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!
Jenny

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

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

I am trying to change the standard input mask violation error message to a personalised one. I have found this code:
Private Sub Form_Error(DataErr As Integer, Response As Integer)
Const INPUTMASK_VIOLATION = 2279
If DataErr = INPUTMASK_VIOLATION Then
MsgBox "There was an input mask violation in the field no!!"
Response = acDataErrContinue
End If
End Sub
However, i would like to change the message for a number of different text boxes. and i don't know how to isolate each one, and give each one a different message?

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.

I have two tables, submit and imgdest. Submit is edited by front-end users to load pictures for back-end users who then delete the images when they're done with them. Submit is edited by a form, in the form I've placed a button (Command37) that has code:
Code:
Private Sub Command37_Click()
Call InsertData
MsgBox "Completed", "0", "Completed Backup"
Exit Sub
End Sub
Private Sub InsertData()
[code]....
This code was working for a short while, now anytime it's run I get error 3027 - Cannot update. Database or object is read-only. However, I can open the linked table and manually change information in it with no problems.

I have ODBC linked tables to a DB2 database.When I try to edit the values in some of the tables (open the table in dataview and edit one record) I get a 3021 Error -No current record.On other tables (linked the same way) I don't get this error
If I try the update by running a query on the same table, I get no errors.
The system I have is a german Access 2010 on german WinXP and a connection to DB2 LUW v9.7
Is there any set of settings necessary for ODBC to work with access and vice versa?

I am trying to build a Form that will show an estimate (then eventually will be moved to a project if customer and employee aggree to price and project) in a Form F_Estimates is a M_Customers(Customer_ID) (Based on a Table) and thier info in a Subform. Also is the "projected costs" from parts out of the Parts(Part_ID) (Based on another Table) in a second Subform as a list that I need to calculate $$$ in
(Dang that still sounds evil and definately NOT understandable even after edit... so)
Here's some basic info
Tables
EstimatesandParts - Table
EstimatesandParts_ID : Autonumber
Estimate_ID : Number
Part_ID : Number
Parts - Table
Part_ID : Autonumber
PartNumber : Text (not a number due to some part#s have letters in them)
PartName : Text
Unit Price : Currency
Description : Text
Estimates - Table
Estimate_ID : Autonumber
InvoiceNumber : Text (again can have letters in it)
EstimateDate : Date/Time
EstimateTime : Date/Time
Employee_ID : Number
Customer_ID : Number
ProblemDescription : Memo
Customers - Table
Customer_ID : Autonumber
FirstName : Text
LastName : Text
CompanyName : Text
Address : Text
City : Text
Province_State : Text
Postal_ZIPCode : Text (CDN Postal codes are letter num letter...)
you can see the link table in the EstimatesandParts Table
Now I want to use that link to populate a subform in the F_Estimates form
Forms
SF_Customers - SubForm
(all boxes atm are text boxes on this form till I figure out the Parts section then will use same base for this so I can pick any customer in the database to be the customer for this estimate. Also will have ctrl button for making new customer with customer form and a refresh on Focus Gain bit of code)
FirstName
LastName
CompanyName
Address
City
Province_State
Postal_ZIPCode
SF_Parts - SubForm
Default View -Continuous Forms
(want it to be a list of parts that I can grab prices and descriptions from then in a bit of code to calculate a cost of parts)
Part_ID : Combo Box
Control Source - Part_ID
Row Source Type - Table/Query
Row Source - SELECT Parts.Part_ID, Parts.PartNumber, Parts.PartName, Parts.UnitPrice, Parts.Description FROM Parts ORDER BY Parts.Description;
(Pulls info from the table Parts for input into a list of parts to be used on that project)
PartName : Text Box
UnitPrice : Text Box
(here's where I run into problems due to the fact that the form is not based on the parts table but rather the link table EstimatesandParts so I can't propogate the info to the 2 other text boxes, ps I dont care if they cant be text boxes and have to be linked or some other type I'm not "set" just need to find out how to make it work )
(have tried a couple things to complete this task)
Me.txtPartName = Me.Part_ID.Column(2)
Me.txtUnitPrice = Me.Part_ID.Column(3)
(works AWSOME ... for ONE ROW then propogates the second selection to the first and second and third selection to first second and third and so on ...)
(tried to make control source for the txtPartName to)
=Forms!Parts!Partname
(Doesnt exist .. akkk, cant use ActiveForm either as it doesn't focus on the SubForm but the MainForm ... cry)
F_Estimates - Form
Estimate_ID
InvioceNumber
EstimateDate
EstimateTime
ProblemDescription
(all basic Text Boxes)
Employee_ID
Customer_ID
(Combo Boxes Select Customer and Employee from list of present ones of each)
SF_Customers
SF_Parts
(Both SubForms on the main form)
Now this is an Exerp from my entire Database I like to work on one small problem at a time and I have made this its own little database till I figure out the problem then I will bring the info I learn back into the rest of the database and go from there ...
Hope you can help I have a feeling I will need to make a recordset and go from there but I'm just not able to wrap my head around that for some reason
Thanks in advance for ANY and ALL help that I get from here

