create tableuser (name varchar(20),并加入_time int(11)
这里,我的问题是:当把记录放在一起——当时的裁军和安全局命令中的时候,我如何能够获得每个记录的排名?
事先感谢你。
Try:
select @rownum:=@rownum+1 `rank`, u.*
from (select * from `user` order by join_time desc) u,
(SELECT @rownum:=0) r
您需要的是row_ number(s) over (order by some), 它将根据规定的命令条款退回到行数,但我不清楚的是,在我的sql中是否能够提供。
某些搜索发现,我的sql没有行号——编号功能,但有许多工作要做,以命名一个。 http://craftycodeblog.com/201009/13/rownum-simulation-with-mysql/
