I have a mainform (F_main) and a subform associated (F_place).
F_place is the form of the table T_place.
T_place is linked to F_main by the field "BizNumber". I also have the field "Place" and of course the "Place ID" (primary key) in T_place.
"Place" in linked to a combobox (in F_place).I want to avoid, at a given "BizNumber", the same "place" to be entered in the F_place.
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?
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.
I don't want to allow more than one instance of (HolDte) for the same EmployeeID
PHP Code:
If DLookup("[HolDte]", "tblHour", "[EmployeeID]='" & Me.EmployeeID.Value & "'") <> Me.HolDte.Value Then
Exit Sub
End If
I've got a combo box that lists duplicates. I want the dupes removed.
I went to the Query Builder for my Combo Box and set Unique Values from "No" to "Yes" - Saved, then re-opened the form. It still lists dupes.
I went back into Query Builder and unchecked the box for the Patient_ID (Autonumber) field. I saved it, then viewed the Datasheet for the Query, and it correctly lists the data I want WITHOUT dupes.
However, when I go to Form View, the combo box lists several blank entries..
The entries come back when I re-enable the Autonumber field in the Query.
This is what I currently have...
SELECT DISTINCT Patients.FullName FROM Patients ORDER BY Patients.FullName;
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 currently trying to figure out how to limit the entries into a nested sub form to just one.
for example im making wine collection database, I have a PURCHASE table, a WINE table containing the FK of the PURCHASE PK, and an INVENTORY contain the FK of the WINE PK.
a purchase can contain many wines, but one wine can only be in one inventory location.
I am trying to add all this information with one form. I fill out the purchase details, enter the info of X bottles of wine were in the purchase, and then with one of those wines selected in their subform, i enter the inventory details for that wine. I go select the next wine in the first subform and the inventory nested subform doesnt allow another entry.
I have this code loaded into the On Current event for the main form:
Private Sub Form_Current()
With Me![INVENTORY Subform].Form
If .Recordset.RecordCount = 0 Then
.AllowAdditions = True
[Code] ....

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
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 am using a data entry form to enter new data into one of the tables.How can we prevent entry of duplicate records? Duplicacy shall be checked on the first two fields only.
Please help.
regards
bijon
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,
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
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!
I am putting the student names in a form. I want it to alert me that a name is duplicated. But thats not this simple. For example a name is Jennifer Locus but I type jenifer with one .

I have tblWO_Points and column with firstname and lastname and dateWO column. What code do I use to prevent duplicate dates for same firstname and lastname? Also if a date is a duplicate that it wil ask if you want to go to that record?
Example:
Jane Doe Wednesday, January 07, 2012
Jane Doe Tuesday, January 06, 2012
Mike Doe Wednesday, January 07, 2012
Mike Doe Tuesday, January 06, 2012
Mike Doe Thursday, January 12, 2012
So the same dates can occur for different people but the same dates cannot be recorded for the same person.
I 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.
I am creating essentially a contact database; however, I want to be able to upload new groups into the database from time to time. Some people in the groups may already be listed somewhere else. If I am using an ID number to identify each separate profile; how do I prevent a duplicate profile entry? Will I have to manually check each one? Also if I use the auto-number function, how do I tell access to create a new set of numbers that are different from ones previously assigned? I anticipate about 30 separate groups adding up to around 5,000 names. I don't really care to check that many manually.
