Remarks
To get DefaultConstraint object properties, users can be members of the public fixed server role.
To set DefaultConstraint 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 default constraint, users must have ALTER permission on the parent table or be a member of the db_owner fixed database role.
