About this series

This series of six DB2 SQL Procedure Developer tutorials covers all the basic constructs and methods of the SQL Procedural Language and shows how it can be used in stored procedures, user-defined functions, and triggers, including error handling and deployment. It also covers some DB2 9.5 advanced features like optimistic locking, hierarchical queries, and declared global temporary tables. This series provides specifics on how stored procedures, user-defined functions, and triggers can be invoked, and how you can share data between procedures and functions. It introduces DB2 development tools, including IBM Data Studio. These tutorials provide a solid base for each section of the exam. However, you should not rely on these tutorials as your only preparation for the exam. More exam resources can be found in the Resources section of this tutorial.
