This class combines the content from the Accessing Data Using SQL, Database Design Using SQL, and RPG IV Programming with Embedded SQL classes into one comprehensive week of SQL training.
SQL is playing an ever-increasing IBM i role in enterprise database design, supplanting legacy DDS. This class shows you how to use industry-standard SQL Data Definition Language to build an IBM i database. In addition, it covers retrieving, analyzing, manipulating, and modifying your data using SQL Data Manipulation Language. The class will also cover embedding SQL statements into your RPG IV programs to combine the best of SQL and RPG IV.
Recommended schedule: 4 day lab workshop
This class is presented live at your location, anywhere in the world, using your training/conference facilities.
