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

= 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");


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

    [1] => mysql_xdevapi\Warning Object
            [message] => Division by 0
