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
I have two simple tables. I want to delete the records from Table1 that are on Table2. I've created a select query that gives me what I want but when I change to a delete query, I get this message: "Unable to delete from specified tables"
I think my problem has something to do with security but I can't figure out what to change.
i have a table1 in my msaccess and i linked another table in mysql to ms access, (table2). when table1 matches the record in table2, it will delete the record in table1.
my query is delete * FROM Table1 where table1.artid = table2.artid;
but it always ask me the value of tbl2.artid, the value of tbl2.artid is in the database of mysql and it has already records...
how can i compare the records of table1 (msaccess) and table2 (mysql) and delete the duplicate records? :D
I have a table that has many duplicate records. I tried importing the table and setting the field to no duplicates but did not work. How can I delete duplicate records. The primary Id id fine I have another field that I can use. it is a BAC number that is repeated many times. Here is the table I need fixed.
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.

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?
On the below data I need to delete records where dep is blank or the same for the same ID. So I need to find and del recNr. 1,4,5. Any help will be appreceated!Thanks
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:
Please, anyone know how to delete few table's record by using one query ? I want to delete 10 tables, all the records inside at one times. I tried there is only one tables at a time. Is that imposible to do that?

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?
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 have a question on hiding duplication record using query.
The fields in the query are:
full name(trainee), NRIC(trainee), gender(trainee), preferred language(trainee), company(trainee), course name(course), course date(course), competent(course), class(course), L3 survey(trainee), L4 survey(trainee), num of month(course)
When the query is being run, it will show all the people that have not done the L3 and L4 survey after 3 month. The the query will be convert into a form. However the problem is that the record will show a few same name due to one person can take more than 1 course. therefore, the data in the course table will always be different.
How can i make the record only show 1 name even though they have different course name.
I had tried putting 'yes' for unique record and unique value but it did not change the result.
current SQL query:
SELECT DISTINCT trainee.[Full Name], trainee.NRIC, trainee.Gender, trainee.[Preferred Language], trainee.Company, course.[Course Name], course.[Course Date], course.Competent, course.Class, trainee.[L3 survey], trainee.[L4 survey], DateDiff('m',[Course Date],Date()) AS [Num of Month] FROM trainee INNER JOIN course ON trainee.NRIC = course.NRIC WHERE (((course.Competent)="c") AND ((trainee.[L3 survey])=False) AND ((DateDiff('m',[Course Date],Date()))>=3)) OR (((trainee.[L4 survey])=False) AND ((DateDiff('m',[Course Date],Date()))>=6));
I created 3 find unmatched queries from the query wizard. The first one works great. I can delete a record in the query and it deletes the record in the main table.
The second one allows me to delete a record and gives me the pop up box that says " you are about to delete 1 record". I click yes, but when I check the table or reopen the query the same record reappears.
The third query does not even give me the option to delete.
I can create a regular select query and delete the records form 2nd and 3rd but not from the queries made from the unmatched wizard.
I am using the same fields in all 3 queries.
I do not have enforce referential integrity or the other 2 options checked in the relationship properties. (not sure if this makes a difference.)
I even tried to redo the unmatched queries but I get the same result for all 3.
I want to be able to delete the records in the other 2 queries.
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 have two tables. PreOrder and Order Tables. When our customer actually order a product, I want all information of that product to move from PreOrder table and append it to Order table. Currently, my user has to run an append query to add the record from PreOrder and add it to Order table. After that, she has to run a delete query to delete the record from PreOrder table. Since our query is setup to run by date, and order number..My user has to type the same thing twice. Is there anyone out there know the easy way? Thanks in advance..
I'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 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.
When we browse through records in a subform we store the records in the database.When we want to delete a records for example the third record from the five records always the first records will be deleted. How can we delete the records where the cursor is at? When we are at the third record and press the delete button the third record from the list in the subform should be deleted.
Code:
Option Compare Database Dim FocusBln As Boolean Private Sub Identificeer() Me.[Datum Aangemaakt].Visible = True Me.[Datum Aangemaakt].SetFocus If Me.[Datum Aangemaakt].Text = "" Then
I have a query based on two tables, joined on one field (this field is the primary key in Table A. Table B doesn't have a primary key). When working inside this query, it gives me the option to delete records. However, when I try, the row disappears from the query but then if I save and close and either re-open table A or the resulting query, that record is back. It doesn't actually delete. If I go to table A directly and delete it, it's gone for good.
How can I make it so that when I delete the record inside the query it actually deletes? And if that's not an option, can I make it so that it doesn't seem like I can delete records inside the query so that people don't make the mistake?
I want to find duplicate records based on FirstName and LastName and delete the duplicate. Also, I want to delete any records which have a blank FirstName and LastName.
I have a database with a table that uses a numeric field as a PK. If I use the built in "Duplicate" Command button on a form it creates an exact duplicate of the record, which then Access won't allow because the PK is no longer unique.
Does anyone know of a way that I could make the number be the max number + 1 when I click the "Duplicate" Button?
