php - 循环MySQL并使用PHP添加点

Question

我正在为我们的社交飞镖俱乐部创建一个排行榜系统。我有一个 MySQL 数据库，其中包含玩家姓名及其得分

示例:

Name      Date            Place        Points
John      11-01-2015      1st          10
Anthony   12-01-2015      1st          10
Andre     13-01-2015      1st          10
John      14-01-2015      1st          10

我需要循环遍历每个玩家的表格，计算总分并输出排行榜样式

顶级数据库结果

Name                          Points
John                          20
Andre                         10
Anthony                       10

Answer 1

SELECT name, SUM(points) AS points
  FROM table1
GROUP BY name
ORDER BY 2 DESC;

构建一个 GROUP BY 并按 SUM 列对 desc 进行排序。

也许你需要一些过滤的地方

SELECT name, SUM(points) AS points
  FROM table1
WHERE place = '1st'
GROUP BY name
ORDER BY 2 DESC;
