    
+
    For example, suppose we want to be notified when a user's session has expired,
+based on the userid. When the user logs in, we store the id in the global session variable
+$USERID. The function name is 'NotifyFn'. 
+
    
+So we define (before session_start() is called): 
    
+
     
+	$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
+
    
+And when the NotifyFn is called (when the session expires), the
+$EXPIREREF holding the user id is passed in as the first parameter, eg. NotifyFn($userid, $sesskey). The
+session key (which is the primary key of the record in the sessions
+table) is the 2nd parameter.
+
     Here is an example of a Notification function that deletes some
+records in the database and temporary files: 
    
+
    
+	function NotifyFn($expireref, $sesskey)
+	{
+		global $ADODB_SESS_CONN; # the session connection object
+		$user = $ADODB_SESS_CONN->qstr($expireref);
+		
+		$ADODB_SESS_CONN->Execute("delete from shopping_cart where user=$user");          
+		system("rm /work/tmpfiles/$expireref/*");
+	}  
+			  
    
+
     NOTE 1: If you have register_globals disabled in php.ini, then you
+will have to manually set the EXPIREREF. E.g. 
    
+
     
+$GLOBALS['USERID'] = GetUserID();
+$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
+
    
+
     NOTE 2: If you want to change the EXPIREREF after the session
+record has been created, you will need to modify any session variable
+to force a database record update.
+
    
+
    Neat Notification Tricks
    
+
    ExpireRef normally holds the user id of the current session.
+
    
+
    1. You can then write a session monitor, scanning expireref to see
+who is currently logged on.
+
    
+
    2. If you delete the sessions record for a specific user, eg.
+
    
+
    delete from sessions where expireref = '$USER'
    
+then the user is logged out. Useful for ejecting someone from a
+site.
+
    3. You can scan the sessions table to ensure no user
+can be logged in twice. Useful for security reasons.
+
    
+
    Compression/Encryption Schemes
    
+Since ADOdb 4.05, thanks to Ross Smith, multiple encryption and
+compression schemes are supported. Currently, supported are:
+
    
+
      MD5Crypt (crypt.inc.php)
      MCrypt
      Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)
      GZip
      BZip2
    
+
    These are stackable. E.g.
+
    ADODB_Session::filter(new ADODB_Compress_Bzip2());
    ADODB_Session::filter(new ADODB_Encrypt_MD5());
    
+will compress and then encrypt the record in the database.
+
    Session Cookie Regeneration: adodb_session_regenerate_id()
    
+
    Dynamically change the current session id with a newly generated one and update
+  database. Currently only works with cookies. Useful to improve security by
+  reducing the risk of session-hijacking. See this article on Session
+  Fixation for more info 
+on the theory behind this feature. Usage:
    +	include('path/to/adodb/session/adodb-session2.php');
+	
+	session_start();
+	# Approximately every 10 page loads, reset cookie for safety.
+	# This is extremely simplistic example, better 
+	# to regenerate only when the user logs in or changes
+	# user privilege levels.
+	if ((rand()%10) == 0) adodb_session_regenerate_id(); 
+
    
+
    This function calls session_regenerate_id() internally or simulates it if the function does not exist.
+
    Vacuum/Optimize Database
    
+
    During session garbage collection, if postgresql is detected,
+  ADOdb can be set to run VACUUM. If mysql is detected, then optimize database
+  could be called.You can turn this on or off using:
    
+
    $turnOn = true; # or false
+ADODB_Session::optimize($turnOn);
+
    
+
    The default  is optimization is disabled.
    
+
    Backwards Compatability 
    
+
    The older method of connecting to ADOdb using global variables is still supported:
    
+
     $ADODB_SESSION_DRIVER='mysql';
+ $ADODB_SESSION_CONNECT='localhost';
+ $ADODB_SESSION_USER ='root';
+ $ADODB_SESSION_PWD ='abc';
+ $ADODB_SESSION_DB ='phplens';
+ 
+ include('path/to/adodb/session/adodb-session2.php'); 
    
+
    In the above example, the only things you need to change in your code to upgrade
+  is 
    
+
      
+  
    • your session table format to the new one.
      • 
+  
    • the include file from adodb-session.php to adodb-session2.php. 
      • 
+
    
+

+
    Also see the core ADOdb documentation. And if
+  you are interested in the obsolete adodb-session.php, see old

    These records will be garbage collected based on the php.ini [session] timeout settings. 
+You can register a notification function to notify you when the record has expired and 
+is about to be freed by the garbage collector.
    
+
    Important Upgrade Notice: Since ADOdb 4.05, the session files
+have been moved to its own folder, adodb/session. This is a rewrite
+of the session code by Ross Smith. The old session code is in
+adodb/session/old. 
    
+
    ADOdb Session Handler Features
    
+
      
+  
    • Ability to define a notification function that is called when a
+session expires. Typically
+used to detect session logout and release global resources. 
      • 
+  
    • Optimization of database writes. We crc32 the session data and
+only perform an update
+to the session data if there is a data change. 
      • 
+  
    • Support for large amounts of session data with CLOBs (see
+adodb-session-clob.php). Useful
+for Oracle. 
      • 
+  
    • Support for encrypted session data, see
+adodb-cryptsession.php. Enabling encryption is simply a matter of
+including adodb-cryptsession.php instead of adodb-session.php. 
      • 
+
    
+
    Setup
    
+
    There are 3 session management files that you can use:
+
    
+
    adodb-session.php        : The default
    adodb-session-clob.php   : Use this if you are storing DATA in clobs
    adodb-cryptsession.php   : Use this if you want to store encrypted session data in the database

    
+
    
+
    Examples
+
    +     include('adodb/adodb.inc.php');
        
        $ADODB_SESSION_DRIVER='mysql';
        $ADODB_SESSION_CONNECT='localhost';
        $ADODB_SESSION_USER ='scott';
        $ADODB_SESSION_PWD ='tiger';
        $ADODB_SESSION_DB ='sessiondb';
        
        include('adodb/session/adodb-session.php');
        session_start();
        
        #
        # Test session vars, the following should increment on refresh
        #
        $_SESSION['AVAR'] += 1;
        print "<p>\$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";
    
+ 
+
    To force non-persistent connections, call adodb_session_open() first before session_start():
+
    
+ 
    + 
        include('adodb/adodb.inc.php');
        
        $ADODB_SESSION_DRIVER='mysql';
        $ADODB_SESSION_CONNECT='localhost';
        $ADODB_SESSION_USER ='scott';
        $ADODB_SESSION_PWD ='tiger';
        $ADODB_SESSION_DB ='sessiondb';
        
        include('adodb/session/adodb-session.php');
        adodb_sess_open(false,false,false);
        session_start();
         
+ 
    
+
     The 3rd parameter to adodb_sess_open($path, $sessname, $connectMode)  sets the connection method. You can pass in the following:
    
+
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+  
+    
+    
+  
+
    $connectModeConnection Method
    true
    PConnect( )
    falseConnect( )
    'N'NConnect( )
    'P'PConnect( )
    'C'Connect( )
    
+
    To use a encrypted sessions, simply replace the file adodb-session.php:
    
+ 
     
        include('adodb/adodb.inc.php');
        
        $ADODB_SESSION_DRIVER='mysql';
        $ADODB_SESSION_CONNECT='localhost';
        $ADODB_SESSION_USER ='scott';
        $ADODB_SESSION_PWD ='tiger';
        $ADODB_SESSION_DB ='sessiondb';
        
        include('adodb/session/adodb-cryptsession.php');
        session_start();
    
+ 
    
+ 
    And the same technique for adodb-session-clob.php:
    
+ 
      
        include('adodb/adodb.inc.php');
        
        $ADODB_SESSION_DRIVER='mysql';
        $ADODB_SESSION_CONNECT='localhost';
        $ADODB_SESSION_USER ='scott';
        $ADODB_SESSION_PWD ='tiger';
        $ADODB_SESSION_DB ='sessiondb';
        
        include('adodb/session/adodb-session-clob.php');
        session_start();    
+ 
    
+ 
    An alternative way to set persistant or non-persistent connections is to call the following function before session_start() is called.
+ 
    + 	ADODB_Session::persist('P'); # 'C' for non-persistent connections
+ 
    
+ 
    Installation
    
+
    1. Create this table in your database (MySQL syntax):
+
      
+   create table sessions (
+       SESSKEY char(32) not null,
+       EXPIRY int(11) unsigned not null,
+       EXPIREREF varchar(64),
+	   DATA text not null,
+	   primary key (sesskey)
+	   );
+ 
    
+
+ 
    You may want to rename the 'data' field to 'session_data' as
+	'data' appears to be a reserved word for one or more of the following:
+	
      
+	
    • 	ANSI SQL
+	
    • 	IBM DB2
+	
    • 	MS SQL Server
+	
    • 	Postgres
+	
    • 	SAP
+		
    
+
    
+	If you do, then execute:
+
    +		ADODB_Session::dataFieldName('session_data');
+
    
+ 
     For the adodb-session-clob.php version, create this:
+
      
    +    
        create table sessions (
           SESSKEY char(32) not null,
           EXPIRY int(11) unsigned not null,
           EXPIREREF varchar(64),
           DATA CLOB,
          primary key (sesskey)
      );    
+ 
    
+ 
    2. Then define the following parameters. You can either modify this file, or define them before this file is included:
+ 
          
        $ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
        $ADODB_SESSION_CONNECT='server to connect to';
        $ADODB_SESSION_USER ='user';
        $ADODB_SESSION_PWD ='password';
        $ADODB_SESSION_DB ='database';
        $ADODB_SESSION_TBL = 'sessions'; # setting this is optional
    	    
+ 
    
+     When the session is created, $ADODB_SESS_CONN holds the connection object.
        
      3. Recommended is PHP 4.0.6 or later. There are documented session bugs in earlier versions of PHP.
+
    Notifications
    
+
    You can receive notification when your session is cleaned up by the session garbage collector or
+when you call session_destroy().
+
    PHP's session extension will automatically run a special garbage collection function based on
+your php.ini session.cookie_lifetime and session.gc_probability settings. This will in turn call
+adodb's garbage collection function, which can be setup to do notification.
+
    
+
    +	PHP Session --> ADOdb Session  --> Find all recs  --> Send          --> Delete queued
+	GC Function     GC Function        to be deleted      notification      records
+	executed at     called by                             for all recs
+	random time     Session Extension                     queued for deletion
+
    
+
    When a session is created, we need to store a value in the session record (in the EXPIREREF field), typically 
+the userid of the session. Later when the session has expired,  just before the record is deleted,
+we reload the EXPIREREF field and call the notification function with the value of EXPIREREF, which 
+is the userid of the person being logged off.
+
    ADOdb uses a global variable $ADODB_SESSION_EXPIRE_NOTIFY that you must predefine before session
+start to store the notification configuration. 
+$ADODB_SESSION_EXPIRE_NOTIFY is an array with 2 elements, the
+first being the name of the session variable you would like to store in
+the EXPIREREF field, and the 2nd is the notification function's name. 
    
+
    For example, suppose we want to be notified when a user's session has expired,
+based on the userid. When the user logs in, we store the id in the global session variable
+$USERID. The function name is 'NotifyFn'. 
+
    
+So we define (before session_start() is called): 
    
+
     
+	$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
+
    
+And when the NotifyFn is called (when the session expires), the
+$USERID is passed in as the first parameter, eg. NotifyFn($userid, $sesskey). The
+session key (which is the primary key of the record in the sessions
+table) is the 2nd parameter.
+
     Here is an example of a Notification function that deletes some
+records in the database and temporary files: 
    
+
    
+	function NotifyFn($expireref, $sesskey)
+	{
+		global $ADODB_SESS_CONN; # the session connection object
+		$user = $ADODB_SESS_CONN->qstr($expireref);
+		
+		$ADODB_SESS_CONN->Execute("delete from shopping_cart where user=$user");          
+		system("rm /work/tmpfiles/$expireref/*");
+	}  
+			  
    
+
     NOTE 1: If you have register_globals disabled in php.ini, then you
+will have to manually set the EXPIREREF. E.g. 
    
