주의

To get ForeignKey object properties, users can be a member of the public fixed server role.

To set ForeignKey object properties, users must have ALTER permission on the parent table or be a member of the db_owner fixed database role.

To create or drop a foreign key, users must have ALTER permission on the parent table or be a member of the db_owner fixed database role.
