I have a table that has mutliple records for the same person. I know how to create a query to remove duplicates but i don't know how to create a table to remove duplicates but keep the most recent record. Is this possible?
ie
client status date
123 A 1/1/07
123 C 2/5/06
123 A 9/3/07
results
client status date
123 A 9/3/07
Ok well I thought I was doing this right but it appears I have not. I am drawing data from two tables. Both of them related by the person's name. One table I am pulling the unique ID number, the other table contains the name. I have a PO (Purchase Order) field being pulled from the table that holds unique ID. Or lack there of, so I am pulling all the records that contain no PO number. However duplicate unique ID's are being pulled. The way my query is set up now is:
Unique ID Number
Name
Count (Number of Procedures)
Charges
PO Number - Criteria: "Is Null"
I have also right click in the table view area, in the properties I selected Unique values. I have to assume that this would have held back any Dupes from the output. However this is not the case. When I looked in the help files the only thing I could find was:
http://office.microsoft.com/en-us/a...0840151033.aspx
Quote: "If you want to see only unique values in a result set, you can specify that you want to exclude duplicates from the result set.
In the Database window, click Queries under Objects, click the query you want to open, and then click Design on the database window toolbar.
Right-click the background of the Diagram pane, then choose Properties from the shortcut menu.
Select DISTINCT values.
The Query Designer inserts the keyword DISTINCT in front of the list of display columns in the SQL statement.
Note If you use the DISTINCT keyword in Microsoft SQL Server, you cannot modify the data in datasheet view."
The problem with this is my properties box does not offer a Distinct Values option. So my question is. Is there an expression I can place in the Unique ID field that will exclude any duplicate records.
Sorry for the book

I'm having a problem removing duplicate records from a table. It should be easy but I can't suss it.This is an example of the data in my table:
Code:
RefDateStatus
113007111/06/2015Do Not Pay
114454306/07/2015Do Not Pay
115760714/05/2015Do Not Pay
116520705/05/2015Do Not Pay
117670108/05/2015Do Not Pay
118036218/05/2015Do Not Pay
118517015/05/2015Do Not Pay
178734020/07/2015Do Not Pay
182809915/07/2015Do Not Pay
184226010/07/2015Payment Due
184226022/07/2015Payment Query
As you can see, there are 11 records here but the last two records have the same reference number. I need my query to show the first 9 records + the record from the bottom two with the latest date (22/07/2015).
I currentlyt have a search form that searches criteria based on a textbox. After entering data a macro runs, and opens up a query with the results. After that query opens i have macro that runs a duplicate query off of the query initally opened based on the search results. What i would like to have is a macro that removes the duplicate records from the duplicate query and display the remaining records.
View 1 Replies View RelatedIm trying to write a query that shows all the container movements. Yet when I run the query qryFullHistory I get a duplicate value for container Off Island. Ive tried adding some criteria that says that the DateRequested has to be between the ImportDate and ExportDate but that doesnt seem to work. There are duplicate entries for container Off Island in tblContainerDetails as the same container has arrived and left and then returned on another voyage. Yet there is no entry for the second voyage in the tblMEMRContainer.
A brief description of the tables is:
tblMEMR Movement requests details
tblMEMRContainers the containers that were moved on the movement request. There can be more than 1 container for each request.
tblContainerDetails details and dates for the container when it arrived and when it left
There are other tables but these are the 3 that are used in the query.
I have a table with at least 13.000.000 records. There are many duplicates records... For example
ID Name Family mobile car number chassis Register_Year
1 Roy Jalbout 9999 123456/G ASF4546 2005
2 Roy Jalbout 9999 854658/G GRK554JFJD 2009
3 Tony Elishah 1234 854658/G GRK554JFJD 2012
4 Sam Markos 5478 854658/G GRK554JFJD 2014
5 Roy Jalbout 9999 123456/G ASF4546 2005
As you can see ID Number 2,3,4 have the same car but every one bought from another so it's not duplicates
The duplicates here is the ID's number 1,5. So how to remove the duplicates. I remember you i have at least 13.000.000 records. I try to make a query to find duplicates then i make a copy of the original table and than i should make a primary key then append the data from the original table to the copy table, but here i have more than one criteria
When I made a query to find duplicates the result was 680.000 records and every one have a minimum 2 duplicates an maximum 4 duplicates so it's about 2.500.000 duplicates records at least....
Hello all,
I have made a crosstab query that is sporatically making duplicate counts. I'd like to know how to fix the problem, but more importantly - I'd like to know why and how my query is giving me these results so I can avoid making this same mistake again.
The relationship is set up so that all records from one table are returned, with only matching records from the other - so no problems that way as far as I can see. This is my crosstab query that is giving some counts of the same record as being matched sometimes two, three, or even four times:
TRANSFORM
Count([Testing DB].[DB_ID]) AS [CountOfDB_ID]
SELECT
[Testing DB].State, [Location].[North], Count([Testing DB].[DB_ID])
AS [Total Of DB_ID]
FROM [Testing DB] LEFT JOIN [Location] ON [Testing DB].[Address] = [Location].Address
WHERE (([Testing DB].[Window Length]) Is Not Null))
GROUP BY [Testing DB].State, [Location].[Size]
ORDER BY [Testing DB].State, [Location].[Size]
PIVOT Format([Date],"mmm-yyyy");
When I do a simple query for a list of the records being counted by this query, I can see the duplicate entries and can eliminate them simply by adding "Distinct" to the select statement - but I haven't had any luck adding any kind of distinction with this crosstab that will do the same.
How can I eliminate duplicate counts of records in my crosstab? If anyone has a suggestion, it would be much appreciated.
I have a database with an import process which normalises incoming data and appends to various tables. No issues with that. I also have a function within that process which counts the number of new entries for a summary popup when the process has completed.This works by querying the staging table, prior to the append, into a recordset and using the .RecordCount to increment the count (multiple files can be imported at once so this effectively provides a running count, per file, to give a total for the whole import)
I thought it was working fine but this morning I noticed that the count which appeared on the popup was 1 greater than the number of actual new records. I checked the source files and noticed that, for whatever reason, there was a duplicate entry in there. So I presume that's why the count was out by 1.
There's no integrity issue in the main tables as the composite primary keys ensure that duplication shouldn't be a problem. Indeed, the record in question, duplicated in the source, appears only once in the main table post-import. So not too worried about that.
However, I need the count in the popup to be accurate (it tells the users how many new entries require further investugation). And what's puzzling me is that I use DISTINCT in the query, which I would have thought should eliminate any potential dupes in the recordset and thus provide the correct count. It seems it doesn't?
Code:
Public lngNewBalancesTBI As Long ' Defined in a separate module...
-------
Dim dbs As Database
Dim rst As Recordset
Dim strSQL As String
[code]....
Why the dupe, which is still present in the staging table, also makes it over to the recordset, even though I'm using DISTINCT?
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")

