Im trying to prevent duplicate records based on a PO # (RA_PO_Nbr), entered from a form. I'm trying to throw a 3022 error when the user attempts to enter a record that already exists, but I dont necessarily have to do it this way.
Code:
Private Sub cmdSubmit_Click()
On Error GoTo cmdSubmit_Click_Error
Dim db As Database
Dim rst As DAO.Recordset
Dim strSQL As String
strSQL = "CompanyPOTable"
[code]....
the proper code to prevent duplicate records in my form?
I'm using:
Private Sub Ctl_Lname_BeforeUpdate(Cancel As Integer)
Dim dupCount As Long
dupCount = DCount("*", "Clients", "[LastName]= '" & Me.[LastName] & "'" & " And " & "[PreferredName] = '" & Me.[PreferredName] & "'")
If dupCount <> 0 Then
Beep
MsgBox
[code]....
"This name already exists in the database. Please check that you are not entering a duplicate person before continuing.", vbOKOnly,
I have some code which creates a record in an external csv file to provide information to upload a vehicle to the website. It works fine with the exception of creating duplicates when, for example an option to amend a record is given to the user before continuing to a new record. The option has to be in place in case there is an error in the specifics of what is important to be recorded in the database and under such circumstances the form code allows the user to tab through the form and correct any errors, but this creates duplicate entries in the csv file as the user has to pass through the 'SavePrintVehPurch_Exit' button a second time after corrections are made.
I am wondering if there is a way of altering the following code to effectively look look to see if the csv record exists and if so correct any changed field information rather than create a whole new record or create a new record where the record does not exist - The record in the csv file is determined by the 'Me.VP_VehRegMark.Value '.
Private Sub SavePrintVehPurch_Exit(Cancel As Integer)
Dim fileText As String
Dim fileName As String
Dim fileNumber As String
fileNumber = FreeFile
[Code] ....
I am wondering about introducing the something like the following ( but can't work out how to clarify comparison of the fields)
If Len(filename(fileText)) = ? Then
Do not change entry
Else
Overwrite the new detail
I have recently started working for a new company and have inherited a nightmare of a system!
I have basic knowledge of Access and have been asked to stop duplicate entries under the same PO Number.
I have tried using DLookups by looking at other posts on the forum with no success.
The input form is called Purchase Order Entry, with the field called PO_No. The table is called Orders, with the field called Purchase Order Number.
I have tried to make the Purchase Order Number in the Orders table, the primary key but an error that it cannot contain a null value appears.
The Purchase orders may not be entered into the database in numerical order also.
We are working on an Access (2007) database that is on a SharePoint Site (2007).
Currently the form is operational, but there is one last thing that would be nice to have.
The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.
In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.
All data is currently bound, so once the user makes a change it is made, no submit button is required.
We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.
TABLE - UPDATED HEADCOUNT
COLUMN in UPDATED HEADCOUNT - EMPID
FORM CELL user will input an EMPID - newEMPID
FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID
So below is what we are trying to do, we are sure there are a few commands missing....
=IIF(newEMPID=dlookup([UPDATED HEADCOUNT]![EMPID]), newEMPID, "Error, EMPID already exists")
i am using a textbox in the main form to transfer the Yr/Mth into the table. (refer to qp.zip)
now my problem is, how do i prevent duplicate records into the table?
e.g: currently whenever i scroll ard the months control in the form, i will get duplicate Mth/Yr into the table. how do i prevent that from happening?
i only want to have updated data inside the Mth/Yr table instead of duplicated Mth/Yr
Public Sub PutInMonthlyRecords()
Dim sql As String
Dim Db As DAO.Database
Dim rs As DAO.Recordset
Dim f As Form
Dim MthYr As String
Set f = Forms!frmQpi
MthYr = f("txtMthYr")
sql = "SELECT * FROM [tblQpiMonthly] WHERE (([tblQpiMonthly].[Input MthYr] = 'MthYr' ));"
Set Db = CurrentDb()
Set rs = Db.OpenRecordset(sql)
If rs.RecordCount = 0 Then
If (f!txtTotalPF) = 0 Then
Exit Sub
End If
rs.AddNew
rs![Input MthYr] = f("txtMthYr")
rs![Monthly TotalPF] = f("txtTotalPF")
rs![Monthly Rejection] = f("txtTotalAvoid")
rs![Monthly TotalAvoid] = f("txtRejection")
rs.Update
Else
If (f!txtTotalPF) = 0 Then
rs.Delete
Exit Sub
End If
rs.Delete
rs.AddNew
rs![Input MthYr] = f("txtMthYr")
rs![Monthly TotalPF] = f("txtTotalPF")
rs![Monthly Rejection] = f("txtTotalAvoid")
rs![Monthly TotalAvoid] = f("txtRejection")
rs.Update
End If
Db.Close
End Sub

View 3 Replies View RelatedI have a table for storing vehicles. The table contains the following fields:
VehicleID
Make
Model
Trim
Build Date Begin
Build Date End
Vehicle Name - a concatenation of 'Make' 'Model' 'Trim' 'Build Date Begin' and 'Build Date End'
The 'Vehicle ID' is the primary key, the rest of the fields can't be indexed with no duplicates. Is there a way of preventing one from saving a duplicate VehicleName on the table since it is a calculated field.
how or what function (DLookup) should I use to prevent duplicate records based on multiple fields? I want to look at data in three fields that can't match existing data in those three fields. It's ok if one or two of the fields match but not all three.

