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.

  Warning

  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
