Data control language : ウィキペディア英語版 | Data control language
A data control language (DCL) is a syntax similar to a computer programming language used to control access to data stored in a database (Authorization). In particular, it is a component of Structured Query Language (SQL). Examples of DCL commands include: * GRANT to allow specified users to perform specified tasks. * REVOKE to cancel previously granted or denied permissions. The operations for which privileges may be granted to or revoked from a user or role may include CONNECT, SELECT, INSERT, UPDATE, DELETE, EXECUTE, and USAGE. In the Oracle database, executing a DCL command issues an implicit commit. Hence you cannot roll back the command. In PostgreSQL, executing DCL is transactional, and can be rolled back. ==See also==
* Data definition language * Data manipulation language
