Very good question - got caught out with as well. Should have realized that with out the where clause that each max() is evaluated individually... nice to learn...

However, to do some nitpicking:

1. If I were to try this code on my system, I would get five errors. All system table (*) names are completely lowercase,...

Well, the question is a good one, and I got it right, but if I see code like that I reach for the shot gun.
