Question

I have a table:

rommbookinfo
(
   hotel_id
   , room_no
   , start_date
   , end_date
);

Now I have to perform a query to find rooms for the given hotel (hotel id) that are not booked in the date range( ie in between date1 and date2)

SELECT *
FROM tbl_roombook
WHERE hotel_id = '2'
   AND start_date NOT BETWEEN 12/17/2011 AND 12/19/2011 
   OR end_date NOT BETWEEN 12/17/2011 AND 12/19/2011

but it throws the following error:

#1064 - You have an error in your SQL syntax; check the manual that

''SELECT * FROM tbl_roombook WHERE hotel_id='2' AND start_date' at line 1

Answer 1

try

  Select distinct room_no
  From tbl_roombook rb
  Where hotel_id = '$h_id' 
    And Not Exists
      (Select * From tbl_roombook
       Where hotel_id = rb.Hotel_id
           And room_No = rb.room_no
           And start_date <= $date2
           And end_Date >= $date1)
