Question

我的表结构如下：

Name   email          score time
Hello  abc@gmail.com  100   15
Hello  abc@gmail.com  58    10
Test   def@gmail.com  100   12 
Stack  xyz@gmail.com  90    20
Test   def@gmail.com  50    40

使用选择查询

$q="SELECT name, MAX(score) as score ,email FROM users GROUP BY email ORDER BY MAX(score) DESC LIMIT 10";

生成结果。

Name   email          score time
Hello  abc@gmail.com  100   15
Test   def@gmail.com  100   12 
Stack  xyz@gmail.com  90    20

我感到困惑的是，如果两个用户得分相同，我想根据最短的时间对结果进行排序，因为“测试”用户在12秒内得分为100，所以应该先得分。

Answer 1

SELECT name, MAX(score) as score, email 
FROM users GROUP BY email 
ORDER BY MAX(score) DESC, time ASC LIMIT 10; # note how multiple column ordering is made

了解详情：SQL multiple column ordering

Answer 2

试试这个mysql查询

  $q="SELECT name, MAX(score) as score 
       ,email FROM users GROUP BY email 
      ORDER BY MAX(score) DESC,time LIMIT 10 ";

按分数排序然后按时间排序
