No Unique Index Found For Referenced Field Of Primary Table?
Apr 12, 2013
I am trying a to build a slot booking database in which users will be able to book slots (ranging from 1-30) on a particular day for a specific site (location).
When trying to build the relationship between slot in tbl_available and slot in tbl_appointment i get the following error "No unique index found for the referenced field of the primary table" the same error pops up when trying to build a relationship between site in tbl_available and site in tbl_appointment.
I need both relationships to be 1 to many.

I am trying to create a one-to-many relationship between these two tables. I want to be able to access the 3 fields on the [Processors] table within reports based on [AllItems]. [AllItems] is a listing of account activity where the [AccountNumber] repeats. I have every field set as the "Primary Key" on [AllItems] as that is the only way to avoid importing duplicate data. I am getting the error: "no unique index found for the referenced field of the primary table"

Can't figure out why I can't create a one to many relationship between two tables:
TableA uses a composite key as its primery key (field1, field2).
The table has a unique index comprised of these keys. The index even has a name. The table also doesn't contain any duplicate information, so the fields comprising my Primary Key are unique. The table I'm joining tableA is unpopulated at this time.
TableA
FIELD1 FIELD2
99999 ABCDEFG
99999 HIJKLMNO
Any help will be greatly appreciated.

I am building a database to capture monthly statistics on a number of items. I want to ensure that users don't enter statistics for the same item for the same reporting period. I found the following instruction, but can't make it work:
It suggests that I create multiple primary keys in the table
When I do it, it comes back with an error: Index or primary key cannot contain a null value.

To prevent duplicate records, I use multiple fields indexes, which worked fine until now. I learned that each "empty" fields are consider unique by Access, so not the best in an index to prevent duplicate records. I managed to have it worked using the default value property to give each "empty" records the same value.
Now my problem is that I have a date field which is optional, but I need to use it as a unique identifier in an index. I could again use a default value, but since it has to be a date, I find it confusing. I would rather have a default value of "No date specified" or "-" or even better, "". Unfortunately none of those works with date fields.

Any help'd be appreciated. :D

Hi,
I'm not sure where to post this, maybe VBA or Forms would be better, but I think it's fundamentally an index problem, so I'm posting here. I've searched both the net and here, but most of the questions are about preventing duplicate records.
I want to prevent duplicate records but save changes to existing records.
I have a form based on a table that has a 3-field-unique-index (but not the primary index, which is autonumber). I've written a function to check for existing records with the given combination of the three fields, as long as all have data (it bails if any are null). I'm calling the function from BeforeUpdate for each of the textbox controls. I was also calling it from the form's BeforeUpdate, but commented it out as it seemed redundant. I have other code there verifying that the user wants to keep the changes.
I'm trying to save the users from getting all the way to the end before discovering there's a problem. To test it, I added then deleted one character from one of the three relevant fields in an existing record, and bing, up pops my alert that I'm violating the index. Then I can't leave the field, I'm stuck there because I can't save the record.
I want it set up so that other fields in the record can be changed/updated AND so that a new record for the same person can't be entered (a dupe).
Oh, and I'm running into all kinds of problems with acCmdSaveRecord not being available. I feel like an idiot that I haven't been able to make sense of the posts about that. I can just comment it out and let Access save the record when it closes the form. But my bosses really want the users prompted about saving changes.
Any thoughts or suggestions or insights greatly appreciated. I really tried to search this out, so any tips for better searching are also appreciated.
Here's the code for the function:
Public Function CheckForClientDupes()
Dim response As Variant
Dim strFamID, strLName, strFName As String
Dim strFilter As String
If IsNull(Me!FamilyIDNo) Or IsNull(Me!strLastName) Or IsNull(Me!strFirstName) Then
Exit Function
End If
strFilter = "[strFamilyIDNo] = """ & Me!FamilyIDNo & """ And " & "[strLastName] = """ & Me!strLastName & """ And " & "[strFirstName] = """ & Me!strFirstName & """"
If DCount("*", "tblClients", strFilter) > 0 Then
response = MsgBox("There is already a client with this combination of FamilyID, Last and First names in this database. Would you like to Continue Anyway (Yes) or cancel data entry and Erase Your Changes (No)?", vbYesNo, "Duplicate Client Alert")
If response = vbYes Then
' DoCmd.RunCommand acCmdSaveRecord
Else
response = MsgBox("You have chosen to cancel your changes. Your changes will be erased.", vbOKCancel + vbQuestion, "Data Entry Cancelled")
If response = vbOK Then
Me.Undo
Else
Exit Function
End If
End If
End If
' Me.FamilyIDNo.SetFocus
End Function

I am currently trying to insert a record into my database. The fields in my table are RecordID, BillNumber, CongresspersonID, and Vote. RecordID is the primary key and its data type is Autonumber. It says the primary key can't be null, but it's not! It wouldn't let me upload the database because it says it's too big. This is my code:
PrivateSub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.ClickcongressCommand.CommandText = "Insert into votingRecord(BillNumber, CongresspersonID, Vote) Values('" & ComboBox1.Text & "', '" & TextBox1.Text & "', '" & ComboBox2.Text & "')"
Dim numOfRecordsChanged AsInteger = congressCommand.ExecuteNonQuery()
[code]....

