Notification-Cancellation Of Duplicate Entry
Sep 20, 2005
Greetings,
I am using Access 97 at work, Access 2000 at home. This is a work project.
I have a database that tracks employee awards. One type of award is the Peer Award. An employee can receive more than one award during the reporting period (01 May 05 through 30 April 06), but an employee can nominate someone only ONCE during this period. The query also filters all award for the word PEER in the Award_Type field.
I need a method in my subform (where all of the award info is entered) to display a message if the NOMINATED_BY field contains the name of a nominator more than once. I am using a combobox (cboNominated_By) to select the nominator from a query based on the Employee_Name table.
I had thought of making the field NO DUPLICATES, but cannot do that, as I also keep these records as multi-year archives.
In my query I have as the criteria to limit records for the reporting period above.
In my subform, is there a method to check the combobox that I'm using for a duplicate nominator, then notify the user of this duplicate?
I've seen something similar to what I want in the below thread, but FoFa didn't offer an example of how this would be accomplished;
Notification of Duplicate Records

Thanks all for any assistance you might offer!

I have a Timesheet form where you select your name from a combo, and you select a Timesheet Period from another combo. Then you can enter various details in the sub-forms.
I want to prevent a user from being able to enter two timesheets for the same period. What's the best way of achieving this? I would like a pop-up to appear saying "You have already started a timesheet for this week. Please use the Update Form Dialog"
The timesheet form is bound to tblTimesheets which contains fields TimsheetID, StaffID, and TimesheetPeriodID
In cboNameSelect, StaffID is bound
In cboPeriodSelect, TimesheetPeriodID is bound.
Thanks

I have a table that has (to simplify things) two fields.
[Patient_No] [ID]
BA4206 1067404
BA4206 1067405
BG1013 1067545
BG1013 1067546
BG1013 1067547
BG1111 1078432
I want to be able to count the number entries where the Patient_No is the same and output the query like this:
[Patient_No] [ID] [COUNT]
BA4206 1067404 1
BA4206 1067405 2
BG1013 1067545 1
BG1013 1067546 2
BG1013 1067547 3
BG1111 1078432 1
Hopefully this is just a simple query but for some reason i cannot get it to work.
Any help is much appreciated.
Thanks in advance

Have read through all the threads related to this topic and can't find anything to help. Just want a message box to pop up after entry of first and last names in a form if the string already exists in the database. DLookup works wonderfully for validating on one field, but adding the second field is driving me crazy - Can I use DLookup to check more than one field? The following code gives me the error: "Run time error '2001' - You canceled the previous operation."
Private Sub LastName_AfterUpdate()
Dim x As Variant
x = DLookup("[txtLastName]", "[tblVolunteerInfo]", "[txtLast Name]= '" & Me![LastName] & "'" & " And " & "[txtFirstName] = " & Me![FirstName])
On Error GoTo CustID_Err
If Not IsNull(x) Then
Beep
MsgBox "This name already exists in the database. Please check that you are not entering a duplicate person before continuing.", vbOKOnly, "Duplicate Value"
Cancel = True
End If
CustID_Exit:
Exit Sub
CustID_Err:
MsgBox Error$
Resume CustID_Exit
End Sub
thanks,

I have a Form based on a table of current Players in a football league.
The Form is used to edit, but mainly add new registrations. The fields are...
Surname FirstName Address Suburb Age Club YearRegd
Is it possible in some way to have an alert or message come up stating that the Player is already registered if the Table already contains a player with the same Surname and FirstName only. This would need to happen after the FirstName has been entered as it is the second field after 'Surname'. I'm not sure if Access can do this type of function or not.
I've searched the Forums but have had no luck.
Any advice/assistance is greatly appreciated.
Thank-you very much.

Hi all,
I created a form for entering employee skillset in Accounting.
I have set up three fields - one for Primary Skillset and the other two for secondary skill sets -
The skillsets are -Payables, Receivables, General Ledger, Purchasing etc.
How can I ensure that a user will not enter duplicate values in the three fields.
That is a user will not enter for examply "Payables" in the Primary Skillset, and Secondary Skillset fields.
I tried creating a multiple field index but it does ont appear to work.
I will appreciate all the help.
Thanks

I have struggled with this for so long now I hope someone can help.
I have a form called frm_Collections which is run from the query (qry_Collections). When I type into the Reg field in the Form I would
like the user to know if the Reg details have already been used in a
previous record. The database can have duplicates in this field, however a
"Warning Message" would promt some investigation.
I have tried loads of DLookup on Before Update, but really need setting of
in the right direction.
Thanks

Hi!
I have a form which is based on student records. What I'm trying to get Access to do is to bring up an error message as soon a duplicate student number has been entered. At present I've managed to replace the Access standard error message 3022 with my own by using the following code:
Private Sub Form_Error(DataErr As Integer, Response As Integer)
Const conDuplicateKey = 3022
Dim strMsg As String
If DataErr = conDuplicateKey Then
Response = acDataErrContinue
strMsg = "Duplicated record. Please recheck your data."
MsgBox strMsg
End If
End Sub
However the error message only appears when you try to leave the form (e.g. start a new record). I would like the error message to appear as soon as the user leaves the Student Number text box on the form. Is there anyway to do this?

