Updating two or more tables in access - ms-access

Question

I have two tables which both include a Yes/No type column. I wish to update both these columns using one form.
I do not want to use a subform design because I only want a few fields to show up in the form, not all fields from both tables.

Answer 1

Here is a description of a form/subform approach which you may be able to build on.
Save this query as qryCustomers:
SELECT
cust.CustomerID,
cust.Title,
cust.LastName,
cust.Postcode,
cust.CardNumber,
cust.ExpDate,
cust.SecurityCode
FROM CustomersT AS cust;
Save this query as qryBookings:
SELECT
bk.BookingNumber,
bk.CustomerID,
bk.DateBooked,
bk.Nights,
bk.Price,
bk.Total,
bk.CheckInDate,
bk.CheckedOutDate
FROM BookingsT AS bk;
Create a new form which uses qryBookings as its records source. Choose "Continuous Forms" as the Default View property from the Format tab of the form's property sheet. After you add and arrange the data fields as you wish, save the form with the name fsubBookings.
Create another form which uses qryCustomers as its record source. Choose "Single Form" as the form's Default View property. Lay out your form's fields then add a subform control. Assign fsubBookings as the "Source Object" property (find that property on the Data tab of the subcontrol's property sheet). Use CustomerID for both the "Link Master Fields" and "Link Child Fields" properties.
Cross your fingers and switch the main form from Design to Form View. Hopefully you will see information for one customer in the main form and any bookings for that customer displayed in the subform. You can add new bookings for that customer in the subform.
If this suggestion proves to be a reasonable starting point, you can later adapt it to include what you need from RoomTypesT. But for now, I tried to keep this as simple as possible.
