PDO，fetchall和multiquery

Question

好吧，我正在做的事情是不可能的，我這樣做的方式（我已經連續兩天......再次），但它是可能的運行通過PDO進行多重查詢並返回所有結果...就像這樣？

$sql = 
"SELECT username, faction FROM users WHERE uid = :uid;". 
"SELECT level, exp, health, luck, first_name, last_name FROM player_information WHERE uid = :uid"; 
    $que = $this->db->prepare($sql); 
    $que->bindParam('uid', $uid); 
    try{ 
     $que->execute(); 
     $row = $que->fetchAll(); 
     print_r($row); 
    }catch(PDOException $e){$e->getMessage(); } 

還是我只是吠叫錯了樹？

Answer 1

你應該在交易一看：http://www.php.net/manual/en/pdo.transactions.php

Answer 2

是，這樣的 「multiquery」 被稱爲JOIN：

SELECT username, faction, level, exp, health, luck, first_name, last_name 
FROM users u, player_information pi WHERE u.uid = pi.uid AND u.uid = :uid 

也，你在呼喚它

在使用錯誤的運營商

$sql = "SELECT username, faction, level, exp, health, luck, first_name, last_name 
     FROM users u, player_information pi WHERE u.uid = pi.uid AND u.uid = ?"; 
$stm = $this->db->prepare($sql); 
$stm->execute(array($uid)); 
$row = $que->fetch(); 
print_r($row); 

會以較少的代碼給你結果
