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);
?>

以上例程的输出类似于：

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
        )
)
