Today I'm releasing my free ebook - A Primer on SQL here at Dreamincode. It is a short ebook teaching the basics of SQL assuming no prior knowledge of it. While the examples and text use Ingres as the database management system, the code should work correctly on any SQL compliant database.

2) Getting your Database ready
3) Constraints
4) Operations on Tables
5) Writing Basic Queries
6) Manipulating Data
7) Organizing your Data
8) Doing more with Queries
9) Aggregation and Grouping

I do hope you enjoy the book. Please feel free to share your comments on it.