+
     
+$GLOBALS['USERID'] = GetUserID();
+$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
+
    
+
     NOTE 2: If you want to change the EXPIREREF after the session
+record has been created, you will need to modify any session variable
+to force a database record update.
+
    
+
    Neat Notification Tricks
    
+
    ExpireRef normally holds the user id of the current session.
+
    
+
    1. You can then write a session monitor, scanning expireref to see
+who is currently logged on.
+
    
+
    2. If you delete the sessions record for a specific user, eg.
+
    
+
    delete from sessions where expireref = '$USER'
    
+then the user is logged out. Useful for ejecting someone from a
+site.
+
    3. You can scan the sessions table to ensure no user
+can be logged in twice. Useful for security reasons.
+
    
+
    Using Oracle CLOBs
    
+
    Suppose you are storing the DATA field in a CLOB:
+ 
    
+   CREATE TABLE sessions (
+       SESSKEY VARCHAR(32) NOT NULL,
+       EXPIRY NUMBER(16)  NOT NULL,
+       EXPIREREF VARCHAR(64),
+       DATA CLOB,
+      PRIMARY KEY (sesskey)
+  );
+ 
     
+ 
    Then your PHP code could look like this:
+	 
    +	ADODB_SESSION_DRIVER='oci8';
+	$ADODB_SESSION_CONNECT=$tnsname;
+	$ADODB_SESSION_USER ='scott';
+	$ADODB_SESSION_PWD = 'tiger';
+	$ADODB_SESSION_DB ='';
+	
+	$ADODB_SESSION_USE_LOBS = 'clob';
+	$ADODB_SESSION_TBL = 'sessions';
+	
+	$ADODB_SESS_DEBUG=0;
+	
+	include(ADODB_DIR.'/session/adodb-session.php');
+	
+	ADODB_Session::persist('P'); # use 'C' for non-persistent connects
+	
+	session_start();
+ 
    
+ 
    Note that you can set persistance using ADODB_Session::persist('P').
+ 
+
    Compression/Encryption Schemes
    
+Since ADOdb 4.05, thanks to Ross Smith, multiple encryption and
+compression schemes are supported. Currently, supported are:
+
    
+
      MD5Crypt (crypt.inc.php)
      MCrypt
      Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)
      GZip
      BZip2
    
+
    These are stackable. E.g.
+
    ADODB_Session::filter(new ADODB_Compress_Bzip2());
    ADODB_Session::filter(new ADODB_Encrypt_MD5());
    
+will compress and then encrypt the record in the database.
+
    adodb_session_regenerate_id()
    
+
    Dynamically change the current session id with a newly generated one and update database. Currently only
+works with cookies. Useful to improve security by reducing the risk of session-hijacking.
+See this article on Session Fixation for more info 
+on the theory behind this feature. Usage:
+
    +	$ADODB_SESSION_DRIVER='mysql';
+	$ADODB_SESSION_CONNECT='localhost';
+	$ADODB_SESSION_USER ='root';
+	$ADODB_SESSION_PWD ='abc';
+	$ADODB_SESSION_DB ='phplens';
+	
+	include('path/to/adodb/session/adodb-session.php');
+	
+	session_start();
+	# Every 10 page loads, reset cookie for safety.
+	# This is extremely simplistic example, better 
+	# to regenerate only when the user logs in or changes
+	# user privilege levels.
+	if ((rand()%10) == 0) adodb_session_regenerate_id(); 
+
    
+
    This function calls session_regenerate_id() internally or simulates it if the function does not exist.
+
    Vacuum/Optimize Database
    
+
    During session garbage collection, if postgresql is detected,
+  ADOdb can be set to run VACUUM. If mysql is detected, then optimize database
+  could be called.You can turn this on or off using:
    
+
    $turnOn = true; # or false
+ADODB_Session::optimize($turnOn);
+
    
+
    The default for optimization is it is disabled.
    
+

+
    The property $emptyDate missing from connection class. Also changed 1903 to 
+  constant (TIMESTAMP_FIRST_YEAR=100). Thx to Sebastiaan van Stijn. 
+
    ADOdb speedup optimization - we now return all arrays by reference. 
+
    Now DBDate() and DBTimeStamp() now accepts the string 'null' as a parameter. 
+  Suggested by vincent. 
+
    Added GetArray() to connection class. 
+
    Added not_null check in informix metacolumns(). 
+
    Connection parameters for postgresql did not work correctly when port was defined. 
+
    DB2 is now a tested driver, making adodb 100% compatible. Extensive changes 
+  to odbc driver for DB2, including implementing serverinfo() and SQLDate(), switching 
+  to SQL_CUR_USE_ODBC as the cursor mode, and lastAffectedRows and SelectLimit() 
+  fixes. 
+
    The odbc driver's FetchField() field names did not obey ADODB_ASSOC_CASE. Fixed.

    The odbc_mssql driver now sets CONCAT_NULL_YIELDS_NULL OFF for compat with 
+  mssql driver. 
+
    
+
+
    3.50 19 May 2003
    
+
    Fixed mssql compat with FreeTDS. FreeTDS does not implement mssql_fetch_assoc(). 
+
    Merged back connection and recordset code into adodb.inc.php. 
+
    ADOdb sessions using oracle clobs contributed by achim.gosse#ddd.de. See adodb-session-clob.php. 
+
    Added /s modifier to preg_match everywhere, which ensures that regex does not 
+  stop at /n. Thx Pao-Hsi Huang. 
+
    Fixed error in metacolumns() for mssql. 
+
    Added time format support for SQLDate. 
+
    Image => B added to metatype.

    MetaType now checks empty($this->blobSize) instead of empty($this). 
+
    Datadict has beta support for informix, sybase (mapped to mssql), db2 and generic 
+  (which is a fudge). 
+
    BlobEncode for postgresql uses pg_escape_bytea, if available. Needed for compat 
+  with 7.3. 
+
    Added $ADODB_LANG, to support multiple languages in MetaErrorMsg(). 
+
    Datadict can now parse table definition as declarative text. 
+
    For DataDict, oci8 autoincrement trigger missing semi-colon. Fixed. 
+
    For DataDict, when REPLACE flag enabled, drop sequence in datadict for autoincrement 
+  field in postgres and oci8.s 
+
    Postgresql defaults to template1 database if no database defined in connect/pconnect. 
+
    We now clear _resultid in postgresql if query fails. 
+
    3.40 19 May 2003
    
+
    Added insert_id for odbc_mssql. 
+
    Modified postgresql UpdateBlobFile() because it did not work in safe mode. 
+
    Now connection object is passed to raiseErrorFn as last parameter. Needed by 
+  StartTrans(). 
+
    Added StartTrans() and CompleteTrans(). It is recommended that you do not modify 
+  transOff, but use the above functions. 
+
    oci8po now obeys ADODB_ASSOC_CASE settings. 
+
    Added virtualized error codes, using PEAR DB equivalents. Requires you to manually 
+  include adodb-error.inc.php yourself, with MetaError() and MetaErrorMsg($errno). 
+
    GetRowAssoc for mysql and pgsql were flawed. Fix by Ross Smith. 
+
    Added to datadict types I1, I2, I4 and I8. Changed datadict type 'T' to map 
+  to timestamp instead of datetime for postgresql. 
+
    Error handling in ExecuteSQLArray(), adodb-datadict.inc.php did not work. 
+
    We now auto-quote postgresql connection parameters when building connection 
+  string. 
+
    Added session expiry notification. 
+
    We now test with odbc mysql - made some changes to odbc recordset constructor. 
+
    MetaColumns now special cases access and other databases for odbc. 
+
    3.31 17 March 2003
    
+
    Added row checking for _fetch in postgres. 
+
    Added Interval type to MetaType for postgres. 
+
    Remapped postgres driver to call postgres7 driver internally. 
+
    Adorecordset_array::getarray() did not return array when nRows >= 0. 
+
    Postgresql: at times, no error message returned by pg_result_error() but error 
+  message returned in pg_last_error(). Recoded again. 
+
    Interbase blob's now use chunking for updateblob. 
+
    Move() did not set EOF correctly. Reported by Jorma T. 
+
    We properly support mysql timestamp fields when we are creating mysql tables 
+  using the data-dict interface. 
+
    Table regex includes backticks character now. 
+
    3.30 3 March 2003
    
+
    Added $ADODB_EXTENSION and $ADODB_COMPAT_FETCH constant. 
+
    Made blank1stItem configurable using syntax "value:text" in GetMenu/GetMenu2. 
+  Thx to Gabriel Birke. 
+
    Previously ADOdb differed from the Microsoft standard because it did not define 
+  what to set $this->fields when EOF was reached. Now at EOF, ADOdb sets $this->fields 
+  to false for all databases, which is consist with Microsoft's implementation. 
+  Postgresql and mysql have always worked this way (in 3.11 and earlier). If you 
+  are experiencing compatibility problems (and you are not using postgresql nor 
+  mysql) on upgrading to 3.30, try setting the global variables $ADODB_COUNTRECS 
+  = true (which is the default) and $ADODB_FETCH_COMPAT = true (this is a new 
+  global variable). 
+
    We now check both pg_result_error and pg_last_error as sometimes pg_result_error 
+  does not display anything. Iman Mayes 
+
     We no longer check for magic quotes gpc in Quote(). 
+
     Misc fixes for table creation in adodb-datadict.inc.php. Thx to iamsure. 
+
     Time calculations use adodb_time library for all negative timestamps due to 
+  problems in Red Hat 7.3 or later. Formerly, only did this for Windows. 
+
     In mssqlpo, we now check if $sql in _query is a string before we change || 
+  to +. This is to support prepared stmts. 
+
     Move() and MoveLast() internals changed to support to support EOF and $this->fields 
+  change. 
+
     Added ADODB_FETCH_BOTH support to mssql. Thx to Angel Fradejas afradejas#mediafusion.es 
+
     We now check if link resource exists before we run mysql_escape_string in 
+  qstr(). 
+
     Before we flock in csv code, we check that it is not a http url. 
+
    3.20 17 Feb 2003
    
+
    Added new Data Dictionary classes for creating tables and indexes. Warning 
+  - this is very much alpha quality code. The API can still change. See adodb/tests/test-datadict.php 
+  for more info. 
+
    We now ignore $ADODB_COUNTRECS for mysql, because PHP truncates incomplete 
+  recordsets when mysql_unbuffered_query() is called a second time. 
+
    Now postgresql works correctly when $ADODB_COUNTRECS = false. 
+
    Changed _adodb_getcount to properly support SELECT DISTINCT. 
+
    Discovered that $ADODB_COUNTRECS=true has some problems with prepared queries 
+  - suspect PHP bug. 
+
    Now GetOne and GetRow run in $ADODB_COUNTRECS=false mode for better performance. 
+
    Added support for mysql_real_escape_string() and pg_escape_string() in qstr(). 
+
    Added an intermediate variable for mysql _fetch() and MoveNext() to store fields, 
+  to prevent overwriting field array with boolean when mysql_fetch_array() returns 
+  false. 
+
    Made arrays for getinsertsql and getupdatesql case-insensitive. Suggested by 
+  Tim Uckun" tim#diligence.com 
+
    3.11 11 Feb 2003
    
+
    Added check for ADODB_NEVER_PERSIST constant in PConnect(). If defined, then 
+  PConnect() will actually call non-persistent Connect(). 
+
    Modified interbase to properly work with Prepare(). 
+
    Added $this->ibase_timefmt to allow you to change the date and time format. 
+
    Added support for $input_array parameter in CacheFlush(). 
+
    Added experimental support for dbx, which was then removed when i found that 
+  it was slower than using native calls. 
+
    Added MetaPrimaryKeys for mssql and ibase/firebird. 
+
    Added new $trim parameter to GetCol and CacheGetCol 
+
    Uses updated adodb-time.inc.php 0.06. 
+
    3.10 27 Jan 2003 
+
    Added adodb_date(), adodb_getdate(), adodb_mktime() and adodb-time.inc.php. 
+
    For interbase, added code to handle unlimited number of bind parameters. From 
+  Daniel Hasan daniel#hasan.cl. 
+
    Added BlobDecode and UpdateBlob for informix. Thx to Fernando Ortiz. 
+
    Added constant ADODB_WINDOWS. If defined, means that running on Windows. 
+
    Added constant ADODB_PHPVER which stores php version as a hex num. Removed 
+  $ADODB_PHPVER variable. 
+
    Felho Bacsi reported a minor white-space regular expression problem in GetInsertSQL. 
+
    Modified ADO to use variant to store _affectedRows 
+
    Changed ibase to use base class Replace(). Modified base class Replace() to 
+  support ibase. 
+
    Changed odbc to auto-detect when 0 records returned is wrong due to bad odbc 
+  drivers. 
+
    Changed mssql to use datetimeconvert ini setting only when 4.30 or later (does 
+  not work in 4.23). 
+
    ExecuteCursor($stmt, $cursorname, $params) now accepts a new $params array 
+  of additional bind parameters -- William Lovaton walovaton#yahoo.com.mx. 
+
    Added support for sybase_unbuffered_query if ADODB_COUNTRECS == false. Thx 
+  to chuck may. 
+
    Fixed FetchNextObj() bug. Thx to Jorma Tuomainen. 
+
    We now use SCOPE_IDENTITY() instead of @@IDENTITY for mssql - thx to marchesini#eside.it 
+
    Changed postgresql movenext logic to prevent illegal row number from being 
+  passed to pg_fetch_array(). 
+
    Postgresql initrs bug found by "Bogdan RIPA" bripa#interakt.ro $f1 accidentally 
+  named $f 
+
    3.00 6 Jan 2003 
+
    Fixed adodb-pear.inc.php syntax error. 
+
    Improved _adodb_getcount() to use SELECT COUNT(*) FROM ($sql) for languages 
+  that accept it. 
+
    Fixed _adodb_getcount() caching error. 
+
    Added sql to retrive table and column info for odbc_mssql. 
+
    2.91 3 Jan 2003 
+
    Revised PHP version checking to use $ADODB_PHPVER with legal values 0x4000, 
+  0x4050, 0x4200, 0x4300. 
+
    Added support for bytea fields and oid blobs in postgres by allowing BlobDecode() 
+  to detect and convert non-oid fields. Also added BlobEncode to postgres when 
+  you want to encode oid blobs. 
+
    Added blobEncodeType property for connections to inform phpLens what encoding 
+  method to use for blobs. 
+
    Added BlobDecode() and BlobEncode() to base ADOConnection class. 
+
    Added umask() to _gencachename() when creating directories. 
+
    Added charPage for ado drivers, so you can set the code page. 
+
    +$conn->charPage = CP_UTF8;
+$conn->Connect($dsn);
+
    
