如何在codeigniter中检查行程开始日期和结束日期以及开始时间和结束时间

Question

我正在使用预订系统，用户可以预订他们的汽车，在数据库/表格中添加任何行程之前我想检查日期和时间之间已存在的行程。这是我的模型中的查询。

$this->db->select('trId')
->from('trips')              
->where('carId',$data['carId'])//car Id
 ->where('tripStart <=',$data['tripStart'])//trip start date
->where('tripEnd >= ',$data['tripEnd'])//trip end date
->where('tripStartTime <= ',$data['tripStartTime'])//trip start time
->where('tripStartEnd >=',$data['tripStartEnd'])//trip end time
->get();

我在旅行表中存储了值

tripStart = '2018-03-01'
tripEnd = '2018-03-03'
tripStartTime = '09:00:00'
tripStartEnd = '13:00:00'

Answer 1

select trId from trips 
where carId = value AND 
      (Between tripStart = "value" AND tripEnd = "value") AND
      (Between tripsStartTime = "value" AND tripStartEnd = "value");

这就是你想要的

Answer 2

是的，你可以但在此之前你必须连接sql列进行比较 知道qazxsw poi qazxsw poi

您还需要使用SQL PHP函数将变量组合到datetime中
