    [ WITH GRANT OPTION ]
    [ AS <database_principal> ]

<database_principal> ::= 
        Database_user 
    | Database_role 
    | 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 granted 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 granted. 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 granted.

WITH GRANT OPTION: Indicates that the principal will also be given the ability to grant the specified permission to other principals.

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

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

The grantor (or the principal specified with the AS option) must have either the permission itself with GRANT OPTION, or a higher permission that implies the permission being granted.

If you are using the AS option, the following additional requirements apply.

AS	Additional permission required
Database user	IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a Windows login	IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a Windows group	Membership in the Windows group, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a certificate	Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to an asymmetric key	Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user not mapped to any server principal	IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database role	ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Application role	ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.

Examples

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

GRANT VIEW DEFINITION ON TYPE::Telemarketing.PhoneNumber 
    TO KhalidR WITH GRANT OPTION;
GO
