Code

function query() {

  // Figure out what base table this relationship brings to the party.
  $table_data = views_fetch_data($this->definition['base']);
  $base_field = empty($this->definition['base field']) ? $table_data['table']['base']['field'] : $this->definition['base field'];
  $this
    ->ensure_my_table();
