    Makes it even more interesting if you add following:

    insert into @test-2 values ( NULL )

    Answer is still 6.

    Because aggregate functions ignore NULLs, right?

    Good question today, thanks. I had it nailed on theory and then almost got it wrong by screwing up the math. 24 divided by 4 is NOT 8, duh. Tuesday morning brain, I guess.
