I am trying to prevent a user entering duplicates of date and time in an appointments table for the same doctor..how do I do this?
View 3 Replies View RelatedHave 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

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
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?
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")

Db.Close

the proper code to prevent duplicate records in my form?
I'm using:

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.
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.
View 2 Replies View RelatedI 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

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

I have a main form with several continuous subforms. Each subform consists of several listbox controls. I would like to require the user to select an item from the listbox before being allowed to move to the next record in the subform, and upon reaching the last record in that continuous subform, to require an entry there in order to move to the first record in the next cont. subform.
As an added bonus, it would be nice, though not necessary, to automatically jump the focus from one record to the next after data is entered. But my basic goal is to avoid skipping records.
Caveat: I cannot use the "required" option in the field to which the control is bound because that field has a default value previously entered using an append query. (The default value basically means "not yet entered" and is not one of the options in the listbox. I am using this because this field is a foreign key in the table, thus it must have a value in order to have a record with which to populate the subform.)
My apologies if this has been asked and answered elsewhere, but I've searched and, while I found a few related threads, they don't quite answer my question. Here they are for reference:

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.
How to give a VBA code for duplicate records is without entry in Subform datasheet. I just used in the screenshot code but that is not working properly. how to change a vba code for without entry duplicate names.
View 11 Replies View RelatedWe 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'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 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.

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!
