內容介紹：
If you're a programmer or database administrator who uses SQL in your day-to-day work, this popular pocket guide is the ideal on-the-job reference. You'll find many examples that address the language's complexity, along with key aspects of SQL used in IBM DB2 Release 9.7, MySQL 5.1, Oracle Database 11g Release 2, PostgreSQL 9.0, and Microsoft SQL Server 2008 Release 2.
All example SQL statements in this book execute against a set of tables, with data that you can quickly download. The third edition covers important database changes, including:
Oracle's support of the recursive WITH syntax, and addition of PIVOT and UNPIVOT operators
Functions new to Oracle, such as LISTAGG, NTH_VALUE, and more
PostgreSQL’s support of recursive WITH and some window functions
DB2 syntax and datatypes, some compatible with Oracle
MySQL features such as the TIMESTAMP type and the TO_SECONDS function
