Mysql如何对成绩进行排名并记录？

今天查询时需要用到降序排列，老是出错，仔细检查SQL语法也没问题，

后来才知道，原来order by要放在limit的前面。或者说limit要放在最后。

[sql]

String sql = "select * from s_dayreport " +

"where userId = "+userId+" " +

"order by taskDate desc " +

"limit "+firstResult+","+maxResults+" "降序排列的例子，插入的数据无关，关键是你打印出或者展现出的效果

select t.yuwen, t.shuxue, t.waiyu, (t.yuwen+ t.shuxue+ t.waiyu) fsum

from stu t

order by fsum desc
