Question

在开发会议室预订系统时，我在检索可用会议室时遇到错误。

数据库结构为：

表：Meeting_room_bookings

列：id（int），meeting_room_id（int），日期（以MM / DD / YYYY格式的日期），start_time（int），end_time（int）

下面是我的查询，如何根据日期和时间获得可用的房间？

  $this->db->select('meeting_room_id');
  $this->db->from('meeting_room_bookings');

  $this->db->where('date',$date);
  $this->db->where('start_time',$timestamp_start);
  $this->db->or_where('start_time',$timestamp_end);
  $this->db->or_where('end_time',$timestamp_start);
  $this->db->or_where('end_time',$timestamp_end);

  $where1 = "('start_time' <= $timestamp_start) AND ('end_time' >= $timestamp_start)";
  $where2 = "('start_time' <= $timestamp_end) AND ('end_time' >= $timestamp_end)";

  $this->db->or_where($where1);
  $this->db->or_where($where2);

  $data['value1'] = $this->db->get()->result();

Answer 1

if you want to get available meeting rooms you can set a tag 0 for free and 1 for busy for your meeting rooms, if someone book a meeting room set a tag to 1 and then on meeting completion set tag to 0.
