The docs say that it sets FOUND to true if it found rows and
discarded them and sets FOUND to false if it did NOT find
rows (and thus did not discard any, either).
This would indeed make sense.
However, reality seems to look different. In the example I
posted it *sets* FOUND to true even though it couldn't find
any rows. This is counter-intuitive.
I just want to make sure this is the intended behaviour (in
which case I will have to work around it) or whether it's me
misunderstanding something - because it seems
counter-intuitive.

That would be good but doesn't influence the PERFORM issue.
Thanks anyways,
