Find Duplicate PrimaryKey Violation...

Oct 24, 2006

Okay,

I have 33,099 records in a query, that i'm importing into a table. (don't bother witht he semantics, it's from a linked dbf file)
The table does not have a primary key. Given Three Fields (out of 74):

Item_ID
Title
AltTitle

With the table populated with all the records, I highlighted those three fields in Design View of the table, and told told access to make all three of them the Primary key. Upon attempting to save the table, I got an error message saying that data in the table violated the primary key unique fields rule or what not.
So I wanted to make a query to determine where the error occurred. I could not off the top of my head figure out how to select only the duplicated records in a table, so instead, i figured if they violated the Primary Key unique field rule, there should be duplicate entries. so I did this:

select distinctrow item_id, title, alttitle from tbl_Table;

I got 33, 099 records returned on the DISTINCTROW. Strange as that was, I deleted all the records from the table, set the primary key as I wanted it, and then repopulated the table via my sql insert into commands. This time the table reports only 33,093 records, meaning 6 records somehow violate the primary key unique index, but don't violate a DISTINCTROW call. How can i find them to determine how they are violating the primary key unique index?
thanks

Modules & VBA :: Index Or Duplicate Key Violation

Apr 1, 2015

I am trying to add a "T" in front of an article number and write this new number to a table.Access cannot find the new Article strArt because it does not exist. When I put a msgbox after "if .nomatch then" it correctly shows the message. Yet it refuses to create the new record because of a key/index violation. Apart from an index on the recordkey, it has an index on Artno, both indexes do not (obviously) want duplicate values.

Here is the code:
Private Sub btnCopyT_Click()
Dim db As Database
Dim rstArt As Recordset
Dim strArt As String
Set db = CurrentDb
strArt = "T" & Me.frmNomenclatuurSubfrm.Form.Artno

Index Called PrimaryKey

Mar 6, 2006

Hi,
To make a long and tedious story short:
Does anyone know why Access (2003) creates an index called PrimaryKey and an index called User_ID when I'm in the table design view and ask it to make the User_ID field the primary key?

After years of database development I've only just noticed this. Not normally not a problem but for this:
Use ADOX to find the field name of the primay key for a table. I took the code right out of a Access 2000 developers handbook. It creates a collection of the table indexes and steps through them one at a time checking if the PrimaryKey property is true. It hits the index called PrimaryKey and says 'yes it's true, this is the PK', I then go on to use the index.name property in an SQL Select to create an ADO recordset. The only thing is that the index called PrimaryKey is not a field name and the field name User_ID is not a PK :eek:
I go into the indexes list in table design and delete and re-create the indexes and PKs as I want and the code works fine.

So, again, why does Access do this? I'm so confused! :confused:

Find Records With A Duplicate Field Entry

Jul 24, 2007

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.

Comparing 2 Tables To Find Duplicate Values

May 9, 2006

Hey all

Im rather new to access but have to use it at work. Ive been asked to see if there is a way to delete duplicate records from a table.

Now, I have 2 tables. The 1st table (tbl_list) contains records of various customer details. This list is old.

The second table (tbl_new_list) contains new customer details.

We have found that we have the same customer details in tbl_new_list that are in the old table.

Im looking for a way to compare these 2 tables so that the values in tbl_list are not in tbl_new_list.

I have tried numerous methods using append queries but nothing seems to work.

Thanks in advance people

P.S the data will be compared through a telephone number.

If Primarykey Value Exists, Bring Up Record

May 9, 2007

Hello

I am trying to figure out how to make my database check to see if the primary key value is a duplicate of anything ive entered previously and if yes, for my database to bring up that record instead of adding a new record.

I know how to do bring up records using a separate combobox (find) but I cant seem to do it using the primary key field itself.

Many thanks in advance.

