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.
