Gene,
Like Mark said, try it and find out. The side-effect of figuring out how
to test and measure a hypothesis like this is worth FAR more in the long
run than the value of the specific answer that you/they find out.
Why guess? ...when you can KNOW.

Subject: Table Joins
Hi all:
One of my developers insists that joins by numerical fields result in
better preformance than the joins by
character fields. I don't remember reading much on this point. Is there
any
truth in it?
thank you
