Duplicate Record Problem
Jul 13, 2007
The access table has one primary key StudentID which is indexed with no duplicates. (StudentID consists of schoool ID + an auto increment #)
When a second student is entered with the same name and birthdate into the table but with a different studentid the record cannot be saved as there is a duplicate value. If the birthdate is removed the record can be saved. If another character is entered after the first name with the birthdate the record can be saved.
I have tried adding time to the record, that did not solve it. I tried changing name and birthdate to index yes duplicates okay that did not solve it.
The only relationship is on studentid, I cannot understand why the birthdate is the problem when there is no relationship or primary key on that value.
Has anyone experienced this issue and can explain why access views this as a duplicate record when in fact it is not!
Thanks

I have a database with a table that uses a numeric field as a PK. If I use the built in "Duplicate" Command button on a form it creates an exact duplicate of the record, which then Access won't allow because the PK is no longer unique.
Does anyone know of a way that I could make the number be the max number + 1 when I click the "Duplicate" Button?
Thanks

I'm trying to make a simple DB that we can enter our time for working on projects.
So far I have a Form with the employees name and the date in it. Then below that is a subform with the project number, name, client name, and hours.
I want to use this whole "sheet" for one days worth of work for 1 employee. New sheets will be used for each day.
When I try to make a new sheet I get an error that it cant change the table because it would be creating a duplicate entry.
How do I solve this?
Also, should it be difficult to be doing what I'm trying to do?

hi everyone,
i have a form that i'm trying to create a button to duplicate the record. i'm using the control wizard which produces the following code:
Private Sub DuplicateRecord_Click()
On Error GoTo Err_DuplicateRecord_Click
DoCmd.DoMenuItem acFormBar, acEditMenu, 8, , acMenuVer70
DoCmd.DoMenuItem acFormBar, acEditMenu, 2, , acMenuVer70
DoCmd.DoMenuItem acFormBar, acEditMenu, 5, , acMenuVer70
Exit_DuplicateRecord_Click:
Exit Sub
Err_DuplicateRecord_Click:
MsgBox Err.Description
Resume Exit_DuplicateRecord_Click
End Sub
When i try to execute the code via a comand button, i get an error and the duplicate record operation does not occur. one thing i noticed is that i have a lot of lookup fields (i.e. FK's to lookup tables one-to-many relationships) in underlying table being populated by the form. i've created combo boxes on the form to populate the FK's in the underlying table. the error that occurs when trying to use the above code produces a "paste errors" table and in that paste errors table instead of the bound column values from the combo boxes (i.e. PK values from the lookup tables) it shows the display values from the combo boxes. i'm not sure if this has do with anything, but i couldn't figure out why it was doing this.
does anyone have any ideas how i could get this duplicate record procedure to work?
many thanks for any help or suggestions.

After some time, i need to fill another record (new one), with similar values.Is it possible to make a duplicate of my previous record, and put it in the "new record" so that i won't have to fill all fields again, only change excisting ones to different values.
Thanks

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 a search form passing text from unbound controls to a query. These two fields (AuthorName & Title) of the query are from two different tables (Authors & Papers) set up in a many to many join. The 3 dummy records I am using are as follows:
Record 1
AuthorName: Smith (Author 1)
Title: SmithTitle
Record 2
AuthorName: Smith (Author 1)
AuthorName: Jones (Author 2)
Title:SmithJonesTitle
(i.e. two authors for this record)
Record 3
Author: Jones (Author 2)
Title: JonesTitle
If I stick in 'Jones' into the Author field and 'JonesTitle' in the Title field I correctly get 1 result from the query (record 3). However, oddly, if I put in Smith and SmithTitle I get two records (2 x record 1)!!!!! There aren't two records!!! Similarly if I leave both blank I get all the records and again there is a duplicate of the Smith record (and only this one is duplicated!)
The query criteria are:
[AuthorName] Like [Forms].[Search]![Author] & "*"
[Title] Like [Forms].[Search]![Title] & "*"
Any ideas???
Thanks

