    [ AS <database_principal> ]  
  
<database_principal> ::=   
        Database_user

    | Database_user_mapped_to_Windows_User   
    | Database_user_mapped_to_Windows_Group

    | Database_user_mapped_to_asymmetric_key

Arguments

permission
Specifies a permission that can be denied 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 denied. 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.

TO <database_principal>
Specifies the principal to which the permission is being denied.

CASCADE
Indicates that the permission being denied is also denied to other principals to which it has been granted by this principal.

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

Remarks

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

Important

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 denied on a type are listed in the following table, together with the more general permissions that include them by implication.

Type permission Implied by type permission Implied by schema permission
CONTROL CONTROL CONTROL
EXECUTE CONTROL EXECUTE
REFERENCES CONTROL REFERENCES
TAKE OWNERSHIP CONTROL CONTROL
VIEW DEFINITION CONTROL VIEW DEFINITION

Permissions

Requires CONTROL permission on the type. If you use the AS clause, the specified principal must own the type on which permissions are being denied.

Examples

The following example denies VIEW DEFINITION permission with CASCADE on the user-defined type PhoneNumber to the KhalidR. PhoneNumber is located in schema Telemarketing.

DENY VIEW DEFINITION ON TYPE::Telemarketing.PhoneNumber   
    TO KhalidR CASCADE;  
GO
