+!!!  PRIOR TO  ANY FURTHER CHANGES  -> MAKE a backup copy of 'quexs' database ! and working QUEXS  folder on server !!!
+ - in case smth will go wrong you may loose your data!!!
+ 
+ next steps should be done manually (used phpMyAdmin for sql management) , sql querries are for original 'quexs' sql DB structure
+
+
+-->> 1st create new table columns:
+
+/* insert var_id  + type  into sample_import_var_restrict table, fill var_id with continuous numbers (unique)*/
+ALTER TABLE  `sample_import_var_restrict` ADD  `var_id` BIGINT( 20 ) UNSIGNED NOT NULL AUTO_INCREMENT AFTER  `sample_import_id`;
+ ALTER TABLE  `sample_import_var_restrict` ADD  `type` SMALLINT( 10 ) UNSIGNED NOT NULL AFTER  `var`;
+ ALTER TABLE `sample_import_var_restrict` DROP PRIMARY KEY, ADD PRIMARY KEY(`var_id`)
+ 
+ 
+/* insert var_id into sample_var table */
+ALTER TABLE  `sample_var` ADD  `var_id` BIGINT( 20 ) UNSIGNED NOT NULL AFTER  `sample_id`
+
+
+-->> 2nd fill created columns with corresponding data
+
+/* update sample_var table */
+
+UPDATE `sample_var` as sv ,`sample`as s, `sample_import_var_restrict` as sivr  SET sv.`var_id`=sivr.`var_id`  WHERE sv.`var` LIKE sivr.`var`  AND sv.`sample_id`=s.`sample_id` AND   s.`import_id`=sivr.`sample_import_id` 
+
+
+/* update type @ sample_import_var_restrict table, insert corresponding values from sample_var */
+UPDATE  `sample_import_var_restrict` ,
+`sample_var` SET  `sample_import_var_restrict`.`type` =  `sample_var`.`type` WHERE  `sample_import_var_restrict`.`var_id` =  `sample_var`.`var_id`
+
+
+--> 3d   some cleanup 
+ 
+/*--> check if there're   unmatched strings for previously "de-identified" samples*/
+SELECT * FROM  `sample`  LEFT JOIN `sample_var` ON (`sample`.sample_id = `sample_var`.sample_id) WHERE `sample_var`.sample_id IS NULL
+ 
+/* --> delete `Time_zone_name` and `phone` data from `sample` table for previously "de-identified" samples from `sample_var` table*/

+
+ 
+/* delete records for deidentified sample strings*/
+DELETE FROM  `sample_import_var_restrict` WHERE  `type` =0
+
+--> !!!  VERY Important !!!  check that collations and  character sets are the same for all tables in DB (f.i.  utf8_unicode_ci )
+
+		probably need some php and sql querry here...
+
+
+--> !!!!QUOTA Row SHOULD BE FINISHED AND CLEARED FOR ALL SAMPLES AND QUESTtionnaires!!!! 
+--> (could influence quota calculation and behaviour because now switched to sample.var_id instead of sample.var )
+
+/* add column for var_id*/
+ALTER TABLE  `questionnaire_sample_quota_row` ADD  `exclude_var_id` BIGINT( 20 ) NOT NULL AFTER  `completions`
+
+/*fill `exclude_var_id` with relevant data for `exclude_var_id` = `var_id`*/
+UPDATE  `questionnaire_sample_quota_row` as qsqr, `sample_import_var_restrict` as sivr SET  qsqr.exclude_var_id =  sivr.var_id WHERE  qsqr.sample_import_id =  sivr.sample_import_id and qsqr.exclude_var = sivr.var
+
+
+--> 4th  update *.php files in 'quexs' folder according to the branch revisions
+
+-->  Finish list
+
+CHECK program is working OK : 
+	ADMIN - > samplesearch, samplelist, dataoutput, superviser, quotas , lime(export data)
+	operator panel -> displaying respondent data as required
+
+
+
+update file admin/functions.import.php - > remove sample_var.`var`, sample_var.`type` from importing data 
+
+delete columns `var` and `type`  from `sample_var` table
+
+
+THE END
