Tables :: Avoid Double Bookings In Simple Database?
Jun 7, 2013
I work across a number of small venues which have art cases that can be booked for displays. I am trying to build a simple data base to report what space is available and also what art is currently being displayed. The art is usually booked by month, but sometime it can be booked for a week etc.
I have set up 3 tables
Art Inventory
Art Cases by Venue
Art Case Bookings
In the art case booking form, I have set up the start and end date but I cannot figure out how to avoid double bookings of a case? Once I have that worked out I believe I know how to build the required reports for my needs.

I am supposed to make a database for a hotel system, how I could prevent double bookings.
My Reservation Table has the following fields:
Reservation No. (PK)
Room No. (FK)
Customer ID (FK)
Payment ID(FK)
Reservation In Date
Reservation Out Date
Together with preventing double bookings is there a way automatically that can mark in the Room Table, the status as "available" or "booked" automatically by looking at the date today?

hi guys nice site you got here.
I need a bit of help its been over 2 years since I used access in college so have forgot most things.
I want to stop people from making double bookings at the same time on the same date.
I have the following
Booking ID
Teacher ID
Class Room ID
Date Booked
Booked Date
Start Time
End Time
so the booked date, start time and end time is what I need to look but not sure, should I index (no duplicates) for them three?
thanks for the help
I realise there are posts about bookings but more help would be great :)

I have a form which allows the user to book rooms.
On this form, there are the following fields:
BookingID: (Autonumber)
RoomID: Text box
Time:Text Box
Date: Text Box
Class: Text Box
Teacher: Text Box
The form adds this information to the Booking table.
What I'm looking to do is prevent the user from double booking a room,like being able to check if the Room is already booked at that time and date, before the new information is added to the table and the room becomes double booked.
Basically this would be checking the RoomID, Time and Date fields, as everything else is irrelevant. What would be the best way to do this?

2 tables in an Access database
tblPurchases: columns: Index (PK-autonumber)| Store| Product| Cost
data: 1| Staples | Tape | $0.89
2| Staples | Paper | $4.50
3| OfficeMax | Markers | $3.50
4| OfficeMax | Paper | $4.75
5| OfficeMax | Pens | $1.98
tblInfo: columns: Index (PK-autonumber) | Store | Product
The data in the access database tblInfo.Store is queried from tblPurchases.
Here is the query for the rowin my database design view:
SELECT DISTINCT tblPurchases.Index, tblPurchases.Store FROM tblPurchases;
When I am in the database and access the column's pull down, I get ALL records, including duplicates (so OfficeMax is listed 3 times.) How do I get it so I only see
Staples
OfficeMax
in the pull down when in the database?
Thanks!

For some reason I cannot enter decimal values without the number rounding up or down. I've already set it to 'Number' and 'double' and have also tried 'Fixed' set to 2 decimal places. Right now the only way it works is if I set it to 'Text'. However I need to do some calculations with these values eventually.
What's strange is I have another table in the same database that is NOT rounding and is working just fine.

I have a form that utilizes a combo box with 2 options: 0 & 0.5. If I select 0.5 on the combo box the field in the table records it as 2. Why doesn't it reflect as 0.5? And how do I fix it?
This is the general info that I have for the field properties:
Field Size - Double
Decimal Places - 1
Default Value - 0

attributes are
Date Arrive | Date Depart | Room Number | room price
i want to add an total column at the end (i was using the query by example builder) and tried [datedepart] - [datearrive] * [roomprice]
this however doesn't always work well, is there any other way of doing the same function? i can use SQL if that makes life easier

I am trying to create a query that will count the number of bookings in january and a seperate count for the number of bookings in february from a table called booking order. im using the start date as the date to tell which month the booking was in.

Dear Programmers,
I would like to display a page that tells the user that there are no "bookings" for TODAY. It is a restaurant booking database which I have nearly completed. When there are bookings for TODAY, it shows a table with the customers booked for today (that's working ok), but if there aren't any for 'today' when I open that page, it just shows the headings of the table with no customers. I'd like to just display a message (and no table elements) when there aren't any bookings for today. Pretty confusing explanation? sorry bout that.
Of course I'm using a MS Access DB and .asp
Any suggestions?? Thanks very much.
Rod.

Could someone check the following code. i've set up a form for creating regular bookings, and have a field, for which you type in the frequency in days you want the bookings for. (ie, 7 days for every week on that day, 14 for every two weeks etc...) and it seems to work, however it just alters the one record, instead of creating entirely new ones. Could someone please help:
Private Sub cmdCreate_Click()
Dim date2 As Date
Dim period As String
Dim cost2 As Currency
Dim frequency2 As Integer
Do While year = actual_year
date2 = Date_For
period = Time_Period
cost2 = Cost
frequency2 = Frequency
DoCmd.OpenTable "tblRegularBookings"
DoCmd.GoToRecord acDataTable, "tblRegularBookings", acNext
Date_For = date2 + frequency2
Time_Period = period
Cost = cost2
Frequency = frequency2
DoCmd.Close acTable, "tblRegularBookings"
Loop
End Sub
Also, one of the other problems i'm trying to solve is for those who want to create a regular booking but on say every third monday of the month for example.
Thanks very much

Hello. I am trying to create a database where I can enter contributions from members of my church, in order to give them report at year's end.

Hello All,
At work we have a large and messy Contacts list so I decided to set one up using a database.
At present I have 3 tables:-
Companies (custID,companyname,address,etc)
People (nameID,firstname,middlename,lastname,custID)
Phones (phoneID,phonetype,areacode,number,?????)
My problem is this, Some of the phone nos belong to the individuals
and some belong to the company. If a person is replaced at a company I need to reasign the company phone nos to the new person whilst retaining the individuals and their personal phone nos. If a company is deleted I need to delete only the company phone nos. and if a person moves within the company I want the company nos to reasign to the new replacement but keep the personal nos of the individual. Now I see its going to be more complex than I thought.
Can anyone help me with the table layout and links. (nb this is only a simple database relating a person to a company without using departments etc.)
Its main use is to provide phone nos names and addresses quickly.
Many Thanks
Peter
