General :: Primary Key Value Not Currently Available?
May 11, 2014
I am under pressure from the client to import data for individuals into the database despite not having their preassigned unique identity number available for every individual. This ID number is the primary key for the table in which individuals' records are stored.
solution that will allow me to import the individuals with a temporarily assigned ID number but that allows that field to be updated with the correct ID number once it becomes available?

why Access requires primary keys to be automatically generated so that there are no redundancies.We have a specific agreement with another organization that involves different billing system in which they send us purchase orders, each with a unique invoice number, that includes orders for one or more events.In my events table I have included a field to manually enter the PO number for this organization when it's needed.
I would like to have another table for the PO's with a one-to-many relationship with the events table (since each PO may cover multiple events). Is it possible to use this manually entered PO number field as a primary key to establish the relationship?

I have an access form which includes my primary key field "ID". Normally when I use this form to enter a new record this field displays "(New)" until I enter data in any other field, then the ID field updates to reflect the new value. This worked fine when the table I was adding the record to was a table linked from another access database.
I recently moved my data to SQL Server 2008, without making any other changes to the application, and this behavior has changed. Now when I enter data into a new record the ID field changes to "NULL". And I am not able to reference this value in my program (Me.ID) like I used to be able to. When I save the record the ID field gets assigned and everything works as normal.
So I am able to make my application work again by forcing the record to save before trying to reference Me.ID, but why the behavior changed when my table moved from Access to SQL Server.

I have an existing database with multiple tables. Two tables have the same primary key Cab#.
1. When user clicks on the form on the menu form, I want to request the Cab# value from the user.
2. Then I want to get the record from the first table CabData based on the entered Cab#.
3. Then I want to create a new record for the second table Rides with five fields from CabData table inserted into the Rides record.
4. Then I want to display the new Rides record to the user for updating.
5. Then I want to save the new record to the RIDES table.
What is the ACCESS termonolgy to do each step? Are there any special details I should watch for?

I would like to define primary key to show in default value "n/=Right(Year(Date());2)"
n - next real number
=Right(Year(Date());2) - equal two last digits from year
The big problem is when we have next year e.g. 2014 real number should count anew.
E.G 6/13, 7/13, 8/13, 9/13, 1/14

How to I combine 2 tables with the same primary key to make one table? I have seen several thigns but none have worked. I seen inner and outer joins. All 4 of my tables have the same primary key. I just want to combine all the tables to make one table. I have a form with subforms but if I can combine all the tables and work off one rather then 4 I will be happier. Every week to 2 weeks I upload new data from excel. How would I after I add the new data combine all tables to one super table?

I've designed a DB in access which has a BackEnd and 2 FrontEnds (one person insert all the records and the others just keep inserting infos till the process is finished.The DB has 12 tables and we used it for about 6 months without having any trouble but recently (2 weeks ago) i've add 3 new tables and then related them to one table that already exist.
The DB was running smoothly for a week after the changes but last monday (09/15) the "Record is deleted" appeared. I've compacted and repaired an the following errors descriptions appeared:
ErrorCode: -1017
ErrorDescription: Record is deleted.
ErrorTable: tblFatura
ErrorCode: -1053
ErrorDescription: Index or primary key cannot contain a Null value.
ErrorTable: tblFatura
ErrorCode: -1630
ErrorDescription: You cannot add or change a record because a related record is required in table 'TblExpense'.
ErrorTable: tblFatura
I've restored the file via IT using the Backup2 days before the error occurred but after 30 minutes the same error appeared! I dont know if it is related to the new tables that i have add or no?

I have an infopath form, which people in my company can fill out to order parts. The form is linked to an Access database. The primary keys for the database are the Order Number and the Line Number (where the specific part info is in the system). The form also takes info about who entered the order, when they entered it, etc.
My problem is that while the form will be used for only one order, it may be used to order multiple parts. So the infopath form has a repeating section with a table where they can enter multiple line numbers and part names, etc.If I use the form to enter just one part, everything works great. But when I use the repeating section to add multiple parts, the information specific to the repeating section is added to the database but the rest of the information (who entered, when the entered, etc) isn't.
My intial idea was that since the first part is entered correctly and the subsequent parts are missing some information which is already in another line in the database. Maybe if there was a way to pull the information from another line into the lines with missing info within access would solve my problem. So basically automatically populating the rows with matching Order Numbers with the information that is missing.

