ORA-00913：“值太多”我不确定应该在哪里找到函数和子查询

如何解决ORA-00913：“值太多”我不确定应该在哪里找到函数和子查询

我应该在结果中看到这些列：“工作ID，位置ID，位置名称，销售类别ID，销售类别描述，工作承诺日期的时间ID，最后装运日期的时间ID，订单数量工作中，工作承诺日期后的发货数量总和，上次发货日期与承诺日期之间的工作日差额。”

但是我遇到这个错误ORA-00913：“值太多”。 我不确定应该在哪里找到函数和子查询！ 我将在下面分享我的查询和功能。 预先非常感谢您的帮助。

注意：X1别名的功能和选择查询正常工作。

**function:

  else
    return  difference ;
  end if;
END;

解决方法

子查询必须仅返回一个值，而不是一堆值（如您的值）。这个：

(SELECT W_SUB_JOB_F.JOB_ID,MAX(actual_ship_Date)   AS Last_Shipment_Date,SUM ( actual_Quantity ) AS SumDelayShipQty
   FROM W_JOB_SHIPMENT_F,W_SUB_JOB_F,W_Job_F
   WHERE W_SUB_JOB_F.SUB_JOB_ID = W_JOB_SHIPMENT_F.SUB_JOB_ID
     AND W_Job_F.Job_Id = W_SUB_JOB_F.JOB_ID
     And Actual_Ship_Date > Date_Promised
   Group By W_Sub_Job_F.Job_Id )

也许您应该将这两个表正确地连接到主查询中的其余表。
