Question

I am saving the scores of a game with PHP and MySQL, the table looks like this.

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

etc…

Now what PHP or MySQL code can let me show the average scores ?
Thanks.

Answer 1

A user’s average score? This should do it:

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

For the entire table:

SELECT AVG(SCORE) AS AVERAGE_SCORE
FROM
    TABLE_NAME
