1.JavaScript
var prevRow=previous_result.getRows();//擷取上一個傳遞的結果,資料庫中查詢的結果集
if (prevRow == null &&(prevRow.size()=0))
{
false;
}else{
parent_job.setVariable("tables", prevRow);//ArrayList存儲表名變量,以數組形式儲存入table1,table2
parent_job.setVariable("size", prevRow.size());//存儲執行表的總數量
parent_job.setVariable("i",new Number(0));//循環控制變量
parent_job.setVariable("k",0);
parent_job.setVariable("id", prevRow.get(0).getString("hosp","hosp"));//根據字段名擷取值
parent_job.setVariable("hospname", prevRow.get(0).getString("hospname","hospname"));
