>I was afraid that was the answer. Is there anything I need to watch out for using RECCOUNT()? Everything seems to be working fine for now. I'm using this to see if the SQL returns any "child" records before deleting a parent record.

Doug,

What about using a subquery in the WHERE clause of the DELETE to prevent the deletion if any children exists:

DELETE FROM parent
WHERE pk = something AND NOT EXIST
(SELECT * FROM child WHERE fk = parent_pk)
