It's nice to finally see a high-profile book released for MySQL (and in all fairness mSQL, even though it's not nearly as popular)
This should help boost recognition for these two fine, and FREE, database systems, as well as give practical examples for everyone to use to get their systems and applications to work with them.
A few typos and inaccuracies, as others have pointed out, but the value of the book is still worth every penny.
Good job, ORA, I hope you rush to get another edition out for this book.
