If you are looking for advanced SQL-Server techniques, this book is not TOO bad. It is a good starting point for those who have not had the opportunity to learn from experts or experience already. But, there is nothing very earth-shattering in here, as I publish a free book about advanced T-SQL set-based operations, large-database tuning, and more that goes well beyond what is in this book. But, it is better than most SQL-Server books on the market, since many others seem like just barely more than a help-file reprint.
