Controller

class demo extends CI_Controller
{
    function getRecords()
    {
        $offset = trim($this->input->get('off'));
        $this->load->model('demo_model');
        $data = $this->demo_model->get_messages($offset);
        $return = $this->load->view('demo_view',array('records'=>$data),true);
        die($return);
    }   
}

Model

class demo_model extends CI_Model
{
    function get_messages($offset = 0)
    {
        $q = $this->db->query(" select Id,cloum2 from table");

        //  want to use ID from above query in to second query

        //  Like sql="select * from table where id='$id'" ; 

        //  and how i pass the separate result for both query inthe view

    return $q->result_array();
     }

}

View demo_view;

<?php foreach($records as $row) :?>
 <div> do something with $row </div>

 <div> //want use second query foreach here  </div>
<?php endforeach ;?>

Both queries will return PHP arrays so you can do something like.

MODEL

function get_messages($offset = 0)
{
    $q = $this->db->query(" select Id,cloum2 from table");
   return $q->result_array();
 }

 function get_id($id){
    $q = $this->db->query("select * from table where id='$id'");
   return $q->result_array();
  }

CONTROLLER

  class demo extends CI_Controller{
      function getRecords(){
            $offset = trim($this->input->get('off'));
           $this->load->model('demo_model');
           $data = $this->demo_model->get_messages($offset);
           for($c=0;$c<count($data);$c++){
              $data[$c]['innerRow']=$this->demo_model->get_id($data[$c]['id']);
           }
           $return = $this->load->view('demo_view',array('records'=>$data),true);
           die($return);
     }

VIEW

     <?php foreach($records as $row) :?>
          <div> do something with $row </div>
         <div>  
             <?php foreach($row['innerRow'] as $innerrow) :?>
              ......
             <?php endforeach ;?>
         </div>

     <?php endforeach ;?>

(But this isn’t such a good idea as you will run a bunch of queries to the model. Its better to think of a nicer query)
