Heh... you're such a "NOTty" boy! 😀 I haven't seen syntax like that in a very long time. Lot's of bloody != but incredibly little !< and !>.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Well, nothing reading the text for both answers. The fact that both answers were used is probably interesting in itself.

Heh... the only difference appears to be the different number of people that thought it was a correct answer. 😀

Interesting.. Didn't even know that this was in T-SQL. I got the answer right because I have programmed in C. Is this just a T-SQL thing or is it standard SQL ( whatever that is ) ?

Thanks for the question, Steve!

The next question would be, what is the best way to write this for readability? Should we be using "NOT" or flip the operator to use ">". Looking through legacy code, I see "!" more often.
