[snip] $sql = "SELECT * FROM `table1` LEFT JOIN `table2` USING `id` WHERE ... GROUP BY `table1`.`id`"; mysql_query($sql); the problem is, that, when in table2 is not matching data using that id, i lose that id from output array. but i don`t want to.. is there any posibility to keep that id? [/snip] More of a mysql question but do a left outer join with no group by statement. SELECT table2.* FROM table1 LEFT OUTER JOIN table2 ON(table1.id = table2.id) WHERE table1.id IS NULL Returns all of table2 id's where there is no id in table1 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
