0

When working in Access, whenever I delete a record from one table – it’s corresponding record in another table is also deleted when defined as a one-to-one relationship. This would be normal behavior when I tell it to enforce referential integrity with concerns to deletes and updates (how I understand it). However, it seems to also do it when I leave the enforce referential integrity option for deletes cleared, or when I leave the entire section on referential integrity cleared as well.

Basically, I have one table which is a list of suppliers that is a source for another database application that wasn’t written by myself. I am using this supplier table in my application, augmenting the information stored in the first program with information entered by the user in the second program in a separate table – but linked using a one-to-one relationship (relationship using primary keys in both tables).

I don’t want a delete of the secondary information record to result in the deletion of the data in the primary table – which would cause major issues (to put it mildly) in the first program. Is there a way to do this?

Yes it’s normal behaviour. If your form is based on a query that contains a single one-to-one relationship and you delete a “record” it will delete records in both tables.

You need to suppress the normal delete process and run the delete manually via a custom button.

Private Sub Form_Delete(Cancel As Integer)

  'this cancels all normal deletes'
  Cancel = True

End Sub

Then create a Delete button

Private Sub cmdDelete_Click()

  Dim oDB as DAO.Database

  oDB.Execute "DELETE * FROM tblSupplierInfo WHERE strSupplierID = '" & Me.strSupplierID & "'", dbFailOnError

  Me.Requery

End Sub