+
    Modified _seek in mysql to check for num rows=0. 
+
    Added to metatypes new informix types for IDS 9.30. Thx Fernando Ortiz. 
+
    _maxrecordcount returned in CachePageExecute $rsreturn 
+
    Fixed sybase cacheselectlimit( ) problems 
+
    MetaColumns() max_length should use precision for types X and C for ms access. 
+  Fixed. 
+
    Speedup of odbc non-SELECT sql statements. 
+
    Added support in MetaColumns for Wide Char types for ODBC. We halve max_length 
+  if unicode/wide char. 
+
    Added 'B' to types handled by GetUpdateSQL/GetInsertSQL. 
+
    Fixed warning message in oci8 driver with $persist variable when using PConnect. 
+
    2.90 11 Dec 2002 
+
    Mssql and mssqlpo and oci8po now support ADODB_ASSOC_CASE. 
+
    Now MetaType() can accept a field object as the first parameter. 
+
    New $arr = $db->ServerInfo( ) function. Returns $arr['description'] which 
+  is the string description, and $arr['version']. 
+
    PostgreSQL and MSSQL speedups for insert/updates. 
+
     Implemented new SetFetchMode() that removes the need to use $ADODB_FETCH_MODE. 
+  Each connection has independant fetchMode. 
+
    ADODB_ASSOC_CASE now defaults to 2, use native defaults. This is because we 
+  would break backward compat for too many applications otherwise. 
+
    Patched encrypted sessions to use replace() 
+
    The qstr function supports quoting of nulls when escape character is \ 
+
    Rewrote bits and pieces of session code to check for time synch and improve 
+  reliability. 
+
    Added property ADOConnection::hasTransactions = true/false; 
+
    Added CreateSequence and DropSequence functions 
+
    Found misplaced MoveNext() in adodb-postgres.inc.php. Fixed. 
+
    Sybase SelectLimit not reliable because 'set rowcount' not cached - fixed. 
+
    Moved ADOConnection to adodb-connection.inc.php and ADORecordSet to adodb-recordset.inc.php. 
+  This allows us to use doxygen to generate documentation. Doxygen doesn't like 
+  the classes in the main adodb.inc.php file for some mysterious reason. 
+
    2.50, 14 Nov 2002 
+
    Added transOff and transCnt properties for disabling (transOff = true) and 
+  tracking transaction status (transCnt>0). 
+
    Added inputarray handling into _adodb_pageexecute_all_rows - "Ross Smith" RossSmith#bnw.com. 
+
    Fixed postgresql inconsistencies in date handling. 
+
    Added support for mssql_fetch_assoc. 
+
    Fixed $ADODB_FETCH_MODE bug in odbc MetaTables() and MetaPrimaryKeys(). 
+
    Accidentally declared UnixDate() twice, making adodb incompatible with php 
+  4.3.0. Fixed. 
+
    Fixed pager problems with some databases that returned -1 for _currentRow on 
+  MoveLast() by switching to MoveNext() in adodb-lib.inc.php. 
+
    Also fixed uninited $discard in adodb-lib.inc.php. 
+
    2.43, 25 Oct 2002
    
+Added ADODB_ASSOC_CASE constant to better support ibase and odbc field names. 
+
    Added support for NConnect() for oracle OCINLogin. 
+
    Fixed NumCols() bug. 
+
    Changed session handler to use Replace() on write. 
+
    Fixed oci8 SelectLimit aggregate function bug again. 
+
    Rewrote pivoting code. 
+
    2.42, 4 Oct 2002
    
+
    Fixed ibase_fetch() problem with nulls. Also interbase now does automatic blob 
+  decoding, and is backward compatible. Suggested by Heinz Hombergs heinz#hhombergs.de. 
+
    Fixed postgresql MoveNext() problems when called repeatedly after EOF. Also 
+  suggested by Heinz Hombergs. 
+
    PageExecute() does not rewrite queries if SELECT DISTINCT is used. Requested 
+  by hans#velum.net 
+
    Added additional fixes to oci8 SelectLimit handling with aggregate functions 
+  - thx to Christian Bugge for reporting the problem. 
+
    2.41, 2 Oct 2002
    
+
    Fixed ADODB_COUNTRECS bug in odbc. Thx to Joshua Zoshi jzoshi#hotmail.com. 
+
    Increased buffers for adodb-csvlib.inc.php for extremely long sql from 8192 
+  to 32000. 
+
    Revised pivottable.inc.php code. Added better support for aggregate fields. 
+
    Fixed mysql text/blob types problem in MetaTypes base class - thx to horacio 
+  degiorgi. 
+
    Added SQLDate($fmt,$date) function, which allows an sql date format string 
+  to be generated - useful for group by's. 
+
    Fixed bug in oci8 SelectLimit when offset>100. 
+
    2.40 4 Sept 2002
    
+
    Added new NLS_DATE_FORMAT property to oci8. Suggested by Laurent NAVARRO ln#altidev.com 
+
    Now use bind parameters in oci8 selectlimit for better performance. 
+
    Fixed interbase replaceQuote for dialect != 1. Thx to "BEGUIN Pierre-Henri 
+  - INFOCOB" phb#infocob.com. 
+
    Added white-space check to QA. 
+
    Changed unixtimestamp to support fractional seconds (we always round down/floor 
+  the seconds). Thanks to beezly#beezly.org.uk. 
+
    Now you can set the trigger_error type your own user-defined type in adodb-errorhandler.inc.php. 
+  Suggested by Claudio Bustos clbustos#entelchile.net. 
+
    Added recordset filters with rsfilter.inc.php. 
+
    $conn->_rs2rs does not create a new recordset when it detects it is of type 
+  array. Some trickery there as there seems to be a bug in Zend Engine 
+
    Added render_pagelinks to adodb-pager.inc.php. Code by "Pablo Costa" pablo#cbsp.com.br. 
+
    MetaType() speedup in adodb.inc.php by using hashing instead of switch. Best 
+  performance if constant arrays are supported, as they are in PHP5. 
+
    adodb-session.php now updates only the expiry date if the crc32 check indicates 
+  that the data has not been modified. 
+
    2.31 20 Aug 2002
    
+
    Made changes to pivottable.inc.php due to daniel lucuzaeu's suggestions (we sum the pivottable column if desired).
+
    Fixed ErrorNo() in postgres so it does not depend on _errorMsg property.
+
    Robert Tuttle added support for oracle cursors. See ExecuteCursor().
+
    Fixed Replace() so it works with mysql when updating record where data has not changed. Reported by
+Cal Evans (cal#calevans.com).
+
    2.30 1 Aug 2002
    
+
    Added pivottable.inc.php. Thanks to daniel.lucazeau#ajornet.com for the original 
+  concept.
+
    Added ADOConnection::outp($msg,$newline) to output error and debugging messages. Now 
+you can override this using the ADODB_OUTP constant and use your own output handler.
+
    Changed == to === for 'null' comparison. Reported by ericquil#yahoo.com 
+
    Fixed mssql SelectLimit( ) bug when distinct used.
+
    2.30 1 Aug 2002
    
+
    New GetCol() and CacheGetCol() from ross#bnw.com that returns the first field as a 1 dim array.
+
    We have an empty recordset, but RecordCount() could return -1. Fixed. Reported by  "Jonathan Polansky" jonathan#polansky.com.
+
    We now check for session variable changes using strlen($sessval).crc32($sessval). 
+Formerly we only used crc32().
+
    Informix SelectLimit() problem with $ADODB_COUNTRECS fixed.
+
    Fixed informix SELECT FIRST x DISTINCT, and not SELECT DISTINCT FIRST x - reported by F Riosa
+
    Now default adodb error handlers ignores error if @ used.
+
    If you set $conn->autoRollback=true, we auto-rollback persistent connections for odbc, mysql, oci8, mssql. 
+Default for autoRollback is false. No need to do so for postgres. 
+As interbase requires a transaction id (what a flawed api), we don't do it for interbase.
+
    Changed PageExecute() to use non-greedy preg_match when searching for "FROM" keyword.
+
    2.20 9 July 2002
    
+
    Added CacheGetOne($secs2cache,$sql), CacheGetRow($secs2cache,$sql), CacheGetAll($secs2cache,$sql).
+
    Added $conn->OffsetDate($dayFraction,$date=false) to generate sql that calcs 
+  date offsets. Useful for scheduling appointments.
+
    Added connection properties: leftOuter, rightOuter that hold left and right 
+  outer join operators.
+
    Added connection property: ansiOuter to indicate whether ansi outer joins supported.
+
    New driver mssqlpo, the portable mssql driver, which converts string 
+  concat operator from || to +.
+
    Fixed ms access bug - SelectLimit() did not support ties - fixed.
+
    Karsten Kraus (Karsten.Kraus#web.de), contributed error-handling code to ADONewConnection. 
+  Unfortunately due to backward compat problems, had to rollback most of the changes.
+
    Added new parameter to GetAssoc() to allow returning an array of key-value pairs, 
+ignoring any additional columns in the recordset. Off by default.
+
    Corrected mssql $conn->sysDate to return only date using convert().
+
    CacheExecute() improved debugging output.
+
    Changed rs2html() so newlines are converted to BR tags. Also optimized rs2html() based
+on feedback by "Jerry Workman" jerry#mtncad.com.
+
    Added support for Replace() with Interbase, using DELETE and INSERT.
+
    Some minor optimizations (mostly removing & references when passing arrays).
+
    Changed  GenID() to allows id's larger than the size of an integer.
+
    Added force_session property to oci8 for better updateblob() support.
+
    Fixed PageExecute() which did not work properly with sql containing GROUP BY.
+
    2.12 12 June 2002
    
+
    Added toexport.inc.php to export recordsets in CSV and tab-delimited format.
+
    CachePageExecute() does not work - fixed - thx John Huong.
+
    Interbase aliases not set properly in FetchField() - fixed. Thx Stefan Goethals.
+
    Added cache property to adodb pager class. The number of secs to cache recordsets.
+
    SQL rewriting bug in pageexecute() due to skipping of newlines due to missing /s modifier. Fixed.
+
    Max size of cached recordset due to a bug was 256000 bytes. Fixed.
+
    Speedup of 1st invocation of CacheExecute() by tuning code.
+
    We compare $rewritesql with $sql in pageexecute code in case of rewrite failure.
+
    2.11 7 June 2002
    
+
    Fixed PageExecute() rewrite sql problem - COUNT(*) and ORDER BY don't go together with
+	mssql, access and postgres. Thx to Alexander Zhukov alex#unipack.ru
+
    DB2 support for CHARACTER type added - thx John Huong huongch#bigfoot.com
+
    For ado, $argProvider not properly checked. Fixed - kalimero#ngi.it
+
    Added $conn->Replace() function for update with automatic insert if the record does not exist. 
+	Supported by all databases except interbase.
+
    2.10 4 June 2002
    
+
    Added uniqueSort property to indicate mssql ORDER BY cols must be unique.
+
    Optimized session handler by crc32 the data. We only write if session data has changed.
+
    adodb_sess_read in adodb-session.php now returns ''correctly - thanks to Jorma Tuomainen, webmaster#wizactive.com
+
    Mssql driver did not throw EXECUTE errors correctly because ErrorMsg() and ErrorNo() called in wrong order. 
+Pointed out by Alexios Fakos. Fixed.
+
    Changed ado to use client cursors. This fixes BeginTran() problems with ado.
+
    Added handling of timestamp type in ado.
+
    Added to ado_mssql support for insert_id() and affected_rows().
+
    Added support for mssql.datetimeconvert=0, available since php 4.2.0.
+
    Made UnixDate() less strict, so that the time is ignored if present.
+
    Changed quote() so that it checks for magic_quotes_gpc.
+
    Changed maxblobsize for odbc to default to 64000.
+
    2.00 13 May 2002
    
