I bought this book on sale and thought it would be a good reference - looking at how large it is. However, I have not been able to get a single answer to any of my questions.The text goes into no in-depth explanations and it literally has copied the Books On-Line documentation that comes with SQL Server! I don't know how they got by with this as I compared it almost word-for-word in many, many places.I say it's a waste of time because you might as well use SQL's own doc because there's no extra cost and you can search for your topics. Then spend the money to get another reference that goes into more detail and covers what-if scenarios.
