select top 10 a.id,title,adddate,num from ks_article a,(select infoid,count(*) as num from ks_comment where channelid=1 group by infoid)b where a.id=b.infoid order by b.num desc

这里查询的是文章系统,要查其他系统改下就可以了,试试看行不行

循环体：

[loop=10]

<li><a href="{$Field(id,GetInfoUrl,1,1)}">{$Field(title,Text,0,...,0,)}</a>({$Field(num,Num,0,2)})</li>

[/loop]
