Forms :: DCount In Forms To Avoid Duplicate Record
May 31, 2014
How can I prevent duplicate records from being added from a form, the dcount in the text field property, trigged before update is where this should be used is what I know but having trouble with the syntax.
I've got the table tblInvnetoryDetail with InvID(AutoNumber), and SerialNumber. The form text field is txtSerialNumber. I've managed this far with the expression
DCount([InvID],"tblinventoryDetail","[txtSerialNumber]=&"'") but this did not work.
How can I get the expression to avoid duplicates.

If expression to determine if a duplicate records has been entered.
DateAte is a date
MealType is a list box (text)
All I want to do is prevent two lunches, etc. from being entered on the same date. Code that results in the message box every time, regardless if a duplicate record or not.
Private Sub MealType_AfterUpdate()
Dim strDA As String
Dim DA As Date
DA = Me.DateAte.Value
strDA = "[DateAte]=" & "#" & DA & "#"
If DCount("[MealType]", "tblmeals", strDA) > 1 Then
[code]....

On my form I've got an afterupdate event that checks if the information entered already exists and this works absolutely fine. However what I would like is the option to go to the existing record if one is found, but I can't get it to work.
This is my code currently;
Code:
Private Sub Job_No_AfterUpdate()
If DCount("*", "PACKING", "[Job No>]='" & Me.[Job No] & "'") > 0 Then
If MsgBox("Job Number already exists! Go to record?", vbYesNo, "DST PLANNER") = vbYes Then
Dim rs As Object
[Code].....
The check for the Job Number works fine but when I click Yes on the message box, the form stays on the current record instead of moving to the existing record.

I have inherited a 5 table database which is associated with membership details and all tables are linked via the membership number which appears in every table..eg
Main Register
membernumber, surname, forename, age etc etc etc
Home address
membernumber, address1, address2, address3, postcode
Business address
membernumber, company name, address1, address2,etc etc etc
Subscription
membernumber, grade, subscription, bank account, etc etc
Training
membernumber, college, results, etc etc
I am informed that it is bad practice to have duplicate data in multiple tables (ie. membernumber field) as updating the data item would be difficult (eg. if the members number needed to be changed for any reason). If this is the case how would I restructure the tables but maintain the link through the membernumber?
I am fairly new to Access....as you can no doubt tell.

I have a form with a duplicate record button to allow records to be copied. I used this code (I think from Allen Browne), but it only copies the last record in the recordset?
If Me.Dirty Then 'Save any changes
Me.Dirty = False
End If
If Me.NewRecord Then 'Check there is a record.
MsgBox "Select a record to duplicate"
[Code] .....

I would like to know what the best way to input a duplicate record is with the exception of 1 field that is used to correspond with the proper parent of the record?
Here is an example of the problem, We receive a letter with pertinent information that corresponds to 30 of our facilities. I would need to enter this 30 times so that when the users of this information run their reports for their facility I can ensure that the letter would be referenced.

error message I am getting when I click on my Duplicate Record button (created through the wizard).
I have two combo boxes on the main form that populates data when the user makes a selection from the combo box. First combo box populates project data and the second combo box populates equipment data. The form is working well with the two combo boxes populating the data into the main table.
Now I would like to add a duplicate record button to copy a record and paste the data as a new record. So, I added a duplicate record button using the wizard and I am receiving the following AfterUpdate error.
Run-time error 3020: Update or CancelUpdate without AddNew or Edit.
This is the code I am using to copy and paste a duplicate record:
Private Sub InputForm_DupRec_Button_Click()
On Error GoTo Err_InputForm_DupRec_Click
DoCmd.RunCommand acCmdSelectRecord
DoCmd.RunCommand acCmdSaveRecord
DoCmd.RunCommand acCmdCopy
DoCmd.RunCommand acCmdPasteAppend
Exit_InputForm_DupRec_Click:
Exit Sub
Err_InputForm_DupRec_Click:
MsgBox Err.Description
Resume Exit_InputForm_DupRec_Click
It seems to be duplicating the data from the first combo box, but not the second one where it errors out.

I have a report which has say two columns - staff number and visit date. For a staff number (which is unique) there may be more than one visit date. But I want to list a staff number only once and not multiple times in the column (but want all the visit dates of course). How can I do that?

I'm working on a form with almost a hundred various fields (it's what my employer needs). He wants to be able to create new records with much of the same information as the old ones by clicking on a button that will copy the information to a new record, then clear certain specific fields (or some process that will safely create the same result). I don't need specifics on how to write the same line of code for each and every field I wish to clear.
Say I have a form with 5 fields: part_number, part_owner, procedure, file_name, and date.
How could I copy the record to keep the fields part_owner and procedure the same, but clear part_number, file_name, and date?
All of the fields are from the same table (no, it's not normalized...).

Currently if an employee attends a mandatory training session the details are entered individually into in a single table which contains all the employees' attendances to training, this is achieved via a bound form.
Works Fine.
My question is, if the training is carried out by a number of employees can this attendance be recorded on one form and assigned to each of the employees who attended?
Using Access 2003

I am creating an access database for recording calls and follow ups for a company
relevant tables
mst_customers
card_call
ID from customers and customer_id from card_call have a one to many with all records of card_call
Although its more elaborate than this, lets get down to the problem
I created a form with a subform that should basically allow selection of customer and based on this, the creation of records in card_call as per customer selected. form and subform are linked by customer_id
Everything is working except a peculiar issue where if i select a customer_id it shows all relevant records + an additional record (usually 1 or 2) that just changes the customer_id for that record.
Example
customer_ID = 2 (combobox bound to column1 and showing name/column2)
output
call_ID | Customer_ID
1 | 2
2 | 2
3| 2
changing customer_id to 4 will change to
1 | 4
(new) |

