In my opinion your tables doesn't look good. Why is HotelName should come in any of the tables? Is it it a multi-tenancy application? Meaning a system which would be used by many hotels? If yes then you should have only Ids and play with these Ids only. For example: tblHotel tblHotelRoom tblClient tblClientBooking etc. Each will have it's own Id column and only that column will be copied in every other column. So no HotelName in more than one table which tblHotel. Hope you get it. tblHotel -> Id HotelName Address Phone Email etc. Everything about hotel and nothing else. tblHotelRoom -> Id HotelId (from above) RoomTypeId RoomPriceId etc. tblClient -> Id Name Contact details etc. tblClientBooking -> Id ClientId HotelRoomId DateFrom DateTo etc. Now to answer your question: select * from tblHotelRoom hr left outer join tblClientBooking cb on hr.Id = cb.HotelRoomId where cb.HotelRoomId is NULL
