透视表不分组结果如预期

Question

我使用SQL Server 2012.我有两个表，请参见下面

Table 1 (Region_Strat) 

STRAT SALES_P COMM 
EU  Bob  AC 
EU  Dave  AC 
NA  John  JP 
GB  Mike  AC 


Table 2 (Sales_Records) 

SALES_P AMT SHOP 
Bob  5  ABC 
Bob  10 DEF 
Bob  3  GHI 
Dave  12 ABC 
John  3  DEF 
Mike  11 LIK 

我有一个观点叫vw_sales（存储视图这不能改变），它基本上是增加从Region_Strat表到Sales_Records表的STRAT列向我提供下表。

SALES_P AMT SHOP STRAT 
Bob  5  ABC  EU  
Bob  10 DEF  EU  
Bob  3  GHI  EU  
Dave  12 ABC  EU  
John  3  DEF  NA  
Mike  11 LIK  GB 

这很好。接下来，我尝试创建一个交换表（它运行但不会给我我需要的结果）。我的查询是

SELECT SHOP, [EU],[NA],[GB] 
INTO MY_DB.dbo.TEMP 
FROM 
(SELECT SALES.SHOP, cast(SALES.Amt as bigint) AS SumOfAmt, Region.COMM, Region.STRAT 
    FROM MY_DB.dbo.vw_sales AS SALES JOIN MY_DB.dbo.Region_Strat AS Region ON 
    SALES.SALES_P = Region.SALES_P 
    WHERE Region.COMM in ('AC','JP')) tbl 
pivot 
(sum(SumOfAmt) for STRAT IN([EU],[NA],[GB])) pvt order by SHOP 

结果，我希望看到，

SHOP EU NA GB 
ABC 17 null null  
DEF 10 3  null 
GHI 3  null null 
LIK null null 11 

但是我看到的结果是DEF如下图所示两次店。

SHOP EU NA GB 
DEF 10 null null  
DEF null 3  null 

如何更改我更改我的查询，以便DEF显示在一行上？

Answer 1

试试这个：

SELECT SHOP, [EU],[NA],[GB] INTO MY_DB.dbo.TEMP 
FROM 
(SELECT SALES.SHOP, cast(SALES.Amt as bigint) AS SumOfAmt, Region.STRAT 
    FROM MY_DB.dbo.vw_sales AS SALES 
    JOIN MY_DB.dbo.Region_Strat AS Region ON SALES.SALES_P = Region.SALES_P 
    WHERE Region.COMM in ('AC','JP') 
) tbl 
pivot (sum(SumOfAmt) for STRAT IN([EU],[NA],[GB])) pvt 
order by SHOP
