mysql - PHP数据排序问题？

我正在做一个学生成绩排名的功能，导入原生成绩数据（语文、数学、英语、物理、化学、生物、历史、地理、政治）然后计算出每位同学的各科班级排名和各科年级排名情况，后期支持导出数据（原生成绩+成绩单科班级排名+成绩单科年级排名）。

举例

考号	年级	班级	语文	语文班名次	语文级名次
1	1	1	70
2	1	2	80
3	1	2	90
4	1	1	70
5	1	2	80
6	1	3	81
7	1	1	70
8	1	2	80
9	1	3	90
10	1	1	70
11	1	2	80
12	1	2	90
13	1	1	70
14	1	3	81
15	1	2	90

1. 排名是在导入数据时php处理，还是导入原始数据后再用mysql处理，给一个示例一下，谢谢

2. 相同分数名次相同如何处理

补充一个php做的分数排序，如何和排名序号结合起来？同分一样如何处理呢？（为了自己认识全是中文键名）

回复内容：

我正在做一个学生成绩排名的功能，导入原生成绩数据（语文、数学、英语、物理、化学、生物、历史、地理、政治）然后计算出每位同学的各科班级排名和各科年级排名情况，后期支持导出数据（原生成绩+成绩单科班级排名+成绩单科年级排名）。

举例

考号	年级	班级	语文	语文班名次	语文级名次
1	1	1	70
2	1	2	80
3	1	2	90
4	1	1	70
5	1	2	80
6	1	3	81
7	1	1	70
8	1	2	80
9	1	3	90
10	1	1	70
11	1	2	80
12	1	2	90
13	1	1	70
14	1	3	81
15	1	2	90

1. 排名是在导入数据时php处理，还是导入原始数据后再用mysql处理，给一个示例一下，谢谢

2. 相同分数名次相同如何处理

补充一个php做的分数排序，如何和排名序号结合起来？同分一样如何处理呢？（为了自己认识全是中文键名）

1. 导入到数据库，然后用mysql处理
   2.同分的帅的往前

建议是存到数据库,然后取出来的时候再计算名次,否则数据库中写死了,以后再在增删改数据的时候,名次还要重新计算.

数据库语句:

<code>SELECT * FROM `成绩表` order by 分数,名次 ASC ,学号 DESC;
分数由小到大,当分数相同
名次有小到大,当名次相同
学号由大到小</code>

同理可以通过数据库读出数据进行排名从而进行排名再存入数据库

php:
如果名次不存在,可以读取数据库,在php中计算名次

1- 导入之后再update
update table as t1 set 班名次 = (select count() from table as t2 where t1.班级 = t2.班级 and t1.年级 = t2.年级 and t1.成绩 ) from table as t3 where t1.年级 = t3.年级 and t1.成绩

2- 并列啊