I am not sure if it is possible to implement this but I would like your input. We get request from client via a web based form which contains a unique ID number called RDEFNumber. When we process the request internally, we use this number to identify the request throughout the process. The request from client contains processing of multiple files which are transmitted to us in different times of the day or days.
Every time we receive a file, an email is sent to the IT team with all the information about the file. We use an internal database to send the email to the IT team and use the RDEFNumber as the identifier in the subject line. What I am trying to do is to add an additional number at the end of the RDEFNumber automatically to differentiate the subject line.
For example, we take "1791" as a RDEFNumber. For the first time we enter 1791 to the database RDEFNumber field, it should check the table "tblRDEF" (record source) for duplicate value. If no Duplicate exists, it should keep the number as same. When we get the next file for processing with the same 1791 number and enter this number in the RDEFNumber field, it should automatically change it to "1791-1" since "1791" already exists in the database. When we get the next file, the number should change to "1791-2" and then "1791-3" and on.

I have a form with a duplicate record button.Sometimes when duplicating a record the duplicate is created but the form remains in edit mode (small pencil in the form margin).I also have a manual record counter on the form which does not refresh to the newest record number following the duplication? Both issues happen together and not independently.
I now have the standard MS Access record counter visible on the form to see whats happening and this always jumps correctly to a new record number when duplication is triggered, so when the problem happens the MS Access counter is showing one more than my own record counter.
If I use the standard MS Access record navigation buttons and go back and then forward by one record, the duplicated record is then corrected. The edit mode pencil is gone and both record counters read the same, which I assume has happened this has forced a save to happen
If Me.Dirty
Then Me.Dirty = False
End If
- in the current event of the form, would solve the problem, but it doesnt make any difference at all, its still no better, or no worse than before?Using CTRL + S removes the pencil, but doesn't correct my bespoke record counter?

I always have a problem with input forms in Access in that I usually end up with an empty excess record which is being created because I do not know how to program this correctly.
I have a Purchase Order Receipt form (frmPurchase). When I receive a certain quantity of an article associated with a lot number (or a serial number) I have another input form opening up (frmLotorSerial), passing to it through Openargs, the article and the quantity received.
Say we receive 10 units of which we want to register the serial number, I want the user to be able to enter a maximum of 10 units (could be 10 records if each record = 1 serial number, but it could be less than 10 if we have several units per lot number), and not one more, into this frmLotorSerial.
The record looks like this:
-key
-artno (article)
-recqty (quantity received)
-date
-warehouse
-lot number
I used the lost_focus event on lot number to check whether the total received quantity in this form matches the total passed to it from the Purchase form, and if it does to stop the input. Since I could not close the window in the code of this event (error 2585) I moved the close command to the current event of the form.
Doing this closes the form all right, but it always creates one record extra, which of course does not carry any information, apart from the date which has a default value of now.
How should I program/what events should I use to:
-test that the user should not go any further (total received in frmLotorSerial = total received in frmPurchase)
-close the window and, above all, not create this extra record.

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 have a tblManualRewardIncident in there I have 3 fields I want to have my staff in put these rewards via a frmRewardIncidentEntry However im concerned over another staff member in putting the same data so I want the form to highlight on update that a duplicate is there already so cancel the data entry.
The 3 fields that need to check and match are StrataID , DateOfIncident , EndDateOfIncident these are all in the tblManualRewardIncident and appear as buttons in the form frmRewardIncidentEntry the buttons are as follows
cboStrataID , txtDateOfIncident , txtEndDateOfIncident
I want the VBA to run when I CLICK another button on same form cboSQCDP..All 3 fields must match exactly to flag a issue.
StrataID , DateOfIncident , EndDateOfIncident from tblManualRewardIncident
If it doesn't find a match continue and add the inputs in these boxes to the table if it finds a match flag a message and delete the data from the form.

Hi All,
basically i'm new to access, i am not a programmer and have been asked (told) to do an access (a few) for our office,
OK what I have is a very very simple database, we add in the post that we post out every day. I have two fields called Postage Paid and Stamp Required. I have used a Dcount to count how many have Postage Paid and how many require a stamp (Stamp Required).
What I want is to add the totals for the day that i enter them, i don't need to store that data, just to tally up the totals for the day i enter them...

I think I read somewhere that DCount will not count blank cells, but when I try to do it - it counts everything.
Here is my formula:
=DCount("[E-Mail]","Detail","Not IsNull([E-Mail])" & " AND [Primary] = [Products]![Product Code]")
Basically, I want to count the number of email addresses in the E-Mail column of my Detail table IF the Primary column (also in the Detail table) equals the product code on my form AND if there is something in the E-Mail column for that line. When I did the above formula - and I've done a bunch of different variations - it keeps counting all lines that match the product code.

DCount function.
Code:
Me.ImprovementNotice5DayCount = DCount("[txtReferralReason]", "qryRTOFileReferralPopupCount", "[ComplianceTargetDate]-[DateNow]<=5")
I am not sure where I have gone wrong.
What I would like Dcount to count are those dates in the ComplianceTargetDate form control that are <=5 to the DateNow form control.
I get a count of 3 when there is only one. I may have the syntax of the Dcount wrong.

I am working with MS Access 2003. I have a form (frmCalendar) with a textbox (tbDay) and a combobox (cmbLineName)
I want to count the number of records based on the criteria from cmbLineName, and show the result in tbDate. Inside the Control Source of tbDate I put in the following:
=DCount("[EncounterID]","tblEncounters","[LineName] = ' " & "Forms![frmCalendar]![cmbLineName] = " ' ")
The problem is that the result in tbDate is always 0; regardless of what is chosen in cmbLineName. I know that the record count should not be 0 for all criteria.
