问题描述
我在使用 PDO 更新数据库时遇到错误.我是 PDO 的新手，所以问题可能很小，我只是不明白.这个错误很有趣，命令运行良好，数据库确实得到了更新.但它仍然向我返回一个错误.
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]:一般错误
Error: ERROR UPDATING CONTENT: SQLSTATE[HY000]: General error
我真的不知道问题出在哪里，因为它非常空洞，而且我找不到任何有同样问题的人.
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
你不使用 fetchAll()，如
You do not use fetchAll(),as in
$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.
