DB2 Stored Procedures Programming

( Duration: 2 Days )

The DB2 Stored Procedures Programming training course exposes you to the IBM Optim Development Studio GUI tool to rapidly develop and test SQL stored procedures using the SQL Procedural Language. In addition to using the GUI tool to develop and implement stored procedures, you are taught to implement these SQL stored procedures using a text editor with the IBM DB2 Command Window and the Command Editor.

By attending DB2 Stored Procedures Programming workshop, yous will learn to:

  • Describe stored procedures
  • List Intel platform requirements for supporting DB2 stored procedures
  • Discuss and demonstrate capabilities of the IBM Optim Development Studio to implement SQL stored procedures
  • Describe basic SQL procedure structure
  • Demonstrate the use of SQL Procedure Language Elements
  • Use cursor processing to return result sets to the invoker
  • Handle Exceptions
  • Nest Stored Procedures
  • Use IBM Optim Development Studio debugging capability to debug an SQL stored procedure
  • Use sqlpltrc API to trace SQL stored procedures
  • Employ security techniques for SQL procedures
  • Analyze and improve SQL access plans

  • Knowledge of SQL

This DB2 Stored Procedures Programming class is intended for Database Application Designers and Database Application Programmers supporting DB2 stored procedures in a Linux, UNIX, or Windows environment.
