Question

我需要从业务员的2列订单表中获取现金和支票金额之和。

我的桌子是这样的：

def categorical_accuracy(y_true, y_pred):
    return K.cast(K.equal(K.argmax(y_true, axis=-1),
                          K.argmax(y_pred, axis=-1)), K.floatx())

SQL：

Salesman A  Cash    21151
Salesman B  Cash    34510
Salesman C  Cash    21252
Salesman D  Cash    13356
Salesman A  Cheque  13944
Salesman B  Cheque  87368
Salesman C  Cheque  20182
Salesman D  Cheque  23862

我需要得到这样的结果：

SELECT Ca.Cash,  Cr.Credit FROM 
    (SELECT Salesman, PayMode, SUM(Collection) AS Cash
        FROM Prospect_Detail WHERE(Purpose = 'Collections') AND (PayMode = 'Cash')
        GROUP BY Salesman, PayMode) AS Ca 
        CROSS JOIN
    (SELECT Salesman, PayMode, SUM(Collection) AS Credit
        FROM Prospect_Detail WHERE(Purpose = 'Collections') AND (PayMode = 'cheque')
        GROUP BY Salesman, PayMode) Cr

Answer 1

您可以尝试以下操作。

create table #Temp (name varchar(50), collectionType varchar(10), amount int)
insert into #Temp values
('Salesman A', 'Cash', 21151),
('Salesman B', 'Cash', 34510),
('Salesman C', 'Cash', 21252),
('Salesman D', 'Cash', 13356),
('Salesman A', 'Cheque', 13944),
('Salesman B', 'Cheque', 87368),
('Salesman C', 'Cheque', 20182),
('Salesman D', 'Cheque', 23862)

SELECT name, Cash, cheque 
FROM  
(SELECT collectionType, name , amount 
    FROM #Temp) AS SourceTable  
PIVOT  
(  
SUM(amount)  
FOR collectionType IN ( Cash ,  Cheque)  
) AS PivotTable;

输出如下所示

name        Cash    cheque
--------------------------
Salesman A  21151   13944
Salesman B  34510   87368
Salesman C  21252   20182
Salesman D  13356   23862

Answer 2

要解决的建议很复杂。别理他们。只需使用条件求和。简化示例：

select Salesman, sum(case Paymode when 'Cash' then Collection else 0 end) as Cash, ...
from Prospect_Detail 
where Purpose = 'Collections'
group by Salesman 
order by Salesman;

Answer 3

可以使用PIVOT运算符来获得所需的结果：

DECLARE @tbl TABLE
(
   SalesMan varchar(50),
   PayType VARCHAR(10),
   Amount INT
)

INSERT INTO @tbl
(
    SalesMan,
    PayType,
    Amount
)
VALUES
  ('Salesman A', 'Cash',  21151)
, ('Salesman B', 'Cash',    34510)
, ('Salesman C', 'Cash',    21252)
, ('Salesman D', 'Cash',    13356)
, ('Salesman A', 'Cheque',  13944)
, ('Salesman B', 'Cheque',  87368)
, ('Salesman C', 'Cheque',  20182)
, ('Salesman D', 'Cheque',  23862)

SELECT * 
FROM 
(
    SELECT * FROM @tbl
)AS FooData
PIVOT(
    AVG(FooData.Amount)
    FOR PayType IN ([Cash], [Cheque])
) AS FooPivot

输出：

SalesMan    Cash    Cheque
Salesman A  21151   13944
Salesman B  34510   87368
Salesman C  21252   20182
Salesman D  13356   23862

Answer 4

您可以通过以下方式旋转表格

With c as(
SELECT Salesman
     , Paymode
     , Sum(Collection) AS Cheque
FROM 
    Prospect_Detail
GROUP BY 
      Salesman
    , Paymode
)
Select Salesman
      ,[Cash]
      ,[Cheque] 
From C
Pivot(
    Sum(Cheque)
    For Paymode in ([Cash],[Cheque]) 
) as pvt;
