只有一个简单的解决方法,丑陋,不够优雅,但是在这种情况下它可以工作:
$original_reserved = $this->db->_reserved_identifiers;$this->db->_reserved_identifiers[] = 5;$this->db->_reserved_identifiers[] = 1;// or any other values$this->db->join('with critical values and conditions');// some db-stuff$this->db->_reserved_identifiers = $original_reserved;如果有人知道更好,请显示出来!
