This book is a complete SQL functions reference for all of the major RDBMS vendors in today’s market. The SQL implementations covered in this book include ANSI SQL, Oracle, Microsoft SQL Server, Sybase, IBM Universal Database (UDB) DB2, MySQL, and PostgreSQL. As a SQL programmer, you will find that there is a growing need to effectively use SQL functions, yet there are few resources to serve as an aid. You will also encounter the need to cross-reference different SQL implementations, at times having to integrate data between, say, Oracle and SQL Server.Migrations of data from one implementation to another is also very common in data warehousing environments, and as organizations make the commitment to go with another vendor’s relational database management system (RDBMS) to better support evolving business needs. This book is the necessary tool to facilitate expedient function referencing, cross-referencing between implementations, creating userdefined functions (UDFs), and providing tips and examples for applying the use of functions to real-world data-retrieval situations.This book is for the SQL programmer, and any software developer who has a need to effectively retrieve data from a relational database, or to integrate applications with RDBMS implementations. Database administrators and other database users will also discover great value. This book is for readers of all levels, and has been organized in an easy-to-understand format that allows quick search and reference. This book is packed with realistic examples, allowing the reader to immediately apply SQL functions concepts to the job at hand.Although the intent of this book is not to teach you SQL, the introductory chapters we have provided serve as an introduction to the world of SQL, explaining basic SQL concepts and describing how to use SQL to query a database, either with or without the use of functions. The trailing chapters of this book show numerous applications of SQL functions in the modern database world.
