Query: Great book for beginner to advanced level SQL

This book is a must for any developer whether you are writing queries, stored procedures as a programmer or tuning as a DBA. The book is filled with code examples and the accompanying disk has a ton of examples that you can use. It's easy to follow and having the real world examples helps to clarify important points. Ken has written a superb technical book that is a must for anyone that is serious about taking their programming to the next level and become a TSQL guru. Thanks Ken!!!!!!!!