Says Primarykey Is NULL When Infact Isnt

Mar 25, 2008

hey again, i usually don't post this much and prefer to work it out alone but i have no idea why this isnt working (and the error im getting)

below are screen shots, i am trying to make an improved booking system, but i don't know why its saying i have a null value (i went through and made sure all fields are filled, in all related tables just to make sure)

http://i71.photobucket.com/albums/i136/King-b-/QueryPrimarykey.jpg
http://i71.photobucket.com/albums/i136/King-b-/QueryPrimarykeydesign.jpg

Is your BookingID set to autonumber? If it is an autonumber, where does the B come from?

no i have them all set as text with a inputmask of B000 (so booking numbers have to start with a letter (b) followed by three numbers)


(i edited and made new post as had a vague, uninteresting title)

Modules & VBA :: Afterupdate To Find And Goto Duplicate Values

Apr 10, 2015

Someone fills in a new patient into the database, and the 'chipsoftnummer' which is the number in another database. That number is unique, so i want to have it where if someone fills in a number that already exists in the database the afterupdate event will open that record in the form.Here's the code i put in the input textbox update field:

private Sub chipsoftnummer_AfterUpdate()
Dim NewCHIP As Integer
Dim stLinkCriteria As Integer
Dim custNo As Integer

[code]...

It doesn't work, simple things like hello world do work so VBA is enabled.

I've attached the corresponding part of the database (took out all non-relevant fields and tabs) .

How To Find Duplicate Entries Across 2 Columns In Access And Line Them Up

Nov 16, 2012

There is an issue that I cannot resolve in MS Access:

I have a large files with multiple columns that has 2 columns that randomly contain duplicated data.

I would like to filter out the duplicated entries in these 2 columns without spoiling the data integrity - and so the duplicates appear on the same row.

I think what I want it pretty much like conditional formatting in excel, but unfortunately the file size is really large to be filtered in excel.

Key Violation Error

Mar 17, 2008

Hello I am new to this forum. I am trying to use the append query on two tables that are identical in data type, from TblA to TblB, but cannot append due to key violations for each row.

Both TblA and TablB have an autonumber primary key, although TblA does not need to have a primary key. Any suggestions as to what I should be looking for first?

Thanks

Trying To Append Rows With VBA - Get Key Violation

Mar 9, 2008

Hey all. I'm trying to append rows to my database with some VBA code.

The code looks like this:
vInsertLoanSQL = "INSERT INTO Loan(BookID, MemberID, StaffID, BorrowingDate, ReturnDate) VALUES (" & vBook & "," & vMember & "," & vStaff & ", #" & Format(Date, "dd/mm/yyyy") & "# , #" & Format(vDueDate, "dd/mm/yyyy") & "#)"

DoCmd.RunSQL(vInsertLoanSQL)


The variables are all filled out.

The table that it's being inserted into, Loan, has an Autonumber primary key (not included in the INSERT script) and a number of other fields that have no zero-length restrictions, no "Required" fields set to Yes and no Indexes. The table in question is also completely empty, there are no rows (they have all been deleted) - so I have no idea why I'm getting that "Microsoft can't append all the rows in the append query" error. It says its a key violation but I really can't see how its possible.

Anyone out there know whats going on?

Yet Another Append Key Violation Error....

Mar 30, 2008

Wow, this thing is annoying me. I give up! I've attached the database for anyone here to have a look at. I promise there's no nasty code on it, although you should be able to see my code and hopefully pick the problem if you disable macros anyway.

I use VBA to prompt users to enter their staff number, the member's number and the book ID. The same VBA checks to make sure that it's a valid number that they're entering, that's it's actually present in the table it's being referenced from. (Command0 button. Command1 is to return an item)

It then takes these values, the current date and another date variable and inserts into the LOAN table. The loan table has enforced referential relationships with the book, member and staff tables.

