Question

I cannot figure out how to write query for checking date.

For example;

Rooms table;
room_id, number_of_rooms, checkin(date: 1/05/2012), checkout(date:14/05/2012);

I want to write a query which check for entered date by user (checkin and checkout date) with rooms tabel(checkin and checkout date);

The idea is to know whether period of time entered by user is between check in and check out date of rooms table

Something like this;

select * from romms 
where checkin and checkout date is not among user_entered_checkin and user_entered_checkeout

Answer 1

Maybe

SELECT * FROM rooms
WHERE (checkin IS NOT BETWEEN user_entered_checkin AND user_entered_checkout)
  AND (checkout IS NOT BETWEEN user_entered_checkin AND user_entered_checkout)
