Hi Fabio,

I did not test speed here. I see what you're doing here though, trying to use rushmore to let the db engine to come to to the conclusion earlier that there is no match. It is somewhat a pitty that the DB engine is not able to determine that in the first place by using a constant like .F.

Walter,
