$data['results'] = $this->testquery->query1();
$this->load->view("view_db");

$query = $this->db->query($sql);
foreach ($query->result() as $row)
{
echo $row->color_id;
echo $row->color_name;
echo $row->color_desc;
}
*/
return $query->result();

Am i missing something? 我想念什么吗？ I have gone through other posts as well Where people suggested to- 我也浏览过其他职位，其中有人建议-
- load database in each function where i use db. 在我使用数据库的每个函数中加载数据库。
- do not chain the query(which i will try once this is done). 不要链接查询（一旦完成，我会尝试的）。
- change the group_name. 更改group_name。
And i am using XAMPP server, database is fine(i am seeing the table,data in it). 我正在使用XAMPP服务器，数据库很好（我正在查看表，数据）。 did all,still i get error!! 做了所有，仍然我得到错误！

试试这个：保持大小写为真$ this-> load-> model（“ Testquery”，“，TRUE）;

You must need to load the database . 您必须需要加载数据库。
class Testdb extends CI_Controller
{
function __construct() {
parent::__construct();
$this->load->database();
$this->load->model("testquery");
}
public function Index()
{
$data['results'] = $this->testquery->query1();
$this->load->view("view_db");
}
}

Add __construct() methods to both controller and model. 将__construct()方法添加到控制器和模型。 You don't need to omit those. 您无需忽略这些。