Hello Forum,
I have a problem with duplicate records in my query. I know why the duplicate records are occuring and I have spent a ridiculous amount of time trying to fix the problem, but I'm really at a lost and am quite desperate for some help.
Here's some background info that shows the cause of the problem:
I have two tables. In the first table (tblMainData), there are three columns of interest (P1, P2, & P3). The second table (tblGroupList) has two columns (PN & GroupList). A relationship exists such that the data in "PN" is parital-text values of the data in columns "P1", "P2" and "P3".
For example, "P1" in tblMainData may contain "A1235XX". The "A1235" is what's important, so that's one of the values that I have in "PN".
Continuing, I have a user form that uses the "GroupList" field as the RowSource for one of my combo boxes (cboGroup), and this field contains an (ALL) option. So, when a value is selected from cboGroup, I use the following Criteria filter
Like [PN] & "*"
in my query (qryFilterGroup) to look for those partial text fields that match what's in fields P1, P2 and P3. The results are then shown in a subform.
Here-in, I believe, lies the source of the duplicate records. In my userform, if "(ALL)" is selected under the cboGroup combo box, a new record is created for each field P1, P2 and P3 in tblMainData that contains data and that is related to the partial text matching Criteria. A new field is created because each field corresponds to one of the values in the "GroupList" field.
This is really difficult to explain, and I don't really know if I should continue without writing a book. If someone or someone(s) could be so kind, please have a quick look at my attached database as it's obvious to see my problem. Any help is greatly appreciated!!

I have a subform that collects the following data to put in a record in tblClass:
StudentID, Trimester, SubcatID, WorkGrade, SkillGrade
Before the record is written for the first time OR edited/updated to the table, I want to search tblClass and determine if the new/updated info will create a duplicate record.
In this specific case, a duplicate record will be defiened by a record where the only fields being considered would be StudentID, Trimester and SubcatID. The fields WorkGrade and SkillGrade should not be considered.
The code I came up with was the following and it was put in the BeforeUpdate:
Dim conn As ADODB.Connection 'Connection Object
Dim rst As ADODB.Recordset 'Recordset Object
Dim strSQL As String 'SQL statement for open statement
' Create object variables
Set conn = CurrentProject.Connection
Set rst = New ADODB.Recordset
' Create sql to search for records in tblClass that match
'studentID, Trimester, and Subcatagory in the form record being added
strSQL = "SELECT * " & _
"FROM tblClass" & _
"WHERE fldStudentID = " & StudentID & " AND " & _
"fldTrimester = '" & Trimester & "' AND " & _
"fldSubcatID = " & SubCatID & ";"
' Open recordset
rst.Open strSQL, conn, adOpenKeyset, adLockOptimistic
If rst.RecordCount >= 1 Then
' record already exists in tblClass
msgbox "Record already exists!",, "Duplicate Record Error"
Me.cboSubcatID.SetFocus
Cancel = True
End If
' Close and disassociate object variables
rst.Close
conn.Close
Set conn = Nothing
Set rst = Nothing
This code worked great except when I went to edit an existing record. When I went to change a grade (WorkGrade or SkillGrade) on an existing record, it told me that I could not enter the record because the record already existed (ie, the record I had open and was editing). I am not sure if it is my code that I need to edit or if it is the placement of the code I need to change.
Any suggestions would be great.

I have a document database that often deals with multiple copies of a document. Each copy must have a record of its own. With the add new record form I would like the user to be able to add the extra copies automatically by duplicating the first entry "n" times but also incrementing the copy number field by one for each copy. Got the duplicate copy done OK but am stuck on how to increment the copy number. This database forms part of my yearly assessment and is due in a couple of weeks so would welcome some help.
many thanks

Hi all,
I created a form for entering employee skillset in Accounting.
I have set up three fields - one for Primary Skillset and the other two for secondary skill sets -
The skillsets are -Payables, Receivables, General Ledger, Purchasing etc.
How can I ensure that a user will not enter duplicate values in the three fields.
That is a user will not enter for examply "Payables" in the Primary Skillset, and Secondary Skillset fields.
I tried creating a multiple field index but it does ont appear to work.
I will appreciate all the help.
Thanks

Hi all,
This is an intersting question that my friend ask me... hope someone can help to solve it.

