The link didn't work even when I copied and pasted it. I did, however, find the questions on your site.

--Jeff Moden
"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."

(play on words) "Just because you CAN do something in T-SQL, doesn't mean you SHOULDN'T." --22 Aug 2013

"Has anyone ever told you that a query you have written runs too fast?" - Dwain Camps - 6 Mar 2014
