SQL查詢到每月逐項日銷售額

Question

在我的銷售表中，列出的是一個物業中特定租戶的每日銷售額。

使用此代碼，我能夠列出或選擇租客的每日銷售額，根據Property的分組進行總結。

SELECT date , location , SUM(a.gsc) Sales 
FROM SalesTable 
WHERE (date BETWEEN '01/01/2015' AND '12/31/2015') 
     and (location = 'Property1') 
GROUP BY location , date 
ORDER BY location, date 

而結果是這樣的

Date   Location  Sales 
01/01/2015 Property1 10,000 
01/02/2015 Property1 20,000 
. 
. 
. 
12/31/2015 Property1 15,000 

我要完成作爲最終輸出的就是讓有天日期的第一行和月如的結果以表格形式列。 請參閱示例輸出以獲得進一步說明。

Date January    February    
     Date Day Sales Date Day Sales 
1  1-Jan Fri 10,000 1-Feb Mon 9,000 
2  2-Jan Sat 20,000 2-Feb Tue 10,000 
3  .  . .  .  . . 
4  .  . .  .  . . 
5  .  . .  .  . . 
6  
7 
8 
. 
. 
. 
. 
. 
31 

這是我試過

SELECT date , location , SUM(a.gsc) Sales 
INTO #TempTable1 
FROM SalesTable 
WHERE (date BETWEEN '01/01/2015' AND '12/31/2015') 
      and (location = 'Property1') 
GROUP BY location , date 
ORDER BY location, date 



    SELECT months.number, tenants.locationd , tenants.location  
     ,(case when (t.DATE) = 1 then t.gsc end) as 'January' 
     ,(case when (t.DATE) = 2 then t.gsc end)) as 'February' 
     (case when year(t.DATE) = 3 then t.gsc end) as 'March' 

     FROM 
      (  
        SELECT Number 
        FROM master..spt_values 
        WHERE Type = 'P' and Number between 1 and 31 
      ) months 
      CROSS JOIN 
      (  --12 Month Name will be cross joined sa selected tenant/s 
        SELECT DISTINCT locationd , location 
        FROM #AMRDSR1 
      ) tenants  

    LEFT JOIN #AMRDSR1 t 
    ON months.number = datepart(day,t.date) and tenants.location = t.location 
    GROUP BY months.number, tenants.locationd , tenants.location , t.date, t.gsc 
    ORDER BY tenants.locationd , datepart(day,t.date) 

我已建議使用支點，但是那是相當新的給我，似乎是很複雜的，如果有辦法只需使用TSQL就好了。

希望得到您的專家建議。

謝謝！

-- assuming you only show one year of data at a time 

; with 
-- first get sales by date and the day of month and also month etc. 
data 
(
    SELECT [date] , SUM(a.gsc) AS Sales, 
     datepart(day, [date]) as [Day], 
     datepart(month, [date]) as [Month], 
     left(datename(weekday, [date]),3) as [WeekDay] 
    FROM SalesTable a 
    WHERE ([date] BETWEEN '01/01/2015' AND '12/31/2015') 
    and (location = 'Property1') 
    GROUP BY [date] 
) 
-- Now the "pivoting" using CASE WHEN .... with aggregate function 
SELECT [Day], 
     MAX(CASE WHEN [Month] = 1 THEN [date] END) as Date_Jan, 
     MAX(CASE WHEN [Month] = 1 THEN [WeekDay] END) as WeekDay_Jan, 
     SUM(CASE WHEN [Month] = 1 THEN [Sales] END) as Sales_Jan, 
     MAX(CASE WHEN [Month] = 2 THEN [date] END) as Date_Feb, 
     MAX(CASE WHEN [Month] = 2 THEN [WeekDay] END) as WeekDay_Feb, 
     SUM(CASE WHEN [Month] = 2 THEN [Sales] END) as Sales_Feb, 
     . . . . 
FROM data 
GROUP BY [Day]
