【问题描述】：

在我的销售表中，列出的是某一物业中特定租户的每日销售额。

使用此代码，我能够列出或选择租户的每日销售额，根据物业分组进行汇总。

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

结果是这样的

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

作为最终输出，我希望完成的是以表格形式生成结果，其中将 Days 日期作为第一行，将 Month 作为列。 请查看示例输出以获得进一步说明。

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     .      .    .        .       .    .

这是我尝试过的

 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)

有人建议我使用pivot，但这对我来说很新，而且似乎很复杂，如果有办法只使用TSQL，那就更好了。

希望得到您的专家建议。

谢谢！

-- 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]