+
    Added drivers informix72 for pre-7.3 versions, and oci805 for 
+  oracle 8.0.5, and postgres64 for postgresql 6.4 and earlier. The postgres and postgres7 drivers
+  are now identical.
+
    Interbase now partially supports ADODB_FETCH_BOTH, by defaulting to ASSOC mode.
+
    Proper support for blobs in mssql. Also revised blob support code 
+is base class. Now UpdateBlobFile() calls UpdateBlob() for consistency.
+
    Added support for changed odbc_fetch_into api in php 4.2.0 
+with $conn->_has_stupid_odbc_fetch_api_change.
+
    Fixed spelling of tablock locking hint in GenID( ) for mssql. 
+
    Added RowLock( ) to several databases, including oci8, informix, sybase, etc. 
+  Fixed where error in mssql RowLock().
+
    Added sysDate and sysTimeStamp properties to most database drivers. These are the sql
+functions/constants for that database that return the current date and current timestamp, and 
+are useful for portable inserts and updates.
+
    Support for RecordCount() caused date handling in sybase and mssql to break. 
+Fixed, thanks to Toni Tunkkari, by creating derived classes for ADORecordSet_array for
+both databases. Generalized using arrayClass property. Also to support RecordCount(), 
+changed metatype handling for ado drivers. Now the type returned in FetchField 
+  is no longer a number, but the 1-char data type returned by MetaType.
+  At the same time, fixed a lot of date handling. Now mssql support dmy and mdy date formats. 
+Also speedups in sybase and mssql with preg_match and ^ in date/timestamp handling.
+Added support in sybase and mssql for 24 hour clock in timestamps (no AM/PM).
+
    Extensive revisions to informix driver - thanks to Samuel CARRIERE samuel_carriere#hotmail.com 
+
    Added $ok parameter to CommitTrans($ok) for easy rollbacks.
+
    Fixed odbc MetaColumns and MetaTables to save and restore $ADODB_FETCH_MODE.
+
    Some odbc drivers did not call the base connection class constructor. Fixed.
+
    Fixed regex for GetUpdateSQL() and GetInsertSQL() to support more legal character combinations.
+
+
    1.99 21 April 2002
    
+
    Added emulated RecordCount() to all database drivers if $ADODB_COUNTRECS = true 
+  (which it is by default). Inspired by Cristiano Duarte (cunha17#uol.com.br). 
+
    Unified stored procedure support for mssql and oci8. Parameter() and PrepareSP() 
+  functions implemented. 
+
    Added support for SELECT FIRST in informix, modified hasTop property to support 
+  this. 
+
    Changed csv driver to handle updates/deletes/inserts properly (when Execute() returns true).
+Bind params also work now, and raiseErrorFn with csv driver. Added csv driver to QA process. 
+
    Better error checking in oci8 UpdateBlob() and UpdateBlobFile().
+
    Added TIME type to MySQL - patch by Manfred h9125297#zechine.wu-wien.ac.at
+
    Prepare/Execute implemented for Interbase/Firebird 
+
    Changed some regular expressions to be anchored by /^ $/ for speed.
+
    Added UnixTimeStamp() and UnixDate() to ADOConnection(). Now these functions 
+  are in both ADOConnection and ADORecordSet classes.
+
    Empty recordsets were not cached - fixed.
+
    Thanks to Gaetano Giunta (g.giunta#libero.it) for the oci8 code review. We 
+  didn't agree on everything, but i hoped we agreed to disagree! 
+
    1.90 6 April 2002
    
+
    Now all database drivers support fetch modes ADODB_FETCH_NUM and ADODB_FETCH_ASSOC, though
+	still not fully tested. Eg. Frontbase, Sybase, Informix.

    NextRecordSet() support for mssql. Contributed by "Sven Axelsson" sven.axelsson#bokochwebb.se
+
    Added blob support for SQL Anywhere. Contributed by Wade Johnson wade#wadejohnson.de
+
    Fixed some security loopholes in server.php. Server.php also supports fetch mode.
+
    Generalized GenID() to support odbc and mssql drivers. Mssql no longer generates GUID's.
+
    Experimental RowLock($table,$where) for mssql.
+
    Properly implemented Prepare() in oci8 and ODBC.
+
    Added Bind() support to oci8 to support Prepare().
+
    Improved error handler. Catches CacheExecute() and GenID() errors now.
+
    Now if you are running php from the command line, debugging messages do not output html formating.
+Not 100% complete, but getting there.
+
    1.81 22 March 2002
    
+
    Restored default $ADODB_FETCH_MODE = ADODB_FETCH_DEFAULT for backward compatibility.
+
    SelectLimit for oci8 improved - Our FIRST_ROWS optimization now does not overwrite existing hint.
+
    New Sybase SQL Anywhere driver. Contributed by Wade Johnson wade#wadejohnson.de
+
    1.80 15 March 2002
    
+
    Redesigned directory structure of ADOdb files. Added new driver directory where
+all database drivers reside.
+
    Changed caching algorithm to create subdirectories. Now we scale better.
+
    Informix driver now supports insert_id(). Contribution by "Andrea Pinnisi" pinnisi#sysnet.it
+
    Added experimental ISO date and FetchField support for informix.
+
    Fixed a quoting bug in Execute() with bind parameters, causing problems with blobs.
+
    Mssql driver speedup by 10-15%.
+
    Now in CacheExecute($secs2cache,$sql,...), $secs2cache is optional. If missing, it will
+take the value defined in $connection->cacheSecs (default is 3600 seconds). Note that
+CacheSelectLimit(), the secs2cache is still compulsory - sigh.
+
    Sybase SQL Anywhere driver (using ODBC) contributed by Wade Johnson wade#wadejohnson.de
+
    1.72 8 March 2002
    
+
    Added @ when returning Fields() to prevent spurious error - "Michael William Miller" mille562#pilot.msu.edu
+
    MetaDatabases() for postgres contributed by Phil pamelant#nerim.net
+ 
    Mitchell T. Young (mitch#youngfamily.org) contributed informix driver.
+ 
    Fixed rs2html() problem. I cannot reproduce, so probably a problem with pre PHP 4.1.0 versions,
+  when supporting new ADODB_FETCH_MODEs.
+ 
    Mattia Rossi (mattia#technologist.com) contributed BlobDecode() and UpdateBlobFile() for postgresql
+ using the postgres specific pg_lo_import()/pg_lo_open() - i don't use them but hopefully others will
+ find this useful. See this posting
+ for an example of usage.
+ 
    Added UpdateBlobFile() for uploading files to a database.
+ 
    Made UpdateBlob() compatible with oci8po driver.
+ 
    Added noNullStrings support to oci8 driver. Oracle changes all ' ' strings to nulls,
+  so you need to set strings to ' ' to prevent the nullifying of strings. $conn->noNullStrings = true;
+  will do this for you automatically. This is useful when you define a char column as NOT NULL.
+  
    Fixed UnixTimeStamp() bug - wasn't setting minutes and seconds properly. Patch from Agusti Fita i Borrell agusti#anglatecnic.com.
+  
    Toni Tunkkari added patch for sybase dates. Problem with spaces in day part of date fixed.
+ 
    1.71 18 Jan 2002
    
+ 
    Sequence start id support. Now $conn->Gen_ID('seqname', 50) to start sequence from 50.
+ 
    CSV driver fix for selectlimit, from Andreas - akaiser#vocote.de.
+
    Gam3r spotted that a global variable was undefined in the session handler. 
+
    Mssql date regex had error. Fixed - reported by Minh Hoang vb_user#yahoo.com.
+
    DBTimeStamp() and DBDate() now accept iso dates and unix timestamps. This means
+that the PostgreSQL handling of dates in GetInsertSQL() and GetUpdateSQL() can
+be removed. Also if these functions are passed '' or null or false, we return a SQL null.
+
    GetInsertSQL() and GetUpdateSQL() now accept a new parameter, $magicq to 
+indicate whether quotes should be inserted based on magic quote settings - suggested by
+dj#4ict.com.
+
    Reformated docs slightly based on suggestions by Chris Small.
+ 
    1.65 28 Dec 2001
    
+ 
    Fixed borland_ibase class naming bug.
+ 
    Now instead of using $rs->fields[0] internally, we use reset($rs->fields) so 
+ that we are compatible with ADODB_FETCH_ASSOC mode. Reported by Nico S.
+ 
    Changed recordset constructor and _initrs() for oci8 so that it returns the field definitions even
+ if no rows in the recordset. Reported by Rick Hickerson (rhickers#mv.mv.com).
+ 
    Improved support for postgresql in GetInsertSQL and GetUpdateSQL by
+  "mike" mike#partner2partner.com  and "Ryan Bailey" rebel#windriders.com
+ 
    1.64 20 Dec 2001
    
+
    Danny Milosavljevic <danny.milo#gmx.net> added some patches for MySQL error handling
+and displaying default values.
+
    Fixed some ADODB_FETCH_BOTH inconsistencies in odbc and interbase.
+
    Added more tests to test suite to cover ADODB_FETCH_* and ADODB_ERROR_HANDLER.
+
    Added firebird (ibase) driver
+
    Added borland_ibase driver for interbase 6.5
+
    1.63 13 Dec 2001
    
+Absolute to the adodb-lib.inc.php file not set properly. Fixed.
    
+
+
    1.62 11 Dec 2001
    
+
    Major speedup of ADOdb for low-end web sites by reducing the php code loading and compiling
+cycle. We conditionally compile not so common functions. 
+Moved csv code to adodb-csvlib.inc.php to reduce adodb.inc.php parsing. This file
+is loaded only when the csv/proxy driver is used, or CacheExecute() is run.
+Also moved PageExecute(), GetSelectSQL() and GetUpdateSQL() core code to adodb-lib.inc.php.
+This reduced the 70K main adodb.inc.php file to 55K, and since at least 20K of the file
+is comments, we have reduced 50K of code in adodb.inc.php to 35K. There
+ should be 35% reduction in memory and thus 35% speedup in compiling the php code for the
+main adodb.inc.php file.
+
    Highly tuned SelectLimit() for oci8 for massive speed improvements on large files. 
+Selecting 20 rows starting from the 20,000th row of a table is now 7 times faster. 
+Thx to Tomas V V Cox.
+
    Allow . and # in table definitions in GetInsertSQL and GetUpdateSQL.
+ See ADODB_TABLE_REGEX constant. Thx to Ari Kuorikoski.
+
    Added ADODB_PREFETCH_ROWS constant, defaulting to 10. This determines the number
+of records to prefetch in a SELECT statement. Only used by oci8.
    
+
    Added high portability Oracle class called oci8po. This uses ? for bind variables, and 
+lower cases column names.
    
+
    Now all database drivers support $ADODB_FETCH_MODE, including interbase, ado, and odbc:
+ADODB_FETCH_NUM and ADODB_FETCH_ASSOC. ADODB_FETCH_BOTH is not fully implemented for all 
+database drivers.
+
    1.61 Nov 2001
    
+
    Added PO_RecordCount() and PO_Insert_ID(). PO stands for portable. Pablo Roca 
+  [pabloroca#mvps.org]
    
+
    GenID now returns 0 if not available. Safer is that you should check $conn->hasGenID 
+  for availability.
    
+
    M'soft ADO we now correctly close recordset in _close() peterd#telephonetics.co.uk
    
+
    MSSQL now supports GenID(). It generates a 16-byte GUID from mssql newid() 
+  function.
    
+
    Changed ereg_replace to preg_replace in SelectLimit. This is a fix for mssql. 
+  Ereg doesn't support t or n! Reported by marino Carlos xaplo#postnuke-espanol.org
    
+
    Added $recordset->connection. This is the ADOConnection object for the recordset. 
+Works with cached and normal recordsets. Surprisingly, this had no affect on performance!
    
+
    1.54 15 Nov 2001
    
+Fixed some more bugs in PageExecute().  I am getting sick of bug in this and will have to 
+reconsider my QA here. The main issue is that I don't use PageExecute() and 
+to check whether it is working requires a visual inspection of the html generated currently.
+It is possible to write a test script but it would be quite complicated :(
+
     More speedups of SelectLimit() for DB2, Oci8, access, vfp, mssql.
+
    
+
+
    1.53 7 Nov 2001
    
+Added support for ADODB_FETCH_ASSOC for ado and odbc drivers.
    
+Tuned GetRowAssoc(false) in postgresql and mysql.
    
+Stephen Van Dyke contributed ADOdb icon, accepted with some minor mods.
    
+Enabled Affected_Rows() for postgresql
    
+Speedup for Concat() using implode() - Benjamin Curtis ben_curtis#yahoo.com
    
+Fixed some more bugs in PageExecute() to prevent infinite loops
    
+
    1.52 5 Nov 2001
    
+Spelling error in CacheExecute() caused it to fail. $ql should be $sql in line 625!
    
+Added fixes for parsing [ and ] in GetUpdateSQL().
+
    1.51 5 Nov 2001
    
+
    Oci8 SelectLimit() speedup by using OCIFetch().
+
    Oci8 was mistakenly reporting errors when $db->debug = true.
+
    If a connection failed with ODBC, it was not correctly reported - fixed.
+
    _connectionID was inited to -1, changed to false.
+
    Added $rs->FetchRow(), to simplify API, ala PEAR DB
+
    Added PEAR DB compat mode, which is still faster than PEAR! See adodb-pear.inc.php.
+
    Removed postgres pconnect debugging statement.
+
    1.50 31 Oct 2001
    
+
    ADOdbConnection renamed to ADOConnection, and ADOdbFieldObject to ADOFieldObject.
+
    PageExecute() now checks for empty $rs correctly, and the errors in the docs on this subject have been fixed.
+
    odbc_error() does not return 6 digit error correctly at times. Implemented workaround.
+
    Added ADORecordSet_empty class. This will speedup INSERTS/DELETES/UPDATES because the return
+object created is much smaller.
+
    Added Prepare() to odbc, and oci8 (but doesn't work properly for oci8 still).
+
    Made pgsql a synonym for postgre7, and changed SELECT LIMIT to use OFFSET for compat with 
+postgres 7.2.
+
    Revised adodb-cryptsession.php thanks to Ari.
+
    Set resources to false on _close, to force freeing of resources.
+
    Added adodb-errorhandler.inc.php, adodb-errorpear.inc.php and raiseErrorFn on Freek's urging.
+
    GetRowAssoc($toUpper=true): $toUpper added as default.
+
    Errors when connecting to a database were not captured formerly. Now we do it correctly.
+
    1.40 19 September 2001
    
+
    PageExecute() to implement page scrolling added. Code and idea by Iván Oliva.
    
