Heh... yeah, but it's still fun. :-D

--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.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

when talking with rookies:
- teach them proper t-sql (not addon products!)
- show them ref online (msdn, http, books online, etc)
- do not confuse them with "products", show them code!!!
you are right displaying products there is a form of SPAM
please teach the rookies correctly, good habits from the start

Please note: 3 year old thread (and what I was in this thread was incorrectly accused of being wrong. I've been wrong elsewhere, but not here)
