<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");

$session->sql("CREATE DATABASE foo")->execute();
$session->sql("CREATE TABLE foo.test_table(x int)")->execute();

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

Array
(
    [0] => mysql_xdevapi\Warning Object
        (
            [message] => Division by 0
            [level] => 2
            [code] => 1365
        )
    [1] => mysql_xdevapi\Warning Object
        (
            [message] => Division by 0
            [level] => 2
            [code] => 1365
        )
