INSERT INTO table from form with checkboxes - sql

Question

I would like to insert multiple entries into a table using a single form.
Desired outcome:
DESTINATION_TABLE
DATE | PLACE | THEME | PARTICIPANT
dd.mm.yyyy A X 1
dd.mm.yyyy A X 2
dd.mm.yyyy B Y 3
PLACE and PARTICIPANT are to be selected from values contained in other tables, while DATE and THEME are entered using text boxes. Only one value is to be inserted into the table at a time for DATE, PLACE and THEME, but I would like to be able to insert multiple PARTICIPANT, with a new row for each PARTICIPANT selected.
Adding new entries for DATE, PLACE and THEME via a form works (using CurrentDb.Execute "INSERT INTO...).
How can I create a form that would let me select PARTICIPANT from a subform (ideally with checkboxes) filtered from the value in PLACE, and add an entry in DESTINATION_TABLE for each PARTICIPANT selected ?

Answer 1

One simple way of doing it, with your current setup is to:
add a Yes/No field to your participants table, default to No. We'll call this field Selected
Bind your subform to the participants table, the user will be able to check each participant from this view(using the Selected field).
From which ever event you're using to save you data(e.g. Button Click), create a recordset(rs) based on the selected participants from the participants table(SELECT * FROM PARTICIPANT WHERE Selected = True. Loop through each record in the recordset(rs) and execute your code CurrentDb.Execute "INSERT INTO...), taking the value of the participant(rs("Participant")) from the recordset.
Once the loop is finished, update the participants table setting the Selected field to No. CurrentDb.Execute "UPDATE PARTICIPANT SET Selected = False WHERE Selected = True"
Refresh/Requery your sub form data if needed
Substitute above object names with yours.
