Hotel Booking Project Delemma

[Abe]

I am having a dilemma with a Hotel Booking Project which is
a small part of a larger project.
If someone can help me with this, or refer me to a sample DB
it would be seriously appreciated!

I have my tables set up as follows.
tblMembers one to many > tblHotelBookingsToMembers
tblHotelBookings one to many > tblHotelBookingsToMembers
(This is setup in the same manner as the Products, Order Details,
Orders tables in the Northwind DB)

In the tblHotelBookings I have fields to capture Number of Nights,
& Persons for each booking
If two members are staying in the same room,
I book them each individually under the same HotelBooingID
in tblHotelBookings
So let's say that HotelBookingID 1001 has 3 Nights & 2 Persons.

Because each member (John & Mary) is linked to HotelBookingID 1001,
when I try to create a report or query, that sums the number of room nights
and persons, I get duplicate values. 6 nights & 4 persons

Essentially I am trying to figure out how I can book two Members into
the same hotel (specific room #s aren't captured) so that each member has
a booking in my DB and I can design a report that will show the number of
persons & nights for each booking without duplicates. This info has to be
passed on to the Hotel.
Lets see if I can be more clear...
If one member (John) is booked, but has a second person (i.e. Spouse)
staying with him who is NOT a Member, then I do NOT need to
show a booking for that second person in my DB.
I simply indicate 2 persons. So I only have ONE booking. No problem.
But if his spouse is a member then I must also book that person into the DB,
which creates 2 members for the same HotelBookingID

Any advice or help is welcome!
Thank You!

PS: If more clarity is needed, feel free to indicate so.

hi,

you can add the DISTINCT clause in the query serving data to the report.
It omits records that contain duplicate data in the selected fields. To be
included in the results of the query, the values for each field listed in the
SELECT statement must be unique. For example, several employees listed in an
Employees table may have the same last name. If two records contain Smith in
the LastName field, the following SQL statement returns only one record that
contains Smith:
SELECT DISTINCT
LastName
FROM Employees;

If you omit DISTINCT, this query returns both Smith records.

If the SELECT clause contains more than one field, the combination of values
from all fields must be unique for a given record to be included in the
results.

Kind regards,

I was under the impression that commercial solicitations
were not allowed on these Groups. But I could be wrong
So, being that its ThanksGiving wekend here in Canada,
I will say thanks, but I'm not interested.

Thanks for the reply Haris,
I think I understand what you are saying, however the problem arises
when there are two different people assigned to One Hotel Booking,
as you indicate about the 2 Smiths.

For Example: Smith and Jones booked into the same Hotel as a double
occupancy
So the HotelBookingID record shows 2 Persons 4 Nights
When I try to design a report (or Query) that will sum all the Nights &
Persons,
I get duplicate values.

Here is a more detailed example. This is a Double Occupancy.
Smith Sheraton Hotel In Oct 10 Out Oct 14 4 Nights 2 Persons
Jones Sheraton Hotel In Oct 10 Out Oct 14 4 Nights 2 Persons
These two people are staing in the same room
So Smith and Jones come from the Member Table & are linked to the
HotelBookings via the tblHotelBookingsToMembers. The HotelBooking Detail
is only one record, but when I design a query to show the people staying at
that
hotel I get the 2 records as shown in the above example.
That's OK I understand why.
But, Here's the problem; I have to give a report to the Hotel that sums All
the
bookings (which includes others). When I design my report to sum the Nights
and Persons to give to the hotel I get 8 Nights & 4 Persons for the above
booking

I'm beginning to think that I am going about this with a faulty method.
That's why im looking for some advice. Sorry if I confused you even more.

Thanks

You aren't wrong. Commerical solicitatation is not welcome in these groups.

Steve, the poster making the offer, has been told many times by many people
that his solicitations in these newsgroups are inappropriate, but he ignores
us all.

Glad to see you're not interested in using a service that has to attract
business using such questionable practices.

From Abe :

Well, one quick and simple way would be to add a field to the
tblHotelBookings indicating it is a 'combined' booking (or something
like that). Simple yes/no field would do.
Smith has this value set to No and Jones set to Yes. Then, sum up all
the fields that have this field set to no.

Another approach would be to create a query to sum the totals.
If your reservations table has fields for room (x), date (y) in and
date (z) out, you could query it and use distinct to get x, y and z
only one time. However, problems might rise when you have mister Smith
from Thursdat till Sunday and miss Smith for only Saturdaynight because
you will have to have more logic in the query. Not undoable though.

I think the first solution would be the easiest since that will show
mister Smith for 3 nights and miss Smith for 1 night. With the combined
booking field set to Yes for miss Smith and thus leaving her out of the
totals.
