I believe you want SELECT a.id, a.uid FROM Ads a WHERE NOT EXISTS ( SELECT * FROM Members m WHERE m.uid = a.uid )
That'll do a select of the rows you want to delete. Once you've confirmed it correct, change the first line to "DELETE" and it'll delete the rows. cheers, barneyb On Apr 9, 2005 7:26 AM, Johnny Le <[EMAIL PROTECTED]> wrote: > Hi, > > My database is a mess.
