Duplicate Values In Index, Primary Key Etc
Feb 27, 2006Hi - 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

Finding Duplicate Values From The Table Having No Primary Key
May 18, 2005Hi All,
I have one table where ID field is autogenerated, and another field orderno which is not primary key. Now it has 2 duplicate values in it so when I try to make field Orderno as primary key, it is not allowing me to do so.
Can any one help me how to find the duplicate values using query.
Thanks in advance,

Changes Not Successful; Create Duplicate Values In The Index, Primary Key, Or ...
Nov 29, 2005This 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)
Forms :: Prevent Duplicate Values With Alert After User Enters Duplicate Value
Dec 30, 2013We 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")
Avoiding Duplicate Records Without Using Primary Key
Sep 21, 2015I have a modest sized data base and have been having trouble keeping out duplicate records with the same last name, first name, and DOB. I know I could use all 3 fields as a primary key, but I would like a simpler way of checking for duplicates.

View 4 Replies View RelatedQueries :: Query Records With Both Duplicate Values And Different Values?
Jun 18, 2013I'm trying to determine the SQL to return only those records in a table which have duplicate values in each of two fields, but different values in a third field. Here's an example:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A123 Apple Fruit
A123 Apple Fruit
A123 Grape Fruit
A456 Potato Vegetable
A456 Potato Perishable
A789 Carrot Vegetable
A001 Banana Fruit
For the above table, I'm trying to return records which have multiple entries for AcctNum + FoodType, but DIFFERENT values for FoodClass. So for the above table, the query would return:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A456 Potato Vegetable
A456 Potato Perishable
It returns these two records because there is more than one record with for the AcctNum + FoodType (i.e. 'A456' + 'Potato'), but DIFFERENT values for FoodClass (i.e. one record has 'Vegetable' while the other has 'Perishable').
Tables :: Limiting Values To Match Primary Key
Aug 29, 2013I have a very basic three table structure.
Clients
ClientID (PK)
ClientName
Boats
BoatReg (pk)
ClientID (FK)
Description
Quotes
QuoteID (Pk)
ClientID (fk)
BoatReg (fk)
What I would like to do is for the BoatReg field in the Quotes Table to only display the boats that have been registered to the Client that has been selected, currently it displays all the BoatRegs.
Create Primary Key From Values Entered In The Field
Nov 28, 2014I have two Tables, Table A and Table B...Table A and B have a one to many relationship with A (one) and B (many).I have a Master form that displays information for Table A. Also, I have a subform within this Master that displays information for Table B.
As I scroll through the records of A, you can see the 1-many relationship elucidated in the subform with many being displayed for Table B.I run into a dilemma, though, when I try to ADD a new record to Table A (and in turn Table B).When I add a new record, there is no Primary Key left to be displayed since this primary key is generated from a query.Hence, when I move to a new record, I can not save the record because there is no primary key. Since there is no primary key, there is nothing that i can input into the subform either. I want to create the primary key from values entered in the field. However, i CAN NOT create a relationship with an expression for field values.
Duplicate Values
Apr 19, 2005I have a many to many relationship, and one of my tables (the junction table) has only 2 fields (BookID & AuthorID). These fields together are set as primary key, in order to avoid duplicate records. Eventually, if i will try to put a duplicate record, i will get Access error's message "The changes you requested to the table were not successful because they would create duplicate values in the index, primarykey or relationship ..."
What is the best approach in order to check whether a duplicate record is going to be created, and if yes, i will get a customised error message rather than the above mentioned default error message ?
Thanks
Duplicate Values (Please Help)
May 18, 2006I need help creating a report that summarizes duplicated values.
I need to write a query that groups payments of equal amounts (duplicate values only) for each vendor together. I need to show a group header containing the vendor number and name.
I was using the Having Count(*) > 1 function but that only tells me which values are duplicates It doesn't display them. I need to display the duplicates.

Allow Duplicate Values!
Apr 26, 2006i have a sub form which on the click of a button sets 4 fields
Private Sub Command8_Click()
LastPaymentDate.Value = Date
NextPaymentDate.Value = Date + 7
AmountPaid.Value = [Form_Frm_Customer]![Payments]
[Form_Frm_Customer]![Payments Due By].Value = Date + 7