The insert code is:
vInsertLoanSQL = "INSERT INTO Loan(BookID, MemberID, StaffID, BorrowingDate, ReturnDate) VALUES (" & vBook & ", " & vMember & ", " & vStaff & ", #" & Format(Date, "Short Date") & "#, #" & Format(vDueDate, "dd/mm/yyyy") & "#)"

All the fields in Loan (except for the autonumber PK) are not required, and have no validation formulas, zero-length is permitted where applicable.

I KNOW that the numbers being inserted are in the related tables! They're the same data type - long integers, and the related tables' primary keys are not autonumbers.

So why am I still getting a key constraint violation??

Can someone please help me??

Correction: I'm trying to attach the database, but it's too big, even zipped. Why isn't RAR accepted? Anyway, the file is hosted here: http://jellopy.com/files/newdb.zip

Primary Key Violation In Update Query

Apr 21, 2006

Hey, I am getting a primary key violation when I try to run an update query.

My primary key is a combination of two fields, ScheduleID and SchedulePage. That way for each schedule I can only have one Page 1, one Page 2, etc.


When I want to insert a page (say a new Page 2), I need to update the table so that Page 2 becomes Page 3, Page 3 becomes Page 4, and so on.

The problem is, since it starts at the bottom, when I tell it to increase the page number by one, it's conflicting with the primary key of the next record.

Any ideas? BTW, if the solution has to do with sorting, I need to make sure it's something that always defaults back to the correct sort, since users may be able to change the sort and accidentally save it. Plus, I'll need to do the same thing in reverse (delete a page).

DoCmd.RunSQL "UPDATE Pages " & _
"SET Pages.SchedulePage = [SchedulePage]+1 " & _
"WHERE (((Pages.ScheduleID)= " & varScheduleID & ") AND ((Pages.SchedulePage)>" & varSchedulePage & "));"

Linked Table Creaes Key Violation Error

May 23, 2005

Hi, I have a form that consists several buttons. One is to delete a table A, then add records to several tables and eventually it will do a join and insert records to table A, and display a report. It always works while all tables reside in the same Access database. Now we are trying to migrate to SQL server but not ready to get rid of Access yet. So we exported all tables to SQL server and created linked tables. We can open tables directly from Access without any problem. It shows the contents as the SQL database But when we tried to open the form and run the same button as before, we got an error:

Microsoft Access can't delete 0 record(s) in the delete query due to key violations and n record(s) due to lock violations.

We have no idea why this happens. Most of the time, it worked the first time when we clicked on the button. But we got the message when we clicked on the same button the second time. If we clicked "Yes" then it will append new records. There will be duplicate records since it doesn't delete the existing ones.

Did any of you encounter a similar problem before? Thanks in advance!

General :: Key Value Violation With Macro Append From Spreadsheet

Mar 10, 2015

I am having problems with an append from a spreadsheet into a pre-populated table. I am using a macro to do this.

The table is in the middle of a hierarchy of tables. For example:

table 1 - Audit - key: AuditNumber & AuditName
table 2 - Process - key: AuditNumber & AuditName & ProcessRef
table 3 - Risk - key: AuditNumber & AuditName & ProcessRef & RiskRef
table 4 - Controls - key: AuditNumber & AuditName & ProcessRef & RiskRef & ControlRef
table 5 - Control tests - key: AuditNumber & AuditName & ProcessRef & RiskRef & ControlRef & TestRef

The front end of the database has a form for each table. Once you create an Audit in table 1 you can create multiple Processes underneath this one audit. Underneath a process you can create multiple Risks...... hence a hierarchy.

I am trying to append data to table 4 - controls. I have copied the format exactly into excel. I have also prepopulated the Audit, Process and Risk data in the required tables.

The reason I want this functionality is to enable team members to populate control information (oftentimes up to 25) in excel and then upload them easily into the database.

The macro I have created will work when created a new table. but when I point it at the existing table 4 - Controls I get the Key value violation error.

Append Query Key Violation (as Used In Create Similar Record)

Oct 18, 2007

I have a database of Assessments, each record having multiple subforms.

