Try this query. Not sure as I dont have the data to verify. Give it a try.

SQL

select Rooms.RoomId, Rooms.RoomType From Rooms INNER JOIN Reservations ON ( Rooms.RoomId = Reservations.RoomId ) AND GETDATE() NOT BETWEEN Reservations.CheckInDate AND Reservations.CheckOutDate ORDER BY Rooms.RoomType

Thanks, but the querry you gave is to search the reservation to check if there is reservation i guess

i don't have any data in the reservations table, but do have data on rooms table,
How do i search the rooms table and compare it with the reservations table to befor populating the result like

DataTable dt1 = try.Query( "Select Rooms.RoomType, Rooms.PricePerNight From Rooms INNER JOIN Reservations ON (Rooms.RoomId != Reservations.Roomid) ORDER BY Rooms.Roomtype");

if (dt1.Rows.Count > 0)
{
GridResult.DataSource = dt1;
GridResult.DataBind();
}
else
{
LblMessage.Text = "No Rooms Availble";
}
Please help me correct it is wrong

Yes, if the current date is between the checkin and checkout date then there is reservation. It should be NOT between to check for no reservation.
