示例1: _addGetJoinAs

 /**
  * If a left join is needed by the <data> $data element:
  * Adds if not yet added a JOIN statement for the <data> element $data
  * and returns the table AS alias for accessing the corresponding table.
  * Otherwise returns NULL.
  *
  * @param  SimpleXmlElement  $data
  * @param  array             $subFormula  For process_reverse_sql_field ONLY (if we decide to use): SQL conditions in array which are imploded by AND for the merge
  * @return string|null                    Name of table alias (a to z) if the <data> element required a left join.