I have created a very simple Access database with a CompaniesTbl, ContactsTbl and CallsTbl. The database is used to record telesales contact with customers. The tables are set up like this:
The CompaniesTbl has an AutoNumber Primary Key field called CompanyID.
The ContactsTbl has an AutoNumber Primary Key field called ContactID and a foreign key called CompanyID.
The CallsTbl has an AutoNumber Primary Key field called CallID and foreign key called ContactID.
The relationships are set up in the relationships window and referential integrity imposed.
Twice now, while editing a contact record, an error has occured. Task Manager has had to be used to get out of it. The error is either a 'run-time error with a message that does not mean anything' or it says 'unrecognized database format' (!?).
If you open the database again the ContactID field in the Contacts Table is no longer a Primary Key field. If you look in the relationships window - the relationship between the Companies and Contacts tables no longer exists.
Any ideas much appreciated.

Hello
I have a problem with a primary key. A table called relaties has a column relatienumber with date type: number, which is also the primary key. When a button is pressed, a function searches info from the table relaties.
The problem is the following: I figured out that when i remove the primary key constraint from the column relatienumber and save the table. the function doesn't work anymore, also when i remake the primary key for this column. How is this possible, because i changed nothing futher.
This is important because i want to change to access db to mssql db and in mssql the function also doesn't work.
It has something to do with this primary key constraint, i think :)
Who has the info???

when defining tables, i normally set an autonumber as a primary key. However, i am working on a particular table, and i would like that no record will have identical values, in three particular fields
aaa bbb 123
aaa ccc 234
ddd fff 555
aaa bbb 123 <- i want to prevent this since a record with those three values already exists
Shall i set these three fields together as a primary key, or can i leave the autonumber as primary key and prevent such duplication in any manner ?
Thank You

Can a PK be a calculated field?
I want to be able create a PK that consists of three strings being added together. The first two would be collected from cascading combo boxes. The third field is a simple text field.
I would then run DLookup to make sure the final string is unique.
I have reasons for not using an autonumber field (there are compatibility issues with existing tables from a much older dbase database).

I have a database that I got up and running but one problem. I have as the primary key a social security number, but I can't seem to be able to add additional information to the same person. All I can seem to do is just replace or edit the one record. Is there a way that I can have more then one order for an individual instead of taking the primary key off of social security numbers?
Do I need a seperate form to enter information because I am currently workin with one form where I can enter and edit the information but no duplicates so lets say if my social was 099-999-9999 I can't add an additional order it seem unl.ess I make a whole new record and make a dummy number...

I have a tblState, every state can have multiple Counties, and every County can have multiple Municipalities
This should be a One to Many to Many, right????
However, several states might have the same County name
In order to resolve this, should I add 2 primary Keys in the tblCounty????
If so, I already tried and couldn’t configure it.
I have attached a sample DB
You can open the relationship view for a better explanation
I appreciate any kind of support
Thank you

Hi all,
Ive written a program in .net and am currently using an access db as the backend.
In the db I had 200 test records which i deleted to get the db ready for deployment. When i add a new record now the primary key on my "booking" table carries on from the old test number so 201.
Can I resest this so it starts back at #1 as once the db gets updated, the program i wrote then takes the data and updates the accounting system and uses the primary key as the invoice number and so I would like to start at 1.
Thanks in advance
Scott

hey guys. i have a field by the name of ISSUE. i am using this afterupdate event procedure
which is as follow:
Private Sub ISSUE_AfterUpdate()
If Not IsNull(ISSUE) Then
ISSUE = Format(ISSUE, "000000")
End If
End Sub
if a user enter like (23) in my ISSUE field my procedure will run and it will replace
the number by (000023) to make it a six digit. i wanted to create a primary key so then a user cannot enter the same number again
or cannot duplicate a record but i cannot because primary key cannot take a null value. Can you all tell me anything to add in my procedure so that once the number is entered like (23)
another user cannot enter (23) again in the record.
Thanks

:eek: I have an order database via Access 2000, the backend became corrupted. I ran a a software program to recover the data. It recovered the data, but the autonumber was changed to just number and it removed primary key setting to the same field. I created a duplicate table, then ran an append query from the old table to the new one. The autonumber works, but I get the following error when I define the Primary Key and try to save...
"The changes you requested to the table were not successful, because they would create duplicate values in the index, primary key or relationship. " I cannot find any duplicates, and there is no relationships. Any suggestions? THANKS in advance for your help. Cathi
