Just picked up a copy of Core MySQL from Prentice Hall and even a cursory look though some of the chapter is enough for me recomend this book. Among the features covered are replication, transactions and a knowledgable discussion of the various MySQL table types. How does InnoDB differ from BDB or Gemini? What are merge tables go for? What are the limitations of Heap tables? All these questions typically go unanswered in most MySQL books, but Leon Atkinson tackles them adoitly. If you’re serious about administrating MySQL or want to take your MySQL applications to the next level, this book is the one to get. Heck, it even talks about how to use MySQL with an object oriented data model. What’s not to like?
