Question

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

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

我需要为每个玩家遍历表格，计算总积分并输出排行榜风格

最佳数据库结果

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GROUP BY并按SUM列命令desc。

也许您需要一些过滤器位置

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

循环MySQL并使用PHP添加点
