    [ CASCADE ]
    [ AS <database_principal> ]

<database_principal> ::=

    | Application_role 
    | Database_user_mapped_to_Windows_User 
    | Database_user_mapped_to_Windows_Group 
    | Database_user_mapped_to_certificate 
    | Database_user_mapped_to_asymmetric_key 
    | Database_user_with_no_login

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 will be 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
