I am not looking for a db specific book. I currently have a good grasp of normalization and most other basic techniques. What I am looking for is more advanced development with a database. Due to the fact I use mysql I haven't had much of a chance to work with some of the advanced features other db's use.

Now that mysql has advanced features and I have access to pervasive, oracle, mssql and others I would like a more indepth study of sql theory. Any suggestions for books? Reviews possibly.
