1. var prevRow=previous_result.getRows();//獲取上一個傳遞的結果,資料庫中查詢的結果集
2. if (prevRow == null &&(prevRow.size()=0))
3. {
4. false;
5. }else{
6. parent_job.setVariable("tables", prevRow);//ArrayList儲存表名變數，以陣列形式儲存入table1，table2
7. parent_job.setVariable("size", prevRow.size());//儲存執行表的總數量
8. parent_job.setVariable("i"
   ,new Number(0));//迴圈控制變數

10. parent_job.setVariable("id", prevRow.get(0).getString("hosp","hosp"));//根據欄位名獲取值
