Sams Teach Yourself SQL in 10 Minutes, Second Edition is a tutorial-based book, organized into a series of easy-to-follow, 10-minute lessons. These well-targeted lessons teach you in 10 minutes what some books take several hours or days to teach. Instead of dwelling of database theory and relational design, this book takes a very hands-on approach to solving the needs of the majority of SQL users who simply need to interact with data.
