关于如何格式化最后一个表格的任何建议也会受到赞赏，我一直试图在过去一小时内修复它！
答案 0 :(得分：2)
如果我们假设任何航班最多不超过24小时，我们需要做的就是找到星期六开始的航班并在time_in之前获得time_out值。使用MSSQL，它看起来像这样：
select p.name
from Pass_in_trip pit
join Trip t on t.trip_no = pit.trip_no
join Passenger p on pit.ID_psg = p.ID_psg
where DATENAME(dw, pit.date) = 'Saturday'
and t.time_in < t.time_out
使用您的样本数据，这将返回：
Kevin Costner
Kurt Russell
当然，如果旅行时间超过24小时，则无法确定航班是在两个日期之间进行的，因为数据模型并没有记录下来。
对于 Oracle ，你可以按照这样的工作日检查to_char(date, 'DAY') = 'Saturday'我认为 - 我还没有能够测试它。
