Table of Contents | Index

For the past ten years, O'Reilly's Oracle PL/SQL

Programming has been the bestselling book on

PL/SQL, Oracle's powerful procedural language.

Packed with examples and helpful recommendations, the

book has helped everyone from novices to experienced

developers, and from Oracle Forms developers to

Trang 32

database administrators make the most of PL/SQL.

The fourth edition is a comprehensive update, adding significant new content and extending coverage to include the very latest Oracle version, Oracle Database

10g Release 2 It describes such new features as the

PL/SQL optimizing compiler, conditional compilation, compile-time warnings, regular expressions, set

operators for nested tables, nonsequential collections in FORALL, the programmer-defined quoting mechanism, the ability to backtrace an exception to a line number, a variety of new built-in packages, and support for IEEE

754 compliant floating-point numbers.

The new edition adds brand-new chapters on security (including encryption, row-level security, fine-grained auditing, and application contexts), file, email, and web I/O (including the built-in packages DBMS_OUTPUT, UTL_FILE, UTL_MAIL, UTL_SMTP, and

UTL_HTTP) and globalization and localization.

Trang 33

Co-authored by the world's foremost PL/SQL authority, Steven Feuerstein, this classic reference provides language syntax, best practices, and extensive code, ranging from simple examples to complete applications making it a must-have on your road to PL/SQL mastery.

A companion web site contains many more examples and additional technical content for enhanced learning.
