The SQL Data Control Language (DCL) is a subset of the SQL language and consists of all SQL statements that support the definition of security authorization for accessing database objects.
- Grant and revoke privileges
- Give ownership of a database to another user
Rules on Entering DCL Statements
- A single-statement request
- The solitary statement, or as the last statement, in an “explicit transaction” (one or more requests enclosed by user-supplied BEGIN TRANSACTION and END TRANSACTION statement in Teradata mode, or in ANSI mode, one or more requests ending with the COMMIT keyword).
- The solitary statement in a macro
A data control statement cannot be entered as part of a multistatement request.
Successful execution of a data control statement automatically creates and updates entries in the Data Dictionary.
