I was looking to buy one good, comprehensive reference book re: SQL/400. This is not it. Too basic, with limited examples. Most functions are covered with one paragraph descriptions, with the whole book coming in a skinny, soft-covered, and under a half inch thick.
A good reference guide for SQL commands
Rating: 4/5
This is the only book that I have found which provides reasonably comprehensive coverage of the SQL capabilities which have been introduced on the AS/400 since V4. It provides a good reference for the AS/400 syntax of functions such as CASE, CAST, and various date functions that aren't covered will on other books that I have seen. This book is better as a reference tool than as an introductory tutorial.
Too Basic - Doesn't serve the purpose
Rating: 1/5
This book is too basic and does't serve the purpose even for novice programmers.
