I can still remember one of those Eureka moments. I was reading a post from Wayne Sheffield and he explained that in order to understand set programming in sql you need to "stop thinking about what you want to do to a row and instead think about what you want to do to a column". Not sure I got the quote exactly right but for whatever reason that flipped a switch in my brain and it all became clear.I believe Mr. Sheffield was quoting me in that post. Please see my signature line. 🙂
Or maybe I just gave the credit to the wrong person. It was several years ago so I very well have remembered it wrong. It is certainly possible that it was just from reading your signature. Regardless of where I first I heard it, the concept made a huge impact on me. So a big thanks Jeff!!!
