Question

我有一个有趣的要求，希望有人能指导我们实现结果！ TIA。

表格

Student   Date & Time      ClassAttended  Session

Joel      07/21 10:00AM    NO             Single
Joel      07/22 10:00AM    YES            Multiple

Joel      07/20 02:00PM    YES            Multiple
Joel      07/20 03:00PM    NO             Multiple

期望的结果：

Student   Date & Time      ClassAttended  Session
Joel      07/21 10:00AM    NO             Single
Joel      07/22 11:00AM    NO             Multiple
Joel      07/22 03:00PM    NO             Multiple

我的目标是提出以上结果，无论有没有Session列的存在！
