Cary,
From the league of learners and eager apprentices. We eagerly devour any repetition on your part or that matter any other of the guru's. :)
But seriously I for one don't have an in house guru to whom I can lookup to for gems of wisdom and guidance. I am sure I am not alone in this predicament. So anything is far better than nothing!
Thanks for your contributions - all of you!
Denham

SQL that does excessively many reads from memory. Trace it. Read "Why
you should focus on LIOs instead of PIOs" at www.hotsos.com/catalog.
My apologies to the list for repeating myself like a broken record. :)
