function get_join() {
  // get the join from this table that links back to the base table.
  // Determine the primary table to seek
  if (empty($this->query->relationships[$this->relationship])) {
    $base_table = $this->query->base_table;
  }
  else {
    $base_table = $this->query->relationships[$this->relationship]['base'];
  }

  $join = views_get_table_join($this->table, $base_table);
  if ($join) {
    return clone $join;
