Good morning all!
I have a problem, I have a contact list table in my database such as name, addr, company, street, country etc. The problem is that I have multiple duplicates of the same data.
How do i delete the duplicates? Is there an SQL query that I can run to delete? How do I do it. Please help. Thanks a bunch!
Hello,
I have two related table: table_Company and table_contact. Now i have:
Table_Contact Table_Company
James Bolton -----------> MacDonalds
Hellen Kidman ----------> MacDonalds
Now, i wanna have one "MacDonalds" in my Company table, and delete the others "MacDonalds" and still have the relationship between my contacts and their company.
I have two tables that have duplicate order numbers. I would like to compare the first table with the second and then delete the records from the second that match.Can I set this up in a macro and run it every day?
View 2 Replies View RelatedI'm wondering if it's possible to create a Query / Macro / VBA or whatever works, to detect the duplicate records in a table and delete them with the push of a command button. Or, even to do this automatically when the database opens using an AutoExec macro or something ?. I'd like for one copy of each record to be left intact in the table.

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,

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")
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').

Have searched the forum but cannot find a suitable answer...
I have duplicates in my table that I need to delete but leave one existing record, e.g.:
ID Part Family Colour Cost
1 123456 HHH M98765 12.99
2 123456 HHH M64975 12.99
3 123456 HHH E79461 12.99
4 123456 HHH G13467 12.99
5 123456 HHH M98765 12.99
In the above example i would want to delete records 2-5 (based on Part and Family, even though the colours are different) leaving one there. If I run the find duplicates and then change that to a delete query then it deletes them all.
This needs to be done via a query as it is done in automation, so manually copying the table structure and applying primary keys to the fileds etc. is not an option.
Any bright ideas?

I have a list of projects and am creating a query that tells me their duration based on beginning and ending dates. These beginning and ending dates can be edited by the user, and frequently, there are multiple beginning dates. When I query the projects, instead of getting unique project numbers on the left hand side to create unique rows, I get many of the same projects with different start dates. I would like to use the FIRST start date only for every project and not have multiple rows with the same projects being counted multiple times.
Is there any way to delete the excess rows and keep the original row? I've read a lot about using DISTINCT and UNIQUE INDEX with SQL but it seems as though these are only available for tables and not queries. Bright ideas, anyone?

Help please!
I have a form (frmHalfTab) built on a table (tblHalfTab2) that has existing data in it. In the very near future, I will be uploading additional data to this table via excel cut and paste. What I want to do is search for and eliminate duplicate records that have duplicate data in TWO fields, (MemberNum) and (MBRDrug), so that if MemberNum is "10" and MBRDrug is "Zzz" for more than one record, the duplicated records need to be deleted, OR a check box needs to be checked automatically for all the identical records, the original and the duplicate(s). I wanted to put this behind a button, if possible.
Now, I have created a duplicate query that will find the duplicated records, but I'm not sure how to use it to get rid of the duplicated records or check the checkbox appropriately. Should I ditch this query and choose a different route, or am I on the right track? Thanks in advance for your help.:confused:

I have a table that has 1335 records in, and columns names, Title, First Name, Surname, Address, Address2, Town/City, County, Postcode.I want to know how to write a SQL code, which will locate all the duplicates that match the First Name, Surname and Postcode and delete them, but keeping 1 copy of the duplicate.I have created a query to locate the duplicate records, and I have put the SQL code there. I tried changing this, however it would delete all the records, so I am not to sure what to try...
SELECT SurnameSearch.Title, SurnameSearch.[First Name], SurnameSearch.Surname, SurnameSearch.Address, SurnameSearch.Address2, SurnameSearch.[Town/City], SurnameSearch.County, SurnameSearch.Postcode
FROM SurnameSearch
WHERE (((SurnameSearch.[First Name]) In (SELECT [First Name] FROM [SurnameSearch] As Tmp GROUP BY [First Name],[Surname],[Postcode] HAVING Count(*)>1 And [Surname] = [SurnameSearch].[Surname] And [Postcode] = [SurnameSearch].[Postcode])))
ORDER BY SurnameSearch.[First Name], SurnameSearch.Surname, SurnameSearch.Postcode;
I am trying to create a query to find duplicates and delete the duplicates. The result will eventually be used in another query (append query) to update a table.I have a table with 4 columns lets say for simplicity they are A, B, C, D
I want my query to find duplicates within B and deleting them. The catch is before deleting them I need to look into column A to ebsure they are actually duplicates. Example below
Example
A B
John Doe Tires
John Doe Wipers
Allison Doe Tires
Allison Doe Tires
As you can see from the above Tires is a duplicate and need to be deleted.
A B
John Doe Tires
John Doe Wipers
Allison Doe Tires
The charity that I volunteer at has a web site through which they receive donations.
Most of the COMPANY names that they receive through their website are JUNK.
I would like to have a system to delete duplicate company names:
A = first programmatically delete all company names that are GOOGLE and this will remove about 60% of their spam
B = next group all Duplicate Company names, which will be removed manually
I know this probably has been asked a 1000 times but I don't seem to be able to edit the uncommented VBA-codes I found online to work on my database.
I already ran a query that shows me the duplicate records of my original table. Now I m looking for a way to
a) delete all duplicate records (not just specific ones by using a criteria) and
b) unite the unique records (result of a)) with the original ones that were not displayed with the "find-duplicates-query" ....
I need developing a new delete query criteria to add onto existing delete duplicate queries for deleting duplicate values. I need the new delete duplicate query to take precedent over the other two so that those values retained in the first query are kept retained after going through the second and third delete queries. Attached is a document laying out the request.
View 1 Replies View RelatedI 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
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.
-WM
is there a way to stop duplicate values appearing in a query result.
i querying a table but i dont want to see the same value twice ca i prevent this?
i 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
End Sub
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.
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

hi again,
I'm building a search function into my database and everything's fine apart from the fact that i have duplicate values in my combo boxes.
For example in the combo box 'market' i have many fields named Europe.
How do i replace these repeated values with one distinct value?
Cheers
