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 on User-Defined Types, see Working with User-Defined Types in SQL Server.

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