<database_principal> ::= Database_user

permission

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

ON TYPE :: [ schema_name ] . type_name

Specifies the type on which the permission is being revoked. 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.

Important noteImportant

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 noteCaution

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.

A type is a schema-level securable contained by the schema that is its parent in the permissions hierarchy.

Important noteImportant

GRANT, DENY, and REVOKE permissions do not apply to system types. User-defined types can be granted permissions. For more information about user-defined types, see Working with User-Defined Types in SQL Server.

The most specific and limited permissions that can be revoked on a type are listed in the following table, together with the more general permissions that include them by implication.

VIEW DEFINITION

Requires CONTROL permission on the type. If you use the AS clause, the specified principal must own the type.

The following example revokes VIEW DEFINITION permission on the user-defined type PhoneNumber from the user KhalidR. The CASCADE option indicates that VIEW DEFINITION permission will also be revoked from principals to which KhalidR granted it. PhoneNumber is located in schema Telemarketing.

REVOKE VIEW DEFINITION ON TYPE::Telemarketing.PhoneNumber 
    FROM KhalidR CASCADE;
GO
