我正在尝试将 mysql 函数 FROM_UNIXTIME 与 PDO 一起使用：

$sth = $dbh->prepare("UPDATE ".DB_PREFIX."_logins SET num_of_trys = num_trys-1, 
       last_try = FROM_UNIXTIME(:last_try), WHERE username = :username 
       OR ip = :ip");
$sth->bindParam(':ip', $ip); 
$sth->bindParam(':username', $user);
$sth->bindParam(':last_try', $lst);
$sth->execute();

但我收到错误消息。这样做的正确方法是什么？

这是错误消息：

Fatal error: 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
