SQL Server 2012分組依據

Question

我想要此查詢的結果，以從發布了大多數文章的標簽表中獲取前10個值

select distinct top 10  Name as 'Tag Name' 
from Articles join Tags on Articles.TagID=Tags.ID 
group by Tags.Name 
order by count(Articles.TagID) 

但它給出了以下錯誤

Msg 145, Level 15, State 1, Line 1
ORDER BY items must appear in the select list if SELECT DISTINCT is specified.

Answer 1

如果按該列分組，則不需要distinct 。

select top 10 
       Name as 'Tag Name' 
from Articles 
join Tags on Articles.TagID = Tags.ID 
group by Tags.Name 
order by count(Articles.TagID) desc
