Amazon.com Review
If you're doing database application development in the Oracle environment, you're going to have to know PL/SQL, the company's extended query and update language. If you want your programs to exploit the special capabilities of Oracle software, you'll need to know the language well. That's where the third edition of Oracle PL/SQL Programming comes into play. It's an absolutely comprehensive reference (as well as a rather extensive tutorial) on PL/SQL, ideally suited to answering your questions about how to perform some programming tasks and reminding you of the characteristics of functions, triggers, and other elements of the database programmer's toolkit. The new edition covers calls to Java methods from within PL/SQL programs, autonomous transactions, object type inheritance, and the new Timestamp and XMLType data types. There's also more information about server internals--the way PL/SQL programs are run--than before, better enabling readers to optimize their code for fast and safe execution.

Steven Feuerstein takes care to explain, with prose and example code, the characteristics of PL/SQL elements. In explaining number conversions, for example, he explores Oracle's different ways of formatting numbers, then details the behavior of the to_number function under different conditions (with and without a specified format model, and with National Language Support information attached). It's a helpful approach that will have readers using the index to locate places in which Feuerstein mentions language elements of interest. --David Wall

Topics covered: How to use Oracle PL/SQL in all its manifestations through Oracle9i. Fundamentals of program structure (loops, cases, exceptions, etc.) and execution get attention, as do data types, transaction management, triggers, and the object-oriented aspects of the language. There's also coverage of calls to external Java and C programs.

From the Publisher
Oracle is the most popular database management system in use today, and PL/SQL plays a pivotal role in current and projected Oracle products and applications. PL/SQL is a relatively new programming language providing procedural extensions to the SQL relational database language and to an ever-growing number of Oracle development tools, including SQL*Plus, Oracle Forms, Oracle Graphics, Oracle Reports, and Oracle Developer 2000 (formerly the Cooperative Development Environment (CDE)). It offers a myriad of data types, and such features as cursors, loops, conditional and sequential control statements, exception handlers, records, tables, and constructs for developing modular code (functions, procedures, and packages). Originally a rather limited tool, PL/SQL is now a mature and effective language for developers. As more and more Oracle customers move from the mainframe to client- server configurations, PL/SQL is becoming ever more crucial. It provides the foundation for the code used to distribute processing and transactions across the network. PL/SQL allows the developer to: Design powerful and easy-to-use GUI interfaces in products like Oracle Forms and Oracle Graphics Build complex reports and long-running batch processes Implement critical business rules in database triggers and stored procedures Link a World Wide Web page to an Oracle database Although PL/SQL is very important to Oracle customers, it has not received the attention -- by Oracle Corporation and outside vendors and authors -- that it deserves. The only book previously available on PL/SQL is the overly concise Oracle reference manual. Training courses tend to focus on the flashy side of the new GUI tools and ignore the more complicated PL/SQL programming that is so vital to production applications. Oracle PL/SQL Programming fills a huge gap in the Oracle market. The book provides developers with a single, comprehensive guide to building applications with PL/SQL -- and building them the right way. It's packed with strategies, code architectures, tips, techniques, and fully realized code. The book comes with a disk containing many examples of PL/SQL programs that readers can use immediately or as starting points for further development. Oracle PL/SQL Programming is divided into six parts: Part I introduces PL/SQL, its many versions, the environments in which it operates, PL/SQL language fundamentals, and effective coding style. Part II describes basic PL/SQL statements for variables, cursors, conditional and sequential control, loops, exception handling, records, and tables. Part III describes all of the built-in (predefined) PL/SQL functions and procedures -- string, date, number, and miscellaneous as well as the built-in packages that come with PL/SQL. Part IV describes how to modularize your PL/SQL programs using blocks, procedures, functions, and packages. Part V describes how to debug PL/SQL programs and manage code in the database. It also contains a summary of tips for using PL/SQL most effectively. Part VI contains appendices summarizing the contents of the disk and the calling of stored procedures from Version 1.1.

Surprisingly easy to read
This is one of the best written and easiest to read of any technical book I've ever read. We've often provided this book to students in the Oracle classes that we teach. Furthermore, when I was on an Oracle consulting project a couple of years ago, working alongside consultants from Oracle Corporation, I noticed that the Oracle Corp consultants weren't using the Oracle Corp documentation on PL/SQL for reference - they all had this book.

