This would also be considered a multi-table-delete, which will work only in the upcoming 4.0. In 3.23.x the delete statement may only refer to one table. Best is probably to do this with a programming language: first select the ids of all rows in questions SELECT tu.Id FROM TemporaryUsers_ToMessWith AS tu, Advantage_Backup AS ab WHERE ab.TempAccountNumber = tu.TempAccountNumber AND tu.TempAccountNumber <> 0; then issue one large DELETE FROM TemporaryUsers_ToMessWith WHERE id in (<your id list>) Of course, that presumes that you have an reasonable id in your table, which you have, don't you? ;-) Bye, Benjamin. -- [EMAIL PROTECTED] --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
