Book Description

ISBN-10: 0131007726 | ISBN-13: 978-0131007727 | Publication Date: December 24, 2002

SQL Procedure Language (SQL PL) is used in DB2 to write database-stored procedures. Stored procedures are used to encapsulate business logic on the database and yield the following benefits: significantly improved application performance, increased application scalability, simplified application development, and reduced network traffic. This book will teach the reader how to set up the development environment and use all language elements of SQL PL through concrete examples and thorough discussions. Also included are expert tips and best practices for achieving optimal performance and code manageability. This book will be a valuable reference for SQL PL code syntax and troubleshooting. There are currently no books on the market that cover the DB2 SQL Procedure Language, although it is extensively used by IBM business partners and other software vendors.

5.0 out of 5 stars The Fastest Path to Mastering DB2 Stored Procedures, January 8, 2003

By 

James Huddleston - See all my reviews

This review is from: DB2(R) SQL Procedure Language for Linux, UNIX and Windows (IBM DB2 Certification Guide Series) (Paperback)

This comprehensive yet concise introduction to DB2's SQL procedural language is the first and best place to find guidance on this crucial topic. Stored procedures are fast becoming the mainstay of successful client/server and Web-based DB2 applications, and this book WILL teach you how to develop them, even if all you currently know is just a bit of SQL.

Written by DB2 experts from the IBM Toronto Labs, this is one of those rare texts that actually imparts expertise. It is eminently readable and crystal clear in its explanations of concepts and their application.

Any and every developer of DB2 stored procedures should read -- and enjoy -- this book

4.0 out of 5 stars embed yourself in db2, December 26, 2004

By 

W Boudville (Terra, Sol 3) - See all my reviews
(VINE VOICE)    (TOP 1000 REVIEWER)    (HALL OF FAME REVIEWER)    (REAL NAME)   

This review is from: DB2® SQL PL: Essential Guide for DB2® UDB on Linux™, UNIX®, Windows™, i5/OS™, and z/OS® (2nd Edition) (Hardcover)

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.

5.0 out of 5 stars DB2 SQL Procedural Language for Linux, UNIX, and Windows, April 14, 2003

By 

B. Vialpando (Dallas TX United States) - See all my reviews

This review is from: DB2(R) SQL Procedure Language for Linux, UNIX and Windows (IBM DB2 Certification Guide Series) (Paperback)

Conversational in tone, interesting to follow, this book reads more like a novel that keeps you turning pages with avid interest rather than another dry "technical" resource. As someone who deals with SQL PL on an almost daily basis, I was pleasantly surprised to find I learned many things going through this book. The authors don't try to cover every tangent on the subject, and end up with an excellent resource with specific examples that deal with the topic it covers well: DB2 UDB SQL PL.
