rawQuery not throwing an Exception on a Transaction

[GuiTessari]

Hello,

I'm using rawQuery() with transaction and after some tests I realized that even if one insert fails the commit will happen.
This is a simple example:

CREATE TABLE test (
id int(8)
);

try{
$this->mysqlidb->startTransaction();

    $this->mysqlidb->insert("test", Array("id" => 1));
    //$this->mysqlidb->insert("test", Array("id" => 1, "test" => 2)); -> Throwing an Exception
    //$sql = "insert into test(id, test) values (1, 2)"; -> Throwing an Exception
    $sql1 = "insert into test (select 1, 2 from dual)"; -> Not throwing an Exception
    $this->mysqlidb->rawQuery($sql1);

    $this->mysqlidb->commit();

    print_r($this->mysqlidb->get("test", null, "id"));

} catch (Exception $e) {
echo $e->getMessage();
}

So, after execute this it will insert the id 1 even though the second insert returns an error.
It probably will be fixed by adding some verification after $stmt->execute(); in the rawQuery function.
