我在下面有一个查询，它比较两个相关的数据集，寻找一组中qty的总和与另一组不匹配的行。作为参考，一个数据集是基于PO的（MRP），一个是基于SO的（ARUN），但是它们在PO和SO编号以及材料，销售订单项等上链接。查询运行正常，但结果显示相同我所瞄准的价值观是在他们不相等的地方呼唤。我将补充说，不使用SUM的正常输出会返回两倍的行，因为每个数据集的总数分为两行（货物分开，所以有不同的容器号）。我的目标是通过使用SUM函数来摆脱它，并排除之前聚合的唯一字段。可能发生的任何想法？我已经包含了代码以及SUM和之前的结果。所以在ARUN中可以有一个唯一的集装箱号码，同样在MRP中可以有一个独特的计划行
代码：
SELECT
M.STOCK_NUMBER AS [PO_NUMBER],
M.MATERIAL,
M.MATERIAL_DESCRIPTION,
M.SIZE_LITERAL,
A.GRID_VALUE,
SUM(M.QUANTITY) AS [PO_QTY],
SUM(A.QUANTITY) AS [SO_QTY],
M.SALES_ORDER_NUMBER,
M.SALES_ORDER_ITEM_NUMBER,
M.CUSTOMER_NAME,
M.PLANNED_RECEIPT_DATE AS [ETA],
M.PLANT_CODE,
M.STOCK_TYPE
FROM VW_MRP_ALLOCATION M
JOIN VW_ARUN_NORM_NEW A
ON M.SALES_ORDER_NUMBER = A.SALES_ORDER_NUMBER
AND M.SALES_ORDER_ITEM_NUMBER = A.SALES_ORDER_ITEM_NUMBER
AND M.STOCK_NUMBER = A.SAP_PO_NUMBER
AND M.SIZE_LITERAL = A.GRID_VALUE
AND M.STOCK_TYPE = A.STOCK_TYPE
AND M.MATERIAL = A.MATERIAL_NUMBER
WHERE M.REQUIREMENT_TYPE = 'KE'
AND M.STOCK_TYPE NOT IN ('A','C')
AND M.STOCK_NUMBER IS NOT NULL
AND M.QUANTITY <> A.QUANTITY
GROUP BY M.STOCK_NUMBER,
M.MATERIAL,
M.MATERIAL_DESCRIPTION,
M.SIZE_LITERAL,
M.SALES_ORDER_NUMBER,
M.SALES_ORDER_ITEM_NUMBER,
M.CUSTOMER_NAME,
M.PLANNED_RECEIPT_DATE,
M.PLANT_CODE,
M.STOCK_TYPE,
A.GRID_VALUE
ORDER BY M.STOCK_NUMBER,
M.SIZE_LITERAL ASC
此代码导致以下（行样本）：
PO_NUMBER MATERIAL MATERIAL_DESCRIPTION SIZE_LITERAL GRID_VALUE PO_QTY SO_QTY SALES_ORDER_NUMBER SALES_ORDER_ITEM_NUMBER CUSTOMER_NAME ETA PLANT_CODE STOCK_TYPE

如果我删除SUM并将QUANTITY添加到组中，我得到：

答案 0 :(得分：2)
如果我理解你的逻辑，那么你应该在HAVING子句中比较两个总和：
SELECT
M.STOCK_NUMBER AS [PO_NUMBER],
M.MATERIAL,
M.MATERIAL_DESCRIPTION,
M.SIZE_LITERAL,
A.GRID_VALUE,
SUM(M.QUANTITY) AS [PO_QTY],
SUM(A.QUANTITY) AS [SO_QTY],
M.SALES_ORDER_NUMBER,
M.SALES_ORDER_ITEM_NUMBER,
M.CUSTOMER_NAME,
M.PLANNED_RECEIPT_DATE AS [ETA],
M.PLANT_CODE,
M.STOCK_TYPE
FROM VW_MRP_ALLOCATION M
INNER JOIN VW_ARUN_NORM_NEW A
ON M.SALES_ORDER_NUMBER = A.SALES_ORDER_NUMBER AND
M.SALES_ORDER_ITEM_NUMBER = A.SALES_ORDER_ITEM_NUMBER AND
M.STOCK_NUMBER = A.SAP_PO_NUMBER AND
M.SIZE_LITERAL = A.GRID_VALUE AND
M.STOCK_TYPE = A.STOCK_TYPE AND
M.MATERIAL = A.MATERIAL_NUMBER
WHERE
M.REQUIREMENT_TYPE = 'KE' AND
M.STOCK_TYPE NOT IN ('A','C') AND
M.STOCK_NUMBER IS NOT NULL AND
M.QUANTITY <> A.QUANTITY
GROUP BY
M.STOCK_NUMBER,
M.MATERIAL,
M.MATERIAL_DESCRIPTION,
M.SIZE_LITERAL,
M.SALES_ORDER_NUMBER,
M.SALES_ORDER_ITEM_NUMBER,
M.CUSTOMER_NAME,
M.PLANNED_RECEIPT_DATE,
M.PLANT_CODE,
M.STOCK_TYPE,
A.GRID_VALUE
HAVING
SUM(M.QUANTITY) <> SUM(A.QUANTITY)
ORDER BY
M.STOCK_NUMBER,
M.SIZE_LITERAL;
