SQL Server PIVOT - Mehrere Aggregate

Question

die folgende Ergebnismenge Gegeben:

---------------------------------------------------------
CustomerID  Service  TransType  SubTotal   Tax   NetTotal
---------------------------------------------------------
106            A        CREDIT     12.52     -      12.52 
106            A        CREDIT     10.07     -      10.07
106            B        CREDIT      2.00     -       2.00
106            C        REMOTE      5.99     -       5.99
106            C        CREDIT      5.99     -       5.99
106            C        CREDIT      3.99  0.30       3.69
106            C        CREDIT      5.99  0.30       5.69
106            D        CREDIT      5.99     -       5.99
---------------------------------------------------------

Beachten Sie, dass NetTotal = SubTotal - Steuer

Bitte helfen Sie mir berechnen Summe (SubTotal), sum (Tax) und sum (NetTotal), zusammen mit lenkt Transtype wie folgt:

--------------------------------------------------------------------------
CustomerID  Service  Cash  Check  Credit  Remote  SubTotal   Tax  NetTotal
--------------------------------------------------------------------------
106            A        0      0   22.59       0     22.59     0     22.59   
106            B        0      0    2.00       0      2.00     0      2.00    
106            C        0      0   15.97    5.99     21.96  0.60     21.36    
106            D        0      0    5.99       0      5.99     0      5.99    
--------------------------------------------------------------------------

Wenn ich nur 1 Spalte habe zusammengefasst werden, um es vorwärts gerade sein würde PIVOT, aber ich bin nicht sicher, wie die drei Aggregate erhalten - für SubTotal, Steuern und NetTotal.

Vielen Dank für Ihre Hilfe!

Answer 1

Dies kann ohne PIVOT getan werden:

SELECT 
  CustomerID
, [Service]
, Cash = SUM(case when TransType='CASH' then SubTotal else 0 end)
, [Check] = SUM(case when TransType='CHECK' then SubTotal else 0 end)
, Credit = SUM(case when TransType='CREDIT' then SubTotal else 0 end)
, [Remote] = SUM(case when TransType='REMOTE' then SubTotal else 0 end)
, SubTotal = SUM(SubTotal)
, Tax = SUM(Tax)
, NetTotal = SUM(NetTotal)
FROM YourTable
GROUP BY CustomerId, [Service]

Mit PIVOT, wird es wesentlich komplexer. Der einfachste Weg, die ich denken kann ist SubTotal, Steuer, und NetTotal in einer anderen Abfrage zu berechnen, und kombiniert dann die Abfragen mit einem Join. Beispiel unten; die Abfrage einfach zu halten, habe ich Bargeld- und Scheck verworfen.

SELECT  
  a.CustomerId
, a.Service
, Credit = a.Credit
, [Remote] = a.[Remote]
, SubTotal = SUM(b.SubTotal)
, Tax = SUM(b.Tax)
, NetTotal = SUM(b.NetTotal)
FROM (
    SELECT 
      CustomerId
    , [Service]
    , Credit = SUM(Credit)
    , [Remote] = SUM([Remote])
    FROM YourTable a
    PIVOT
    (
        SUM(SubTotal) FOR [TransType] IN ([Credit],[Remote])
    ) pvt
    GROUP BY CustomerId, [Service]
) a
INNER JOIN YourTable b 
    ON a.CustomerID = b.CustomerID 
    AND a.[Service] = b.[Service]
GROUP BY a.CustomerId, a.[Service], a.Credit, a.[Remote]

Answer 2

Haben Sie versucht, so etwas wie das?

DECLARE @Table TABLE(
        CustomerID INT,
        [Service] VARCHAR(MAX),
        TransType VARCHAR(MAX),
        SubTotal FLOAT,
        Tax FLOAT,
        NetTotal FLOAT
)

INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'A', 'CREDIT', 12.52, 0 , 12.52
INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'A', 'CREDIT', 10.07, 0 , 10.07
INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'B', 'CREDIT', 2, 0 , 2
INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'C', 'REMOTE', 5.99, 0 , 5.99
INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'C', 'CREDIT', 5.99, 0 , 5.99
INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'C', 'CREDIT', 3.99, 0.3 , 3.69
INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'C', 'CREDIT', 5.99, 0.3 , 5.69
INSERT INTO @Table (CustomerID,[Service],TransType,SubTotal,Tax,NetTotal)
SELECT 106, 'D', 'CREDIT', 5.99, 0 , 5.99

SELECT  Pivots.CustomerID,
        Pivots.[Service],
        Pivots.Cash,
        Pivots.[Check],
        Pivots.Credit,

                                [Service],
                                TransType,
                                SubTotal
                        FROM    @Table
                    ) sub
                    PIVOT
                    (
                        SUM(SubTotal)
                        FOR [TransType] IN ([Cash],[Check],[Credit],[Remote])
                    ) pvt
            ) Pivots INNER JOIN
            (                       
                SELECT  CustomerID,
                        [Service],
                        SUM(SubTotal) SumSubTotal,
                        SUM(Tax) SumTax,
                        SUM(NetTotal) SumNetTotal
                FROM    @Table
                GROUP BY CustomerID,
                        [Service]
            ) Total ON  Pivots.CustomerID = Total.CustomerID
                    AND Pivots.[Service] = Total.[Service]
