Arguments
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
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.
Remarks
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.
SQL Server login or server role permission | Implied by SQL Server login or server role permission | Implied by server permission |
---|---|---|
CONTROL | CONTROL | CONTROL SERVER |
IMPERSONATE | CONTROL | CONTROL SERVER |
VIEW DEFINITION | CONTROL | VIEW ANY DEFINITION |
ALTER | CONTROL | ALTER ANY LOGIN ALTER ANY SERVER ROLE |
Permissions
For logins, requires CONTROL permission on the login or ALTER ANY LOGIN permission on the server.
For server roles, requires CONTROL permission on the server role or ALTER ANY SERVER ROLE permission on the server.
Examples
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
