SQL is playing an ever-increasing role in the IBM i operating system (aka iSeries, AS/400) in enterprise database design, supplanting legacy DDS. This class shows you how to embed SQL statements into your RPG IV programs to combine the best of SQL and RPG IV. It also introduces the concept of SQL stored procedures.
Recommended schedule: 2 days
This class is presented live at your location, anywhere in the world, using your training/conference facilities.
