Your database tables don't look like or at least the column name doesn't look like. What is resinvent table for? Is it a reservation or is it a room available table???

You can use MINUS Clause in SQL Statement.
Multiple queries can be put together and their output combined using the minus clause. The Minus clause outputs the rows produced by the first query, after filtering the rows retrieved by the second query.
The statement should be

"SELECT DISTINCT id FROM room MINUS SELECT DISTINCT id FROM resinvent WHERE datein <= '$out' AND dateout => '$in'

The MINUS clause picks up records in the first query after filtering the records retrieved by the second query.
Hope it can help you.

Sir what if the start date is in between but the end date is not?
example room1 is booked for 4 days start date 6/14/2018, end date 6/19/2018.
and the other guest search room start date on 6/18/2018, end date 6/24/2018.
and i used between in my query.
it means room1 is not select or it will not show?, right?