Hi - it's been a while since I did much access and am trying to help someone out and have got into a pickle! A quick job has turned out to be a lot more complicated! Plus I'm having to use *spit* Acc 2k.
When I go into frmHighCostDrug (from the "add new drug episode" button on the frmPatient) I often get the message "The changes you requested were not successful because they would create duplicate values in the index, primary key, relationship etc etc."
Now, I didn't think I'd forgotten that much. I've got primary keys, values in the table set to Null, relationships set and ref integrity set and cannot for the life of me see why this is happening.
I know though, that one of you will say "oh it's that" and point it out and I'm going to feel completely stupid, but at the moment, I don't mind! I really can't figure it out.
I've attached db - it's in Acc2k and I tried to do a copy Acc'97 for those who don't have it but it caused no end of problems. Came up with messages that this form contains data that Access doesn't support!!!! ??? :confused: If I can sort it I will.
If anyone's got any ideas, I'd be v grateful!
Tnx
Ally

I have a form with a tab control. On the 2nd tab, I have a subform. This subform is linked to the Primary key of the Mainform. They both use the same query. when this form loads, it goes to a new record. I can update that record and go to the 2nd tab to enter more information for that record, and it works fine, however, if i then go from an existing record to a new record, i can enter all the information on the first tab, but when i go to the 2nd tab, i get Index or Primary key cannot contain null value. If i go back to the first tab, then right back to the 2nd tab, everything works. Why is it doing this?? please help urgent. here's my code:
Tabcontrol On change:
Code:On Error GoTo Err_TabCtl0_ChangeIf IsNull(VerificationNo) ThenElseDoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70Me.RefreshEnd IfExit_TabCtl0_Change:Exit SubErr_TabCtl0_Change:MsgBox Err.DescriptionResume Exit_TabCtl0_ChangeEnd Sub
Create new On Click:
Code:On Error GoTo Err_NewVerification_ClickIf IsNull(VerificationNo) ThenElseDoCmd.GoToRecord , , acNewRecInboundQuestions!lblQ4bExplain.Visible = FalseInboundQuestions!Q4bExplain.Visible = FalseInboundQuestions!Q5Explain.Visible = FalseInboundQuestions!lblQ5Explain.Visible = FalseInboundQuestions!txtQ10.Visible = FalseInboundQuestions!Q10.Visible = FalseInboundQuestions!lblPrevPlan.Visible = FalseInboundQuestions!PrevPlan = FalseInboundQuestions!Page1.SetFocusVerificationNo.SetFocusNewVerification.Enabled = FalseEnd IfExit_NewVerification_Click:Exit SubErr_NewVerification_Click:MsgBox Err.DescriptionResume Exit_NewVerification_ClickEnd Sub
I think maybe what i need is an event on my subform that navigates the record on the subform to the same record that is on my main form. I think my subform is staying on a new record. Please help me ASAP!

I am running up against an error "Index or Primary Key Cannot Contain Null Value". In the dialog box it doesn't give the RTE number just the description, OK & Help buttons. After some searching the description matches RTE 3058.
I have identified why it's happening and through a process of elimination it's happening in the Before Update event of a subform. I have tried to catch it in an error handler so I can have a bespoke dialog box to inform the user exactly why it's happened and then undo, but it just goes straight to the dialog box.
How I can catch this?
Access 2010.

I have a .csv file that I am trying to import via:
External Data > Text File
My Delimiter is a | . My Text Qualifier is a "
I keep getting the error Index Or Primary Key cannot contain a null value.
However, I have manually gone through and removed all Indexes. There is also no primary key defined:
1. Is Access trying to identify a primary key for me?
2. Since I have not defined a primary key how can there be a null value in it?
I have tried to:
1. Add an additional AutoNumber Field (Indexed=True, No Duplicates) but this did not seem to fix the issue.
2. To Not import the fields that I suspect are being categorized as a primary key.

I've inherited a rather messy database which and I need to split it in order for us all to be able to enter data at the same time without problems however I get the following message..Index or primary key cannot contain a Null value..It happens at the table that contains the majority of the data (typical) but I cannot understand what could be causing it. I've check Null Primary Key field and removed all of the "required" statuses out of the fields but still no luck.
I tested on a backup database from a couple of days ago and it worked. Only difference is I've added a few bits and bobs since then and 1 field in the table it's stalling on but this field doesn't contain any null values either and I've tried deleting that field in my test database but made no difference.

