mysql - 使用MySQL查询的十大计数

我使用以下mysql查询对refererSource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，我想按结果集的升序排序。如何更改上面的查询。请给出建议

最佳答案

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