Good Question. Maybe specify database version though as that only became valid in 2012.

Any examples of how these would be used?

Running totals. Traditionally done with slow set-based code, with a (relatively!) fast cursor, or with some dangerous unsupported side effect of a language feature.


Unsupported... Yes. Dangerous? No and I do wish you'd get over that. ;-)

--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

Some say this was an easy one. For me I had to do some research. I hadn't used this with ROWS and RANGE before. I learned something today.