+
    Some minor postgresql fixes.
    
+
    Added sequence support using GenID() for postgresql, oci8, mysql, interbase.
    
+
    Added UpdateBlob support for interbase (untested).
    
+
    Added encrypted sessions (see adodb-cryptsession.php). By Ari Kuorikoski <kuoriari#finebyte.com>
    
+
    1.31 21 August 2001
    
+
    Many bug fixes thanks to "GaM3R (Cameron)" <gamr#outworld.cx>. Some session changes due to Gam3r.
+
    Fixed qstr() to quote  also.
+
    rs2html() now pretty printed.
+
    Jonathan Younger jyounger#unilab.com contributed the great idea GetUpdateSQL() and GetInsertSQL() which
+generates SQL to update and insert into a table from a recordset. Modify the recordset fields
+array, then can this function to generate the SQL (the SQL is not executed).
+
    "Nicola Fankhauser" <nicola.fankhauser#couniq.com> found some bugs in date handling for mssql.
    
+
    Added minimal Oracle support for LOBs. Still under development.
    
+Added $ADODB_FETCH_MODE so you can control whether recordsets return arrays which are
+numeric, associative or both. This is a global variable you set. Currently only MySQL, Oci8, Postgres
+drivers support this.
+
    PostgreSQL properly closes recordsets now. Reported by several people.
+
    
+Added UpdateBlob() for Oracle. A hack to make it easier to save blobs.
+
    
+Oracle timestamps did not display properly. Fixed.
+
    1.20 6 June 2001
    
+
    Now Oracle can connect using tnsnames.ora or server and service name
    
+
    Extensive Oci8 speed optimizations. 
+Oci8 code revised to support variable binding, and /*+ FIRST_ROWS */ hint.
    
+
    Worked around some 4.0.6 bugs in odbc_fetch_into().
    
+
    Paolo S. Asioli paolo.asioli#libero.it suggested GetRowAssoc().
    
+
    Escape quotes for oracle wrongly set to '. Now '' is used.
    
+
    Variable binding now works in ODBC also.
    
+
    Jumped to version 1.20 because I don't like 13 :-)
    
+
    1.12 6 June 2001
    
+
    Changed $ADODB_DIR to ADODB_DIR constant to plug a security loophole.
    
+
    Changed _close() to close persistent connections also. Prevents connection leaks.
    
+
    Major revision of oracle and oci8 drivers. 
+Added OCI_RETURN_NULLS and OCI_RETURN_LOBS to OCIFetchInto(). BLOB, CLOB and VARCHAR2 recognition
+in MetaType() improved. MetaColumns() returns columns in correct sort order.
    
+
    Interbase timestamp input format was wrong. Fixed.
    
+
    1.11 20 May 2001
    
+
    Improved file locking for Windows.
    
+
    Probabilistic flushing of cache to avoid avalanche updates when cache timeouts.
    
+
    Cached recordset timestamp not saved in some scenarios. Fixed.
    
+
    1.10 19 May 2001
    
+
    Added caching. CacheExecute() and CacheSelectLimit().
+
    Added csv driver. See http://php.weblogs.com/ADODB_csv. 
+
    Fixed SelectLimit(), SELECT TOP not working under certain circumstances.
+
    Added better Frontbase support of MetaTypes() by Frank M. Kromann.
+
    1.01 24 April 2001
    
+
    Fixed SelectLimit bug.  not quoted properly.
+
    SelectLimit: SELECT TOP -1 * FROM TABLE not support by Microsoft. Fixed.
    
+
    GetMenu improved by glen.davies#cce.ac.nz to support multiple hilited items
    
+
    FetchNextObject() did not work with only 1 record returned. Fixed bug reported by $tim#orotech.net
    
+
    Fixed mysql field max_length problem. Fix suggested by Jim Nicholson (jnich#att.com)
    
+
    1.00 16 April 2001
    
+
    Given some brilliant suggestions on how to simplify ADOdb by akul. You no longer need to
+setup $ADODB_DIR yourself, and ADOLoadCode() is automatically called by ADONewConnection(), 
+simplifying the startup code.
    
+
    FetchNextObject() added. Suggested by Jakub Marecek. This makes FetchObject() obsolete, as
+this is more flexible and powerful.
    
+
    Misc fixes to SelectLimit() to support Access (top must follow distinct) and Fields() 
+in the array recordset. From Reinhard Balling.
    
+
    0.96 27 Mar 2001
    
+
    ADOConnection Close() did not return a value correctly. Thanks to akul#otamedia.com.
    
+
    When the horrible magic_quotes is enabled, back-slash () is changed to double-backslash (\).
+This doesn't make sense for Microsoft/Sybase databases. We fix this in qstr().
    
+
    Fixed Sybase date problem in UnixDate() thanks to Toni Tunkkari. Also fixed MSSQL problem
+in UnixDate() - thanks to milhouse31#hotmail.com.
    
+
    MoveNext() moved to leaf classes for speed in MySQL/PostgreSQL. 10-15% speedup.
    
+
    Added null handling in bindInputArray in Execute() -- Ron Baldwin suggestion.
    
+
    Fixed some option tags. Thanks to john#jrmstudios.com.

    Added SelectLimit to ADOConnection to simulate PostgreSQL's "select * from table limit 10 offset 3".
+Added helper function GetArrayLimit() to ADORecordSet.
    
+
    Fixed mysql metacolumns bug. Thanks to Freek Dijkstra (phpeverywhere#macfreek.com).
    
+
    Also many PostgreSQL changes by Freek. He almost rewrote the whole PostgreSQL driver!
    
+
    Added fix to input parameters in Execute for non-strings by Ron Baldwin.
    
+
    Added new metatype, X for TeXt. Formerly, metatype B for Blob also included
+text fields. Now 'B' is for binary/image data. 'X' for textual data.
    
+
    Fixed $this->GetArray() in GetRows().
    
+
    Oracle and OCI8: 1st parameter is always blank -- now warns if it is filled.
    
+
    Now hasLimit and hasTop added to indicate whether 
+SELECT * FROM TABLE LIMIT 10 or SELECT TOP 10 * FROM TABLE are supported.
    
+
    0.94 04 Feb 2001
    
+
    Added ADORecordSet::GetRows() for compatibility with Microsoft ADO. Synonym for GetArray().

+
    Added ADORecordSet.FetchObject() to return a row as an object.
    
+
    Finally got a Linux box to test PostgreSql. Many fixes.
    
+
    Fixed copyright misspellings in 0.93.
    
+
    Fixed mssql MetaColumns type bug.
    
+
    Worked around odbc bug in PHP4 for sessions.

+
    Added arr2html() to convert array to html table.
    
+
    0.92 2 Jan 2002
    
+
    Interbase Commit and Rollback should be working again.
    
+
    Changed initialisation of ADORecordSet. This is internal and should not affect users. We
+are doing this to support cached recordsets in the future.
    
+
+
    Implemented ADORecordSet_array class. This allows you to simulate a database recordset
+with an array.
    
+
    Added UnixDate() and UnixTimeStamp() to ADORecordSet.
    
+
    0.91 21 Dec 2000
    
+
    Fixed ODBC so ErrorMsg() is working.
    
+
    Worked around ADO unrecognised null (0x1) value problem in COM.
    
+

+
    Now ODBC downloads first 8K of blob by default
+
    0.90 15 Nov 2000
    
+
    Lots of testing of Microsoft ADO. Should be more stable now.
    
+
    Added $ADODB_COUNTREC. Set to false for high speed selects.
    
+
    Added Sybase support. Contributed by Toni Tunkkari (toni.tunkkari#finebyte.com). Bug in Sybase 
+  API: GetFields is unable to determine date types.
    
+
    Changed behaviour of RecordSet.GetMenu() to support size parameter (listbox) properly.
    
+
    Added emptyDate and emptyTimeStamp to RecordSet class that defines how to represent

+
    Added MetaColumns($table) that returns an array of ADOFieldObject's listing 
+  the columns of a table.
    
+
    Added transaction support for PostgresSQL -- thanks to "Eric G. Werk" egw#netguide.dk.
    
+
    Added adodb-session.php for session support.
    
+
    0.80 30 Nov 2000

+  PostgreSQL more extensively tested.
    
+
    0.71 22 Nov 2000
    
+
    Switched from using require_once to include/include_once for backward compatability with PHP 4.02 and earlier.
    
+
    0.70 15 Nov 2000
    
+
    Calls by reference have been removed (call_time_pass_reference=Off) to ensure compatibility with future versions of PHP, 
+except in Oracle 7 driver due to a bug in php_oracle.dll.
    
+
    PostgreSQL database driver contributed by Alberto Cerezal (acerezalp#dbnet.es). 
+
    
+
    Oci8 driver for Oracle 8 contributed by George Fourlanos (fou#infomap.gr).
    
+
    Added mysqlt database driver to support MySQL 3.23 which has transaction 
+ support. 
    
+
    Oracle default date format (DD-MON-YY) did not match ADOdb default date format (which is YYYY-MM-DD). Use ALTER SESSION to force the default date.
    
+
    Error message checking is now included in test suite.
    
+
    MoveNext() did not check EOF properly -- fixed.
    
+

    Fixed some interbase bugs.
    
+
    0.50 Oct 16 2000
    
+
    Interbase commit/rollback changed to be compatible with PHP 4.03. 
    
+
    CommitTrans( ) will now return true if transactions not supported. 
    
+
    Conversely RollbackTrans( ) will return false if transactions not supported. 
+
    
+
    0.46 Oct 12
    
+Many Oracle compatibility issues fixed. 
+
    0.40 Sept 26
    
+
    Many bug fixes
    
+
    Now Code for BeginTrans, CommitTrans and RollbackTrans is working. So is the Affected_Rows
+and Insert_ID. Added above functions to test.php.
    
+
    ADO type handling was busted in 0.30. Fixed.
    
+
    Generalised Move( ) so it works will all databases, including ODBC.
    
+
    0.30 Sept 18
    
+
    Renamed ADOLoadDB to ADOLoadCode. This is clearer.
    
+
    Added BeginTrans, CommitTrans and RollbackTrans functions.
    
+
    Added Affected_Rows() and Insert_ID(), _affectedrows() and _insertID(), ListTables(),

+
    Added support for Microsoft's ADO.
    
+
    Added new field to ADORecordSet -- canSeek
    
+
    Added new parameter to _fetch($ignore_fields = false). Setting to true will 
+ not update fields array for faster performance.
    
+
    Added new field to ADORecordSet/ADOConnection -- dataProvider to indicate whether 
+ a class is derived from odbc or ado.
    
+

    ADOdb Library for PHP
    
+
    ADOdb is a suite of database libraries that allow you to connect to multiple 
+	databases in a portable manner. Download from http://adodb.sourceforge.net/.
+
    • The ADOdb documentation has moved to docs-adodb.htm 
+	This allows you to query, update and insert records using a portable API.
+
    • The ADOdb data dictionary docs are at docs-datadict.htm. 
+	This allows you to create database tables and indexes in a portable manner.
+
    • The ADOdb database performance monitoring docs are at docs-perf.htm. 
+	This allows you to perform health checks, tune and monitor your database.
+
    • The ADOdb database-backed session docs are at docs-session.htm. 
+
    
+
    
+
    Installation
    
+Make sure you are running PHP4.0.4 or later. Unpack all the files into a directory accessible by your webserver.
+
    
+To test, try modifying some of the tutorial examples. Make sure you customize the connection settings correctly. You can debug using:
+
    +<?php
+include('adodb/adodb.inc.php');
+
+$db = ADONewConnection($driver); # eg. 'mysql' or 'oci8' 
+$db->debug = true;
+$db->Connect($server, $user, $password, $database);
+$rs = $db->Execute('select * from some_small_table');
+print "<pre>";
+print_r($rs->GetRows());
+print "</pre>";
+?>
+

    Tips on Writing Portable SQL  
    		
+ 
    
+  
    Updated 6 Oct 2006. Added OffsetDate example.
+  
    Updated 18 Sep 2003. Added Portable Native SQL section.
+
    
+
+ If you are writing an application that is used in multiple environments and 
+  operating systems, you need to plan to support multiple databases. This article 
+  is based on my experiences with multiple database systems, stretching from 4th 
+  Dimension in my Mac days, to the databases I currently use, which are: Oracle, 
+  FoxPro, Access, MS SQL Server and MySQL. Although most of the advice here applies 
+  to using SQL with Perl, Python and other programming languages, I will focus on PHP and how 
+  the ADOdb database abstraction library 
+  offers some solutions.
    
