使用 PHP 获取 MySQL 表中用户的总积分

Question

I have a MySQL table with the columns "user" and "warningpoints" for each warning as you can see in the table above. How can I get the user which has the most warningpoints in total in PHP?

Answer 1

You can use GROUP BY and ORDER BY and LIMIT :

SELECT t.user,sum(t.warningPoints) as sum_points
FROM YourTable t
GROUP BY t.user
ORDER BY sum_points DESC
LIMIT 1;

Or if there is only one record per person, no need to group :

SELECT t.user,t.warningPoints 
FROM YourTable t
ORDER BY t.warningPoints DESC
LIMIT 1;

Answer 2

You can simply add below statements in your php code.

$sql = "SELECT User, Max(warningpoints) AS MaxWarningpoints FROM MyGuests GROUP BY User";
$result = $conn->query($sql);
