PDO错误:"SQLSTATE [HY000]:一般错误"更新数据库时

问题描述

使用PDO更新数据库时出现错误.我是PDO的新手，所以问题可能很小，我只是不明白.关于错误的有趣的事情，该命令可以正常工作，并且数据库确实得到了更新.但是它仍然向我返回错误.

I am getting an error when updating a database using PDO.I am new to PDO so maybe the problem is a small one and I just don't understand.Funny thing about the error, the command works fine and the database does actually get updated.But it still returns an error back at me.

代码:

try {
    $stmt = $pdo->prepare("UPDATE $page SET $section = :new_content WHERE $section = '$old_content'");
    $stmt->execute(array(
        'new_content' => $new_content
    ));
    $result = $stmt->fetchAll();
    echo "Database updated!";
}
catch(PDOException $e) {
    echo 'ERROR UPDATING CONTENT: ' . $e->getMessage();
}

错误:错误更新内容:SQLSTATE [HY000]:常规错误

Error:ERROR UPDATING CONTENT: SQLSTATE[HY000]: General error

我真的不知道问题出在哪里，因为它非常怪诞，而且我找不到任何遇到相同问题的人.

I literally have no idea where the problem could be because its very vaque and I haven't been able to find anyone with the same problem.

推荐答案

您不像在

$result = $stmt->fetchAll();

带有更新或插入查询.删除此语句应该可以解决问题.

with update or insert queries. Removing this statement should rectify the problem.
