- GRANT OPTION
-
Indicates that the right to grant the specified permission to other principals will be revoked. The permission itself will not be revoked.
Important
If the principal has the specified permission without the GRANT option, the permission itself will be revoked.
- CASCADE
-
Indicates that the permission being revoked is also revoked from other principals to which it has been granted or denied by this principal.
Caution
A cascaded revocation of a permission granted WITH GRANT OPTION will revoke both GRANT and DENY of that permission.
- AS SQL_Server_login
-
Specifies the SQL Server login from which the principal executing this query derives its right to revoke the permission.
SQL Server logins and server roles are server-level securables. The most specific and limited permissions that can be revoked on a SQL Server login or server role are listed in the following table, together with the more general permissions that include them by implication.

A. Revoking IMPERSONATE permission on a login
The following example revokes IMPERSONATE permission on the SQL Server login WanidaBenshoof from a SQL Server login created from the Windows user AdvWorks\YoonM.
USE master; REVOKE IMPERSONATE ON LOGIN::WanidaBenshoof FROM [AdvWorks\YoonM]; GO
B. Revoking VIEW DEFINITION permission with CASCADE
The following example revokes VIEW DEFINITION permission on the SQL Server login EricKurjan from the SQL Server login RMeyyappan. The CASCADE option indicates that VIEW DEFINITION permission on EricKurjan will also be revoked from the principals to which RMeyyappan granted this permission.
USE master;
REVOKE VIEW DEFINITION ON LOGIN::EricKurjan FROM RMeyyappan
CASCADE;
GO
C. Revoking VIEW DEFINITION permission on a server role
The following example revokes VIEW DEFINITION on the Sales server role to the Auditors server role.
USE master; REVOKE VIEW DEFINITION ON SERVER ROLE::Sales TO Auditors ; GO
