目前我的数据如上所述。当ObjectID和ObjectName为-1时， TotalStudents 将在组中按降序排列。否则ObjectName是升序。期待下面的数据。

谢谢。

Answer 1

CASE WHEN statement for ORDER BY clause

SELECT *
FROM TABLE
ORDER BY
CASE WHEN ObjectID = -1 AND ObjectName = -1 THEN TotalStudents END DESC
CASE WHEN ObjectID <> -1 AND ObjectName <> -1 THEN ObjectName END ASC

你在找这样的东西吗？

Answer 2

我认为您正在寻找如下查询：

Select * from #sortData
order by case when objectid =-1 and objectname = '-1' then row_number() over(order by TotalStudents) 
        when objectid <> -1 then row_number() over(order by ObjectName asc) end desc

仍然不确定你的内心组是什么意思？如何对组进行排序？

Answer 3

尝试下面的内容，让我知道它是否有效：

select * ,row_number() over(partition by flag order by totalstudents desc) 
as rn from(   
          select *, 
          case when objectid=-1 and objectname='-1' then  'Des' else 'Asc' 
          end as flag  
          from result
        )a
   where flag='Des'
   union all
  select * ,row_number() over(partition by flag order by totalstudents) as 
  rn1 from(   
           select *, 
           case when objectid=-1 and objectname='-1' then  'Des' else 'Asc' 
           end as flag  
           from result
         )a
     where flag='Asc'

如何根据条件对多列进行排序
