复杂的组SQL查询

Question

这里是我的查询和结果;

select 
DATEADD(dd, DATEDIFF(dd, 0, PostDate), 0) as Date, 
Stores.Name StoreName, 
SUM(PosCash + PosCredit + PosBillCash + PosBillCredit) as Revenue 
from StoreRevenue 
inner join Stores on Stores.ID = StoreRevenue.StoreID 
group by DATEADD(dd, DATEDIFF(dd, 0, PostDate), 0), Stores.Name 

结果：http://prntscr.com/zaele

我想创建一个表（结果），必须是按日期和商店名称组。

Date, Avcılar Mağaza, Ataşehir Mağaza 
2013-03-04, 150, 200 
2013-03-05, 200, 250 
2013-03-06, 300, 150 

行子组（这些的：2013年3月4日，150，200）的日期和收入我想那种结果 的每个门店 的我也曾尝试“支点”在SQL中，但它不适用于我

对不起，我的英语。 -Thanks

Answer 1

可以使用PIVOT函数从行变换的数据列：

select * 
from 
(
    select 
    DATEADD(dd, DATEDIFF(dd, 0, PostDate), 0) as Date, 
    Stores.Name StoreName, 
    (PosCash + PosCredit + PosBillCash + PosBillCredit) as Revenue 
    from StoreRevenue 
    inner join Stores 
    on Stores.ID = StoreRevenue.StoreID 
) d 
pivot 
(
    sum(Revenue) 
    for StoreName in ([Avcılar Mağaza], [Ataşehir Mağaza]..) 
) piv; 

或者你可以使用聚合函数与CASE：

select DATEADD(dd, DATEDIFF(dd, 0, PostDate), 0) as Date, 
    sum(case when Stores.Name = 'Avcılar Mağaza' 
     then PosCash + PosCredit + PosBillCash + PosBillCredit end) as [Avcılar Mağaza], 
    sum(case when Stores.Name = 'Ataşehir Mağaza' 
     then PosCash + PosCredit + PosBillCash + PosBillCredit end) as [Ataşehir Mağaza] 
from StoreRevenue 
inner join Stores 
    on Stores.ID = StoreRevenue.StoreID 
group by DATEADD(dd, DATEDIFF(dd, 0, PostDate), 0) 

如果你有一个未知的数字fo店，那么你可以SE动态SQL：

DECLARE @cols AS NVARCHAR(MAX), 
    @query AS NVARCHAR(MAX) 

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(name) 
        from Stores 
      FOR XML PATH(''), TYPE 
      ).value('.', 'NVARCHAR(MAX)') 
     ,1,1,'') 

set @query = 'SELECT Date, ' + @cols + ' 
      from 
      (
       select 
        DATEADD(dd, DATEDIFF(dd, 0, PostDate), 0) as Date, 
        Stores.Name StoreName, 
        (PosCash + PosCredit + PosBillCash + PosBillCredit) as Revenue 
       from StoreRevenue 
       inner join Stores 
        on Stores.ID = StoreRevenue.StoreID 
      ) x 
      pivot 
      (
       sum(Revenue) 
       for StoreName in (' + @cols + ') 
      ) p ' 

execute(@query)

试试这个：

WITH CTE 
AS 
(
    select 
     DATEADD(dd, DATEDIFF(dd, 0, PostDate), 0) as Date, 
     Stores.Name StoreName, 
     PosCash + PosCredit + PosBillCash + PosBillCredit as Revenue 
    from StoreRevenue 
    inner join Stores on Stores.ID = StoreRevenue.StoreID 
) 
SELECT * 
FROM CTE AS c 
PIVOT 
(
    SUM(Revenue) 
    FOR StoreName IN ([Avcılar Mağaza], [Ataşehir Mağaza], ...) 
) AS p
