PHP的MySQL的选择结果，没有在两个日期之间重新记录

Question

I have a table called "bookings" with rooms id & booking date

as

ID        Date
1         2018-04-20
1         2018-04-21
2         2018-04-20
4         2018-04-01
4         2018-04-02
4         2018-04-09

In html the user input the check in date and checkout date

what i want to do is find all rooms id's that has no dates equal or in between the check in and check out input dates...

for example if user input check in as: 2018-04-19 and checkout: 2018-04-21 then result should be : 4

how can i do this ?

Answer 1

您可以使用NOT BETWEEN ：

SELECT * FROM `bookings` WHERE `date` NOT BETWEEN ? AND ?
