 $this->db->select('count(jil_quotemjdetail.qud_requirementid) as quotemjtotal'); 
                $this->db->from('jil_quotemjdetail'); 
               $this->db->join('jil_requirements', 'jil_requirements.rqm_id=jil_quotemjdetail.qud_requirementid', 'left'); 
               $this->db->where('jil_requirements.rqm_id',$row->rqm_id);
                  $query3= $this->db->get()->row_object();
                  $row->quotemj_total = $query3->quotemjtotal;

                   $this->db->select('count(jil_quotejcdetail.qud_requirementid) as quotejctotal'); 
                $this->db->from('jil_quotejcdetail'); 
               $this->db->join('jil_requirements', 'jil_requirements.rqm_id= jil_quotejcdetail.qud_requirementid', 'left'); 
               $this->db->where('jil_requirements.rqm_id',$row->rqm_id);
                  $query4= $this->db->get()->row_object();
                  $row->quotejc_total = $query4->quotejctotal;

                    $this->db->select('count( jil_pocjdetail.pocd_requirementid) as pocjtotal'); 
                $this->db->from('jil_pocjdetail'); 
               $this->db->join('jil_requirements', 'jil_requirements.rqm_id=  jil_pocjdetail.pocd_requirementid', 'left'); 
               $this->db->where('jil_requirements.rqm_id',$row->rqm_id);
                  $query5= $this->db->get()->row_object();
                  $row->pocj_total = $query5->pocjtotal;

                   $this->db->select('count(jil_pojmdetail.pojd_requirementid) as pojmtotal'); 
                $this->db->from('jil_pojmdetail'); 
               $this->db->join('jil_requirements', 'jil_requirements.rqm_id=  jil_pojmdetail.pojd_requirementid', 'left'); 
               $this->db->where('jil_requirements.rqm_id',$row->rqm_id);
                  $query6= $this->db->get()->row_object();
                  $row->pojm_total = $query6->pojmtotal;


                 $data[] = $row;
                        }
                       return $data;
                    }
                    return false;
               }
