controller

 <?php

class Result_controller extends CI_Controller{

    function getall(){

        $this->load->model('result_model');
        $data['query'] = $this->result_model->result_getall();
        // print_r($data['query']); die();


        $this->load->library('pagination');

        $config['base_url'] = 'http://localhost/Surva/index.php/result_controller/getall';
        $config['total_rows'] = $this->db->get('tblanswers, credentials')->num_rows();
        $config['per_page'] = 1;
        $config['num_links'] = 10;


        $this->pagination->initialize($config);

        $data['records'] = $this->db->get('tblanswers, credentials', $config['per_page'], $this->uri->segment(1, 0))->result_array();
        $data['pagination'] = $this->pagination->create_links();
        $this->load->view('result_view', $data);




        }


}

?>

view

   <div>

     </tr>

      <?php endforeach; ?>

     </table>  
     <?php if (isset($pagination))
      {
       echo $pagination;
      // echo "<pre>"; var_dump($query);
       } ?>

model

function result_getall(){

   return $this->db->select('tblanswers.*,credentials.*')
                         ->from('tblanswers, credentials')
                         ->get()
                         ->result_object();

The query doesn't magically know you only want x number of records. Codeigniter is going to display whatever you feed it from the model.

function getall(){

        $this->load->model('result_model');
        // print_r($data['query']); die();


        $this->load->library('pagination');

        $config['base_url'] = 'http://localhost/Surva/index.php/result_controller/getall';
        $config['total_rows'] = $this->db->get('tblanswers, credentials')->num_rows();
        $config['per_page'] = 1;
        $config['num_links'] = 10;
        $config['uri_segment'] = 3; //guessing here, but this is where the uri segment you use to change pages goes.
        if($this->uri->segment('3')) {
        $offest = $this->uri->segment('3');
        } else {
        $offest = 0;
        }
        $data['query'] = $this->result_model->result_getall($config['per_page'],$offset);


        $this->pagination->initialize($config);

        $data['records'] = $this->db->get('tblanswers, credentials', $config['per_page'], $this->uri->segment(1, 0))->result_array();
        $data['pagination'] = $this->pagination->create_links();
        $this->load->view('result_view', $data);




        }



Model:

function result_getall($limit=0,$offset=0){

   if($limit != 0)
   {
   return $this->db->select('tblanswers.*,credentials.*')
                         ->from('tblanswers, credentials')
                         ->limit($limit, $offset)
                         ->get()
                         ->result_object();
   } else {
   return $this->db->select('tblanswers.*,credentials.*')
                         ->from('tblanswers, credentials')
                         ->get()
                         ->result_object();
   }

Notice in the controller I'm passing the offset and the per page to the model, then using them to limit the returns in the model itself.
