Comment: SQL for Smarties by Joe Celko (Score 1) 517
This was a pretty awesome book showing some of the cool things that you can do with set-based programming and SQL databases: medians, efficient tree-storage, and even string parsing!
The edition I read had a lot of typos, but they are generally pretty obvious. The author is also rather active in newsgroups, so there is a lot of supplemental information and the ability to ask questions.
