Question

我试图总结total_amount，total_tax，amount_inc_tax和逐月，计算出现错误，它必须是我选择和总结各个列的方式，也许有更好的方法来总结但我不是确定怎么做，如果你能帮助我真的很感激。

数据库结构

我的模特页面..

public function get_all_purchase_order_analysis(){
       $this->db->select('*');      
       $this->db->select('SUM(total_amount) AS total_amount', FALSE);
       $this->db->select('SUM(total_tax) AS total_tax', FALSE);
       $this->db->select('SUM(amount_inc_tax) AS amount_inc_tax', FALSE);

       $this->db->select('MONTH(stoma_purchase_orders.delivery_date) AS pmonth, YEAR(stoma_purchase_orders.delivery_date) AS pyear');

       $this->db->from('purchase_orders'); 
           $this->db->where('storeid', $storeid);
       $this->db->where('status', 'Yes');       

      $this->db->group_by('pmonth, pyear');           
       $result=$this->db->get();
      return $result->result_array();
    }

我的控制器页面..

public function report() {  
        if($this->input->post('submit')) {

            $this->data['reports']=  $this->orderings->get_report($this->input->post('date_from'), $this->input->post('date_to'), $this->input->post('supplierid'));

        } else {
            $this->data['reports']=  $this->orderings->get_report();
        }

        $this->load->view('ordering/report', $this->data);

     }
