Course Description

This training course teaches the delegate how to write advanced SQL statements including many new features introduced in recent DB2 releases.

Pre-requisites

A working knowledge of the DB2 host environment is advantageous but not essential.

The delegate should be able to code basic to intermediate SQL statements - these skills can be acquired by attending our SQL Workshop.

Objectives

The aim of this course is to provide the delegate with the necessary skills to write advanced SQL queries using DB2 for z/OS.

On completion of this course the student will be able to:

  • use recent DDL enhancements
  • use new data types
  • use the MERGE statement
  • code UNION, INTERSECT and EXCEPT statements
  • use new SQL Scalar Functions
  • use the various GROUP BY features
  • code Common Table Expressions
  • code recursive SQL statements
  • store, generate and manipulate XML data
  • use Business and System Temporal Tables

Environment

The course applies to DB2 running in a z/OS environment.

Customisation

For on-site courses (i.e. at your premises), we are more than happy to tailor the course agenda to suit your exact requirements. In many cases, we are able to build your in-house standards and naming conventions into the delivered course.
