PDO 如何回显更新了多少
PDO How to echo how many updated
如何回显使用此代码更新了多少条记录?
我知道我可以在公共更新中做到这一点:
echo $stmt->rowCount() . " records UPDATED successfully";
但是这里的问题是,同时有多个更新的时候怎么办
关于可能重复的注意事项:我已经解释过我的问题不同于:PDO were rows affected during execute statement
该解决方案适用于单个更新,在此代码中不起作用。我问的是多次更新时如何统计
try {
require_once 'connexion.php';
$stmt = $conn->prepare("UPDATE bookmarks
SET podcast=:podcast, text=:text
WHERE id=:id");
$stmt->bindParam(':podcast', $podcast);
$stmt->bindParam(':text', $text);
$stmt->bindParam(':id', $id);
$podcast = 1;
$text = "text 1";
$id = 147;
$stmt->execute();
// another row:
$podcast = 2;
$text = "text 2";
$id = 265;
$stmt->execute();
// echo " records UPDATED successfully";
}
catch(PDOException $e){
echo $e->getMessage();
}
尝试$stm->rowCount()

这里也有人问过这个问题:
试试这个。
当你做多个 ->execute()
时,你必须在你做的时候捕获每个 ->execute()
的计数,然后在最后显示累积的总计数
try {
require_once 'connexion.php';
$update_count = 0;
$stmt = $conn->prepare("UPDATE bookmarks
SET podcast=:podcast, text=:text
WHERE id=:id");
$stmt->bindParam(':podcast', $podcast);
$stmt->bindParam(':text', $text);
$stmt->bindParam(':id', $id);
$podcast = 1;
$text = "text 1";
$id = 147;
$stmt->execute();
$update_count += $stmt->rowCount();
// another row:
$podcast = 2;
$text = "text 2";
$id = 265;
$stmt->execute();
$update_count += $stmt->rowCount();
echo "$update_count records UPDATED successfully";
}
catch(PDOException $e){
echo $e->getMessage();
}
