iSeries and AS/400 SQL at Work

Arner (a programmer who has published extensively on integration of AS/400 legacy systems) provides detailed coverage of SQL for business environments relying throughout on practical examples to be performed by the reader using the enclosed CD- ROM. Following discussions of SQL relational concepts and terms, the more advanced chapters teach how to become proficient in industry standard SQL to manipulate AS/400 data, use scalar functions to summarize data, and make legacy RPG and COBOL programs AS/400 compatible. This guide will be useful both to beginners or those who are already adept with SQL. Annotation c. Book News, Inc., Portland, OR (booknews.com)
