遇到问题在MySQL

Question

使用我司希望得到普及制订总的意见/图片数量： 这是代码：

$users = DB::query("SELECT * , 
    COUNT(p.id) as numPics, 
    SUM(p.views) as totalViews 
    COUNT(p.views)/SUM(p.id) as popularity 
FROM 
    images p 
INNER JOIN 
    users u 
ON 
    p.user_id = u.id 
WHERE 
p.created_at >= \"$current_month\" 
GROUP BY p.user_id 
ORDER BY popularity DESC LIMIT 10"); 

我得到这个错误： 语法错误或访问冲突： 1064你的SQL语法有错误;检查对应于你的MySQL服务器版本使用附近的“COUNT（p.views）/ SUM（p.id）为普及正确的语法手册

Answer 1

你失踪后一个逗号：

SUM(p.views) as totalViews 

Answer 2

$users = DB::query("SELECT * , 
    COUNT(p.id) as numPics, 
    SUM(p.views) as totalViews , 
    COUNT(p.views)/SUM(p.id) as popularity 
FROM 
    images p 
INNER JOIN 
    users u 
ON 
    p.user_id = u.id 
WHERE 
p.created_at >= '$current_month' 
GROUP BY p.user_id 
ORDER BY popularity DESC LIMIT 10");