I am working on a button, which creates a "similar" (same) assessment, copying over all the subform records/selections.

So, after I actually insert a new assessment, pasting all the values from the original Assessment:

DoCmd.RunCommand acCmdSelectRecord
DoCmd.RunCommand acCmdSaveRecord
DoCmd.RunCommand acCmdCopy
DoCmd.RunCommand acCmdPasteAppend

I need to copy over subform contents, for which I use an Append Query (actually, I use its SQL in VBA code to pass it the right parameters).

Now, naturally, I ran into Key Violations, because taking 50 sub-records from the original they would have their own AutoNumber Keys (ID's) and I can't append them into the same table.

My question: how do I copy over the same records (appending FROM and TO the same table) but cause the table to insert AutoNumbers for the records being appended?

Thanks!

Queries :: Append Query / Adds Records - Despite Key Violation?

Dec 3, 2013

- I have a module which runs queries on linked sales spreadsheets, to merge them in to one Access table.
- To prevent duplication of sales, the primary key merges the sales record and item number fields.

Today, it's found 103 key duplication errors, which is fine. But it's still adding data to the table. The data seems to be fields which aren't even mentioned in the query. It only does this when the query is ran from VBA.

Code:
MergeEbay = "INSERT INTO tblSales ( SalesRecord, SKU, PostCode, Shipping, Quantity, SalePrice, SalesRecordSKU, DateAdded )" & _
"SELECT exEbaySales.[Sales record number], IIf(exEbaySales.[Custom label] Is Null,'0',exEbaySales.[Custom label]), exEbaySales.[Buyer postcode], " & _

Queries :: Insert Into Query Will Only Work On Some Records - Key Violation Error

Oct 23, 2014

I am building an access database for my college project and I essentially have a quotation form that when I click a button 'Convert to Invoice' it creates a new record in the invoice table and then creates new records in the invoice details table which match the quotation details table. This is working as it should but for only the first 2 customers in my customer table?

On the quote form I have a combo box which is linked to the customer table and updates the quote table based on the selection. If I select customer 1 or 2 and click 'convert to invoice' it works and opens an invoice form based on the inserted data however if I select any other customer it returns an error that the record wasn't added to the table due to key violations?

As far as I can tell I am not trying to update the primary keys in the Invoice Table or the Invoice Details Tables.

Queries :: Append - No Records Are Being Imported / Validation Rules Violation

Jan 15, 2014

No records are being imported. I am getting a validation rule violation but I don't have any rules. The forename and surname are straightforward text boxes and the ID is an autonumber.

Code:

INSERT INTO table_candidate ( Cand_ID, Cand_forename, Cand_surname )
SELECT candidates.Cand_ID, candidates.Cand_forename, candidates.Cand_surname
FROM candidates;

1. Is your append query trying to assign values to the primary key field? Could that be the source of the duplicate?

Yes but there are no duplicates

2. Do you have any other fields that are "Indexed: No Duplicates"? Any compound indexes?

No

3. Is the query assigning values to a field that is a foreign key to another table? Is it possible that these values do not match the values in that other table?

No. All child tables are empty.

4. Is there a validation rule on the table itself?

What this means.

5. Does the query attempt to assign a string with no characters in it (as opposed to a Null value) to a text field that has its Allow Zero Length property set to No?

Both fields are text and all records contain information

Required = No
Zero length = Yes

6. Is there a Default Value in one of the fields that is NOT being assigned by the query? For example, a foreign key with zero as the Default Value?

No

7. Is there data that is outside the range a field can accept, e.g. an integer larger than 32767, or a Null to a Yes/No field?

The length of the text in each record is not greater than the set limit

8. Is one of the query fields arriving in a format that Access is not understanding, e.g. for a date, or for a currency?

No

Forms :: Prevent Duplicate Values With Alert After User Enters Duplicate Value

Dec 30, 2013

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")
