Structured Query Language (SQL) is a programming language to manage data in relational database management systems (RDBMS).
While the language is standarized, the different available database management systems (DBMS) provide implementations of their own that extend and slightly change the language syntax. To take advantage of all the features provided by your DBMS, check its documentation: DB2, Firebird, Informix, InterBase, Microsoft SQL Server, MySQL, NexusDB, Oracle, PostgreSQL, SQLite.
