Re: Temp table in Procedure

If you use at least Oracle 8i, why use a temporary table anyway? Why not make using a more "modern" approach, such as bulk collects in a collection. If coded properly, I promise that it would run at least 5 times faster. Contact me if you don't know how to do that, I could offer some guidance (just remove the JUNK from my username for my email address).