Hi,
I have searched through the whole posts but could not find my query. I have a question related to prevent duplicate data entry in a form field.
I have a Form with 5 fileds on it: SNO, NAME, ROLL NO, CLASS, SECTION.
in the table design i have set the option of NO DUPLICATES on SNO(Autonumber) ROLL NO (text).
I wish to stop a user entering duplicate data in ROLL NO field before he reaches at the last field. What i meant is as soon as a user enters data in ROLL No field, it should check in table if the same data is already there. If the same data is found then it should give a message to prompt user of duplicate data, else it should continue to next field.
I have searched the whole forum but in vain. I am positive that there must be some one who holds the key to this solution.
Regards,
Darno
I am working on a web database with a form which is bound to an underlying web table where the submissions occur.My challenge is that the fields on the form get submitted to the table even before the submit button is clicked regardless of whether the form was completely filled.
My request is that I want the form to only submit to the submission table only when the submit button is clicked.When I searched on the net, the only solutions I got are VBA written code but my web database cannot use VBA code.
VBA code:
Option Compare Database
Option Explicit
Private blnGood As Boolean
Private Sub cmdSave_Click()
blnGood = True
Call DoCmd.RunCommand(acCmdSaveRecord)
blnGood = False
End Sub

I have created a database in microsoft access 2010 to show invoices for different customers in different countries. In doing so, I created using a two subforms in a main form. I have used the "country name" to link the subforms to the main form. When I enter new records into the subforms for a specific country, I realized that a duplicate record of an old record are being created in the subforms. What can I do to prevent this from happening? I tried to change the query link between the main form and subform to "invoice number" but the same problem has occurred.
I am novice to microsoft access 2010 ...
I have an "Returns" master form that contains two subforms. The subforms contain items that we are returning back into our inventory. The underlying queries in each subform show only those records where the "Return Date" is null. The query(s) works fine, except that if there are 3 items that need to be returned there are 3 records that show in the master Returns form. I tried the Totals option in the query but the I need that Return Date on the subform. I only want one Returns master form to show the 3 records (not 3 records of the same master form).

I give an example :

I've set up a booking system and am looking to stop the system recording double bookings.
I've 3 fields, RoomID, Date and Time that need to be searched, however I can't just simply set the properties to No Duplicates (as this would mean a booking cannot be made on the same day at 9:00 and 12:00 for example).
How can I do this?
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

I have a form that contains 5 fields and want to ensure that duplicate information is not entered. I am aware that when creating the form you can set Duplicate Records to No but each record has an AutoID which I assume means that even if the information is the same it will not register as a duplicate record due to the different AutoID.
There should only ever be 5 records entered per day. One for each region
I have created a Sanity Check that is displayed as a sub form that shows if the relevant information has been entered for a given day in Bookings and Backlog but this doesn't stop the user from putting in the same information twice. i.e. the User starts inputting the information gets called away and then trys to put it in again but doesn't check the sub form.
The Table in which the information is stored is called Bookings and Backlog.
The 5 fields on the form which is called Bookings and backlog are
ID (Autonumber)
Date (Short Date)
Combo26 (Text) (5 Regions:- North, South, East, West, Central)
Bookings (Number)
Backlog (Number)
I have put the following statement in AfterUpdate on the Combo26 field
If Me.Date = DLookup("[Bookings and backlog]![Date]", "[Bookings and backlog]", "[Bookings and backlog]![Date]=[Date]") And Me.Region = DLookup("[Bookings and backlog]![Region]", "[Bookings and backlog]", "[Bookings and backlog]![Region]=[Combo26]") Then
'Define Message Box
MsgBox "The Region you have chosen already has data entered for this day." & vbCrLf & vbCrLf & "Please check your records and amend were neccessary.", vbCritical, "USER INPUT ERROR"
Else
End If
However I'm not to hot with writing VBA and probably got something wrong somewhere as it doesn't seem to do anything and lets the user progress regardless. I have tried amending the above script and asked it to look at just one field but this just seems to give the message regardless of the information selected in the Combo box.
Can someone give me an indication as to what I have done wrong so I can put it right and in a language that is easy to understand so that if I have a similar issue later on I don't need to post another question.
Hi all: I currently have a database with a list of clients, and it is to be accessible to others to enter information on clients and to add new ones. However, I want to make it so that the user who wants to add a client can easily search the database for that particular client so that they won't enter a duplicate.
I have created a search function on my form, but then it occurred to me: what if there are two people with the same last name's? At first, I wanted a search operation to display a list of client names, along with their respective ID numbers and possibly a link next to each that would take the user to the corresponding record.
However, I have no idea how to do this, and I'm unsure as to whether or not this is the best way to tackle the problem. Please, someone show me the way!
