permission

Specifies a permission that can be revoked on a SQL Server login. For a list of the permissions, see the Remarks section later in this topic.

LOGIN :: SQL_Server_login

Specifies the SQL Server login on which the permission is being revoked. The scope qualifier (::) is required.

SERVER ROLE :: server_role

Specifies the server role on which the permission is being revoked. The scope qualifier (::) is required.

{ FROM | TO } <server_principal>

Specifies the SQL Server login or server role from which the permission is being revoked.

SQL_Server_login

Specifies the name of a SQL Server login.

SQL_Server_login_from_Windows_login

Specifies the name of a SQL Server login created from a Windows login.

SQL_Server_login_from_certificate

Specifies the name of a SQL Server login mapped to a certificate.

SQL_Server_login_from_AsymKey

Specifies the name of a SQL Server login mapped to an asymmetric key.

server_role

Specifies the name of a user-defined server role.

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 note 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 note 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
