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 Power Systems with 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 on how to access the database using SQL. You will learn how to create, maintain, and query the database using the interactive SQL interface and System i Navigator.

• Use data definition language (DDL) to describe tables and views
• Use UPDATE, INSERT, ALTER, and DELETE to modify SQL tables and maintain a database
• Use 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
• Use SQL Query Manager

This intermediate course is designed primarily for experienced IBM i programmers. However, very skilled Power Systems with IBM i users, who want to learn how to use the SQL programming language as a means to access the DB2 for i database, may also consider attending this class. You will learn how to create, maintain, and query the database using the interactive SQL interface and System i Navigator.
