I have seen Row number used in several occasions and always struggled to understand it. This article is very clear and practical. I expect to start using these functions soon. Thanks.

Good article.

I've become very fond or ROW_NUMBER() lately, it's an efficient way of doing what I need to do for a large report.

Loved it! New features like ranking functions tend to be underutilized, since people prefer to stick with true and tried. Articles like this one, really clarify things and help us start using these features.

I'm a little late on the feedback after the formatting fix and I apologize for that. VERY nicely done, Wayne. This will help a lot of folks just getting into Windowing functions.

--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
