Question

我写了一个查询以获得我需要的结果。现在我需要从该结果中根据其他一些列的分组从正值中减去负值。

我的查询：

Select ISNULL(SUM(QTYH),0) as QTY, 
ISNULL(SUM(AMTH),0)as AMT, 
PART_NBR, A_NBR, DATE 
From (
    Select PART_NBR, 
           R.A_NBR,  
        Case 
         when PO_DEBIT_CREDIT = 'H' 
         then - QTY else QTY  
         end as QTYH, 
        Case   
         when PO_DEBIT_CREDIT='H' 
         then -AMT else AMT 
         end as AMTH, 
         DATEPART(yyyy,R.DATE) as DATE, 
         PO_DEBIT_CREDIT

    FROM Receipts as R,Master as M,Vendors as t                
    WHERE R.A_NBR = 'A-10' 
    AND CAST(DATEPART(yyyy,R.DATE)as varchar) >= '2013' 
    AND CAST(DATEPART(yyyy,R.DATE)as varchar) <= '2013' 
    AND R.A_NBR = M.A_NBR 
    GROUP BY PART_NBR, 
             R.A_NBR, 
             DATEPART(yyyy,R.DATE), PO_DEBIT_CREDIT,QTY,AMT) as tb1
Group by PART_NBR, A_NBR, DATE,  PO_DEBIT_CREDIT

结果：

QTY  AMT        PART_NBR  A_NBR  Date 
=====================================   
-1   -11208.58  101       A-10   2013   
 8   89668.64   101       A-10   2013   
 3   46362.42   102       A-10   2013

我希望根据最后3列PART_NBR, A_NBR, Date将行分组在一起，并根据该分组将前2列的值加在一起。

期望的输出：

QTY  AMT        PART_NBR  A_NBR  Date       
 7   78460.06   101       A-10   2013   
 3   46362.42   102       A-10   2013

Answer 1

这可能是一个解决方案

Select ISNULL(SUM(QTYH),0) as QTY, ISNULL(SUM(AMTH),0)as AMT, PART_NBR, A_NBR, DATE From (
Select PART_NBR, R.A_NBR,  Case when PO_DEBIT_CREDIT = 'H' then - QTY else QTY  end as QTYH, Case   when PO_DEBIT_CREDIT='H' then -AMT else AMT end as AMTH, DATEPART(yyyy,R.DATE) as DATE, PO_DEBIT_CREDIT

FROM Receipts as R,Master as M,Vendors as t                
WHERE R.A_NBR = 'A-10' AND CAST(DATEPART(yyyy,R.DATE)as varchar) >= '2013' AND CAST(DATEPART(yyyy,R.DATE)as varchar) <= '2013' AND R.A_NBR = M.A_NBR 
GROUP BY PART_NBR, R.A_NBR, DATEPART(yyyy,R.DATE), PO_DEBIT_CREDIT,QTY,AMT) as tb1
Group by PART_NBR, A_NBR, DATE,  PO_DEBIT_CREDIT
Having ISNULL(SUM(QTYH),0) >= 0

Answer 2

将查询包装在子查询中并对其执行一些分组和聚合：

SELECT SUM(QTY) AS QTY, SUM(AMT) AS AMT, PART_NBR, A_NBR, [Date]
FROM
(SELECT.... YOUR EXISTING QUERY HERE)
GROUP BY PART_NBR, A_NBR, [Date]

这将按最后3列分组：PART_NBR, A_NBR, [Date]并在每组的前2列中添加值，从而添加正值或负值。

这是一个从查询输出中获取结果的示例，包含在子查询中：

CREATE TABLE #YourSubquery
    ([QTY] int, [AMT] DECIMAL(10,2), [PART_NBR] int, [A_NBR] varchar(4), [Date] int)
;

INSERT INTO #YourSubquery
    ([QTY], [AMT], [PART_NBR], [A_NBR], [Date])
VALUES
    (-1, -11208.58, 101, 'A-10', 2013),
    (8, 89668.64, 101, 'A-10', 2013),
    (3, 46362.42, 102, 'A-10', 2013)
;

SELECT SUM(QTY) AS QTY, SUM(AMT) AS AMT, PART_NBR, A_NBR, [Date]
FROM
(SELECT * FROM #YourSubquery) t
GROUP BY PART_NBR, A_NBR, [Date]

DROP TABLE #YourSubquery

<强>输出：

QTY AMT         PART_NBR    A_NBR   Date
========================================
7   78460.06    101         A-10    2013
3   46362.42    102         A-10    2013

警告：这是基于您的AMT列是数字数据类型的假设，因为您的输出显示$符号。

Answer 3

在外部选择中，您不需要使用PO_DEBIT_CREDIT进行分组。外部组应该是

"Group by PART_NBR, A_NBR, DATE"代替"Group by PART_NBR, A_NBR, DATE, PO_DEBIT_CREDIT"

因此修改后的查询是：

Select ISNULL(SUM(QTYH),0) as QTY, ISNULL(SUM(AMTH),0) as AMT, PART_NBR, A_NBR, DATE 
From (
Select PART_NBR, R.A_NBR,  Case when PO_DEBIT_CREDIT = 'H' then - QTY else QTY  end as QTYH, Case   when PO_DEBIT_CREDIT='H' then -AMT else AMT end as AMTH, DATEPART(yyyy,R.DATE) as DATE, PO_DEBIT_CREDIT

FROM Receipts as R,Master as M,Vendors as t                
WHERE R.A_NBR = 'A-10' AND CAST(DATEPART(yyyy,R.DATE)as varchar) >= '2013' AND CAST(DATEPART(yyyy,R.DATE)as varchar) <= '2013' AND R.A_NBR = M.A_NBR 
GROUP BY PART_NBR, R.A_NBR, DATEPART(yyyy,R.DATE), PO_DEBIT_CREDIT,QTY,AMT) as tb1
Group by PART_NBR, A_NBR, DATE
