howdy, newbie here

I need to select records from one table that have been orphaned so I can delete them.

Is there a way of selecting only the records where the ProductID in one table DOES NOT equal the ProductID in another?

This little problem has been a thorn in my side ... any help would be great

thanks

You can do it all in one operation:

DELETE FROM Table2 WHERE RecordID NOT IN (SELECT RecordID FROM Table1)
