遇到問題在MySQL

Question

使用我司希望得到普及制訂總的意見/圖片數量： 這是代碼：

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

我得到這個錯誤： 語法錯誤或訪問衝突： 1064你的SQL語法有錯誤;檢查對應於你的MySQL服務器版本使用附近的「COUNT（p.views）/ SUM（p.id）爲普及正確的語法手冊

Answer 1

你失蹤後一個逗號：

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");
