十大计数使用Mysql Query

Question

我正在使用以下mysql查询来分组referrersource。

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

在这里，我想按结果集按升序排序。如何更改我的上述查询。请提供任何建议

Answer 1

添加ORDER BY counts DESC？

Answer 2

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

Answer 3

添加ORDER BY子句。

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

Answer 4

只需添加ORDER BY子句，例如

ORDER BY count(referrersource)
