Access Database Help
« on: March 21, 2007, 07:47:09 AM »
I have an access database that contains a main table in which I have defined a primary key (Job_Num) as an autonumber field (no duplicates). Initially I had split this table into multiple tables due to the quantity of fields (especially text fields) that were required and I used the primary key to establish the relationships. I brought the table (despite my desire to do this) back together due to the fact that someone else will be the maintainer of this database in the future. *Shudder*
The input form Iím using is composed of a primary form with three subforms. (This is due to the large quantities of controls). The field Iím using to link the subform to the master form is this Job_Num field, however what Iím seeing is that the information entered into the subform is trying to be saved back to the table as a separate record using the same job number, which then fails because it would create a duplicate entry. I feel like the answer is probably staring me in the face, so if anyone has a suggestion or answer, Iíd really appreciate the help. Also I really need to get this database released today, if possibleÖit was due yesterday.

Have you got anywhere with solving this problem?  Just wondering before I spend time having a play.

Off the top of my head I can't see anything wrong with what you have. You might try adding an invisible Job_Num field to each form as well as the main form so that the job numbers stay in sync. Access is weird like that at times.

Thanks for looking at it.  :-)
I did end up getting it complete (and issued) by switching to Plan B which was to use a tabbed form and get rid of the subforms altogether. I had to recreate all the controls since Access would not allow me to copy/paste from the existing form into the tabbed pages. :-(
Access has some unique quirks...

hey Arizona , sup..

I take it you get this error when creating NEW records? It seems to work fine with the existing records you have inputted (is that even a word), .. hmm. Anyhow, the reason you get the error is because the Main form must be commited (saved) back to the table.

heres what I did to fix it, ..

Insert this event into all 3 of your subforms:
frmContractor_Eval_Section1
frmContractor_Eval_Section3
frmContractor_Eval_Section5


Code: [Select]
Private Sub Form_BeforeInsert(Cancel As Integer)
  If Me.Parent.NewRecord Then
    Cancel = True
    MsgBox "Enter the main form record first."
  End If
End Sub

and insert this event into your main form:
frmContractor_Evaluation
Code: [Select]
Private Sub Form_AfterInsert()
  DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70
    Me.frmContractor_Eval_Section1.Requery
    Me.frmContractor_Eval_Section3.Requery
    Me.frmContractor_Eval_Section5.Requery
End Sub
