Advanced SQL functions in Oracle 10g

Oracle 10g has introduced new features into it srepertoire of SQL instructions that make database queries more versatile. When programmers use SQL in Oracle, they inevitably look for easier and new ways to handle queries. What is needed is a way to introduce SQL users to the new features of Oracle 10g concisely and systematically so that database programmers can take full advantag eof the newer capabilities. This book hopes to meet this need by exploring some common new SQL features.

Each chapter includes numerous working examples, and Oracle users can run these examples as they read and workt hrough the book. Also, many books on Oracle 10g present the language syntax alone with no in-depth explanation, analysis, or examples. In this book, we present not only the syntax for new features and functions, but also a thorough clarification and breakdown of the different functions, along with examples of ways they can and should be used.

Designed to exploit Oracle 10g’s SQL, this book takes a comprehensive look at Oracle 10g’s analytical functions, MODEL statements, and regular expressions. In addition, the book covers collection objects and object-oriented structures and introduces new Oracle 10g topics such as XML and statistical functions. The authors’ logical and developmental approach to query building includes a review of older Oracle tools to help in the transition to newer material.

You will learn how to:
- Format result sets with SQL*Plus reporting tools.
- Use aggregate functions for partitioning, ordering, and reporting.
- Perform calculations with the MODEL statement.
- Search within strings using regular expressions.
- Work with collection objects.
- Handle XML within SQL.

This book is meant to be used by Oracle professionals as well as students, but it is not a SQL primer. Readers of this book are expected to have previously used Oracle , SQL*Plus, and, to some extent, PL/SQL. This book can be used for individual study or reference, in advanced Oracle training settings, and in advanced database classes in schools. It is meant for those familiar with SQL programming since most of the topics present not only the syntax, queries, and answers, but also have ananalytical programming perspective to them. This book will allow the Oracle user to use SQL in new and exciting ways.
