Removes a database user from the current database.
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use DROP USER instead.
When the database user is removed, the permissions and aliases that depend on the user are also removed.
sp_revokedbaccess can remove only database users from the current database. Before removing a database user that owns objects in the current database, you must either transfer ownership of the objects or drop them from the database. For more information, see ALTER AUTHORIZATION (Transact-SQL).
sp_revokedbaccess cannot be executed within a user-defined transaction.
The following example removes the database user mapped to Edmonds\LolanSo from the current database.
EXEC sp_revokedbaccess 'Edmonds\LolanSo'; GO
