Hi folks, I have this situation: a table with patients information and IDs, and a table with evaluations for those patients (identified by ID). I am trying to make it so that the user can't add the same evaluation twice. I want to do it by checking if there is already an evaluation for that patient with the same date. I know how to show evaluations only for a patient, but I don't know how to check if the value entered by the user in the date field is a duplicate (case in which he shouldn't be allowed to enter it). I assume this is done somehow through the "validation rule" property? But how should the expression be? Thanks a lot!
i managed to get checking for duplicate record by ONE field ie member_no
code :
If DCount("*", "runner", "member_no = " & Me.member_no) > 1 Then MsgBox " This member is already exist!" & vbCrLf Me.c_memberid.SetFocus Else DoCmd.CancelEvent End If
how i want to get checking duplicate record by TWO fields ie member_no and run_no ?
I have a form - see attached image. The first text box is called Job_No. When a number is entered here how can I check that the number doesn't already exist when the user tabs to the next box. Then if it does exist display a custom message to the effect "This already exists" and not the Access default duplicate error message.
I have a database where a user imports data into a table monthly. She saves the Excel file and then clicks a button in Access to import the data. My instructions say to only click that button once, but so far, she has clicked it THREE TIMES, thus importing the data three times. How can I prevent this? Here is a copy of my import code:
Option Compare Database Option Explicit
Public Function ImportTableData() On Error GoTo ImportTableData_Err
Dim strPeriod1 As String Dim strMM1 As String Dim strYY1 As String Dim strYYYY As String Dim strFormName As String Dim strMDPath As String Dim strMDFileName As String Dim strDCPath As String Dim strDCFileName As String
'No Warnings DoCmd.SetWarnings False
'Import Current Month data in a temporary table DoCmd.OpenForm "frmEnterAgingDates", , , , acFormReadOnly, acHidden strFormName = "Forms!frmEnterAgingDates" strPeriod1 = Forms!frmEnterAgingDates.Period1.Value strPeriod1 = Format(strPeriod1, "mmddyyyy") strMM1 = Left(strPeriod1, 2) strYY1 = Right(strPeriod1, 2) strYYYY = Right(strPeriod1, 4) strMDPath = "S:FinanceAccounting OperationsNational AccountsAccount Recs116405.100 and 117630.300116405.100-AR Due from PAR Plans NASCO" strMDFileName = "MD AR Due from PAR Plans_" & strMM1 & strYY1 & ".xls" strDCPath = "S:FinanceAccounting OperationsNational AccountsAccount Recs116405.100 and 117630.300117630.300-AR NASCO Refund Due from PAR Plans117630-2007" strDCFileName = "DC AR Due from PAR Plans_" & strMM1 & strYY1 & ".xls"
I'm pretty new to Access, so please overlook any stupid questions :) I have a data entry form that has one field that cannot be a duplicate. So, in the table I have it Indexed with No duplicates. The problem is that the form doesn't notify the user that they have entered duplicate information until they close the form. So the 10 minutes they spent filling it out is wasted. So, after consulting various posts, I did a BeforeUpdate event with the following code: (the field that must be unique is called "LS Number", in the form "Q and D" based on the table "Q and D Database")
Private Sub LS_Number_BeforeUpdate(Cancel As Integer) On Error GoTo LS_Number_BeforeUpdate_Err
If (DLookup("[LS Number]", "Q and D Database", "[LS Number]=Forms![Q and D]![LS Number]")) Then MsgBox "The LS Number you entered already exists. Enter a unique LS Number", vbInformation, "Duplicate LS Number"
When I test this by entering a duplicate LS Number, it gives me the error "Type Mismatch." Unfortunately, I have no idea what this means, nor do I know how to fix it.
I have a problem where in a table called tblPatientLanguage that contains three fields
PatientLanguageID PatientID LanguageID
a patient who is identified by PatientID can speak several languages identified by the LanguageID.
The problem is with my current form and code
For Each varSelected In Me!lstLanguage.ItemsSelected rs.AddNew rs("PatientID") = [Forms]![frmPatientDemographics]![PatientID] rs("LanguageID") = Me!lstLanguage.ItemData(varSelected) rs.Update Next varSelected
when the user click on the command button called cmdOK it will put the data in the table "tblPatientLanguage" and corresponding fields. without checking to see if there is already a duplicate languageID that corresponds to the same patientID in the table
This has lead to duplicates in the table
example PatientID = 9
if I look in the table I will see 7 entries that say
PatientID = 9 and LangaugeID = 7
I want to prevent this from happening with and if statement I could make both the PatientID and LanguageID primary keys this would prevent this from happening. But I would rather do it in the VBA code? This way in will move thorugh the selections without poping an error and the person inputing the date. Any ideas sorry for being long winded. I attached the database.
PS. If looking at the database you have to use form frmPatientDemographics and click on the language link
I have a simple database that I put my execptions in for the day for scanning. Is there a way that my serial field on my forum can check to see if someone already scanned that serial for that day using the "On Lost Focus" event.
I need to create a record of Users. I created a form with fields containing Username,FirstName,LastName & Email Address wherein the UserName is equals the value of the fields FirstName & LastName. I have a save command button and when I click it, I want it to be able to check if the new entry has a similar UserName that exists in the database, if it exists then it will allow me to edit the UserName and then save the data otherwise will allow me to save it.
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....
I'm in need a of a check-in/check-out application for my company. We have about 550-600 employees at any given time and our turnover is about 20-30% per year. Our check-in/check-out process requires our employees to personally visit between 30-40 areas in our company (personnel, safety, credentials, parking, insurance, etc) within the first month of employment. This is currently done manually and is a huge drain on labor, especially when check-in sheets are lost, misplaced or, in some cases, forged.
I'm looking to build a database that would be intranet based, password secure (by check-in area) that would allow the new employee to present at a particular check-in, check-out site, complete that portion of the check-in/out process and then allow the person responsible for the check-in/out to enter the status into the database. At any point in the process, I would want to know the status of the person checking in/out (how long they've been checking in/out and what portion of the process have they completed).
Hi I have sendkey "{f7}" on loss focus. this works great as a spell check but then I get the mesage box that spell check is complete. How do I stop this box from occuring?
I have a table with duplicate rows. How do I de-duplicate the table so that there are no duplicates and find out how many duplicates there were in the table.
Please i am trying to create a form that will keep records of perspnnel but i want a situation whereby if someone enters a last name and first name that is already in the record, the database should send a message telling the user that such a name exists.