+
    Most database vendors practice product lock-in. The best or fastest way to 
+  do things is often implemented using proprietary extensions to SQL. This makes 
+  it extremely hard to write portable SQL code that performs well under all conditions. 
+  When the first ANSI committee got together in 1984 to standardize SQL, the database 
+  vendors had such different implementations that they could only agree on the 
+  core functionality of SQL. Many important application specific requirements 
+  were not standardized, and after so many years since the ANSI effort began, 
+  it looks as if much useful database functionality will never be standardized. 
+  Even though ANSI-92 SQL has codified much more, we still have to implement portability 
+  at the application level.
    
+
    Selects
    
+
    The SELECT statement has been standardized to a great degree. Nearly every 
+  database supports the following:
    
+
    SELECT [cols] FROM [tables]
    
+    [WHERE conditions]
    
+    [GROUP BY cols]
    
+    [HAVING conditions] 
    
+    [ORDER BY cols]
    
+
    But so many useful techniques can only be implemented by using proprietary 
+  extensions. For example, when writing SQL to retrieve the first 10 rows for 
+  paging, you could write...
    
+
+   
+	
+	
+  
+   
+	
+	
+  
+   
+	
+	
+  
+   
+	
+	
+  
+   
+	
+	
+  
+   
+	
+	
+  
+
    DatabaseSQL Syntax
    DB2select * from table fetch first 10 rows only
    Informixselect first 10 * from table
    Microsoft SQL Server and Accessselect top 10 * from table
    MySQL and PostgreSQLselect * from table limit 10
    Oracle 8iselect * from (select * from table) where rownum <= 10
    
+
    This feature of getting a subset of data is so useful that in the PHP class 
+  library ADOdb, we have a SelectLimit( ) function that allows you to hide the 
+  implementation details within a function that will rewrite your SQL for you:
    
+
    $connection->SelectLimit('select * from table', 10);
+
    
+
    Selects: Fetch Modes
    
+
    PHP allows you to retrieve database records as arrays. You can choose to have 
+  the arrays indexed by field name or number. However different low-level PHP 
+  database drivers are inconsistent in their indexing efforts. ADOdb allows you 
+  to determine your prefered mode. You set this by setting the variable $ADODB_FETCH_MODE 
+  to either of the constants ADODB_FETCH_NUM (for numeric indexes) or ADODB_FETCH_ASSOC 
+  (using field names as an associative index).
    
+
    The default behaviour of ADOdb varies depending on the database you are using. 
+  For consistency, set the fetch mode to either ADODB_FETCH_NUM (for speed) or 
+  ADODB_FETCH_ASSOC (for convenience) at the beginning of your code. 
    
+
    Selects: Counting Records
    
+
    Another problem with SELECTs is that some databases do not return the number 
+  of rows retrieved from a select statement. This is because the highest performance 
+  databases will return records to you even before the last record has been found. 
+
    
+
    In ADOdb, RecordCount( ) returns the number of rows returned, or will emulate 
+  it by buffering the rows and returning the count after all rows have been returned. 
+  This can be disabled for performance reasons when retrieving large recordsets 
+  by setting the global variable $ADODB_COUNTRECS = false. This variable is checked 
+  every time a query is executed, so you can selectively choose which recordsets 
+  to count.
    
+
    If you prefer to set $ADODB_COUNTRECS = false, ADOdb still has the PO_RecordCount( 
+  ) function. This will return the number of rows, or if it is not found, it will 
+  return an estimate using SELECT COUNT(*):
    
+
    $rs = $db->Execute("select * from table where state=$state");
+$numrows = $rs->PO_RecordCount('table', "state=$state");
    
+
    Selects: Locking 
    
+
    SELECT statements are commonly used to implement row-level locking of tables. 
+  Other databases such as Oracle, Interbase, PostgreSQL and MySQL with InnoDB 
+  do not require row-level locking because they use versioning to display data 
+  consistent with a specific point in time.
    
+
    Currently, I recommend encapsulating the row-level locking in a separate function, 
+  such as RowLock($table, $where):
    
+
    $connection->BeginTrans( );
+$connection->RowLock($table, $where); 
    
+
    # some operation
    
+
    if ($ok) $connection->CommitTrans( );
+else $connection->RollbackTrans( );
+
    
+
    Selects: Outer Joins
    
+
    Not all databases support outer joins. Furthermore the syntax for outer joins 
+  differs dramatically between database vendors. One portable (and possibly slower) 
+  method of implementing outer joins is using UNION.
    
+
    For example, an ANSI-92 left outer join between two tables t1 and t2 could 
+  look like:
    
+
    SELECT t1.col1, t1.col2, t2.cola 
      FROM t1 LEFT JOIN t2 ON t1.col = t2.col
    
+
    This can be emulated using:
    
+
    SELECT t1.col1, t1.col2, t2.cola FROM t1, t2 
    	   WHERE t1.col = t2.col 
+   UNION ALL
+SELECT col1, col2, null FROM t1 
    	   WHERE t1.col not in (select distinct col from t2)
+
    
+
    Since ADOdb 2.13, we provide some hints in the connection object as to legal 
+  join variations. This is still incomplete and sometimes depends on the database 
+  version you are using, but is useful as a general guideline:
    
+
    $conn->leftOuter: holds the 
+  operator used for left outer joins (eg. '*='), or false if not known or not 
+  available.
    
+  $conn->rightOuter: holds the 
+  operator used for right outer joins (eg '=*'), or false if not known or not 
+  available.
    
+  $conn->ansiOuter: boolean 
+  that if true means that ANSI-92 style outer joins are supported, or false if 
+  not known.
    
+
    Inserts 
    
+
    When you create records, you need to generate unique id's for each record. 
+  There are two common techniques: (1) auto-incrementing columns and (2) sequences. 
+
    
+
    Auto-incrementing columns are supported by MySQL, Sybase and Microsoft Access 
+  and SQL Server. However most other databases do not support this feature. So 
+  for portability, you have little choice but to use sequences. Sequences are 
+  special functions that return a unique incrementing number every time you call 
+  it, suitable to be used as database keys. In ADOdb, we use the GenID( ) function. 
+  It has takes a parameter, the sequence name. Different tables can have different 
+  sequences. 
    
+
    $id = $connection->GenID('sequence_name');
    $connection->Execute("insert into table (id, firstname, lastname) 
    			   values ($id, $firstname, $lastname)");
    
+
    For databases that do not support sequences natively, ADOdb emulates sequences 
+  by creating a table for every sequence.
    
+
    Binding
    
+
    Binding variables in an SQL statement is another tricky feature. Binding is 
+  useful because it allows pre-compilation of SQL. When inserting multiple records 
+  into a database in a loop, binding can offer a 50% (or greater) speedup. However 
+  many databases such as Access and MySQL do not support binding natively and 
+  there is some overhead in emulating binding. Furthermore, different databases 
+  (specificly Oracle!) implement binding differently. My recommendation is to 
+  use binding if your database queries are too slow, but make sure you are using 
+  a database that supports it like Oracle. 
    
+
    ADOdb supports portable Prepare/Execute with:
    
+
    $stmt = $db->Prepare('select * from customers where custid=? and state=?');
+$rs = $db->Execute($stmt, array($id,'New York'));
    
+
    Oracle uses named bind placeholders, not "?", so to support portable binding, we have Param() that generates 
+the correct placeholder (available since ADOdb 3.92):
+
    $sql = 'insert into table (col1,col2) values ('.$DB->Param('a').','.$DB->Param('b').')';
+# generates 'insert into table (col1,col2) values (?,?)'
+# or        'insert into table (col1,col2) values (:a,:b)'
+$stmt = $DB->Prepare($sql);
+$stmt = $DB->Execute($stmt,array('one','two'));
+
    
+
+
    Portable Native SQL
    
+
    ADOdb provides the following functions for portably generating SQL functions 
+  as strings to be merged into your SQL statements (some are only available since 
+  ADOdb 3.92): 
    
+
+

+
    $db->substrProperty that holds the name of the SQL substring function.
+
    
+
      
    
+
    DDL and Tuning
    
+There are database design tools such as ERWin or Dezign that allow you to generate data definition language commands such as ALTER TABLE or CREATE INDEX from Entity-Relationship diagrams. 
+
    
+However if you prefer to use a PHP-based table creation scheme, adodb provides you with this feature. Here is the code to generate the SQL to create a table with: 
+
      
+	
    1.  Auto-increment primary key 'ID', 
      2. 
+	
    2. The person's 'NAME' VARCHAR(32) NOT NULL and defaults to '', 
      3. 
+	
    3. The date and time of record creation 'CREATED', 
      4. 
+	
    4.  The person's 'AGE', defaulting to 0, type NUMERIC(16). 
      5. 
+
    
+
    
+Also create a compound index consisting of 'NAME' and 'AGE': 
+
    +$datadict = NewDataDictionary($connection);
+$flds = " 
+  ID I AUTOINCREMENT PRIMARY,
+  NAME C(32) DEFAULT '' NOTNULL,
+  CREATED T DEFTIMESTAMP,
+  AGE N(16) DEFAULT 0
+";
+$sql1 = $datadict->CreateTableSQL('tabname', $flds);
+$sql2 = $datadict->CreateIndexSQL('idx_name_age', 'tabname', 'NAME,AGE');
+
    
+
+
    Data Types
    
+
    Stick to a few data types that are available in most databases. Char, varchar 
+  and numeric/number are supported by most databases. Most other data types (including 
+  integer, boolean and float) cannot be relied on being available. I recommend 
+  using char(1) or number(1) to hold booleans. 
    
+
    Different databases have different ways of representing dates and timestamps/datetime. 
+  ADOdb attempts to display all dates in ISO (YYYY-MM-DD) format. ADOdb also provides 
+  DBDate( ) and DBTimeStamp( ) to convert dates to formats that are acceptable 
+  to that database. Both functions accept Unix integer timestamps and date strings 
+  in ISO format.
    
+
    $date1 = $connection->DBDate(time( ));
    $date2 = $connection->DBTimeStamp('2002-02-23 13:03:33');
    
+
    We also provide functions to convert database dates to Unix timestamps:
    
+
    $unixts = $recordset->UnixDate('#2002-02-30#'); # MS Access date =gt; unix timestamp
    
+
    For date calculations, we have OffsetDate which allows you to calculate dates such as yesterday and next week in a RDBMS independant fashion. For example, if we want to set a field to 6 hour from now, use:
+
    +$sql = 'update table set dtimefld='.$db->OffsetDate($db->sysTimeStamp, 6/24).' where ...';
+
    
+
    The maximum length of a char/varchar field is also database specific. You can 
+  only assume that field lengths of up to 250 characters are supported. This is 
+  normally impractical for web based forum or content management systems. You 
+  will need to be familiar with how databases handle large objects (LOBs). ADOdb 
+  implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to 
+  update fields holding Binary Large Objects (eg. pictures) and Character Large 
+  Objects (eg. HTML articles):
    
+
    # for oracle 
+$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1,empty_blob())'); 
+$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1'); 
+   
+# non-oracle databases
+$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)'); 
+$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
+
    
+
    Null handling is another area where differences can occur. This is a mine-field, 
+  because 3-value logic is tricky.
+
    In general, I avoid using nulls except for dates and default all my numeric 
+  and character fields to 0 or the empty string. This maintains consistency with 
+  PHP, where empty strings and zero are treated as equivalent, and avoids SQL 
+  ambiguities when you use the ANY and EXISTS operators. However if your database 
+  has significant amounts of missing or unknown data, using nulls might be a good 
+  idea. 
+  
    
+  ADOdb also supports a portable IfNull function, so you can define what to display
+  if the field contains a null.
+
    Stored Procedures
    
+
    Stored procedures are another problem area. Some databases allow recordsets 
+  to be returned in a stored procedure (Microsoft SQL Server and Sybase), and 
+  others only allow output parameters to be returned. Stored procedures sometimes 
+  need to be wrapped in special syntax. For example, Oracle requires such code 
+  to be wrapped in an anonymous block with BEGIN and END. Also internal sql operators 
+  and functions such as +, ||, TRIM( ), SUBSTR( ) or INSTR( ) vary between vendors. 
+
    
+
    An example of how to call a stored procedure with 2 parameters and 1 return 
+  value follows:
    
+
    	switch ($db->databaseType) {
+	case 'mssql':
+	  $sql = 'SP_RUNSOMETHING'; break;
+	case 'oci8':
+	  $sql = 
+	  "declare RETVAL integer;begin :RETVAL := SP_RUNSOMETHING(:myid,:group);end;";
+	  break;
+	default:
+	  die('Unsupported feature');
+	}
+	# @RETVAL = SP_RUNSOMETHING @myid,@group
+	$stmt = $db->PrepareSP($sql);	
    	$db->Parameter($stmt,$id,'myid'); 
+	$db->Parameter($stmt,$group,'group');
+	# true indicates output parameter
    	    $db->Parameter($stmt,$ret,'RETVAL',true); 
+	$db->Execute($stmt); 
    
+
    As you can see, the ADOdb API is the same for both databases. But the stored 
+  procedure SQL syntax is quite different between databases and is not portable, 
+  so be forewarned! However sometimes you have little choice as some systems only 
+  allow data to be accessed via stored procedures. This is when the ultimate portability 
+  solution might be the only solution: treating portable SQL as a localization 
+  exercise...
    
