Good for reading...better for reference

"Teach Yourself in 21 Days" should imply to most that this isn't the book that is going to go over every topic in fine detail. You aren't going to become a SQL genius in 21 days, anyway. It gives a good broad range of topics. But also, if you don't know what SQL is or haven't seen a little, then you probably won't understand what you are learning. The samples and the code in this book seemed to work for me. I mostly use it as a reference to look up the correct syntax for code I don't use all the time.
