Overview

This course enables you to acquire the skills necessary to produce application programs that manipulate DB2 databases.

Emphasis is on embedding Structured Query Language (SQL) statements and preparing programs for execution.

Audience

This intermediate course is for application programmers who need to write embedded SQL programs in COBOL or PL/I (on z/OS).

Prerequisites
