Question

我的查询如下：

 SELECT  top  8  (OrderTH_strMovieName) as Top8HotFilms,
  Convert(char(8), OrderTH_dtmSessionDateTime, 112) as DayOfCount,
  count( OrderTH_strMovieName)as filmoccurence 
  FROM [MOVIES].[dbo].[tblOrderTicketHistory]
  where Convert(char(8), OrderTH_dtmSessionDateTime, 112) >= 
                (SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))) 
  GROuP  BY OrderTH_strMovieName , 
           Convert(char(8), OrderTH_dtmSessionDateTime, 112) 
  ORDER BY filmoccurence desc

结果如下：

Movies           Session Day    Occurence .tix
*SAN ANDREAS        20150531    2156
*MASSS              20150531    1954
*TOMORROWLAND       20150531    990
SPY                 20150531    825
PITCH PERFECT 2     20150531    374
MAD MAX FURY ROAD   20150531    302
*MASSS              20150601    268
*SAN ANDREAS        20150601    257

现在问一下，如何导出一个名为number的列，最终结果如下？

Number Movies            Session Day    Occurence .tix
   1  *SAN ANDREAS          20150531    2156
   2  *MASSS                20150531    1954
   3  *TOMORROWLAND         20150531    990
   4  SPY                   20150531    825
   5  PITCH PERFECT 2       20150531    374
   6  MAD MAX FURY ROAD     20150531    302
   7  *MASSS                20150601    268
   8  *SAN ANDREAS          20150601    257

Answer 1

你可以尝试下面的

SELECT  top  8 RANK() 
            OVER (ORDER BY count( OrderTH_strMovieName) desc) AS Number, 
      (OrderTH_strMovieName) as Top8HotFilms,
      Convert(char(8), OrderTH_dtmSessionDateTime, 112) as DayOfCount,
      count( OrderTH_strMovieName)as filmoccurence 
      FROM [MOVIES].[dbo].[tblOrderTicketHistory]
      where Convert(char(8), OrderTH_dtmSessionDateTime, 112) >= 
                    (SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))) 
      GROuP  BY OrderTH_strMovieName , 
               Convert(char(8), OrderTH_dtmSessionDateTime, 112)

例如：

    create table test
(name varchar(10),
 age numeric)

 insert into test values ('John',10);
 insert into test values('Happy',20);
 insert into test values ('mary',35);
  insert into test values ('mary',35);
 insert into test values ('John',10);

SELECT  top  2 ROW_NUMBER() over(ORDER BY sum(age)) as number,
     name as n,
     sum(age) as age_sum

来自测试按名称分组按名称排序

   number   n   age_sum
   1     Happy   20
  2      John   20

在您的查询中选择ROW NUMBER：https://msdn.microsoft.com/en-us/library/ms186734.aspx

Answer 3

  select top 8 RANK() OVER(ORDER BY moviesHit.filmoccurence ASC) as Rank,
  moviesHit.Top8HotFilms,moviesHit.filmoccurence
  from 
  (
   SELECT (OrderTH_strMovieName) as Top8HotFilms,

   count( OrderTH_strMovieName)as filmoccurence 
   FROM [MOVIES].[dbo].[tblOrderTicketHistory] 
   where Convert(char(8), OrderTH_dtmSessionDateTime, 112) >= 
     (SELECT     DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))) 
   GROuP  BY OrderTH_strMovieName  
   ) as moviesHit    order by moviesHit.filmoccurence ASC