It updates all the fields fine but i keep getting the error 'the changes you requested were not successful because they would create duplicate values'
I have checked the table and all fields are set to allow duplicates.
Cant figure it out.
Tables :: Setting Primary Keys To More Than One Field In Table / But They Cannot Have Null Values
Nov 30, 2012Access 2010..One organization that we work with provides us with a block of numbers for each of the two types of contract products we order from them; we do order non-contract stuff from them also.The block of numbers are the same (i.e. 20000 to 30000 this year) for each of the two products. This means that each product can have the number 20000, for example. We call this the Tracking Number. If it is one of these products, we need to select the Contract Number.
For all other one off orders we have with them, we assign our own Tracking Number starting with 00001. This Tracking Number cannot duplicate unless it is one of the aforementioned two products.Both the Tracking Number and Contract Number are in the same table. The user selects the Contract Number from a form (connected to the Contract Number table that has all the details on the contract) and the Contract Number is populated in the same table that has the Tracking Number.Each order must have a Tracking Number (no null)..Not all orders need a Contract Number (null okay).The Tracking Number and Contract Number combination cannot duplicate.I tried setting the primary keys to more than one field in the table, but they cannot have null values.
If not... I have been working on Plan B.... an AfterUpdate on the form (either the form or a field... don't know yet) that looks at a query that only has results if there are duplicate values.
Checking For Duplicate Values
May 10, 2005Hi,
I have a form in a database for our products (doors). I have a button that duplicates one of these records (all new products are based on standard template records).
When this record is created a new product number is produced by the system which was the number of the original (template) record plus the customer enquiry number.
I want to be able to warn the user if they are trying to save this newly created record with a product number that already exists so that they can alter the number to be unique. It will also warn them if they re-number an existing record to another already existing product number. Since the field is defined as unique, at present the system says absolutely nothing and just doesn't save the newly created record which seems is a touch annoying!
I have tried several things with dlookup, dcount arguments but can't seem to get anything to work.
Hopefully someone here can point me in the right direction?
Thanks in advance

Help Excluding Duplicate Values
Feb 14, 2008Is there a way that in a query from several tables you can choose to exclude duplicates of a specific field?
In the query I'm trying to create I am going through and counting the number of customers in a certain time frame. I don't want to count a customer each time they buy something though, I only want to count them once. The dates of their purchases are held in a seperate table for purchases and the customer information is held in a customer table. The information I need is in both of these tables and each customer has an ID number which is how the two tables are joined.
When I tried using the DISTINCT code it still brought in all the purchases because the customer bought things on different dates. The only way I have ever used this, however, is to write SELECT DISTINCT at the beginning of the SQL instead of just SELECT. If there's another way to use it to do what I need I will try it as long as you tell me what it is.
How can I set up the query to bring in all the information I need but not duplicate the ID numbers?
Thanks in advance for any help I get!!!
Keep Duplicate Values In Query
Aug 27, 2015I've got a query where a particular field can have duplicate entries. I do NOT want to limit the properties to only have unique values. On the contrary, I very much WANT to keep those but I DO want to have something indicating that the duplicates are there. I can create another Y/N or true/false field to indicate this if needed.

Mar 8, 2013I have a table called Department. One employee may belong to more than one department. So I created three tables, Emptable, Depttable, and DeptDatatable. The Emp table and The dept table both have a primary key. Emp# in Emptable to Emp# in Dept Data Table. Dept# in Depart Table Primary key to foreign key in Dept# key in Dept Data Table. In other words:
Employee One to Many Department Data both using Emp#
Department One to Many to Department Data both using Department#
I have created a form for data entry for the young lady that enters the data. Right now, there are two entries in the department data for any employee that belongs to more than one department. My question is how do I create a form that allow the person that is entering data to only enter the employee in once and enter multiple values into the department field. How would it create then two entries into the Dept Data Table? I have been reading up about fields that allow duplicate data but this treats the fields like memo fields. I need to draw queries from Departments, so not sure if that would work. I also need the Department to be a list that they choose from.

ComboBox Problem With Duplicate Values
Feb 17, 2005I am using a combo box to select client records. The problem I am having is that there are several clients with the same last name.
The query behind the combo box sorts on Last Name, First Name.
When I (as an example) select the second listed duplicate name from the combo dropdown, The form is populated with the data from the first duplicate name. (example Jones, John or Jones, William).
How can I make sure that the selected name will populate the form?
Thanks
Duplicate Values In Dropdown:MOST URGENT
Oct 28, 2005I am getting the error in a grid which has combobox.
This combobox allows only to select unique values from the list.
Whenever i selects the same value in another combo which is already selected in the grid, its shows the popup with the below message and makes us not to click anywhere else in the application.
"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship.Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries, and try again".
And when i delete the duplicate value selected in combobox it shows the popup with this message "Index or primary key cannot contain NULL value".
I simply wants this :
Whenever user selects duplicate value, message must be displayed and user comes out from that combo.
Please help urgently.
Creating Duplicate Values Error
Mar 29, 2006I have a table with one primary key (ClientID) which is an autonumber (cannot be duplicated), and another field which is a number field which is set to a random 6 digits (also cannot be duplicated) whenever a new client record is created.
Now, the main database is on a desktop, and my partner and i are connected to this main database through our laptops whenever we're in the office. For the last 6 months, I had only the ClientID in the form (from the Client Table), and everything would work fine whenever we created a new record in the Form, even if we created a new record at the same time on our personal laptops, the numbers would automatically be increased by one w/ no error.
I just added the other field now, the regular 6 digit random number field, and sometimes (only sometimes) when we both have a different client and start a new record, we get error messages that says we're creating duplicates. When that error message comes up, one of us has to close down the form completely, and reopen and start a new record again. Not sure why this is happening. Here is the error message.
