| WA1337 DB2 for OS390 Application Programming |
|
This workshop is designed to provide instruction on COBOL programming using DB2 for OS/390. Hands-on practice with DB2 will be included, in order to reinforce the concepts and techniques studied in the course. Performance improving techniques will be discussed and the output from the DB2 optimizer will be analysed, using the EXPLAIN facility. |

| Objectives: |
|
After completing this course the student should be able to:
- embed SQL commands into a batch COBOL program to read data from tables and also update DB2 tables.
- code a program to use an SQL "cursor processing" technique.
- Prepare a program for execution.
- execute and test a batch program
- use EXPLAIN to analyse SQL commands.
- know the locking strategies available with DB2.
