Did I mention that I love Red Gate’s Data Generator?

T-SQL, Tools
Because I do. I'm working on a set of tests for an article comparing TOP, MAX & ROW_NUMBER. I have a simple data structure and I need a bunch of data in order to create my tests. I wanted that data to be distributed a certain way, to mimic some production system behavior I've seen in the past.

Great tool!
