Today I'm facing with problem, which I can't solve.



I need to check if two datetimes (2019-04-08 13:30:00 - 2019-04-08 15:30:00 ) are between or overlap two others (2019-04-08 14:00:00 - 2019-04-08 16:00).



Imagine that those datetimes are event's date. We can see that there is an event between 14:00 and 16:00 so we cant' have other between.



I've tried something like this:



SELECT * FROM Rezerwacja WHERE
(('2019-04-08 13:30:00.000' between Start and Stop) OR
('2019-04-08 15:30:00.000' between Start and Stop))


How to check if there is an "event" already ?

          To check for overlaps, you only need 2 conditions, the start or interval A with the end of interval B, and vice versa:



          WHERE
          '2019-04-08 13:30:00.000' < Stop
          AND Start < '2019-04-08 15:30:00.000'