This is a real mind bender.
I am running a2k. I am merging two databases. table1 is in the backend database. table2 is linked to the second database.
I run an append query to add table2 entries to table1. The append fails for 96 recs saying key violation. Turns out I can rerun the append if I drop the zip code field.
I then try to manually change the zip code and receive the duplicate values in index, primary key, or relationship.
I ran a compact & repair the databases, still no go. I can't edit the value of the zip code. I import the table to a new database. Still can't change the zip code. I drop MANY of the indexes. Even the index on the zip code field. Run compact&repair. still getting the index message. I even re-imported to a new db again. Still same error message.
I may start again by importing JUST these two tables to a new blank db and see if I get the same issues. I'll keep you posted...but maybe there is someone out there who has seen this error before.
fyi-if I enter a new record, the autonumber field correctly increments to the next available autonumber field. (I say this because of another thread on this matter w/ autonumber fields and bug in A2003)

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?

After a lot of reading and consolidating VBA codes for audit trail.How My Audit Trail Works..A module was made for a function named as "Changes" .Then inserted into before update event of a form where I will do the editing of the records.Then I made a table named as Audit.Inside this table I made all the fields I needed such as:
*AuditRecordId[autonumbered]
*FormName[The name of the form for editing]
*Index[The record ID of the record being edited]
*ControlName[The Field being edited]
*DateChanged[Date change was done]
*TimeChanged[Time change was done]
*PriorInfo[for the old value of data being changed]
*NewInfo[For the new value of data changed]
*CurrentUser[The user base on log in form that was set to Global into another module]
*Reason[The reason for changing for future references]
And Here is the Function Code:
Code:
Option Compare Database
Option Explicit
Function Changes()
Dim db As Database
Dim rs As Recordset
Dim strSQL As String
Dim strCtl As String
Dim strReason As String
[code]....
This audit trail function is valid only for one(1) form, due to the limitation of
Code:
Screen.ActiveForm.Controls("SUP ID").Value
where "SUP ID" is the primary key of the record being updated/Change, so if there are Five(5) tables that needs audit trail, there will be also Five(5) forms, as well as Five(5) Function Changes namely; Changes(), Changes1(),Changes2(),etc... because all the table do have their own sets of primary Key.
Is there a shortcut, in such a way that the "rs!Index" will automatically return a value, equivalent to the Primary Key/Record Id of the record being updated/change, given that there are different updating forms for each table to be updated?

I have a couple of tables which only have a single field. Is it worth adding a second field in order to hold an ID number (is this commonly termed an index number?) for each entry.
My other tables with multiple fields include a field for an ID number and these tables are linked via these fields.
At this stage I cannot see any reason why, in the future, I would want to add additional fields to the tables which I am currently planning to make single field.

I have a situation where I have a report which I will generate to print our companies pricebook. I need an index/table of contents for customers to go to the page where a product is to look up prices. The problem is that we add and subtract products on a consistent basis.
So a new product will get added, but of course, to run alphabetically, there's no way to insert it, then renumber the pages for it to be easily found.to use a maketable query, which sorts all of the products alphabetically. Each time it is run, it will delete the previous table. I then need to have an autonumber field created to create my "page numbers". Yes, each time the pricebook is run, products can and will oftentimes get new page numbers.
So my thought is to have a macro run which creates the autonumber field to the table. This will then be the basis for the form, which will in turn utilize the "page number"/autonumber field to both serve as page numbers in the report. And of course, the table which is created each time will be the "table of contents".

OK, Here is my issue:
CustomerTable:
PK:CustomerName
AgreementTable
PK:[Lookup]CustomerName from Customer Table:Agreement#
AddendumTable
PK:[Lookup] Customer Name:Agreement# from Agreement Table
So, Each customer may have more than one agreement.
Each agreement may have more than one addendum.
So when I create a table to create a new addendum, naturally I would like to link this to an agreement (which has already been linked to a customer). When I do the lookup wizard for the agreement field however, instead of being returned a list of customers, i get the PK of the customer and not the customer name.
How do I get the lookup to show the customer name and not the PK.

use the same referenced ID more than once in the same table? I have a database for my stamps. The exact same type of stamp may be kept in more than one location (Album). So, I have TBL_Albums which has two fields "AlbumID" and "AlbumName". Can I use "AlbumID" in my main RecordSource "TBL_Main" more than once to reflect the different Albums this stamp may be found in without causing any major problems to the database?
If this is okay, I could then assign different alias names to each "AlbumID" column in "TBL_Main" such as Location1, Location2 etc to be able to tell them apart on forms etc.

I have a database in Excel that contains farmers who can be identified by a Unique identifier: MZ-01-0001. The registration details for these farmers are not always up to date. Now when I try to append the data for the farmer with MZ-01-0001; with the primary key set on the Unique identifier, Access does not want to do it since there is already a record in the system. When I remove the primary key it doubles the record, which is also not what I want. So I am wondering what I need to do to append the record while keeping the primary key intact.

I have a form with two tables referenced. I am using the form only to update one of the tables. I am using the other table to pull a reference field. When I add my second table using the query builder, it makes it to where I can't edit/add in my form. I assume its because of the SQL insert statement, but I don't see this statement and can't find where it is to edit it. How to have the form only update one of the tables, while just using the second table as a reference for a field?
