Mar 11, 2007I have a table with duplicate rows. How do I de-duplicate the table so that there are no duplicates and find out how many duplicates there were in the table.
Thanks:)

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")
Duplicate Last Name And First Name

Duplicate Tag #
Mar 19, 2008Hi All,
I have a table that has a device column and a tag # column, I want to pull out a report that shows duplicate tag # for different devices, the tag # can only be assigned to one device, I received an excel sheet that has to be fixed, I have the sheet in an access table. Please help. For example: device 123 and device 345 have tag #abc. I can’t simply create a query to show duplicate for tag# because I can have duplicate # only if it’s the same device.

Sep 13, 2007I currently have a table that had 30 fields, the unique fields are survey, date, and business name. I'd like to create a query that will display all of these records so that i can get rid of them. They were imported from another table that another user created. If survey, date, and business name are identical i'd like to get rid of them.

Duplicate Posts
Jul 11, 2005i have a table with 3 fields: ID, line_item, and pay_app.
line_item and pay_app are linked to other tables in a one-to-many.
For every pay_app, there can be up to 100 line_items. However, I only want each line item to appear once (at most) in each pay_app. I want to prevent the same line item from showing up multiple times in the same pay_app. Essentially, I want to prevent duplicate entries, but with a stipulation, if that makes sense.

Duplicate Validation
Feb 22, 2006Hi,
I need to make a database which wont allow any double bookings.
I've got all my bookings in a query and when a new date is entered (via a new bookings form) I need to make sure that date entered doesn't already exist in the query. I have tried a DLookup but it didn't work, however that is more than likely to be a user error, heh.
I've jumped in at the deep end doing this database. I've only done a few step by step databases before hand and the Access Help has sometimes helped my problems but I just can't find the solution on my own for this, I need somebody elses help.
Thanks a lot

EDIT: sorry if this is in the wrong area, I couldnt think where to put it
Duplicate Data
Feb 10, 2008Hi I've just signed up to the forum.
I'm currently working on a booking system, where clients can make appointments.
However as I am fairly new to access, I would like to know how I can inforce some sort of validation where for example if a client makes an appointment on 17/02/08, then it checks to see if there are any current appointments of theirs on the day, if there is, then an error message would occur
Help With Duplicate Fields Please!
Dec 9, 2004Hi, doing my project at college, decided to do a EPOS simulator for my sisters business based around barcodes etc and tied to a database. i've just knocked up something after normalising my data to prototype it to see if it is viable. I'm having problems with duplicate field entries. My db consists of essentially 4 tables at this point:
User : user ID, User Details
Product: Product ID, Barcode, Description, Cost Price, Sell Price
Transaction: Transaction Number, Date, User ID, Transaction Total
Transaction/Product - a compound key which is to manage the many to many that exists between Product and Transaction tables.
I am wanting to allow multiple entries for the same item, i.e. multiple scans, not a single sacn followed by a quantity. I keep getting an error message though that syas I am duplicating fields. I have tried altering the Index property for the fields in the Product/Transaction table but htis has had little effect.
Any thoughts please as to how to do this? I have attached the db for examination.
many thanks, Lol :D
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
Trying To Duplicate Data
Jun 29, 2006I have a medical database (Access 2003) containing information about patients. There is 1 form that is used to enter the information and a check box to say whether the patient has cancer.
I run a simple query to select the cancer patients.
I want to be able to add a large amount of information about (only) the cancer patients through a separate form. I also want a neighbouring hospital to be able to add cancer patients.
The ideal solution (I think) is to create an extra table to contain the extra information for cancer patients, and some of the informationfrom the original table. Cancer patients need to be automatically added to the cancer table once the "cancer" box is checked.
So far I have not ben able to achieve this - a create table query does not update automatically. I have tried creating a new table with the cancer information and creating a relationship between the tables and basing the form on the cancer table and a select cancer query. This does not work either.
Please can anyone suggest a solution! Do I need another database?
Thanks
Duplicate Records
Oct 24, 2006Hi
I have a table (which is populated by people filling in a form) which contains two fields:
Section
WeekCom (e.g. week commencing)
I want to make sure that the form will not allow someone to make a double entry. For example, if Sally goes in and says enters "Benefits" as the section and "WeekCom" as 15/10/06, and then Ben tries to do the same - the form will not allow Ben to enter it.
How do you do this please? The table does not have a primary key at the moment....is there any way of doing it without setting one of the fields as a primary key?
Thanks
Maria
Duplicate Identifier
Mar 5, 2008hello,
In excel i used the following formula =IF(COUNTIF(U$2:U$900,U3)>1,"Duplicate","")on one field to find duplicate, but I cannot come up with similar formula on column fields in a table.
Any guidance?
Thank you in advance

No Duplicate In Combo
Oct 9, 2005Hi,
I have a table containing 100s of records. One of its field is Entry_Date. There may be more than one record entered in same date.
Example:
Entry_Date Item
24/09/2005 abc
24/09/2005 pqr
25/09/2005 xyz
24/09/2005 lmn
and so on..
I created a combo on a form based on a query to get all the data from the above table. When I click the combo it shows me all the records. But I need my combo not to show duplicate records.
Example : The combo box should show the records as follows:
24/09/2005
25/09/2005
I do not need other fields in the combo except date field. I have some further actions to take based upon the date I selected in the combo. I dont find 'Hide duplicate' option in its property.
How could I do that?
With kind regards,
Ashfaque
