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 & "));"

Hi,
I am new user of access and have encounted a key violation from an append query. I'm trying to update a master mail-out list and am having a key violation that doesn't add some of my records.
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.

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], " & _
[code]...

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.

Hello,
Firstly, I am very much self-taught on access, so there are several gaping holes in my knowledge, and my database structure is probably not wonderful! I have been learning as I go along, so in the initial stages I have built in several problems which I am now discovering!
My db is designed to track suggestions - i have a table where the idea, progress etc is stored [tblIdeasBank]. This contains an 'originator' (person's name) which is linked to a second table, where the names are stored [tblPeople].
Originally I set up tblPeople with the Primary Key as FullName (e.g. Joe Bloggs) (guaranteed to be unique with the small number of people that would be involved), and a second field called InitialLastName (e.g. J Bloggs). It is this second field that is stored in the tblIdeasBank. Data verification came from the user having to select a name from a drop down box, so there is no actual 'relationship' between the tables. (Didn't realise how useful they were at the time!)
The db has been so successful :confused: that it is now going to be rolled out across the company, which gives me two problems. To populate all the names, I need to import them from Excel, where I will have FirstName and LastName. I have now realised that it would be more sensible to just store these, and create InitialLastName where needed. Also, I may well have duplicate names, so I need to create a unique ID, and a proper relationship. (Yes, I know I should have done that in the first place).
So, I have:
tblPeople:
.FullName (Primary Key)
.InitialLastName
tblIdeasBank:
.Originator (stored as InitialLastName)
And I would like:
tblPeople:
.PersonID (Primary Key)
.FirstName
.LastName
tblIdeasBank:
.IdeaID (Primary Key)
.Originator (stored as PersonID)
With a One-Many relationship from PersonID to Originator
Any ideas how I would go about doing this and changing the Originator for each idea from InitialLastName to the relevant PersonID number, without corrupting the data?
I have searched through Google and various groups, but cannot find a useful answer, so any pointers gratefully appreciated!
Thanks,
Nick

My database tracks all of the staff development sessions provided for the past ten years, thus we have thousands of records. Our school district wants all departments to move away from using an employee's Social Security number to a number assigned by the district. Each employee has been assigned a unique six digit number.
In my staff development database, the employees data (Social Security number, campus, job description, etc.) are in a table, "EmployeesTbl", with the primary key being the Social Security Number. Classes data are in a table, "ClassesTbl" with some of the fields being ClassNum (an autonumber), class name, class description, etc., with the ClassNum being the primary key
in this table.
A third table, "AttendTbl", links the two and shows each class (staff development session) each employee has taken. This table has a a foreign key, "SocNum", that links it to the EmployeesTbl, and another foreign key, "ClassNum", that links it to the ClassesTbl.
I have added the EmpNum field to the EmployeesTbl, and all of the the district assigned employees' numbers have been entered. I have also added this field to the AttendTbl. Is there a means of using a query to fill in the employees number in this table. Is so, I'll then change the primary key in the EmployeesTbl to be the employee number and the foreign key in the AttendTbl to be the same. If not, we face the task of having to key in 18,000 records!
Thanks for any help,
R. Sanders

I want my primary key to be
First 3 letters of surname + first 3 letters of forename + DD + YY (Date of birth)
I can use the after update event to update the primary key field but it won't get saved for some reason so have I missed something?

My problem is that I am trying to update a field (called 'Sold' which is a yes/no checkbox column) for a specific record whenever an event is triggered. I have two forms (derived from two tables), one is called frmInventory and the other is called frmSales. In frmSales, I made a combo box called 'cboItemID' that allows the user to select from a list of items from my inventory table. Each selection from the list has 4 properties, the first of which is the 'Item ID' from the inventory table. Lastly, I have a field in both frmSales and frmInventory called 'Sold' as mentioned above. What I want to do is that whenever I check/uncheck the box in the 'Sold' field in frmSales, I want the 'Sold' field in frmInventory to check/uncheck as well, but only in the record with an 'Item ID' that matches the 'Item ID' from the combo box selection. In other words, I want to match the 'Sold' field in frmInventory with the 'Sold' field in frmSales, but for only the record that has the same 'Item ID' primary key as the one I picked from my selection in the combo box from frmSales.
how to reference another table and check whether or not it's 'Item ID' primary key is identical to the one I specified from the combo box, and then take action to update the 'Sold' field if the IDs match.

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

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?

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

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

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

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!

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 our primary web based inventory system that I am exporting to Excel and using this as an import to Access for the main raw data for my database. This being inventory it changes daily so I am updating this table every day. When I try to append the table it ads all the records. I am wanting an easy way to add only the new records/take out the ones that are no longer there. Basically update the table with what is currently there.The only have I have found to do this is by running non-matching queries and update queries.

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?

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

Hi everyone,
Hopefully someone can help me.
In Table 1 - I have a set of contracts that have a unique number. However, although the primary key is the contract number - these numbers can be duplicated as long as their start and end dates don't overlap. So my question is, how do I make the Primary key the contract number plus the start and end date? Is this possible?
I know I can select multiple fields for the primary key, but this has a problem...
Here are 3 examples of how Table 1 could be constructed and the Table outline...
Table 1
Field 1: Contract Number
Field 2: Contract Start
Field 3: Contract End
Field 4: Contract Details
Records
Contract Number/Contract Start/Contract End/Contract Details
001/01-Apr-07/31-May-07/Items Cost £1
001/01-Jun-07/31-Jul-07/Items Cost £2
001/01-May-07/30-Jun-07/Items Cost £1
Now, if I select Contract Number/Contract Start/Contract End as the primary fields, the above would not create any conflicts. However, the third record overlaps the first two records date barriers - and I don't want that to be possible.
Any new record's start date MUST be after any existing record with the same Contract Number's End Date. Also, any new record's end date MUST be before any existing record with the same Contract Number's Start Date.
In Table 2 - I have a list of orders that relate to Table 1. i.e. Each order has a contract it relates to. How do I make sure that in a query, the order number picks up the correct contract for the corresponding date.
For example...
Table 1
Field 1: Contract Number
Field 2: Contract Start
Field 3: Contract End
Field 4: Contract Details
Table 2
Field 1: Order Number
Field 2: Order Date
Field 3: Contract Number
My query would pick up Order Number, Order Date, Contract Number, Contract Details.
I think what I'm looking for is validations in the fields. But I'm not entirely sure how to implement those.
I hope I'm making sense...
Thanks again for any assistance,
Ross

I am trying to run a query that links to tables, orders and invoice together. I am pulling fields from each table, with a relationship between Order# which is found in both tables. The only problem is, order# is a composite key in the order table and strictly a foreign key in the invoice table, referenced through a combo box drop down. When i attempt to create a query, it will not run. (Also will i find a similar problem with my combo box reference?) Any ideas on how to create a query would be appreciated.

Anyone...
Please can you tell me how I run a make table query that makes one of the fields a primary key. Can it be done in the query or do I have to set it as part of a macro that runs the query. If so How do I achieve this.
I am running a make table query from a link table so i can use it with infopath. I run the make table query every time I update the spreadsheet that the link table runs off and it makes a proper table with it for infopath to run off (because I can't get infopath to run off a link table, No primary key means it won't submit.) When I run the macro that runs the query and creates the table, I need it to make oone of the fields a primary key.
Any suggestions
