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.

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;
