如何根据条件对多列进行排序

declare @result table (FirstFieldID int, FirstFieldIDName varchar(100), SecondFieldID int, SecondFieldName varchar(100),ObjectID int, ObjectName varchar(100), SubSort int ,TotalStudents int) 
insert into @result

目前我的数据如上所述。当ObjectID和ObjectName为-1时，TotalStudents将按组中的降序排列。否则，ObjectName是升序。期待下面的数据。如何根据条件对多列进行排序

https://ozh.github.io/ascii-tables/使ASCII表从你的投入将是asier阅读。 – xQbert

['ORDER BY']（https://docs.microsoft.com/zh-cn/sql/t-sql/queries/select-order-by-clause-transact-sql）和['CASE']（https ：//docs.microsoft.com/en-us/sql/t-sql/language-elements/case-transact-sql）应该这样做。对这些术语（和SQL）的搜索将提供大量结果。 – HABO

尝试了很多方法，请求发布查询 –

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

您正在寻找这样的事情？

谢谢。但预期产量不同。 –

根据[数据类型优先顺序]（https://docs.microsoft.com/zh-cn/sql/t-sql/data-types/data-type-precedence-transact-sql），“ObjectName”将为转换为“INT”进行比较。对于像“11年级”这样的价值观来说，这不太可能。 – HABO

@HABO，我尝试了下面的内容，我可以得到50％的正确率。从FirstResultID = -1和ObjectID = -1和SecondFieldID = -1开始按#ResultTable排序，然后TotalStudents结束desc，当FirstFieldID！= -1和ObjectID = -1且SecondFieldID！= -1时，则TotalStudents结束desc，当FirstFieldID！= -1和ObjectID！= -1时，则SecondFieldID结束asc 它不符合我的要求。 –

我认为你正在寻找查询象下面这样：

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

仍不能确定你由内而外组是什么意思？团队如何进行排序？

如果ObjectID = -1且ObjectName = -1，则它是与FirstFieldIDName和SecondFieldName相关的基础ObjectName的标头。 –

在哪个序列中？ –

如果ObjectID = -1且ObjectName = -1，那么** TotalStudents **将降序并且ObjectID！= - 1和ObjectName！= -1为相应的FirstFieldIDName和SecondFieldName，然后** TotalStudents **将升序 –

尝试下面，让我知道，如果它的工作原理：

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'

此处的排序仅基于studentid完成。您需要根据您的要求在row_number（）子句中找出分组和排序 – Aparna

谢谢。但我上面发布的预期结果是不同的。我期待与我发布的结果相同。 –
