My intention here is to select all entries (Bookings) between "begin" (begin_prefix) and "end" (end_prefix)
BUT! The important thing is:
If I have a booking at 07:25-10:00 - you query for 09:00-10:00 it should still show the booking because it reserves the room until 10 no matter what ..
So ..
07.25-10.00 booking means query for 09:00-10.00 still returns a list of bookings within 09:00-10.00 (which means 07.25-10.00 is included)
public static List<booking> Today(DateTime begin, DateTime end)
{
try
{
IFormatProvider Culturez = new CultureInfo(ConfigurationManager.AppSettings["locale"].ToString(), true);
DateTime begin_prefix = DateTime.ParseExact(begin.ToString(), "dd-MM-yyyy HH:mm:ss", Culturez);
DateTime end_prefix = DateTime.ParseExact(end.ToString(), "dd-MM-yyyy HH:mm:ss", Culturez);
dbDataContext db = new dbDataContext();
// gives bookings BEFORE begin_prefix (why?)
IQueryable<booking> bQ = from b in db.bookings
where begin_prefix >= b.Starts &&
b.Ends <= end_prefix &&
b.Ends > b.Starts &&
b.pointsbookings.Count > 0
select b;
// ^gives bookings BEFORE begin_prefix (why?)
List<booking> bL = bQ.ToList();
return bL;
}
catch (Exception)
{
throw;
}
}
I've tried getting this right for some time now .. Seems everytime I correct it to something new, a new overlap or selection outside the two begin/end dates seem to appear :(
UPDATE CRITERIA and SOURCE: Bookings has to be WITHIN "begin_prefix" and "end_prefix" or on the exact same time ..
.. currently the above code gives me bookings BEFORE begin_prefix date, which is not intentioned! We're in 2011, I got bookings from 2010 as well! **
NEW!! UPDATED:
This is what I have:
SEARCH.START = BOOKING.START
BOOKING.END <= SEARCH.END
... the problem comes up when ..
BOOKING entry: 10:00(Start)-14:00(End)
This means according to above:
08.59 = 10.00
(SEARCH.START = BOOKING.START)
It will never include it. But it should, since this is the same room and the seats are booked individually!