Hi All, I have a table that has a device column and a tag # column, I want to pull out a report that shows duplicate tag # for different devices, the tag # can only be assigned to one device, I received an excel sheet that has to be fixed, I have the sheet in an access table. Please help. For example: device 123 and device 345 have tag #abc. I can’t simply create a query to show duplicate for tag# because I can have duplicate # only if it’s the same device.

I currently have a table that had 30 fields, the unique fields are survey, date, and business name. I'd like to create a query that will display all of these records so that i can get rid of them. They were imported from another table that another user created. If survey, date, and business name are identical i'd like to get rid of them.
i have a table with 3 fields: ID, line_item, and pay_app.
line_item and pay_app are linked to other tables in a one-to-many.
For every pay_app, there can be up to 100 line_items. However, I only want each line item to appear once (at most) in each pay_app. I want to prevent the same line item from showing up multiple times in the same pay_app. Essentially, I want to prevent duplicate entries, but with a stipulation, if that makes sense.
So this is a very basic question, listen up: I have only one table in my database. The table contains several text fields ( about 8 ). The table is filled with very very much data. The problem is that i have a multiple instances of the same data ( i mean apsolutly same, all the fields are same ) so i need to delete copies. Help please. Those copies are making me mad :mad:
I need to make a database which wont allow any double bookings.
I've got all my bookings in a query and when a new date is entered (via a new bookings form) I need to make sure that date entered doesn't already exist in the query. I have tried a DLookup but it didn't work, however that is more than likely to be a user error, heh.
I've jumped in at the deep end doing this database. I've only done a few step by step databases before hand and the Access Help has sometimes helped my problems but I just can't find the solution on my own for this, I need somebody elses help.
Thanks a lot

EDIT: sorry if this is in the wrong area, I couldnt think where to put it
Hi I've just signed up to the forum. I'm currently working on a booking system, where clients can make appointments. However as I am fairly new to access, I would like to know how I can inforce some sort of validation where for example if a client makes an appointment on 17/02/08, then it checks to see if there are any current appointments of theirs on the day, if there is, then an error message would occur
Hi, doing my project at college, decided to do a EPOS simulator for my sisters business based around barcodes etc and tied to a database. i've just knocked up something after normalising my data to prototype it to see if it is viable. I'm having problems with duplicate field entries. My db consists of essentially 4 tables at this point:
Transaction: Transaction Number, Date, User ID, Transaction Total
Transaction/Product - a compound key which is to manage the many to many that exists between Product and Transaction tables.
I am wanting to allow multiple entries for the same item, i.e. multiple scans, not a single sacn followed by a quantity. I keep getting an error message though that syas I am duplicating fields. I have tried altering the Index property for the fields in the Product/Transaction table but htis has had little effect.
Any thoughts please as to how to do this? I have attached the db for examination.
