How can i use SQL queries to get following Output.

我只想先按角色 ID 3 排序，然后再按剩余的角色 ID 排序.目前我正在使用 Union 来实现//

I just want to Order by Role Id 3 first then by remaining Roleid. Currently i am using Union to achieve so //

SELECT * FROM (SELECT * From @temp 
         Where roleid=3
UNION ALL
SELECT * From @temp 
         Where roleid != 3
 ) as X 

推荐答案

您可以使用 case 进行更复杂的排序:

You can use case to make more complex ordering:

select *
 from @temp
 order by case when Role = 3 then 0 else 1 end, Role, Name
