获得前5个帖子计数sql

Question

我正在尝试根据他们的帖子计数获得我数据库中的前5位用户

<?php
$data = mysql_query("SELECT COUNT(*) FROM pins ORDER BY user_id ASC LIMIT 5")
    or die(mysql_error()); 
while($info = mysql_fetch_array( $data )) 
{ 
    Print "<table><tr><td>";
    Print "".$info['user_id']."";
    Print "</td></tr></table>";
} 
?>

这是我改编的代码,适用于具有WHERE user_id='999'子句的个人用户.但是如何更改它以获得前5名呢？

Answer 1

用途GROUP BY:

SELECT user_id
FROM pins
GROUP BY user_id
ORDER BY COUNT(*) DESC
LIMIT 5
