Arguments

  • permission

  • 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 about 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.
