Arguments

• permission
  Specifies a permission that can be revoked on a schema-contained object. For a list of the permissions, see the Remarks section later in this topic.

• ALL
  Revoking ALL does not revoke all possible permissions. Revoking ALL is equivalent to revoking all ANSI-92 permissions applicable to the specified object. The meaning of ALL varies as follows:

  Scalar function permissions: EXECUTE, REFERENCES.

  Table-valued function permissions: DELETE, INSERT, REFERENCES, SELECT, UPDATE.

  Stored Procedure permissions: EXECUTE.

  Table permissions: DELETE, INSERT, REFERENCES, SELECT, UPDATE.

  View permissions: DELETE, INSERT, REFERENCES, SELECT, UPDATE.

• PRIVILEGES
  Included for ANSI-92 compliance. Does not change the behavior of ALL.

• column
  Specifies the name of a column in a table, view, or table-valued function on which the permission is being revoked. The parentheses ( ) are required. Only SELECT, REFERENCES, and UPDATE permissions can be denied on a column. column can be specified in the permissions clause or after the securable name.

• ON [ OBJECT :: ] [ schema_name ] . object_name
  Specifies the object on which the permission is being revoked. The OBJECT phrase is optional if schema_name is specified. If the OBJECT phrase is used, the scope qualifier (::) is required. If schema_name is not specified, the default schema is used. If schema_name is specified, the schema scope qualifier (.) is required.

• { FROM | TO } <database_principal>
  Specifies the principal from which the permission is being revoked.

• GRANT OPTION
  Indicates that the right to grant the specified permission to other principals will be revoked. The permission itself will not be revoked.

  Ważne:
  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.

  Przestroga
  A cascaded revocation of a permission granted WITH GRANT OPTION will revoke both GRANT and DENY of that permission.

• AS <database_principal>
  Specifies a principal from which the principal executing this query derives its right to revoke the permission.

• Database_user
  Specifies a database user.

• Database_role
  Specifies a database role.

• Application_role
  Specifies an application role.

• Database_user_mapped_to_Windows_User
  Specifies a database user mapped to a Windows user.

• Database_user_mapped_to_Windows_Group
  Specifies a database user mapped to a Windows group.

• Database_user_mapped_to_certificate
  Specifies a database user mapped to a certificate.

• Database_user_mapped_to_asymmetric_key
  Specifies a database user mapped to an asymmetric key.

• Database_user_with_no_login
  Specifies a database user with no corresponding server-level principal.

Information about objects is visible in various catalog views. For more information, see Object Catalog Views (Transact-SQL).

An object is a schema-level securable contained by the schema that is its parent in the permissions hierarchy. The most specific and limited permissions that can be revoked on an object are listed in the following table, together with the more general permissions that include them by implication.

Object permission	Implied by object permission	Implied by schema permission
ALTER	CONTROL	ALTER
CONTROL	CONTROL	CONTROL
DELETE	CONTROL	DELETE
EXECUTE	CONTROL	EXECUTE
INSERT	CONTROL	INSERT
RECEIVE	CONTROL	CONTROL
REFERENCES	CONTROL	REFERENCES
SELECT	RECEIVE	SELECT
TAKE OWNERSHIP	CONTROL	CONTROL
UPDATE	CONTROL	UPDATE
VIEW CHANGE TRACKING	CONTROL	VIEW CHANGE TRACKING
VIEW DEFINITION	CONTROL	VIEW DEFINITION

Permissions

Requires CONTROL permission on the object.

If you use the AS clause, the specified principal must own the object on which permissions are being revoked.

Examples

A. Revoking SELECT permission on a table

The following example revokes SELECT permission from the user RosaQdM on the table Person.Address in the AdventureWorks2012 database.

USE AdventureWorks2012;
REVOKE SELECT ON OBJECT::Person.Address FROM RosaQdM;
GO

B. Revoking EXECUTE permission on a stored procedure

The following example revokes EXECUTE permission on the stored procedure HumanResources.uspUpdateEmployeeHireInfo from an application role called Recruiting11.

USE AdventureWorks2012;
REVOKE EXECUTE ON OBJECT::HumanResources.uspUpdateEmployeeHireInfo
    FROM Recruiting11;
GO 

C. Revoking REFERENCES permission on a view with CASCADE

The following example revokes REFERENCES permission on the column BusinessEntityID in the view HumanResources.vEmployee from the user Wanida with CASCADE.

USE AdventureWorks2012;
REVOKE REFERENCES (BusinessEntityID) ON OBJECT::HumanResources.vEmployee 
    FROM Wanida CASCADE;
GO
