I would agree, sort of, that as the number of rows isn't that great,
throwing away the rest is not too expensive. But surely, at some point,
someone is going to write a similar query against a huge table where it
does become a problem?

Personally, I'm of the opinion of getting the better solution working
for all cases is the best thing to do. 

Just a thought. Your situation might be such that it's never going to be
a problem.


Cheers,
Norman.
