Now van der Lans has systematically updated this classic guide to reflect the latest SQL standards and the newest versions of today's leading RDBMSs: Oracle, Microsoft SQL Server, DB2, and MySQL. Using case study examples and hands-on exercises, van der Lans illuminates every key SQL concept, technique, and statement. Drawing on decades of experience as an SQL standards team member and enterprise consultant, he reveals exactly why SQL works as it does-and how to get the most out of it.

Whether you're a programmer or DBA, a student or veteran, this book will take you from "apprentice" to true SQL master. Writing queries and updating data: all you need to know about SELECT Working with joins, functions, and subqueries Creating database objects: tables, indexes, views, and more Specifying keys and other integrity constraints Using indexes to improve efficiency Enforcing security via passwords and privileges Building stored procedures and triggers Developing with embedded SQL and ODBC Working with transactions, including rollbacks, savepoints, isolation levels, and more Optimizing performance by reformulating SQL statements Using object-relational features: subtables, references, sets, and user-defined data types Reference section: SQL statement definitions and SQL function lists

SQL was, is and always will be the database language for relational database systems such as Oracle, DB2, Sybase, Informix and Microsoft SQL Server. Introduction to SQL describes in depth the full capacity of SQL as it is implemented by the commercial databases, without neglecting the most recent changes to the standard, bringing the book up to date and fully compliant with SQL3. Unique in the extent of its coverage, this book takes you from the beginning to the end of SQL, the concepts to the practice, the apprentice to the master. Learn how to:
* Query data
* Update data
* Create tables and views
* Specify primary and foreign keys
* Use indexes
* Secure your data
* Develop stored procedures and triggers
* Develop applications with embedded SQL and ODBC
* Carry out transactions
* Optimize statements
* Deal with object-relational concepts such as subtables, references, sets and user-defined data types. NEW

section devoted to stored procedures and triggers NEW

coverage of object-oriented concepts NEW

information on application development with pre-programmed SQL NEW

chapter on using SQL in combination with ODBC The best way to learn a language is to work with it and the accompanying CD-ROM contains an SQL product called SOLID, chosen because it employs every aspect of SQL covered in the text. Experiment using the exercises in the book.

Fully updated to cover SQL2, this new edition is a complete introduction to SQL and includes a tutorial disk. The disk contains the database example described within the book and a brief version of Quadbase-SQL. Readers will benefit from working with a "real" SQL product and by building their own database with addresses.

This work provides a technical introduction to the features of SQL. Aimed at those new to SQL, but not new to programming, it provides the reader with essential skills required for programming with this language
