如何显示平均分数？

Question

我用PHP和MySQL保存游戏的分数，表格看起来像这样。

ID USERID SCORE
1  23     200
2  45     145
3  64     231

等...

现在PHP或MySQL代码可以让我显示平均分数？ 感谢。

Answer 1

用户的平均分数？这应该这样做：

SELECT USERID, AVG(SCORE) AS AVERAGE_SCORE
FROM
    TABLE_NAME
GROUP BY
    USERID

对于整个表格：

SELECT AVG(SCORE) AS AVERAGE_SCORE
FROM
    TABLE_NAME

SELECT AVG(`SCORE`) as AVG_SCORE FROM `YOURTABLE`

SELECT AVG(score) AS average_score FROM 'table'
