Thanks Elliott, Jack and Krishna.
Well I don't know... after I received your responses I tried in again and it
worked!!! Some missing comma or something.
Elliot, this was only an example query, the really query is a little
trickier. I am using the minus because using the "not in" (my first choice
by the way), is about 100 times slower than using the minus. I'm sure if I
played with the indexes a little, that could improve on that, however minus
is VERY fast.
Thanks again
Mike
