Oracle PL/SQL Programming has been an indispensable reference for both novice and experienced PL/SQL developers since its first edition. Now in its third edition, the book has been thoroughly revised and updated to include the latest Oracle releases--Oracle8i and Oracle9i--the "Internet databases" that communicate with other technologies, such as Java, to run powerful e-commerce applications. Oracle has made substantial changes to the PL/SQL language, and developers who want to take full advantage of its power will find the information they need in this book. Authored by renowned PL/SQL experts Steven Feuerstein and Bill Pribyl, the new edition of the book includes all PL/SQL language features up to and including Oracle 9i Release 2 (9.2). Regardless of the version you are using, from Oracle 7.3.4 to Oracle 9i, this book will answer your questions. In addition, Oracle PL/SQL Programming now contains much-requested new chapters on Oracle triggers, the internal architecture of PL/SQL in the Oracle database, and the use of PL/SQL with Java. The authors have carefully constructed each chapter of this new edition with three objectives: to help you take full advantage of PL/SQL, learn to use PL/SQL to solve your problems, and to write efficient, maintainable code.

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.
