Gives programmers two-in-one coverage, with both a "e;how-to"e; on SQL functions and a complete SQL functions reference SQL is the standard language for database queries; this book's advanced coverage helps programmers write their own SQL functions Covers both the internationally standardized SQL 99 functions and the hundreds of additional functions introduced by vendors, including the subtle variations required to successfully migrate or interoperate between vendor products Covers the latest versions of the major relational database management system (RDMS) applications: Microsoft SQL Server, Oracle, IBM DB2, and MySQL
