    Example #1 mysql_xdevapi\RowResult::getWarnings() example

    <?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();

    $schema = $session->getSchema("foo");
    $table = $schema->getTable("test_table");

    $table->insert(['x'])->values([1])->values([2])->execute();

    $res = $table->select(['x/0 as bad_x'])->execute();
    $warnings = $res->getWarnings();

    print_r($warnings);
    ?>

    The above example will output something similar to:

    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 ) )
