Question

例如，我有以下时间插入：

7 am to 12pm

我数据库中的数据是：

8 am to 9 am ,
11 am to 1 pm ,
5 am to 7 am

我需要在'WHERE'语句中添加'SELECT'语句，以便在返回值时表示当前时间已经为'RESERVED'，如果不是则为AVAILABLE ' 1}}

我目前的代码是

select eventDate,timestart,timeend from eventcalendar where eventDate='$eventdate' and
 ((Cast('$timestart' as time) > timestart  and Cast('$timestart' as time) < timeend) or  
 (Cast('$timeend' as time) > timestart  and Cast('$timeend' as time) < timeend)) or 
((Cast('$timestart' as time) between timestart and timeend) or ((Cast('$timeend' as time) between timestart and timeend)))

Answer 1

我终于通过添加和反转给定的

来解决它

"select eventDate,timestart,timeend from eventcalendar where eventDate='$eventdate' and 
 ((Cast('$timestart' as time) > timestart  and Cast('$timestart' as time) < timeend) or  
 (Cast('$timeend' as time) > timestart  and Cast('$timeend' as time) < timeend)) or 

  (timestart >  Cast('$timestart' as time) and timestart < Cast('$timeend' as time))  or
(timeend >  Cast('$timestart' as time) and timeend < Cast('$timeend' as time))   "

MySql和PHP时间重叠
