Creating Duplicate Values Error

Mar 29, 2006

I 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.

Any help appreciated.!!

Modules & VBA :: Error Message On Creating Duplicate Record

Jul 25, 2013

I need to be able to produce an error on a form where the user attempts to create a new user that already exists. The error needs to be produced when the save button is clicked.

See below for the existing code on my save button which exists in form, 'frmAddEditUser':

Private Sub cmdSave_Click()
If IsNull(cboManagerID) = True Then
MsgBox "Please select a manager", vbExclamation, "Details Missing!"
Me.cboManagerID.Requery

[Code] ....

Currently, if I attempt to create a user with the same Payroll ID as an existing user, my 'User details saved' message box is displayed and to the user it looks like a new record has saved successfully which isn't the case.

I need a message box to appear displaying something like "Payroll ID n already exists" where n is the 'PayrollID' of the duplicate record. (Is it possible to combine a value from a certain control and ones own custom text?)

Note: PayrollID is a combination of letters and numbers, i.e. two letters, followed by 5 numbers, e.g. JD12345.

For reference, the table/field and and control are called, '[tblUser].[PayrollID]' and 'txtPayrollID' (on 'frmAddEditUser') respectively; it is from this field and control that I want the error to be produced if the user is entering the same values which are existing in 'tblUser'.

Tables :: Change Duplicate Values Error Message

Aug 14, 2013

How to control the below message to something like this through VBA:

"The Job: " & JobNumber & " already exists in the table." or to open an alternate form where they can make the change. Allowing duplicates is not appropriate for what I am trying to accomplish. I just want a friendly way of rerouting a user to understandable answer.

instead of this:

"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."

Forms :: Prevent Duplicate Values With Alert After User Enters Duplicate Value

Dec 30, 2013

We 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")

Queries :: Query Records With Both Duplicate Values And Different Values?

Jun 18, 2013

I'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').

Creating And Assigning New ID To Duplicate Records

Mar 8, 2012

There is currently a database which contains location information on a variety of different samples, each which is identified by a unique sample number (the primary key). However, when these samples are processed, they are split it half and each is assigned a second identifier for each half (in this case, an A or a B). Therefore, if originally there was sample 1, it will be split into 1A and 1B. My task is essentially to create a second database with further information for each sample half (1A or 1B), while maintaining a link to the main sample database to reflect any changes to the sample location information. So far I have been using a make table query that pulls from the linked table which links back to the main database and combines with another table that simply has one column called "Piece" which has an 'A' in the first row and a 'B' in the second row.

I am quite new to using access, but I have found this task fairly frustrating so far because it feels like I am trying to force access to work in ways that it was not designed. Essentially I would like access to create a duplicate entry for each sample in the original database, and force in an 'A' or a 'B', and combine these fields to create a unique identifier. However, I am running into a lot of issue when trying to append data from the original database etc.

Queries :: Creating Query Without Repeating Duplicate Relationships

Feb 13, 2014

I have two tables that look like this:

Table 1

LOCATION NUMBER , SIZE
1.12 ,100
1.13 ,100
1.14, 12
1.15, 12
1.16 ,150
1.17 ,150
1.18 ,100

Table 2

ITEM , SIZE
A , 12
B , 12
C ,100
D ,12
E ,100
F ,100
G , 150

I would like to do a query that Joins the "Size" in each table, and then matches an "Item" to a "Location". However, because of how a normal join works, I cannot seem to figure out how to limit the "Location" field from producing duplicates in the match.

I only want to have 1 location for every 1 Item.

Forms :: Creating Duplicate Record With Specific Fields Blank

Jul 21, 2014

I'm working on a form with almost a hundred various fields (it's what my employer needs). He wants to be able to create new records with much of the same information as the old ones by clicking on a button that will copy the information to a new record, then clear certain specific fields (or some process that will safely create the same result). I don't need specifics on how to write the same line of code for each and every field I wish to clear.

Say I have a form with 5 fields: part_number, part_owner, procedure, file_name, and date.

How could I copy the record to keep the fields part_owner and procedure the same, but clear part_number, file_name, and date?

All of the fields are from the same table (no, it's not normalized...).

Duplicate Values

Apr 19, 2005

I 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, 2006

I 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.

Forms :: Underlying Query In Subform Creating Duplicate Records On Form

Jun 18, 2014

I have an "Returns" master form that contains two subforms. The subforms contain items that we are returning back into our inventory. The underlying queries in each subform show only those records where the "Return Date" is null. The query(s) works fine, except that if there are 3 items that need to be returned there are 3 records that show in the master Returns form. I tried the Totals option in the query but the I need that Return Date on the subform. I only want one Returns master form to show the 3 records (not 3 records of the same master form).

Checking For Duplicate Values

May 10, 2005

Hi,

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

John

Help Excluding Duplicate Values

Feb 14, 2008

Is 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, 2015

I'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.

Duplicate Values For One Field

Mar 8, 2013

I 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, 2005

I 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?

Duplicate Values In Index, Primary Key Etc

Feb 27, 2006

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