Steve Feuerstein presents a tremendous overview and in-depth analysis of the PL/SQL language with practical examples. He includes several design recommendations and practical real world examples and recommendations that make this a solid book for PL/SQL professionals who are serious about writing production code.

The TRUE bible for PL/SQL programming (not the one by Urman)
I recommend this book wholeheartedly for beginners as well as veterans of PL/SQL. Especially against the Oracle Press book by author Scott Urman. That book (though it covers the basics), it does not give you the tips and tricks or insight as does Steve's book.

The O'Reilly series book is well crafted, with excellent examples. The style of writing is humorous as well as straight forward. And it is a companion amongst other Oracle books by O'Reilly. O'Reilly Publishing seems to know Oracle better than Oracle Press knows itself.

ODTUG Review
Most of us have had to learn PL/SQL at some point in our Oracle careers, and I am sure many of you have become quite expert. On the other hand, some of you may be new to this world of PL/SQL and are looking for a basic text that will educate you in the use of this language.

The "Bible" for PL/SQL programming has long been the earlier editions of this book, and Steven Feuerstein has been considered the guru of PL/SQL programming for as many years as I can remember. Steven has completely revised his best-known work into a new, third edition. I thought that it was time to take a look at this new edition and see what it has to offer both groups. Here is what I found.

Steven now provides complete coverage of PL/SQL from Oracle RDBMS version 7.3.4 through Oracle9i Release 2. He has incorporated all the information from his book PL/SQL Guide to Oracle8i New Features into this book. He has added a new chapter on database triggers and included especially useful information on DDL triggers and database event triggers. He has added new content on the PL/SQL runtime architecture, creating and running PL/SQL programs, and calling Java methods from within PL/SQL. He has integrated all the new Oracle9i features throughout the text, instead of placing them in a separate chapter.

In order to make the book fit into 1,000 pages, some of the example code was removed and can be found on O'Reilly's Web site at www.oreilly.com/catalog/oraclep3 as a zipped file. About 300 files are available. Approximately 200 pages that were pruned from the second edition that still have some utility are also available there.

The book is organized much the same way as previous editions, with a few changes. There are 23 chapters divided into six parts:

Part I: Programming in PL/SQL. These three chapters orient you to PL/SQL, its history, utility, and basic programming constructs.
Part II: PL/SQL Program Structure. Conditional, sequential, iterative control structures, and exceptions are covered in these three chapters.
Part III: PL/SQL Program Data. Six chapters cover how to manipulate data within PL/SQL procedures and functions. Strings, numbers, datatypes, including the new Oracle9i datatypes, and records and collections are also discussed.
Part IV: SQL in PL/SQL. There are three chapters that cover transactions, data retrieval, and the use of dynamic SQL.
Part V: PL/SQL Application Construction. The four chapters in this part discuss procedures and functions, packages, triggers, and managing PL/SQL applications.
Part VI: Advanced PL/SQL Topics. There are four final chapters that cover the runtime architecture, object-orientation in PL/SQL, PL/SQL and Java, and external procedure calls.

Steven states in his preface that the three objectives of this book are to
1. take full advantage of the features of PL/SQL,
2. use PL/SQL to solve your problems, and
3. write efficient, maintainable code.

Each chapter has been crafted to address these three objectives. His writing style is clear, succinct, and reads like he is sitting next to you chatting about the new things he's learned. The book is absolutely full of code examples. Most of the examples are posed as practical programming problems. He carefully walks you through the lines of example code, clearly explaining the logic used for each step of the program, and points out version-based differences. Steve is also not afraid to express an opinion and will tell you exactly why he chooses a particular method for solving a problem. Notes explaining tips and traps proliferate the book.

So, what do I think about this new edition? His book has the most comprehensive coverage of PL/SQL that I have ever seen. The code examples achieve a level of sophistication that is truly elegant. For a PL/SQL beginner, this book can be the source of all PL/SQL wisdom. Even if you have been programming with PL/SQL for a time, I think you will find the information on Oracle9i new features useful and will find many nuggets of information that can be used immediately to improve your code.