Do someone have a good idea to filter the combo box when detect a duplicate data and just showing one of each company only? or can i create a query with just listing one of each company from the table with all those duplicate company data?
Thank you.

I want to be able to copy, or duplicate a record including all the associated records of the subform. The structure is the typical, ORDERS, ORDER DETAIL, PRODUCTS. I want to be able to copy a specific ORDER and generate a new one with all associates products. It would be nice to change one field (ORDER NAME), changing the ORDER name would simulate the "Save As.." command.
The end result would be a new Order identical to the first one (including all sub items) but with a different name.
Any suggestions?

I ran into a weird task, sometimes at my job we have to use 3 identicle records where just one thing changes and that is the date. The thing that is giving me a problem is I get an error if I try to duplicate the record due to primary key being duplicated. I have a ID field which gives all records a number and when I try to duplicate the record I am in, I get an error because of the duplication of the ID Field. Is there a way to get around this?

I have a form based on a query and have written code to display a msgbox if a duplicate entry is inputted in the NHS_Number field in the form. I have also added code "me.undo" to clear the form so that it is not saved. I am looking for a piece of code that will display the duplicate record. Here is my code thus far:
Private Sub NHs_Number_BeforeUpdate(Cancel As Integer)
Dim dbs As Database
Dim rst As DAO.Recordset
Dim x As Integer

I am having an issue with one person having trouble getting an error when trying to duplicate a record.
The subform is set up with a button to duplicate a record. This allows most of the data that stays the same to be copied to a new records and then minor changes can be made to update the record for the new month. Since there are memo fields, in these records, this saves a lot of retyping. One person who is using the database gets the following error when clicking on the duplicate record button.
The command or action 'Copy' isn't available now.
It makes a new blank record but won't copy over the information. You can go to the record and copy each field individually and paste it into the new record, but this is not very practical.
I have not been able to duplicate the error and no one else using the database is having this happen.

My situation:
I have a table with duplicate ids. When I have a forum popup another form, the forms are linked by ids. This works great except for one problem. There are duplicate ids. So if I pop up a form then it will go to the first record that that id exist. This is not good if you are going to add another record. Therefore, I need to create a unique variable for a record. The autonumber would be a great variable but it seems I cannot use it to filter. Unless someone can show me how. Is there another way to create a unique variable automatically for a new record?

I have a question on hiding duplication record using query.
The fields in the query are:
full name(trainee), NRIC(trainee), gender(trainee), preferred language(trainee), company(trainee), course name(course), course date(course), competent(course), class(course), L3 survey(trainee), L4 survey(trainee), num of month(course)
When the query is being run, it will show all the people that have not done the L3 and L4 survey after 3 month. The the query will be convert into a form. However the problem is that the record will show a few same name due to one person can take more than 1 course. therefore, the data in the course table will always be different.
How can i make the record only show 1 name even though they have different course name.
I had tried putting 'yes' for unique record and unique value but it did not change the result.
current SQL query:
SELECT DISTINCT trainee.[Full Name], trainee.NRIC, trainee.Gender, trainee.[Preferred Language], trainee.Company, course.[Course Name], course.[Course Date], course.Competent, course.Class, trainee.[L3 survey], trainee.[L4 survey], DateDiff('m',[Course Date],Date()) AS [Num of Month]
FROM trainee INNER JOIN course ON trainee.NRIC = course.NRIC
WHERE (((course.Competent)="c") AND ((trainee.[L3 survey])=False) AND ((DateDiff('m',[Course Date],Date()))>=3)) OR (((trainee.[L4 survey])=False) AND ((DateDiff('m',[Course Date],Date()))>=6));

I am working on a SKU generator and I need to prevent duplicate SKUs, but each SKU is made from several different fields. i.e. Brand, Color, Design, etc.
I was wondering if Concatenating would be OK for this situation. I know concatenating usually results in redundant data and I try to avoid that.
I would like to just index (no duplicates) the entire record... is this possible? I can't just set that attribute to each field because there will be many duplicates on a per field basis. i.e. Brand will be duplicated every time I use the same vendor for a different shirt.
I can't just go back and address duplicates once they occur. I need to prevent them from occurring in the first place.

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.