+
    SQL as a Localization Exercise
    
+
     In general to provide real portability, you will have to treat SQL coding 
+  as a localization exercise. In PHP, it has become common to define separate 
+  language files for English, Russian, Korean, etc. Similarly, I would suggest 
+  you have separate Sybase, Intebase, MySQL, etc files, and conditionally include 
+  the SQL based on the database. For example, each MySQL SQL statement would be 
+  stored in a separate variable, in a file called 'mysql-lang.inc.php'.
    
+
    $sqlGetPassword = 'select password from users where userid=%s';
+$sqlSearchKeyword = quot;SELECT * FROM articles WHERE match (title,body) against (%s)";
    
+
    In our main PHP file:
    
+
    # define which database to load...
+$database = 'mysql';
+include_once("$database-lang.inc.php");
+
+$db = NewADOConnection($database);
+$db->PConnect(...) or die('Failed to connect to database');
+
+# search for a keyword $word
+$rs = $db->Execute(sprintf($sqlSearchKeyWord,$db->qstr($word)));
    
+
    Note that we quote the $word variable using the qstr( ) function. This is because 
+  each database quotes strings using different conventions.
    
+
    
+
    Final Thoughts
    
+
    The best way to ensure that you have portable SQL is to have your data tables designed using 
+sound principles. Learn the theory of normalization and entity-relationship diagrams and model 
+your data carefully. Understand how joins and indexes work and how they are used to tune performance.
+

+  http://php.weblogs.com/sql_tutorial.

    I love this song, especially the version with Louis Armstrong and Ella singing 
+  duet. It is all about how hard it is for two people in love to be compatible 
+  with each other. It's about compromise and finding a common ground, and that's 
+  what this article is all about. 
+
    PHP is all about creating dynamic web-sites with the least fuss and the most 
+  fun. To create these websites we need to use databases to retrieve login information, 
+  to splash dynamic news onto the web page and store forum postings. So let's 
+  say we were using the popular MySQL database for this. Your company has done 
+  such a fantastic job that the Web site is more popular than your wildest dreams. 
+  You find that MySQL cannot scale to handle the workload; time to switch databases. 
+
     Unfortunately in PHP every database is accessed slightly differently. To connect 
+  to MySQL, you would use mysql_connect(); when you decide to upgrade to 
+  Oracle or Microsoft SQL Server, you would use ocilogon() or mssql_connect() 
+  respectively. What is worse is that the parameters you use for the different 
+  connect functions are different also.. One database says po-tato, the other 
+  database says pota-to. Oh-oh. 
+
    Let's NOT call the whole thing off

    A database wrapper library such as ADODB comes in handy when you need to ensure portability. It provides 
+  you with a common API to communicate with any supported database so you don't have to call things off. 
    
+
+
    ADODB stands for Active Data Objects DataBase (sorry computer guys are sometimes 
+  not very original). ADODB currently supports MySQL, PostgreSQL, Oracle, Interbase, 
+  Microsoft SQL Server, Access, FoxPro, Sybase, ODBC and ADO. You can download 
+  ADODB from http://php.weblogs.com/adodb.
+
    MySQL Example
    
+
    The most common database used with PHP is MySQL, so I guess you should be familiar 
+  with the following code. It connects to a MySQL server at localhost, 
+  database mydb, and executes an SQL select statement. The results are 
+  printed, one line per row. 
+
    $db = mysql_connect("localhost", "root", "password");
+mysql_select_db("mydb",$db);
+$result = mysql_query("SELECT * FROM profiles",$db);
+if ($result === false) die("failed"); 
+while ($fields = mysql_fetch_row($result)) {
+ for ($i=0, $max=sizeof($fields); $i < $max; $i++) {
+		print $fields[$i].' ';
+ }
+ print "<br>\n";
+} 
+
    
+
    The above code has been color-coded by section. The first section is the connection 
+  phase. The second is the execution of the SQL, and the last section is displaying 
+  the fields. The while loop scans the rows of the result, while the for 
+  loop scans the fields in one row.
    
+
    Here is the equivalent code in ADODB
    
+
     include("adodb.inc.php");
+ $db = NewADOConnection('mysql');
+ $db->Connect("localhost", "root", "password", "mydb");
+ $result = $db->Execute("SELECT * FROM profiles");
+ if ($result === false) die("failed");  
+ while (!$result->EOF) {
+	for ($i=0, $max=$result->FieldCount(); $i < $max; $i++)
+		   print $result->fields[$i].' ';
+	$result->MoveNext();
+	print "<br>\n";
+ } 
    
+
    
+
    Now porting to Oracle is as simple as changing the second line to NewADOConnection('oracle'). 
+  Let's walk through the code...
    
+
    Connecting to the Database
    
+
    
+
    include("adodb.inc.php");
+$db = NewADOConnection('mysql');
+$db->Connect("localhost", "root", "password", "mydb");
    
+
    The connection code is a bit more sophisticated than MySQL's because our needs 
+  are more sophisticated. In ADODB, we use an object-oriented approach to managing 
+  the complexity of handling multiple databases. We have different classes to 
+  handle different databases. If you aren't familiar with object-oriented programing, 
+  don't worry -- the complexity is all hidden away in the NewADOConnection() 
+  function.
    
+
    To conserve memory, we only load the PHP code specific to the database you 
+  are connecting to. We do this by calling NewADOConnection(databasedriver). 
+  Legal database drivers include mysql, mssql, oracle, oci8, postgres, sybase, 
+  vfp, access, ibase and many others.
    
+
    Then we create a new instance of the connection class by calling NewADOConnection(). 
+  Finally we connect to the database using $db->Connect(). 
    
+
    Executing the SQL
    
+
    $result = $db->Execute("SELECT * 
+  FROM profiles");
    
+  if ($result === false) die("failed")    ; 
+  
    
+
    
+
    Sending the SQL statement to the server is straight forward. Execute() will 
+  return a recordset object on successful execution. You should check $result 
+  as we do above.
+
    An issue that confuses beginners is the fact that we have two types of objects 
+  in ADODB, the connection object and the recordset object. When do we use each?
+
    The connection object ($db) is responsible for connecting to the database, 
+  formatting your SQL and querying the database server. The recordset object ($result) 
+  is responsible for retrieving the results and formatting the reply as text or 
+  as an array.
+
    The only thing I need to add is that ADODB provides several helper functions 
+  for making INSERT and UPDATE statements easier, which we will cover in the Advanced 
+  section. 
+
    Retrieving the Data
    
+
    
+
    while (!$result->EOF) {
+   for ($i=0, $max=$result->FieldCount(); $i < $max; $i++)
+	   print $result->fields[$i].' ';
+   $result->MoveNext();
+   print "<br>\n";
+}
    
+
    The paradigm for getting the data is that it's like reading a file. For every 
+  line, we check first whether we have reached the end-of-file (EOF). While not 
+  end-of-file, loop through each field in the row. Then move to the next line 
+  (MoveNext) and repeat. 
+
    The $result->fields[] array is generated by the PHP database 
+  extension. Some database extensions do not index the array by field name. 
+  To force indexing by name - that is associative arrays - 
+  use the $ADODB_FETCH_MODE global variable. 
+
    +	$ADODB_FETCH_MODE = ADODB_FETCH_NUM;
+	$rs1 = $db->Execute('select * from table');
+	$ADODB_FETCH_MODE = ADODB_FETCH_ASSOC;
+	$rs2 = $db->Execute('select * from table');
+	print_r($rs1->fields); // shows array([0]=>'v0',[1] =>'v1')
+	print_r($rs2->fields); // shows array(['col1']=>'v0',['col2'] =>'v1')
+
    
+
    
+As you can see in the above example, both recordsets store and use different fetch modes
+based on the $ADODB_FETCH_MODE setting when the recordset was created by Execute().
    
+
    ADOConnection
    
+
    Object that performs the connection to the database, executes SQL statements 
+  and has a set of utility functions for standardising the format of SQL statements 
+  for issues such as concatenation and date formats.
    
+  
+
    Other Useful Functions
    
+
    $recordset->Move($pos) scrolls to that particular row. ADODB supports forward 
+  scrolling for all databases. Some databases will not support backwards scrolling. 
+  This is normally not a problem as you can always cache records to simulate backwards 
+  scrolling. 
+
    $recordset->RecordCount() returns the number of records accessed by the 
+  SQL statement. Some databases will return -1 because it is not supported. 
+
    $recordset->GetArray() returns the result as an array. 
+
    rs2html($recordset) is a function that is generates a HTML table based on the 
+  $recordset passed to it. An example with the relevant lines in bold:
+
       include('adodb.inc.php'); 
+   include('tohtml.inc.php'); /* includes the rs2html function */
+   $conn = ADONewConnection('mysql'); 
+   $conn->PConnect('localhost','userid','password','database');
+   $rs = $conn->Execute('select * from table');
+   rs2html($rs); /* recordset to html table */ 
    
+
    There are many other helper functions that are listed in the documentation available at http://php.weblogs.com/adodb_manual. 
+
    Advanced Material
    
+
    Inserts and Updates 
    
+
    Let's say you want to insert the following data into a database. 
+
    ID = 3
    
+  TheDate=mktime(0,0,0,8,31,2001) /* 31st August 2001 */
    
+  Note= sugar why don't we call it off 
+
    When you move to another database, your insert might no longer work.
    
+
    The first problem is that each database has a different default date format. 
+  MySQL expects YYYY-MM-DD format, while other databases have different defaults. 
+  ADODB has a function called DBDate() that addresses this issue by converting 
+  converting the date to the correct format.
    
+
    The next problem is that the don't in the Note needs to be quoted. In 
+  MySQL, we use don\'t but in some other databases (Sybase, Access, Microsoft 
+  SQL Server) we use don''t. The qstr() function addresses this issue.
    
+
    So how do we use the functions? Like this:
    
+
    $sql = "INSERT INTO table (id, thedate,note) values (" 
+   . $ID . ','
+   . $db->DBDate($TheDate) .','
+   . $db->qstr($Note).")";
+$db->Execute($sql);
    
+
    ADODB also supports $connection->Affected_Rows() (returns the 
+  number of rows affected by last update or delete) and $recordset->Insert_ID() 
+  (returns last autoincrement number generated by an insert statement). Be forewarned 
+  that not all databases support the two functions.
    
+
    
+
    MetaTypes
    
+
    You can find out more information about each of the fields (I use the words 
+  fields and columns interchangebly) you are selecting by calling the recordset 
+  method FetchField($fieldoffset). This will return an object with 
+  3 properties: name, type and max_length. 
+
    For example:
    
+
    $recordset = $conn->Execute("select adate from table");
    $f0 = $recordset->FetchField(0);
+
    
+
    Then $f0->name will hold 'adata', $f0->type 
+  will be set to 'date'. If the max_length is unknown, it will be set to 
+  -1. 
+
    One problem with handling different databases is that each database often calls 
+  the same type by a different name. For example a timestamp type is called 
+  datetime in one database and time in another. So ADODB has a special 
+  MetaType($type, $max_length) function that standardises the types 
+  to the following: 
+
    C: character and varchar types
    
+  X: text or long character (eg. more than 255 bytes wide).
    
+  B: blob or binary image
    
+  D: date
    
+  T: timestamp
    
+  L: logical (boolean)
    
+  I: integer
    
+  N: numeric (float, double, money) 
+
    In the above date example, 
+
    $recordset = $conn->Execute("select adate from table");
    
+  $f0 = $recordset->FetchField(0);
    
+  $type = $recordset->MetaType($f0->type, $f0->max_length);
    
+  print $type; /* should print 'D'     */
+
     
+
    Select Limit and Top Support 
+
    ADODB has a function called $connection->SelectLimit($sql,$nrows,$offset) that allows
+you to retrieve a subset of the recordset. This will take advantage of native
+SELECT TOP on Microsoft products and SELECT ... LIMIT with PostgreSQL and MySQL, and
+emulated if the database does not support it.
+
    Caching Support 
+
    ADODB allows you to cache recordsets in your file system, and only requery the database
+server after a certain timeout period with $connection->CacheExecute($secs2cache,$sql) and 
+$connection->CacheSelectLimit($secs2cache,$sql,$nrows,$offset).
+
    PHP4 Session Handler Support 
+
    ADODB also supports PHP4 session handlers. You can store your session variables 
+  in a database for true scalability using ADODB. For further information, visit 
+  http://php.weblogs.com/adodb-sessions
+
    Commercial Use Encouraged
    
+
    If you plan to write commercial PHP applications that you want to resell, you should consider ADODB. It has been released using the lesser GPL, which means you can legally include it in commercial applications, while keeping your code proprietary. Commercial use of ADODB is strongly encouraged! We are using it internally for this reason.

+NLS_Date_Format
+Allows you to use a date format other than the Oracle Lite default. When a literal
+character string appears where a date value is expected, the Oracle Lite database
+tests the string to see if it matches the formats of Oracle, SQL-92, or the value
+specified for this parameter in the POLITE.INI file. Setting this parameter also
+defines the default format used in the TO_CHAR or TO_DATE functions when no
+other format string is supplied.
+
+For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is
+yy-mm-dd or yyyy-mm-dd.
+
+Using 'RR' in the format forces two-digit years less than or equal to 49 to be
+interpreted as years in the 21st century (2000–2049), and years over 50 as years in
+the 20th century (1950–1999). Setting the RR format as the default for all two-digit
+year entries allows you to become year-2000 compliant. For example:
+NLS_DATE_FORMAT='RR-MM-DD'
+
+You can also modify the date format using the ALTER SESSION command.

