使用Mysql查询排名前十

我使用以下mysql查询对referrersource进行分组

SELECT referrersource,count(referrersource) as counts 
FROM request_events  
where referrersource!='' 
AND landingpage_collectionid=1 
group by referrersource

在这里，我想按我的结果集按升序排序。如何更改我的上述查询。如有任何建议，请添加一个子句

---

添加

按计数排序DESC

？

只需添加

按计数排序子句，例如

 SELECT referrersource,count(referrersource) as counts 
 FROM request_events  
 where referrersource!='' 
 AND landingpage_collectionid=1 
 group by referrersource
 ORDER BY 2

ORDER BY count(referrersource)

ORDER BY count(referrersource)
