SQLクエリから月間毎月売上高

Question

私のSales Tableには、1つのProperty内の特定のテナントの日々の売上高が表示されます。

このコードを使用して、プロパティのグループ化に基づいて集計されたテナントの日次販売を一覧表示または選択することができました。

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 

そして結果はこの

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

ようなものです私は最終的な出力は、として最初の行と月のように日の日付を持つ表形式で結果を作るあるとして達成したいです列。 詳しい説明はサンプル出力をご覧ください。

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 

これは私がピボットを使用することが示唆されているが、それは私に非常に新しいものであるとする方法がある場合は、非常に複雑なように見えた

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) 

を試みたものですはるかに良いTSQLだけを使用してください。

-- 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]
