Query: Typos, inconsistent examples, sidetracked, advocate for Micr

It is obvious this book was a rush to press item. There are so many mistakes and inconsistent example formats in this book that it is an embarrassment. The authors also get sidetracked with many of their examples and leave you hanging. The book does contain SQL, but mostly it promotes "Microsoft tools." I would not recommend this book to anyone wanting to learn SQL. It is simply another rush to market book on how to do X. O'Reilly's SQL Essentials is by far many times better!
