RBAR Bad. Sets good.

I will show some way too common uses of RBAR (Row by Agonizing Row) processing and show different examples of how they can be replaced with a set based approach.
We will look at performance comparisons and talk about code maintainability. Most of the examples are war stories from my 20 years working with databases. I may or may not be responsible for many of the bad examples myself.
