Topic link icon Transact-SQL Syntax Conventions


REVOKE [ GRANT OPTION FOR ] permission [ ,...n ] } 
    ON LOGIN :: SQL_Server_login
    { FROM | TO } <server_principal> [ ,...n ]
    [ CASCADE ]
    [ AS SQL_Server_login ] 

<server_principal> ::= 
        SQL_Server_login
    | SQL_Server_login_from_Windows_login 
    | SQL_Server_login_from_certificate 
    | SQL_Server_login_from_AsymKey

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.

{ FROM | TO } SQL_Server_login: Specifies the SQL Server login 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.

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

A SQL Server login is a server-level securable. The most specific and limited permissions that can be revoked on a SQL Server login are listed in the following table, together with the more general permissions that include them by implication.

SQL Server login permission	Implied by SQL Server login permission	Implied by server permission
CONTROL	CONTROL	CONTROL SERVER
IMPERSONATE	CONTROL	CONTROL SERVER
VIEW DEFINITION	CONTROL	VIEW ANY DEFINITION
ALTER	CONTROL	ALTER ANY LOGIN

Permissions

Requires CONTROL permission on the login or ALTER ANY LOGIN 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
