Question

在下面的代码中，我有一个查询，我想显示像这样的值。我想显示不同的税收计算，并根据独特的税收计算总价格的总和。请帮助我这样做。

发票明细表：

TaxCalculation TotalPrice

 0.00            500
 0.00            750
 1.00            980
 2.00            400

预期结果：

TaxCalculation TotalPrice

 0.00            1250
 1.00            980
 2.00            400



SELECT DISTINCT CONVERT(VARCHAR(10), I.CreatedOn, 105) AS InvoiceDate
    ,INVD.Interest
    ,CASE 
        WHEN Count(INVD.TaxCalculation) OVER (PARTITION BY INVD.TaxCalculation) > 1
            THEN SUM(Isnull((INVD.TotaPrice), 0.00))
        ELSE Isnull((INVD.TotaPrice), 0.00)
        END VATAMOUNT
    ,INVD.TaxCalculation
    ,INVD.TotaPrice
FROM Invoice I
LEFT OUTER JOIN Customer C 
    ON C.CustomerID = I.CustomerID
LEFT OUTER JOIN InvoiceDetail INVD 
    ON INVD.InvoiceID = I.InvoiceID
LEFT OUTER JOIN Locations L 
    ON L.LocationID = I.LocationID
LEFT OUTER JOIN LocationProductMap LPM 
    ON LPM.ProductID = INVD.ProductID
LEFT OUTER JOIN OrderForm O 
    ON O.OrderFormID = I.OrderFormID
LEFT OUTER JOIN Product P 
    ON P.ProductID = INVD.ProductID
LEFT OUTER JOIN UnitType U 
    ON U.UnitTypeID = P.UnitTypeID
WHERE I.InvoiceID = @i_InvoiceID
    AND LPM.LocationID = I.LocationID
GROUP BY I.TotalPrice
    ,CONVERT(VARCHAR(10), I.CreatedOn, 105)
    ,INVD.Interest
    ,INVD.TaxCalculation
    ,INVD.TotaPrice

Answer 1

这是我将查询用作子查询的地方

SELECT
    A.TaxCalculation 
  , SUM(A.TotaPrice) AS TotalPrice
FROM
(
  SELECT DISTINCT 
      CONVERT(VARCHAR(10), I.CreatedOn, 105) AS InvoiceDate
      , INVD.Interest
      , CASE 
          WHEN Count(INVD.TaxCalculation) OVER (PARTITION BY INVD.TaxCalculation) > 1
              THEN SUM(Isnull((INVD.TotaPrice), 0.00))
          ELSE Isnull((INVD.TotaPrice), 0.00)
          END VATAMOUNT
      , INVD.TaxCalculation
      , INVD.TotaPrice
  FROM Invoice I
  LEFT JOIN Customer C
      ON C.CustomerID = I.CustomerID
  LEFT JOIN InvoiceDetail INVD
      ON INVD.InvoiceID = I.InvoiceID
  LEFT JOIN Locations L
      ON L.LocationID = I.LocationID
  LEFT JOIN LocationProductMap LPM
      ON LPM.ProductID = INVD.ProductID
  LEFT JOIN OrderForm O
      ON O.OrderFormID = I.OrderFormID
  LEFT JOIN Product P
      ON P.ProductID = INVD.ProductID
  LEFT JOIN UnitType U
      ON U.UnitTypeID = P.UnitTypeID
  WHERE I.InvoiceID = @i_InvoiceID
      AND LPM.LocationID = I.LocationID
  GROUP BY I.TotalPrice
      , CONVERT(VARCHAR(10), I.CreatedOn, 105)
      , INVD.Interest
      , INVD.TaxCalculation
      , INVD.TotaPrice
) AS A
GROUP BY A.TaxCalculation

Answer 2

以下查询给出了预期结果。

从税收

中选择不同税，来自发票组的总和（价格）

有关详细信息，请参阅以下链接：

如果这不是预期的答案，请告诉我税务计算和定义的总价格的数据类型。

谢谢。

显示不同的值并使用sql server对值进行求和
