public function __clone() {

  // On cloning, also clone the dependent objects. However, we do not
  // want to clone the database connection object as that would duplicate the
  // connection itself.
  $this->where = clone $this->where;
  $this->having = clone $this->having;
  foreach ($this->union as $key => $aggregate) {
    $this->union[$key]['query'] = clone $aggregate['query'];
