This unique cookbook contains a wealth of solutions to problems that SQL programmers face all the time. The recipes inside range from how to perform simple tasks, like importing external data, to ways of handling issues that are more complicated, like set algebra. Authors Ales Spetic and Jonathan Gennick, two authorities with extensive database and SQL programming experience, include a discussion with each recipe to explain the logic and concepts underlying the solution.SQL (Structured Query Language) is the closest thing to a standard query language that currently exists, and Transact-SQL -- a full-featured programming language that dramatically extends the power of SQL -- is the procedural language of choice for both Microsoft SQL Server and Sybase SQL Server systems. The Transact-SQL Cookbook is designed so you can use the recipes directly, as a source of ideas, or as a way to learn a little more about SQL and what you can do with it. Topics covered include:

Despite its wide availability and usage, few developers and DBAs have mastered the true power of Oracle SQLPlus. This bestselling book--now updated for Oracle 10g--is the only in-depth guide to this interactive query tool for writing SQL scripts. It''s an essential resource for any Oracle user.The new second edition of Oracle SQLPlus: The Definitive Guide clearly describes how to perform, step-by-step, all of the tasks that Oracle developers and DBAs want to perform with SQLPlus--and maybe some you didn''t realize you could perform.With Oracle SQLPlus: The Definitive Guide, you''ll expertly:

SQLLoader is a ubiquitous tool in the Oracle world. It has been shipped with Oracle since at least Version 6 and continues to be supported and enhanced with each new version of Oracle, including Oracle8 and Oracle8i. The job of SQLLoader is to load data from flat files into an Oracle database. It''s optimized for loading large volumes of data, and is flexible enough to handle virtually any input format.Almost every Oracle user has to use SQLLoader at one time or another, and DBAs are frequently called upon to load data for the users in their organization. Despite SQLLoader''s wide availability and usage, few DBAs and developers know how to get the most out of it. Oracle SQLLoader: The Definitive Guide has everything you need to know to put SQLLoader to its best use: an introduction to SQLLoader, a reference to all of its syntax options, and most importantly, step-by-step instructions for all the SQLLoader tasks you''d want to perform--and maybe some you didn''t realize you COULD perform.You''ll learn how to construct the necessary control files and load from different types of files containing different types of data (e.g., fixed-width data, delimited data, and data of various datatypes). You''ll also learn how to validate data, load it selectively, transform it as it is loaded, and recover after failure. This book explains how to optimize SQLLoader performance by adjusting the transaction size and using the new direct path option. It also covers the newest SQLLoader features--the loading of large object (LOB) columns and the new object types (nested tables, varying arrays, and object tables).Oracle SQLLoader: The Definitive Guide is an indispensable resource for anyone who is new to SQLLoader; a task-oriented learning tool for those who are already using it; and a quick reference for every user. If you want to take best advantage of an essential Oracle tool, you need this book.

Support for regular expressions in SQL and PL/SQL is one of the most exciting features of Oracle Database 10G. Oracle has long supported the ANSI-standard LIKE predicate for rudimentary pattern matching, but regular expressions take pattern matching to a new level. They provide a powerful way to select data that matches a pattern, as well as to manipulate, rearrange, and change that data.This concise pocket guide is part tutorial and part quick-reference. It''s suitable for those who have never used regular expressions before, as well as those who have experience with Perl and other languages supporting regular expressions. The book describes Oracle Database 10G''s support for regular expressions, including globalization support and differences between Perl''s syntax and the POSIX syntax supported by Oracle 10G. It also provides a comprehensive reference, including examples, to all supported regular expression operators, functions, and error messages.O''Reilly''s Pocket References have become a favorite among developers and database administrators everywhere. By providing a wealth of important details in a concise, well-organized format, these handy books deliver just what you need to complete the task at hand. Whether you''re using regular expressions for the first time or applying your skills from other languages to the latest version of Oracle, the Oracle Regular Expressions Pocket Reference is the book to have close by.

The Oracle SQLPlus Pocket Reference is a must-have for anyone working with Oracle databases, especially those looking to maximize the effectiveness of SQLPlus. As Oracle''s long-standing interactive query tool, SQLPlus is available at every Oracle site, from the largest data warehouse to the smallest single-user system. Despite its wide use, however, SQLPlus is still often not completely understood or fully utilized.Database administrators and developers alike will therefore find the Oracle SQLPlus Pocket Reference to be extremely beneficial. In addition to summarizing all of the SQLPlus syntax and format options, including new Oracle Database 10g features, this handy, on-the-job guide specifically shows readers how to:

SQL is the language of databases. It''s used to create and maintain database objects, place data into those objects, query the data, modify the data, and, finally, delete data that is no longer needed. Databases lie at the heart of many, if not most business applications. Chances are very good that if you''re involved with software development, you''re using SQL to some degree. And if you''re using SQL, you should own a good reference or two.

Now available in an updated second edition, our very popular SQL Pocket Guide is a major help to programmers, database administrators, and everyone who uses SQL in their day-to-day work. The SQL Pocket Guide is a concise reference to frequently used SQL statements and commonly used SQL functions. Not just an endless collection of syntax diagrams, this portable guide addresses the language''s complexity head on and leads by example. The information in this edition has been updated to reflect the latest versions of the most commonly used SQL variants including:

Solutions in this book are divided into chapters by problem domain. Each chapter is a collection of solutions around a single facet of the language such as writing queries, developing triggers, and applying aggregate functions. Each solution is presented code-first, giving you a working code example to copy from and implement immediately in your own environment. Following each example is an in-depth description of how and why the given solution works. Tradeoffs and alternative approaches are also discussed.
