Message: Undefined variable: query

[eluser]SPeed_FANat1c[/eluser]
I am using codeigniter for long time and want to create new test project and get an error:

Code:
A PHP Error was encountered

Severity: Notice

Message: Undefined variable: query

Filename: controllers/welcome.php

Line Number: 42


My code is simple

Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends CI_Controller {

/**
  * Index Page for this controller.
  *
  * Maps to the following URL
  *   http://example.com/index.php/welcome
  * - or -  
  *   http://example.com/index.php/welcome/index
  * - or -
  * Since this controller is set as the default controller in
  * config/routes.php, it's displayed at http://example.com/
  *
  * So any other public methods not prefixed with an underscore will
  * map to /index.php/welcome/<method_name>
  * @see http://codeigniter.com/user_guide/general/urls.html
  */
public function index()
{


  if (isset($_GET)) {
   echo json_encode($this->get_all());
  }

  //$this->load->view('welcome_message');
  echo 'test';
}

// will use contacts database to not create aditional
private function get_all() {
  $this->load->database();

  $sql = "SELECT name as brand, address as color, tel as max_speed FROM contacts";

  print_r($this->db);

  $this->db->query($sql);

  return $query->result_array();
}


}

and when print $this->db here is result

Question...

why are you doing a query in a controller?

#3
[eluser]SPeed_FANat1c[/eluser]
this was just quick experiment, not real project, so lazy to do the model Smile

#4
[eluser]SPeed_FANat1c[/eluser]
found stupid mistake:

should have wrote

Code:
$query =$this->db->query($sql);
