SQL is a very powerful programming and database language that is widely used in business today. For example, SQL can be used to perform interactive database queries as well as to extract data from a server and pass that data to a Java applet running on a client PC. SQL is frequently used in IBM i high-level languages as an alternate means to access the database.

This course is designed to teach IBM i programmers and highly skilled IBM i users how to access the DB2 database using SQL. You will learn how to create, maintain, and query the database using the interactive SQL interface and System i Navigator.

  • Apply data definition language (DDL) to describe tables and views
  • Use UPDATE, INSERT, ALTER, and DELETE to modify SQL tables and maintain a database
  • Make use of the SELECT statement to extract data from tables and views
  • Code SQL queries that include column and scalar functions
  • Code SQL queries that include inner and outer joins
  • Utilize SQL Query Manager

This is an intermediate course for experienced IBM i (including i5/OS and OS/400) programmers.

You should be able to:

  • Use a Windows-based PC
  • Navigate and use a Windows-based desktop
  • Navigate IBM i menus
  • Use IBM i commands
  • List the data types that are supported by the IBM i DB2 database
  • Explain the use of the data types supported by the IBM i DB2 database

Other courses that may enhance your knowledge are:

  • IBM i Technical Introduction (OL4AG)

Assuming an IBM i programming background, a programmer would attend the database classes in this order:

  • Accessing the IBM i Database Using SQL (OL37G)
  • Developing IBM i Applications Using SQL (OL38G)
