  }
  $this->definition['extra'][] = array(
    'field' => 'fid',
    'value' => $flag->fid,
    'numeric' => TRUE,
  );
  if (!empty($this->options['required'])) {

    // Unfortunately, we may have zeros in our table, so having
    // parent::query() do INNER JOIN doesn't suffice. We need to filter these
    // zeros out.
    // @todo Make sure zero records aren't written in the first place, and
    // remove this code.
    $this->definition['extra'][] = array(
      'field' => 'count',
      'operator' => '>',
      'value' => '0',
      'numeric' => TRUE,
    );
