Thanks longobardia,

I think he found it 2 posts back. I'm trying to get into the habit of helping people who are new to SQL with finding the problems/solutions themselves with a bit of guidance rather than just blindly giving the answer 🙂

Chris,
I couldn't bare the pain any longer reading your suggestions.
Let me give hime the answer:
SELECT T1.ObjectID FROM....
SELECT T2.ObjectID FROM ....
see below:
IF EXISTS(SELECT T1.ObjectID FROM @tmp_subjects t1
INNER JOIN tkObjects o ON t1.ObjectID=o.ObjectID
IF EXISTS(SELECT T2.ObjectID FROM @tmp_objects t2
INNER JOIN tkObjects o ON t2.ObjectID=o.ObjectID

Heh... and, yet, you're ok with all the RBAR calling a single row proc in the earlier post. 😉

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I have to agree with Jeff. Keep the temporary tables and figure out how to get rid of the RBAR in your code. It's all the looping that is making your procedures slow, not the temporary tables. There may be a set-based solution to your problem, but nobody has tried to find it.

We don't have enough information to work on it either. We would need the DDL for all the user defined tables in the procedure, sample data for the tables, the expected results from executing the procedure.
