Dear Friends,

How to select all columns dynamically from stored procedure in codeigniter. I called like this: its not working

What I have tried:

Modal:
$query = $this->db->query(CALL chef_allProducts());
return $query;

View:
foreach($field->result() as $row ):
echo $row;
endforeach;

Controller:
$data['field'] = $this->Excelex->get_field();
$this->load->view('excel', $data);
