This volume will take you from novice to master, covering not only how to use SQL but also the Oracle extensions to SQL. The examples feature the sample schemas available with Oracle Database 10g, and free code will be available for download.
Very comprehensive reading material on SQL it self. Syill miss some point but that no a weakness becaus Oracle Database is too complicated to be covered just in one book. Even the SQL part. I use it as my standard teaching guide for my students
A classical SQL manual. Good reference for SQL constructs, functions, datatypes and so on... I have not bought the 11g version, only because my interests are elsewhere.
