php - Codeigniter activerecord 查询连续运行

Question

当我尝试运行以下查询时，它永远不会返回任何内容，它只会继续运行。我做错了什么？

$this->db->distinct('customer.Name')
                    ->from('customer')
                    ->from('invoicelinedetail')
                    ->from('invoice')
                    ->from('iteminventory')
                    ->where('invoice.CustomerRef_ListID = customer.ListID')
                    ->where('invoicelinedetail.IDKEY = invoice.TxnID')
                    ->where('invoicelinedetail.ItemRef_ListID =', $id)
                    ->order_by('customer.Name', 'desc');
$query = $this->db->get();

Answer 1

在$this->db->get();您需要检索结果之后

为此，请设置$query=为以下选项之一：

$this->db->result_array(); //returns array
$this->db->row_array(); //returns single row as array

$this->db->result(); //returns object
$this->db->row(); //returns single row as object
