MS-SQL 按降序排序输出

2022-01-09 00:00:00 sql-server coldfusion

我有这个 MS-SQL 查询，数据库中有数千行记录:

I have this MS-SQL query with thousands of row records in database:

SELECT DISTINCT TOP 7 DATENAME(MM, mydatetime) + ' ' + CAST(DAY(mydatetime) AS VARCHAR(2)) as thedate
    , MONTH(mydatetime)
    , DAY(mydatetime)
    , COUNT(Page) as totalcount
    , count(DISTINCT Page) as visitors
  FROM someTable
  WHERE Page LIKE '%AEC%'
  GROUP BY DATENAME(MM, mydatetime) + ' ' + CAST(DAY(mydatetime) AS VARCHAR(2))
    , MONTH(mydatetime)
    , DAY(mydatetime)
  ORDER BY MONTH(mydatetime) DESC
    , DAY(mydatetime) DESC

它会输出这个:

It will output this:

thedate     | totalcount | visitors
-----------------------------------
October 17  |     4      |    1
October 15  |     1      |    1
October 12  |     1      |    1
October 3   |     3      |    3
October 2   |     42     |    22
September 28|     2      |    1
September 21|     14     |    10

我的问题是我根本无法按降序输出，所以它看起来像这样:

My problem is that I simply cant output this in descending order so it will look like this:

thedate     | totalcount | visitors
-----------------------------------
September 21|     14     |    10
September 28|     2      |    1
October 2   |     42     |    22
October 3   |     3      |    3
October 12  |     1      |    1
October 15  |     1      |    1
October 17  |     4      |    1

非常感谢任何帮助.

推荐答案

对于您的实际需求，您可以将当前查询用作派生表并按照您想要的方式排序:

For your actual requirement, you can use your current query as a derived table and order that result in the way you want:

SELECT *
FROM (  SELECT DISTINCT TOP 7 DATENAME(mm, mydatetime) + ' ' 
                              + CAST(DAY(mydatetime) AS VARCHAR(2)) AS thedate, 
                              MONTH(mydatetime)                     AS theMonth, 
                              DAY(mydatetime)                       AS theDay, 
                              COUNT(page)                           AS totalcount, 
                              COUNT(DISTINCT page)                  AS visitors 
        FROM   sometable 
        WHERE  page LIKE '%AEC%' 
        GROUP  BY DATENAME(mm, mydatetime) + ' ' 
                  + CAST(DAY(mydatetime) AS VARCHAR(2)), 
                  MONTH(mydatetime), 
                  DAY(mydatetime) 
        ORDER  BY MONTH(mydatetime) DESC, 
                  DAY(mydatetime) DESC) A
ORDER BY theMonth, theDay
