DB2 SQL PL: Essential Guide For DB2 UBD On Linux, UNIX, Windows, i5/OS, And Z/OS

This is a FANTASTIC PL/SQL reference text for coding needs in the z/OS schema. LUW and iSeries are also documented. Examples are provided for every topic presented. The hardback cover was ordered and the paperback cover returned to ensure the broad utilization of the book would allow for a longer time frame. Multiple team members on the project team utilize this book for reference needs.I would give it a 10 star rating is it were available!!

DB2 SQL PL: The Essential Guide for DB2 is a an excellent tutorial on the topic. This is a must for anyone learning this very important aspect of the DB2 software. The book takes you through a very detailed step by step approach of writing stored procedures with very good examples and very clear explanations. This book will also serve as a good reference.

This is so typically IBM - a total lack of appreciation of the needs of the reader leading to a book that may well contain the information, but makes it near-impossible to find or use. This was a bad book before they updated it and merged in all three major platforms, but now it's just vile - big blocks of platform-specific material that you have to skip past make it a real chore to read.The grammar is poor - if this book had a professional editor, they should be deeply ashamed. Much of the content is warmed-over material from the (also poor) official reference materials, and there is no real narrative structure. Finally, even the indexing is weak.Don't waste your money - the online reference books have all the material, and Google will find you more helpful explanatory material.

This book took my skills to the next level and made me more desirable to my clients. This is the direction to move in for platform portability.

This is a very useful book for people who is going to develop PL SQL procedures. It covers many detail of the DB2 features with many useful samples. I highly recommend it.

It is really a very good book from IBM about DB2-SPL. In our company we bougth a lot of DB2 book, but this is the very best.from basics to tricks

As another reviewer wrote, the text is not very well written but I was prepared to accept that because it provides a disc with examples etc and a colleague was using it. As I loaded the disc, I got Internal Error 2349. What does this mean? Why doesn't it say what it means? Only possible response was OK or to X-close the window. Each resulted in a rollback of the material loaded from the disc. This mystery renders the book near useless. Don't waste your $ on this.(What happened to IBM? It used to be so good...)

The book describes IBM's Procedural Language, which runs on their db2 servers. It is not a general purpose language, like C or Java. Rather, it is tied directly to db2 and IBM's implementation of SQL. But within this context, the book explains the expressive power of PL. It shows at length how you can write stored procedures, triggers and functions in PL. The level of detail and the cited examples should reassure you of PL's capability.But why even write business logic code at the database layer? There have been other books on n-tier application design, which call for the locating of business logic in a middle tier and not at the database. The authors' rejoinder is that while that makes for an elegant design, practical experience shows that often, crucial logic needs to be at the database. This reduces networks traffic and can heavily improve perforance. Hence the need for PL, or something like it.Be wary of the book's claim that PL lets you write "portable application logic". It is portable only between instances of db2 running under linux, unix, Microsoft Windows or IBM's operating systems. When you write embedded logic in PL, you are also embedding yourself or your company into db2. Which may indeed be fine by you. But just so you know.

Das bestellte Buch war schmutzig. Der Bucheinband war mit Kaffeeresten beschmutzt. Innen ok, die Seiten sind i.O., nicht beschädigt.

Super service from sellerBook perfect for my needs as a nascent Data Scientist working with DB2
