在 PIVOT 中将子值分组为一组

Question

请考虑这种情况：

我们有存储订单规格的订单 table。这些规范之一是货币。我在 table 中有几种货币，例如 美元、欧元、英镑、日元、迪拉姆、里亚尔、卢比 。 美元、欧元、英镑是主要货币。我想在我的查询中将其他人分组为一组。我如何使用 PIVOT 命令来做到这一点？

我想创建这样的结果：

ProductCategory        Dollar      Euro       Pound      Others
---------------------------------------------------------------
P1                     1000        2000        500        880
P2                     1200        100         200        750
P3                     1900        8000        700        640
P4                     1500        500         1000       270
P5                     2000        1700        1200       1000

谢谢

更新 1)

我的来源 table 是这样的：

ProductCategory   Currency     Amount       
----------------------------------------
P1                Dollar       100         
P2                Euro         500    
P3                Dollar       100      
P4                Yen          200       
P1                Dollar       100       
P3                Rupee        50        
...

declare @tbl  table
(
    Product   nvarchar(50),
    Cur       nvarchar(50),
    Amount    int
)


insert into @tbl values
('p1', 'dollar',100),
('p2', 'euro',100),
('p3', 'pound',100),
('p1', 'a',100),
('p1', 'b',100),
('p2', 'c',100),
('p3', 'dollar',100),
('p3', 'euro',100),
('p2', 'euro',100),
('p2', 'euro',100),
('p1', 'j',100)


SELECT pv.Product
    ,ISNULL(pv.Dollar,0) AS [Dollar]
    ,ISNULL(pv.Euro,0) AS [Euro]
    ,ISNULL(pv.Pound,0) AS [Pound]
    ,ISNULL(pv.Other,0) AS [Other]
FROM (
SELECT *
    ,CASE
        WHEN [Cur] NOT IN ('dollar','euro','pound') THEN 'Other'
        ELSE [Cur]
    END AS [newCurrency] 
FROM @tbl
)as a
PIVOT (
    SUM([Amount]) 
    FOR [newCurrency] IN ([dollar],[euro],[pound],[Other])
)as pv

得到这个结果：

Answer 1

试试这个查询，您可以根据产品对其他货币求和。

select  productCategory, 
        sum(dollar), 
        sum(euro),
        sum(pound), 
        sum(others) 
from order 
group by productCategory

希望对您有所帮助。

Answer 2

试试这个查询

 SELECT pv.ProductCategory
    ,ISNULL(pv.Dollar,0) AS [Dollar]
    ,ISNULL(pv.Euro,0) AS [Euro]
    ,ISNULL(pv.Pound,0) AS [Pound]
    ,ISNULL(pv.Other,0) AS [Other]
FROM (
    SELECT *
        ,CASE
            WHEN [Currency] NOT IN ('Dollar','Euro','Pound') THEN 'Other'
            ELSE [Currency]
        END AS [newCurrency] 
    FROM #tmp
)as a
PIVOT (
    MAX([Amount]) 
    FOR [newCurrency] IN ([Dollar],[Euro],[Pound],[Other])
)as pv

Answer 3

你快到了。在更新 2 中稍微修改了您的查询。我认为这就是您想要的。

declare @tbl  table
(
    Product   nvarchar(50),
    Cur       nvarchar(50),
    Amount    int
)

insert into @tbl values
('p1', 'dollar',100),
('p2', 'euro',100),
('p3', 'pound',100),
('p1', 'a',100),
('p1', 'b',100),
('p2', 'c',100),
('p3', 'dollar',100),
('p3', 'euro',100),
('p2', 'euro',100),
('p2', 'euro',100),
('p1', 'j',100)

SELECT pv.Product
    ,sum(ISNULL(pv.Dollar,0)) AS [Dollar]
    ,sum(ISNULL(pv.Euro,0)) AS [Euro]
    ,sum(ISNULL(pv.Pound,0)) AS [Pound]
    ,sum(ISNULL(pv.Other,0)) AS [Other]
FROM (
SELECT *
    ,CASE
        WHEN [Cur] NOT IN ('dollar','euro','pound') THEN 'Other'
        ELSE [Cur]
    END AS [newCurrency] 
FROM @tbl
)as a
PIVOT (
    SUM([Amount]) 
    FOR [newCurrency] IN ([dollar],[euro],[pound],[Other])
)as pv
group by product
