如何解决此错误“无法对包含聚合或子查询的表达式执行聚合函数”

SELECT        tblPR.PRNO, tblPRMaterial.PRMaterialCode, ISNULL(SUM(DISTINCT tblPRMaterial.PRReqdQty - SUM(tblPOFromPR.Qty)), tblPRMaterial.PRReqdQty) AS PR_Qty
FROM            tblPR INNER JOIN
                         tblPRMaterial ON tblPR.PRNO = tblPRMaterial.PRNO INNER JOIN
                         tblMaterial ON tblPRMaterial.PRMaterialCode = tblMaterial.MaterialCode LEFT OUTER JOIN
                         tblPOFromPR ON tblPRMaterial.PRNO = tblPOFromPR.PRNO AND tblPRMaterial.PRMaterialCode = tblPOFromPR.MaterialCode
WHERE        (tblPR.PRStatus = 1) AND (tblPRMaterial.PRItemStatus = 0) AND (tblPR.PRType = 'PR') AND (tblPR.PRNO = 56548)
GROUP BY tblPR.PRNO, tblPRMaterial.PRMaterialCode, tblPRMaterial.PRReqdQty
ORDER BY tblPR.PRNO

Answer 1

您可以尝试以下操作-您需要在isull函数中添加sum(tblPRMaterial.PRReqdQty)

    SELECT tblPR.PRNO, tblPRMaterial.PRMaterialCode, 
   coalesce(SUM(DISTINCT tblPRMaterial.PRReqdQty) - SUM(tblPOFromPR.Qty), 
   sum(tblPRMaterial.PRReqdQty)) AS PR_Qty
    FROM            tblPR INNER JOIN
                             tblPRMaterial ON tblPR.PRNO = tblPRMaterial.PRNO INNER JOIN
                             tblMaterial ON tblPRMaterial.PRMaterialCode = tblMaterial.MaterialCode LEFT OUTER JOIN
                             tblPOFromPR ON tblPRMaterial.PRNO = tblPOFromPR.PRNO AND tblPRMaterial.PRMaterialCode = tblPOFromPR.MaterialCode
    WHERE        (tblPR.PRStatus = 1) AND (tblPRMaterial.PRItemStatus = 0) AND (tblPR.PRType = 'PR') AND (tblPR.PRNO = 56548)
    GROUP BY tblPR.PRNO, tblPRMaterial.PRMaterialCode
    ORDER BY tblPR.PRNO

Answer 2

选择和分组依据中的列数必须相同

    SELECT  tblPR.PRNO,
 tblPRMaterial.PRMaterialCode, 
ISNULL(SUM(tblPRMaterial.PRReqdQty) - SUM(tblPOFromPR.Qty), sum(tblPRMaterial.PRReqdQty)) AS PR_Qty
    FROM            tblPR INNER JOIN
                             tblPRMaterial ON tblPR.PRNO = tblPRMaterial.PRNO INNER JOIN
                             tblMaterial ON tblPRMaterial.PRMaterialCode = tblMaterial.MaterialCode LEFT OUTER JOIN
                             tblPOFromPR ON tblPRMaterial.PRNO = tblPOFromPR.PRNO AND tblPRMaterial.PRMaterialCode = tblPOFromPR.MaterialCode
    WHERE        (tblPR.PRStatus = 1) AND (tblPRMaterial.PRItemStatus = 0) AND (tblPR.PRType = 'PR') AND (tblPR.PRNO = 56548)
    GROUP BY tblPR.PRNO, tblPRMaterial.PRMaterialCode
    ORDER BY tblPR.PRNO,tblPRMaterial.PRMaterialCode

因为Aggregate上不能包含另一个Aggregate表达式。.也许您可以使用显式来执行Sum操作。

SELECT 
  PRNO,
  PRMaterialCode,
  ISNULL(SUM(SUM_PR), PRReqdQty) AS PR_QTY
FROM
(SELECT        
  tblPR.PRNO, 
  tblPRMaterial.PRMaterialCode,
  tblPRMaterial.PRReqdQty, 
  DISTINCT tblPRMaterial.PRReqdQty - SUM(tblPOFromPR.Qty) AS SUM_PR
FROM 
  tblPR 
  INNER JOIN tblPRMaterial ON tblPR.PRNO = tblPRMaterial.PRNO 
                           AND (tblPRMaterial.PRItemStatus = 0)
  INNER JOIN tblMaterial ON tblPRMaterial.PRMaterialCode = tblMaterial.MaterialCode 
  LEFT OUTER JOIN tblPOFromPR ON tblPRMaterial.PRNO = tblPOFromPR.PRNO 
                              AND tblPRMaterial.PRMaterialCode = tblPOFromPR.MaterialCode
WHERE 
  (tblPR.PRStatus = 1) 
  AND (tblPR.PRType = 'PR') 
  AND (tblPR.PRNO = 56548)
GROUP BY 
  tblPR.PRNO, 
  tblPRMaterial.PRMaterialCode, 
  tblPRMaterial.PRReqdQty
ORDER BY 
  tblPR.PRNO) AS Derived_Table
GROUP BY
  PRNO,
  PRMaterialCode,
  PRReqdQty
ORDER BY
  PRNO
