I'm not sure what the goal with this book was, but it fails to deliver on anything positive. First, the coverage of the language as a whole is really weak. Whole subjects are completely glossed over. Moreover, if you're an advanced coder, you won't find anything you don't already know in this book. it's really for begginner's only, but as I've said, the beginner type coverage is really lacking. Worse yet, many of the examples are incomplete, tediously long (useless comments abound), and impractical. If you're looking for a good T-SQL book, keep looking.