Hello,
I am totally new at this database stuff. I have been searching the archives for a couple hours and confused on how to accomplish what I need to do. I saw references to using a module but I have not used that feature yet.
I am using Access 2003. I need to remove/delete " - " space dash space, "-" and "&" from a string in one field (DGName). I'm trying to do this with a make table query
DGName
P1000
P1000 - SMLS
P1000-CA (not a type error)
UD000 - C&B
V-NET
and I want it to come out like this
DGName
P1000
P1000SMLS
P1000CA
UD000CB
V-NET
Thanks

Hi there I am extracting user names from e-mails in an access database.
I built the following command to do it
Left([E-Mails by Source - Test]![E-Mail],InStrRev([E-Mails by Source - Test]![E-Mail],"@"))
where [E-Mail] is the e-mail address.
It works great. But I still get the @ and the end of the name.
Any idea how I can get rid of it (other than using find and replace)?
Thanks for your help.
I posted an earlier question about an Access query export to Excel putting leading apostophe (') before all data.
To remove them I thought I would use Find/Replace but the Apostophe is not recognised!
Is there a way (programmatically) to remove the first character of each data entry in each cell in a column?
thanks in advance

Can anyone please help me, I currently have a series of queries that are called by a macro, these create a number of tables. But when each query runs it provide a prompt stating what it is doing, my question is can these be stopped so that the queries run without a user being present.

I have two tables: “tmptable” and “CC_CODES”
Both tables contain the same data; however the “tmptable” contains updated data. How can I compare both tables and remove all the duplicate in the tmptable, leaving only the updated data.
I will be comparing the fields “IsMandatory” from both tables
I have a field that contains serial numbers. The serial numbers are entered in difference formats. Some will have dashes, spacing and periods separating the numbers (example: 06-65432 or 06 65432 or 06.65432). I am trying to create a search field for this and the different formats makes it difficult. Is there a way to remove all separators so that all parts of the serial number are together?

I am running a query to return records from a table. I want to eliminate records from the query if the values contained in one field are duplicated. I have tried using the DISTINCT keyword but it only works if the entire record is unique or if I was retieving just one field
Any suggestions appreciated
can someone help:
in a form I've created showing products bought, when I add a new new order it still keeps the previous order's data, how can I prevent that from happening?
cheers
This may seem like a silly question, but I can’t find the answer to it on this forum. People only say 'Remove the table links' but never how. I can’t seem to be able to remove the table links completely, so I only have one database file (no backend or frontend). I can’t seem to do it though the Table link manager or any other way. Any help?
Thanks in advance

Hello,
I want to remove the first four characters from a field in a query.
The data are not always the same length, but it will always be the first four.
Example.
vmc_ml120e21/p -> ml120e21/p
Is that possible and how??
Thanks in advance.
