Ryan Stephens, "Sams Teach Yourself SQL in 24 Hours"(Repost)

Welcome to the world of relational databases and SQL! This book is written for those selfmotivated individuals out there who would like to get an edge on relational database technology by learning the Structured Query Language—SQL. This book was written primarily for those with very little or no experience with relational database management systems using SQL. This book also applies to those who have some experience with relational databases but need to learn how to navigate within the database, issue queries against the database, build database structures, manipulate data in the database, and more. This book is not geared toward individuals with significant relational database experience who have been using SQL on a regular basis.