I dont use linked tables very often, and when I always seem to run into the same problem.
I have two tables. The pri table has an index key defined as an autoindex, with no duplicates. The sub-table is linked to the pri
table key in a many-to-one relationship. The linked field in the subtable is defined as a long integer non-keyed field.
All is okay, until I attemp to add a SECOND record. At that point I get a 3022 error, stating I cant do something because I am attempting to create a duplicate key.
I would love to fix it, nut I am not sure exactly what the problem is that needs to be fixed. The pri key would not SEEM to be getting duplicated, and the subtable linked field is not keyed. Hmmm, I guess I need a steer here please.

Here is the SQL vew:
Also, I've checked the properties for both tables and they match, also I have "Allow zero length" set to yes.
I'd appreciate any help, thank you in advance.

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?

Hi,
I have an Access 2000 database with some linked tables. When upsizing the database I selected 'Save password and user ID with attached tables'.
Therefore in the Linked Table manager after each table in brackets I have the name of the database to which the tables are linked.
I am now wondering if I want to link the tables to a different database how do I change the database name, which is in brackets after the table name.
If I select a table and select 'prompt for a new location each time' I am getting prompted to select a different DSN. At the moment I don't have a DSN and I don't want to have to set one up.
I imagine that the database name and the user id and password I entered in the upsizing wizard are stored in some configuration box but I don't know where I can access this.
Can anyone point me in the right direction??
Thanks

My tables are sybase linked tables to my Access front end. I get this error whenever i click away from my mainform while my not-null fields (textboxes) have not been entered. So, i would like to put an error message "somewhere" that tells the user to fill in the necessary fields and highlight the necessary textboxes in red, instead of this scary ODBC message
http://img82.imageshack.us/img82/6829/error0el.png :eek: :eek:
When i put my error handling in the afterUpdate or afterInsert Event. I still get the above error msg instead of my msgbox.
Where do i put this message? or should be question be, "what the proper way to handle this intimidating error? :)
Here's my error handling:
On Error GoTo Err_Form_AfterInsert
'do something
Exit_Form_AfterInsert:
Exit Sub
Err_Form_AfterInsert:
MsgBox Err.Description, vbExclamation, "Please enter the Project Name, Project Leader Initials, Main User and Status Code" & Err.Number
Me!Combo67.BackColor = "red"
Me!Combo65.BackColor = "red"
Me![Project Name].BackColor = "red"
Me![Project Leader Initials Combo].BackColor = "red"
Resume Exit_Form_AfterInsert
Thanks in advance for your help :D

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

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 & "));"

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

I have made a program in Access with linked tables from oracle (ODBC).
In access when I'm going to use that tables or when I see the records on the table all the numbers with decimals shows without separators (,).
99,99 looks like 9999.
This is a big problem because I'm working with prices.
I tried to change the NSL_Language in Regedit to:
AMERICAN_AMERICA.WE8ISO8859P1
from:
SPANISH_SPAIN.WE8MSWIN1252
AND it works ONLY in my computer, when I try to fix it and change the language doesn't work, and i don't know why.
PD: In addition, in the other PC's, some characters seems wrong like "�" that looks like a square.

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.

I have created a Asset database using MS Access 2010 & the same was published in SharePoint portal. Post publishing, all the "Query & Forms" are working as excepted but the "Reports" are not working.
The "Reports" is designed with "Group & Sort" option. Post grouping am able to see the "=Sum([Expression])" (i.e. Sum of the Value) value in MS Access Locally but not in SharePoint. Once i published in SharePoint, am getting "#Error" message for all the below expression wherever i have used in my reports design.
Expression Used:
Below expressions are works fine locally & getting #Error in SharePoint.

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!

- 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], " & _

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

I have an MS Access accdb with linked SQL Server 2012 ODBC tables. I am working on a procedure to copy data from local tables to these linked tables (identical schema). I did a simple
Code:
DoCmd.RunSQL "INSERT INTO linkedTable SELECT * FROM localTable"
This works, but is very slow. Way too slow. (INSERT copies the data one record at a time).
I would like to copy the data in a bulk operation, or operations that I can execute programmatically.

I have a table for a multiple parents linked to a child table. I need to figure out a way to only allow 1 parent to be coded as primary, 1 as secondary, and then the rest as other... I thought about making Primary/Secondary/Other a primary key. But then I can only have 1 other. I would have to make a finite number of parents that could be entered and I want an infinite number.... My end goal is to have a report that only has a primary and second parent on it, but the rest of the parents still exist in the table...
*Child_ID
Parent_First_Name
*Primary/Secondary/Other
