You'll also want to use mysql_real_escape_string() by the looks of it to attempt to stop SQL injection. Something like this will do it: $db1 = mysql_connect($host,$user,$pass); $db2 = mysql_connect($host,$user,$pass); mysql_select_db('db1',$db1); mysql_select_db('db2',$db2); // do your queries with $DB1 $result = mysql_query("delete from userprefs where clientr=".mysql_real_escape_string($user,$db1)."", $db1); // do your queries again with $DB1 mysql_close($db1);//close db1 mysql_close($db2);//close db2 Cheers Adam. ============================================================================= This email is intended solely for the recipient and is confidential and not for third party unauthorised distribution.
