DB2 SQL PL: Essential Guide for DB2 UDB on Linux, UNIX, Windows, i5/OS, and z/OS

Book description

Using the IBM DB2 SQL Procedural Language (SQL PL), programmers can drive major improvements in database performance, manageability, and time-to-market. Now, IBM's own experts present the definitive guide to DB2 SQL PL development on any platform: Windows, UNIX, Linux, iSeries, or zSeries.

DB2 SQL PL, Second Edition shows developers how to take advantage of every facet of the SQL PL language and development environment. The authors offer up-to-the-minute coverage, best practices, and tips for building basic SQL procedures, writing flow-of-control statements, creating cursors, handling conditions, and much more. Along the way, they illuminate advanced features ranging from stored procedures and triggers to user-defined functions.

The only book to combine practical SQL PL tutorials and a detailed syntax reference, DB2 SQL PL, Second Edition draws on the authors' unparalleled expertise with SQL PL in real business environments. Coverage includes

Using SQL PL to improve manageability and performance, while clearly separating DBA and development roles
Writing more efficient stored procedures, triggers, user-defined functions (UDFs), and dynamic compound SQL
Identifying SQL PL performance bottlenecks--and resolving them
Leveraging new language enhancements for Windows, UNIX, and Linux: improved table function support, session based locking, nested save points, new prepare options, and more
Using new features for iSeries V5R3: built-in string and date/time manipulation functions, SEQUENCE objects, and more
Utilizing zSeries Version 8's integrated stored procedures debugging and improved SQL Conditions support
Mastering DB2 Development Center, the unified development environment for creating DB2 stored procedures

Whether you're developing new SQL PL applications, migrating or tuning existing applications, or administering DB2, you'll find this book indispensable.