Hi, I have a cross-ref table (called MFC_CIBC_XREF) which links a bank account to a fund number and a general ledger number. It should be a unique relationship, wherein (the "=" means corresponds/links to)
Bank Account # "=" Fund #
For each bank account, there are sometimes multiple currencies being used, so each currency then links to a general ledger account, such that
Bank Account #.Currency = Fund #.General Ledger #
Sorry, if that's kinda cryptic, but here's an example:
Bank Account - ABCD123
Currencies operated in - CAD, USD
Fund # - F30
Based on the above, ABCD123 "=" F30, and including the general ledger numbers, ABCD123.CAD "=" F30.100, ABCD123.USD "=" F30.8121.
Basically, it's a way to keep track of not just the transactions for a particular bank account, but for the transactions in a particular currency.
Anyway, as I said, it's supposed to be a 1-to-1 relationship: each BankAccount.Currency should correspond to 1 and only 1 Fund.GeneralLedger. However, there are some entries in the table which have each BankAccount.Currency corresponding to multiple General Ledger numbers. Using my example above, ABCD123.CAD has two records in the table, one corresponding to F30.100, and another corresponding to F30.8101. This was probably because F30.8101 used to be linked to a different bank account, that got merged (ie, it might have been linked to ABCD124.CAD that then got merged into ABCD123.CAD).
Now I want to run a query on MFC_CIBC_XREF and find all the records where for each BankAccount.Currency, there is more than one Fund.GeneralLedger. I don't really know that much SQL, and even in Design View, I'm not sure of the statements to use. Any help is much appreciated.

I have a single table in my database and I have to make a form for entering contact details for clients, staff, funding bodies and everyone else into this table. There is a phone number and what code I would use the get it to check if the number already exists.
If it does, I wanted it to return a custom message telling you what entries it already exists for by displaying certain fields so that they can be identified, such as name and organisation, but then I wanted the custom message to allow you to confirm entry of the data anyway. This is because there may have been an error in entry or as some people may be contacted on the same phone number, I want it to allow the option to continue and enter the data anyway.

I have a data entry form linked to a table that records daily catch details (date, invoice number, buyer, kilos, price, etc). For the last 2 years I've been using the no duplicate index on the date field of the table to prevent duplicates, until he (my husband) decided that he wanted to sell his catch to different buyers on the same date.
I've changed the index to allow duplicates but now I need to create a message box which warns that he is entering a duplicate date as he has a history of trying to enter the same info twice. I've found examples of code that warns on duplicate text entries but nothing for duplicate dates?

So now, I'm using the code below to prevent duplicate name entry and it is working great - EXCEPT when I enter a first or last name which contains a ' (ie, O'Tool, O'Malley, O'Hern)...anyone got any ideas for me on how to make this not happen?
The error I get is:
Run Time error '3075'
Syntax error (missing operator) in query expression '[Last Name]='O'Hern' And [First Name]='Lori'.
The code i'm using is:
Private Sub Last_Name_AfterUpdate()
'Check for duplicate first and last name using DCount
If DCount("*", "[Constituents]", "[Last Name]= '" & Me![Last Name] & "' And [First Name] = '" & Me![First Name] & "'") > 0 Then
Beep
MsgBox "This first and last name already exists in the database. Please check that you are not entering a duplicate constituent before continuing.", vbOKOnly, "Duplicate Value"
Cancel = True
End If
CustID_Exit:
Exit Sub
CustID_Err:
MsgBox Error$
Resume CustID_Exit
End Sub

I have a form which saves to a database correctly. It has a key field name called "code".
I can recall the data into a copy of the first form to edit by using the key field "code".
All works well, however, when I click save data from the edit form it does not alter the original data but creates another form but with the same key field called code.

I am trying to create a duplicate of a certain record in a table so that the user can then edit the new record - or old record even as it doesn't matter - as long as one of them is original. The idea is that any revisions / changes are stored the user may of made.

I was using the following code on a field (ItemCode) that was indexed to prevent duplication of records. The intent is that the user will get an error message that a duplicate exists before they enter all the data for the record and get the built in error message that Access 2003 provides when an index violation has occurred.
Code:
Private Sub ItemCode_BeforeUpdate(Cancel As Integer)
Dim Answer As Variant
Answer = DLookup("[ItemCode]", "tblQuestions", "[ItemCode] = '" & Me.ItemCode & "'")
If Not IsNull(Answer) Then
MsgBox "Item Code already exists" & vbCrLf & "Please enter unique Item Code.", vbCritical + vbOKOnly + vbDefaultButton1, "Duplicate"
Cancel = True
Me.ItemCode.Undo
Else:
End If
End Sub
Now, the index for this is based on two fields (ItemCode and Question Group). I would like to display the same message before update but don't know how to include the second field in the syntax.

I have a Form created for Hardware Allocation.
I have following Fields. Allocation ID(PK), HW ID, User ID, HW Status, Assigned Date.
Values of HW Status = Active, Inactive, Decom, In Stock etc.
What I want is explaind below example
HW XXX is allocated to User ABC and the Status is Active.
Now When I want to reallocate the same HW XXX to Another User XYZ then Make the current status as Active. But before doing that the form should force me to change the Status of previous allocated to user ABC to anything other than active. Because One Device can be active to only one user at a time.
i,e Combination of HW ID & HW Status(Active Only) should not be duplicated.

1. I have a database (see attached) with three tables all of them with the same fields. The first three are numbers (InCo_No, Proto_No, Year_No). Each of these fields (numbers) can be the same in the other table(eg. Year_No), but the combination of the three cannot be.
How can I prevent the entry of a duplicate combination of these three fields?
2. I want to have a form to fill the three tables separately, depending the values in the other fields.
How can I do this?
