MySQL ERROR when adding column

Website Building
#1

iam using MySQL and phpMyAdmin at www.000webhost.com. My problem is: when I add a new column in the database (7 to 8) I get these errors:

Warning: mysqli_stmt::execute(): Premature end of data (mysqlnd_wireprotocol.c:1130) in /storage/ssd3/216/2786216/public_html/pages/login.php on line 13

Warning: mysqli_stmt::execute(): RSET_HEADER packet 4 bytes shorter than expected in /storage/ssd3/216/2786216/public_html/pages/login.php on line 13

Warning: mysqli_stmt::execute(): Error reading result set’s header in /storage/ssd3/216/2786216/public_html/pages/login.php on line 13

Notice: Trying to get property of non-object in /storage/ssd3/216/2786216/public_html/pages/login.php on line 16
Does somebody know how to fix it?

#2

Why not add it within the phpmyadmin area?

#3

I do add the column in phpMyAdmin.

Hi @RealNiclas!

Please lower your PHP version and try again: 000webhost cPanel > Settings > General > Change PHP version > 5.6

#5

No changes :confused:

This usually means there are incompatibilities between PHP query DB versions and MySQL database system. We are using MariaDB which is a little different from the traditional MySQL.

Please keep changing your PHP version and keep trying.

#7

To add a column use this
ALTER TABLE table_name ADD COLUMN column_name VARCHAR(1000

#8

With PHP version 7.0 it works, but now I get this error:

Warning: mysqli_stmt::execute(): Premature end of data (mysqlnd_wireprotocol.c:1114) in /storage/ssd3/216/2786216/public_html/pages/admininterface.php on line 68

Line 65-70:
require("…/dbconnect.php");
$search_user = $db->prepare(“SELECT * FROM users WHERE id=?”);
$search_user->bind_param(“i”,$_SESSION[“user”]);
$search_user->execute();
$search_result = $search_user->get_result();
$search_object = $search_result->fetch_object();

Comment out $search_user -> get_result() and check again.

#10

Any known fix to this issue? After adding a 5th column (boolean) this has started happening.

Warning: mysqli_stmt::execute(): Premature end of data (mysqlnd_wireprotocol.c:1130) in /storage/ssd1/421/4460421/public_html/account/index.php on line 22

Lines 20-24:

$stmt = $conn->prepare('SELECT * FROM account_information WHERE account = ?');
$stmt->bind_param('s', $account);
$stmt->execute();
$result = $stmt->get_result();
if ($result->num_rows > 0) {

By the way, what I’ve done (add a new column with the exact same code) works completely fine on a local server (XAMPP).

Maybe try changing your PhP version? :slight_smile:

#12

I’ve tried what’s been suggested so far.
