PDO選擇從2個表

Question

加入

所以我有工作的查詢，但我想添加一個功能是用戶可以「暫停」

$stmt212 = $db->prepare('SELECT * 
FROM websites w 
    LEFT JOIN users u ON u.username = w.owner 
WHERE u.coins >= ? 
ORDER BY RAND() 
LIMIT 1'); 
$stmt212->execute(array('1')) ; 
$row212 = $stmt212->fetch(); 

這工作，但現在我需要從網站選擇了直播= 1有好有超過1硬幣在user表中也嘗試這種

$stmt212 = $db->prepare('SELECT * 
FROM websites WHERE live = ? 
    LEFT JOIN users u ON u.username = w.owner 
WHERE u.coins >= ? 
ORDER BY RAND() 
LIMIT 1'); 
$stmt212->execute(array('1','1')) ; 
$row212 = $stmt212->fetch(); 

但沒有工作

Answer 1

試試這個：

$stmt212 = $db->prepare('SELECT * 
FROM websites 
LEFT JOIN users u ON u.username = w.owner 
WHERE u.coins >= ? 
AND live = ? 
ORDER BY RAND() 
LIMIT 1'); 

$stmt212->execute(array('1','1')) ; 
$row212 = $stmt212->fetch();
