如何查看特定日期的预订ID？ [英] How to check the id is booked of for specific days?

问题描述

我有一张桌子，记录如下表所示。

I have a table and records are like below table.

id | list_id |venue_id |name | start_date          | end_date           |start_time |end_time | days 
1  |       1 |  1      |asdf |  2019-02-02 14:05:54| 2019-02-28 14:05:54|05:30      |10:00    | 1,2,3
2  |       7 |  2      |awed |  2019-02-10 15:02:24| 2019-02-20 15:02:24|07:30      |14:00    | 2,5
3  |       7 |  1      |mjgd |  2019-02-04 09:05:54| 2019-02-13 09:05:54|09:30      |18:00    | 4

现在我正在做的是如果在范围内找到，则必须检查开始时间和结束时间范围然后检查start_date和end_date是否在范围内（如果找到），然后显示记录。

Now What I am doing is I have to check the start_time and end_time range if found in the range then check start_date and end_date are in the range if found then display the records.

因此以下查询适用于上述情况

So below query is working for the above scenario

SELECT * FROM batch_list 
WHERE venue_id=1 AND (start_date <= '2019-03-01') AND (start_time <= '13:00:00') AND (end_date >= '2019-02-04') AND (end_time >= '10:00:00')";

现在我有另一列是天。所以我正在做的是 venue_id = 1 被预订为1 、、 2、3、4，然后显示记录。

Now I have one more column which is days. So what I am doing is venue_id=1 is booked for a day which is 1,2,3,4 then display the records.

那么我如何检查ID为1的预定日期呢？

So how do i check the days which is already booked for id 1?

那么我要向用户查询什么以检查表中是否已经有场地ID = 1的日期？

So what query I have to the user it to check the days are already in the table or not of the venue id=1?

function fetchBatches($venue_id,$new_batch_start_date,$new_batch_end_date,$new_batch_start_time,$new_batch_end_time,$days)
    {
$where="venue_id=$venue_id AND (start_date <= '$new_batch_end_date') AND (start_time <= '$new_batch_end_time') AND (end_date >= '$new_batch_start_date') AND (end_time >= '$new_batch_start_time')";

        $result =$this->db->select('*')    
                    ->from('batch_list')
                    ->where($where)
                    ->get()
                    ->result();
            if ($result) {
                 return $result;
            }
            else{
                 return 0;
            }

    }

您能帮我这个忙吗

推荐答案

用于检查一个范围是否与另一个范围重叠的查询可能看起来像这样：

A query to check whether one range overlaps another might look like this:

SELECT x.*
  FROM my_table x
 WHERE x.start_datetime < :end_datetime
   AND x.end\datetime >= :start_datetime;

但实际上您的问题比这更广泛

But really your question is broader than this
