This practical guide to SQL focuses on data retrieval and manipulation using the powerful AS/400 dialect. In a proven tutorial format, the authors cover a wide range of SQL material, including selecting data from a single table, using built-in functions, defining and manipulating data, and accessing multiple tables.
Customer Reviews & Comments
The authors do a good job of teaching beginners how to execute SQL on the AS/400. Unfortunately, there have been many enhancements in SQL on this platform since this book was written, and it is sorely out of date. The book can still be considered a good introduction, but it is insufficient for a reader who wants to be able to take full advantage of the SQL capabilities which have been introduced in OS/400 over the past three years.
