[英]Insert and update same table with transactions
Since I can't/don't know how to auto_increment two columns in one table I trying to do this with transactions. 由于我无法/不知道如何在一个表中自动递增两列,因此尝试使用事务来做到这一点。 This is what I trying
这就是我的尝试
$pdo->beginTransaction();
try
{
$sql = "INSERT INTO users ( username, password, firstname, lastname, email, user_image, path)
VALUES (:username, :password, :firstname, :lastname, :email, :user_image, :path)";
$q = $pdo->prepare($sql);
$q->execute(array(
':username' => $username,
':password' => sha1($password),
':firstname' => $firstname,
':lastname' => $lastname,
':email' => $email,
':user_image' => $forDB,
':path' => $path,
));
$lastInsertID = $pdo->lastInsertId();
$sql = $pdo->prepare("INSERT INTO users (usertype)
VALUE (:user_id)");
$sql->execute(array(
':user_id' => $lastInsertID
));
$pdo->commit();
}
// any errors from the above database queries will be catched
catch (PDOException $e)
{
// roll back transaction
$pdo->rollback();
// log any errors to file
ExceptionErrorHandler($e);
exit;
}
So basically I want to insert in column usertype
the ID of this record (user_id) both columns must be equal. 所以基本上我想在列中插入
usertype
此记录(USER_ID)的ID两列必须相等。 Now when I try with this .. it is save empty fields except for the usertype
which is updated with lastInsertID
现在,当我尝试使用此..时,将保存空字段,但使用
usertype
更新的用户lastInsertID
Change 更改
$sql = $pdo->prepare("INSERT INTO users (usertype)
VALUE (:user_id)");
to this 对此
$sql = $pdo->prepare("UPDATE users SET usertype=:user_id WHERE user_id=:user_id");
