Db2 13 – Creating and Maintaining Db2 Programs


5 hours


The Create and Maintain Db2 Programs course describes how SQL can be invoked from an application program and the interaction that can occur between the application program and Db2. Measuring the success of the SQL is then discussed, and the use of SQLCA, and SQLSTATE to determine this. You will then see how cursors can be used to reference table data, and finally how Db2 data is saved and recovered using commits and rollbacks.


Programmers and DBAs requiring training in writing application programs to reference and update Db2 data, particularly in the z/OS environment.

After completing this course, the student should be able to:

  • Describe how SQL can be embedded in an application program
  • Determine the success of SQL execution using SQLCODE and SQLSTATE
