还是问一个mysql的查询汇总的汇总问题

本帖最后由 setoy 于 2013-12-18 18:11:02 编辑 有五个人,uid分别是1~5
有对着这五个人打分的表格(某个人有可能没有得到过分数)
id  uid  scroe<br />
-------------<br />
1    1    1.5<br />
2    1    1.8<br />
3    2    -5.5<br />
4    1    0.8<br />
5    2    8.2<br />
6    1    -2<br />
7    4    3<br />
8    2    2.3<br />
--------------


现在要统计他们所有人的分数,即使查询不到某个人的得分,也要显示0分,显示格式如下:
用户  分数   汇总分<br />
-----------------------<br />
1      1.5     2.1<br />
1      1.8     2.1<br />
1      0.8     2.1<br />
1      -2      2.1<br />
2      -5.5    5<br />
2      8.2     5<br />
2      2.3     5<br />
3      0       0<br />
4      3       3<br />
5      0       0<br />