+USING CLI INTERFACE
+===================
+
+I have had reports that the $host and $database params have to be reversed in 
+Connect() when using the CLI interface. From Halmai Csongor csongor.halmai#nexum.hu:
+
+> The symptom is that if I change the database engine from postgres or any other to DB2 then the following
+> connection command becomes wrong despite being described this version to be correct in the docs. 
+>
+> $connection_object->Connect( $DATABASE_HOST, $DATABASE_AUTH_USER_NAME, $DATABASE_AUTH_PASSWORD, $DATABASE_NAME )
+>
+> In case of DB2 I had to swap the first and last arguments in order to connect properly. 
+
+
+System Error 5
+==============
+IF you get a System Error 5 when trying to Connect/Load, it could be a permission problem. Give the user connecting
+to DB2 full rights to the DB2 SQLLIB directory, and place the user in the DBUSERS group.

+GNU LESSER GENERAL PUBLIC LICENSE
+Version 2.1, February 1999 
+ 
+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+ 
+ 
+Preamble
+The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. 
+
+This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. 
+
+When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. 
+
+To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. 
+
+For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. 
+
+We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. 
+
+To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. 
+
+Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. 
+
+Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. 
+
+When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. 
+
+We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. 
+
+For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. 
+
+In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. 
+
+Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. 
+
+The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. 
+
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". 
+
+A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. 
+
+The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) 
+
+"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. 
+
+Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 
+
+1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. 
+
+You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 
+
+2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: 
+
+
+a) The modified work must itself be a software library. 
+b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. 
+c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. 
+d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. 
+(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) 
+
+These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. 
+
+Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. 
+
+In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 
+
+3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. 
+
+Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. 
+
+This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 
+
+4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. 
+
+If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 
+
+5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. 
+
+However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. 
+
+When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. 
+
+If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) 
+
+Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 
+
+6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. 
+
+You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: 
+
+
+a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) 
+b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. 
+c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. 
+d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. 
+e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. 
+For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. 
+
+It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 
+
+7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: 
+
+
+a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. 
+b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 
+8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 
+
+9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 
+
+10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 
+
+11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. 
+
+If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. 
+
+It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. 
+
+This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 
+
+12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 
+
+13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. 
+
+Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 
+
+14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. 
+
+NO WARRANTY 
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

+
+OK, I hacked out an ADOdb container for PEAR-Auth. The error handling's 
+a bit of a mess, but all the methods work.
+
+Copy ADOdb.php to your pear/Auth/Container/ directory.
+
+Use the ADOdb container exactly as you would the DB
+container, but specify 'ADOdb' instead of 'DB':
+
+$dsn = "mysql://myuser:mypass@localhost/authdb";
+$a = new Auth("ADOdb", $dsn, "loginFunction");
+
+

+>> ADODB Library for PHP4
+
+(c) 2000-2004 John Lim (jlim@natsoft.com.my)
+
+Released under both BSD and GNU Lesser GPL library license. 
+This means you can use it in proprietary products.
+ 
+ 
+>> Introduction
+
+PHP's database access functions are not standardised. This creates a 
+need for a database class library to hide the differences between the 
+different databases (encapsulate the differences) so we can easily 
+switch databases.
+
+We currently support MySQL, Interbase, Sybase, PostgreSQL, Oracle, 
+Microsoft SQL server,  Foxpro ODBC, Access ODBC, Informix, DB2,
+Sybase SQL Anywhere, generic ODBC and Microsoft's ADO. 
+
+We hope more people will contribute drivers to support other databases.
+
+
+>> Documentation and Examples
+
+Refer to the adodb/docs directory for full documentation and examples. 
+There is also a  tutorial tute.htm that contrasts ADODB code with 
+mysql code.
+
+
+>>> Files
+Adodb.inc.php is the main file. You need to include only this file.
+
+Adodb-*.inc.php are the database specific driver code.
+
+Test.php contains a list of test commands to exercise the class library.
+
+Adodb-session.php is the PHP4 session handling code.
+
+Testdatabases.inc.php contains the list of databases to apply the tests on.
+
+Benchmark.php is a simple benchmark to test the throughput of a simple SELECT 
+statement for databases described in testdatabases.inc.php. The benchmark
+tables are created in test.php.
+
+readme.htm is the main documentation.
+
+tute.htm is the tutorial.
+
+
+>> More Info

+For more information, including installation see readme.htm

+John,
+
+I have been an extremely satisfied ADODB user for several years now.
+
+To give you something back for all your hard work, I've spent the last 3
+days rewriting the adodb-session.php code.
+
+----------
+What's New
+----------
+
+Here's a list of the new code's benefits:
+
+* Combines the functionality of the three files:
+
+adodb-session.php
+adodb-session-clob.php
+adodb-cryptsession.php
+
+each with very similar functionality, into a single file adodb-session.php.
+This will ease maintenance and support issues.
+
+* Supports multiple encryption and compression schemes.
+  Currently, we support:
+
+  MD5Crypt (crypt.inc.php)
+  MCrypt
+  Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)
+  GZip
+  BZip2
+
+These can be stacked, so if you want to compress and then encrypt your
+session data, it's easy.
+Also, the built-in MCrypt functions will be *much* faster, and more secure,
+than the MD5Crypt code.
+
+* adodb-session.php contains a single class ADODB_Session that encapsulates
+all functionality.
+  This eliminates the use of global vars and defines (though they are
+supported for backwards compatibility).
+
+* All user defined parameters are now static functions in the ADODB_Session
+class.
+
+New parameters include:
+
+* encryptionKey(): Define the encryption key used to encrypt the session.
+Originally, it was a hard coded string.
+
+* persist(): Define if the database will be opened in persistent mode.
+Originally, the user had to call adodb_sess_open().
+
+* dataFieldName(): Define the field name used to store the session data, as
+'DATA' appears to be a reserved word in the following cases:
+	ANSI SQL
+	IBM DB2
+	MS SQL Server
+	Postgres
+	SAP
+
+* filter(): Used to support multiple, simulataneous encryption/compression
+schemes.
+
+* Debug support is improved thru _rsdump() function, which is called after
+every database call.
+
+------------
+What's Fixed
+------------
+
+The new code includes several bug fixes and enhancements:
+
+* sesskey is compared in BINARY mode for MySQL, to avoid problems with
+session keys that differ only by case.
+  Of course, the user should define the sesskey field as BINARY, to
+correctly fix this problem, otherwise performance will suffer.
+
+* In ADODB_Session::gc(), if $expire_notify is true, the multiple DELETES in
+the original code have been optimized to a single DELETE.
+
+* In ADODB_Session::destroy(), since "SELECT expireref, sesskey FROM $table
+WHERE sesskey = $qkey" will only return a single value, we don't loop on the
+result, we simply process the row, if any.
+
+* We close $rs after every use.
+
+---------------
+What's the Same
+---------------
+
+I know backwards compatibility is *very* important to you.  Therefore, the
+new code is 100% backwards compatible.
+
+If you like my code, but don't "trust" it's backwards compatible, maybe we
+offer it as beta code, in a new directory for a release or two?
+
+------------
+What's To Do
+------------
+
+I've vascillated over whether to use a single function to get/set
+parameters:
+
+$user = ADODB_Session::user(); 	// get
+ADODB_Session::user($user);		// set
+
+or to use separate functions (which is the PEAR/Java way):
+
+$user = ADODB_Session::getUser();
+ADODB_Session::setUser($user);
+
+I've chosen the former as it's makes for a simpler API, and reduces the
+amount of code, but I'd be happy to change it to the latter.
+
+Also, do you think the class should be a singleton class, versus a static
+class?
+
+Let me know if you find this code useful, and will be including it in the
+next release of ADODB.
+
+If so, I will modify the current documentation to detail the new
+functionality.  To that end, what file(s) contain the documentation?  Please
+send them to me if they are not publically available.
+
+Also, if there is *anything* in the code that you like to see changed, let
+me know.
+
+Thanks,
+
+Ross

+  Latest version of ADODB is available at http://php.weblogs.com/adodb
+  ======================================================================
+  
+ This file provides PHP4 session management using the ADODB database
+wrapper library.
+ 
+ Example
+ =======
+ 
+	include('adodb.inc.php');
+	#---------------------------------#
+	include('adodb-cryptsession.php'); 
+	#---------------------------------#
+	session_start();
+	session_register('AVAR');
+	$_SESSION['AVAR'] += 1;
+	print "
+-- \$_SESSION['AVAR']={$_SESSION['AVAR']}
    ";
+
+ 
+ Installation
+ ============
+ 1. Create a new database in MySQL or Access "sessions" like
+so:
+ 
+  create table sessions (
+	   SESSKEY char(32) not null,
+	   EXPIRY int(11) unsigned not null,
+	   EXPIREREF varchar(64),
+	   DATA CLOB,
+	  primary key (sesskey)
+  );
+  
+  2. Then define the following parameters. You can either modify

+ Installation
+ ============
+ 1. Create this table in your database (syntax might vary depending on your db):
+ 
+  create table sessions (
+	   SESSKEY char(32) not null,
+	   EXPIRY int(11) unsigned not null,
+	   EXPIREREF varchar(64),
+	   DATA CLOB,
+	  primary key (sesskey)
+  );
+
+
+  2. Then define the following parameters in this file:
+  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
+	$ADODB_SESSION_CONNECT='server to connect to';
+	$ADODB_SESSION_USER ='user';
+	$ADODB_SESSION_PWD ='password';
+	$ADODB_SESSION_DB ='database';
+	$ADODB_SESSION_TBL = 'sessions'
+	$ADODB_SESSION_USE_LOBS = false; (or, if you wanna use CLOBS (= 'CLOB') or ( = 'BLOB')
+	
+  3. Recommended is PHP 4.1.0 or later. There are documented
+	 session bugs in earlier versions of PHP.
+
+  4. If you want to receive notifications when a session expires, then
+  	 you can tag a session with an EXPIREREF, and before the session
+	 record is deleted, we can call a function that will pass the EXPIREREF
+	 as the first parameter, and the session key as the second parameter.
+	 
+	 To do this, define a notification function, say NotifyFn:
+	 
+	 	function NotifyFn($expireref, $sesskey)
+	 	{
+	 	}
+	 
+	 Then you need to define a global variable $ADODB_SESSION_EXPIRE_NOTIFY.
+	 This is an array with 2 elements, the first being the name of the variable
+	 you would like to store in the EXPIREREF field, and the 2nd is the 
+	 notification function's name.
+	 
+	 In this example, we want to be notified when a user's session 
+	 has expired, so we store the user id in the global variable $USERID, 
+	 store this value in the EXPIREREF field:
+	 
+	 	$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
+		
+	Then when the NotifyFn is called, we are passed the $USERID as the first
+	parameter, eg. NotifyFn($userid, $sesskey).

+ Installation
+ ============
+ 1. Create this table in your database (syntax might vary depending on your db):
+ 
+  create table sessions (
+	   SESSKEY char(32) not null,
+	   EXPIRY int(11) unsigned not null,
+	   EXPIREREF varchar(64),
+	   DATA text not null,
+	  primary key (sesskey)
+  );
+  
+  For oracle:
+    create table sessions (
+	   SESSKEY char(32) not null,
+	   EXPIRY DECIMAL(16)  not null,
+	   EXPIREREF varchar(64),
+	   DATA varchar(4000) not null,
+	  primary key (sesskey)
+  );
+
+
+  2. Then define the following parameters. You can either modify
+     this file, or define them before this file is included:
+	 
+  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
+	$ADODB_SESSION_CONNECT='server to connect to';
+	$ADODB_SESSION_USER ='user';
+	$ADODB_SESSION_PWD ='password';
+	$ADODB_SESSION_DB ='database';
+	$ADODB_SESSION_TBL = 'sessions'
+	
+  3. Recommended is PHP 4.1.0 or later. There are documented
+	 session bugs in earlier versions of PHP.
+
+  4. If you want to receive notifications when a session expires, then
+  	 you can tag a session with an EXPIREREF, and before the session
+	 record is deleted, we can call a function that will pass the EXPIREREF
+	 as the first parameter, and the session key as the second parameter.
+	 
+	 To do this, define a notification function, say NotifyFn:
+	 
+	 	function NotifyFn($expireref, $sesskey)
+	 	{
+	 	}
+	 
+	 Then you need to define a global variable $ADODB_SESSION_EXPIRE_NOTIFY.
+	 This is an array with 2 elements, the first being the name of the variable
+	 you would like to store in the EXPIREREF field, and the 2nd is the 
+	 notification function's name.
+	 
+	 In this example, we want to be notified when a user's session 
+	 has expired, so we store the user id in the global variable $USERID, 
+	 store this value in the EXPIREREF field:
+	 
+	 	$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
+		
+	Then when the NotifyFn is called, we are passed the $USERID as the first
+	parameter, eg. NotifyFn($userid, $sesskey).
