Now available in an updated second edition, our very popular 'SQL Pocket Guide' is a major help to programmers who use SQL in their day-to-day work. Not just an endless collection of syntax diagrams, this small guide addresses the language's complexity head on and leads by example. The information in this edition is updated to reflect the latest versions of Oracle Database 10g, Release 2; the free Oracle Database 10g Express Edition (XE); Microsoft SQL Server 2005; MySQL 5; and IBM DB2 8.2. There is also added coverage of the PostreSQL 8.1 database. The "SQL Pocket Guide" is a concise reference to frequently used SQL statements and commonly used SQL functions.
