與綁定PHP PDO UPDATE查詢參數

Question

我試圖運行下面的查詢：

$sth = "UPDATE `users` SET users_password VALUES (:hash) WHERE users_id = $users_id"; 
$q = $conn->prepare($sth); 
$q->execute(array(':hash'=>$hash)); 

但即時得到以下幾點：

Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VALUES ('$2y$12$Ao46iC7W9Lj8FFfSmAaeoeQs9O.3QRVtDbHAyvpzH90YIUN61ma8i') WHERE us' at line 1' 

任何想法？

（是的代碼是不是在一個try，catch塊還只是在試驗他們的幾件事情時刻）

Answer 1

改變這種

$sth = "UPDATE `users` SET users_password VALUES (:hash) WHERE users_id = $users_id"; 

到

$sth = "UPDATE `users` SET users_password = :hash WHERE users_id = $users_id";
