要顯示不同的值，並使用SQL服務器求和值

Question

在下面的代碼中，我有一個查詢，我想顯示這樣的值。我想要顯示不同的taxcalculation和總價格的基礎上獨特taxcalculation.Pls幫助我做到這一點。

發票詳細信息表：

TaxCalculation TotalPrice

0.00   500 
0.00   750 
1.00   980 
2.00   400 

預期結果：

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

這是我只是用你的查詢作爲子查詢

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
