Oracle SQL: the Essential Reference

SQL (Structured Query Language) is the heart of a relational database management system. It's the language used to query the database, to create new tables in the database, to update and delete database fields, and to set privileges in the database. Oracle SQL: The Essential Reference is for everyone who needs to access an Oracle database using SQL--developers, DBAs, designers, and managers.SQL is based on research dating back to the late 1960s, but its first commercial release was in the RDBMS announced by the fledgling Oracle Corporation in 1979. Since that time, every other database vendor has adopted SQL, and ANSI and the ISO have made it a standard. Although vendors diverge in their extensions to SQL, the core language is standard across vendor boundaries.Despite SQL's long history and relative simplicity, few developers and database administrators are truly masters of SQL. The constant stream of vendor enhancements, the hard-won experience in tuning SQL for best performance, and the requirements of particular operational environments mean that there is always more to learn about SQL.Oracle SQL: The Essential Reference delivers all the information needed to keep ahead of the learning curve on standard SQL and Oracle's extensions to it. This single, concise reference volume will hold its own against a stack of Oracle manuals and even yield insights and examples not available in those manuals.There are chapters on basic SQL elements (nami.
