Its purpose is not to teach database theory from first principles or to provide a full database administration manual. Instead, it condenses frequently needed SQL syntax, examples, and implementation notes into an accessible lookup format. The third edition addresses commonly used SQL across IBM DB2 9.7, MySQL 5.1, Oracle Database 11g Release 2, PostgreSQL 9.0, and Microsoft SQL Server 2008 Release 2. Gennick organizes material largely around SQL terms and tasks, making it possible to move quickly from a forgotten command to a usable pattern. Coverage includes data retrieval, joins, aggregation, transactions, data modification, functions, conversion, regular expressions, and window functions. The guide is therefore best understood as a comparative working reference: it helps readers distinguish broadly shared SQL practices from the syntax and feature differences that arise among major database products.
