glad you mentioned Relational, Inc. Otherwise one would get the impression that M$ invented everything that is in the current Sql standard. Especially now that Sql Server 2008 is more like Oracle 10/11 than ever, which is actually a good thing.

Since I have a primordial hatred for Oracle, I'll have to strongly disagree with that notion. ;-)

--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.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

Thanks for this Stairway!

I would add only a couple of references - background for the Relational Model:
