Help Filtering Duplicate Records From Query

Nov 28, 2007

Dear Experts,
I have created a database with queries that is working fine, however there are many records that have the same information that can not be removed easily, is there a method anyone knows of that can filter the records produced from a query to remove duplicates? i.e. 'select distinct' but for the whole query after the search parameters have been entered.

e.g. the search query is producing, after the refined search values are entered:
414353p - Fiat - 1.6 - MLS
414353p - Fiat - 1.6 - MLS
How can i then apply a filter to automatically reduce these duplicates to just one entry for the whole form?

Thanks

------->>> Please Help On Filtering Out Duplicate Records.

Mar 14, 2008

Hi there,

I'd like to filter out so that the name only appear once base on LastOfDate.

Sample data in query

Customer_____Date__________Product
John_________02/02/2008_____A
John_________05/03/2007_____B
John_________03/06/2006_____A
Nick_________04/04/2006_____A
Nick_________04/04/2007_____B
James_______05/04/2008______A

So in the query, I just want to have John, Nick and James appear once with the LastOfDate.

The result should be
John_________02/02/2008_____A
Nick_________04/04/2007_____B
James_______05/04/2008______A

I included the db file which only perform LastOfDate and unique name, however since John has product A and B, it won't get rid of B.

SELECT DISTINCT query1.Name, Last(query1.Date) AS LastOfDate, query1.Product
FROM query1
GROUP BY query1.Name, query1.Product;

I just want one Name, LastOfDate and one product, regardless of A or B.

Thanks,
Isabel

Problem Filtering Records From Query

Jan 19, 2007

I have a database with 2 tables. Table1:drawing number and drawing title and Table2: date, action, status. Table2 gives the complete history of our internal review process.

Example:
Number=001, Title=Drawing001
date=01/01/07, action=drawing received, status=
date=02/01/07, action=drawing checked, status=approved
date=03/01/07, action=approval sheet issued.

Number=002, Title=Drawing002
date=04/01/07, action=drawing received, status=
date=05/01/07, action=drawing checked, status=not approved
date=06/01/07, action=approval sheet issued.

I need a report which lists just the 'not approved' drawings. I've been able to add a query which lists the drawings but I loose the complete history, i.e. drawing recieved date.

Is there anyway I can display all the fields but only for those drawings which are 'not approved'

Query For Duplicate Records

Jul 9, 2007

I am creating an ordering system which comprises of amongst others, these fields:

ID
OrderHdr
OrderLine

I want to ensure that if a user enters an ID, OrderHdr and OrderLine that this combination does not already exist elsewhere within the same table.

I have written a query like this:

COUNT OrderLineDetails.id, OrderLineDetails.orderno, OrderLineDetails.orderline
FROM OrderLineDetails
WHERE (((OrderLineDetails.id)=?) AND ((OrderLineDetails.orderno)=?) AND ((OrderLineDetails.orderline)<>?));

I will be replacing the "?" with the relevant form fields from the form, but how do I run the query and store the result in a variable and prevent the user from carrying on until they change any of the fields until there is no duplication.

Eliminate Duplicate Records In A Query

Jun 5, 2007

I know there a many posts about eliminating duplicate records because I did search, but I did not see anything that really answers my question.

I have a query in a local Access database that is using a Linked table from an SQL database managed by our corporate IT department. I have read access to only certain tables / fields in the SQL database. My query is based on 3 tables from the database and I have them linked together in my query.

When managers move from one site to another, they are given a different TeamID number. However, until they are replaced, the manager will have more than one TeamID assigned to him in the SQL database. Evidentally, the way our IT has the SQL database structured, when I query open items it duplicates the record for that manager because he has 2 TeamID numbers. So the only field that comes up differnt in the duplicate records is the manager's TeamID number.

I would like for my Select Query to ignore the duplicate record. I know I can use an Append Query to copy the data temporarily to a local table and set the proper fields as Primary Keys to do this. However, it would be nice if I did not have to go to all that trouble.

Is there a way to eliminate duplicate in my Select Query?

As always, I appreciate the help.

Jim

How To Sum Duplicate Records In Union Query

Oct 30, 2012

(Example of my data)

Order ID Customer ID Purchase Amount
1 17 $14.95
1 17 $7.35
2 21 $11.90
3 27 $64.80
3 27 $31.13

I have two tables with pull in data. What I'm looking for is a query that would combine the customers purchase and sum the purchase amount field. The tables are unioned as some customer data is in one table but not the other and joining them excludes some of this data. Ultimately I would like to see is

Order ID Customer ID Purchase Amount
1 17 $22.30
2 21 $11.90
3 27 $95.93

Queries :: Removing Duplicate Records In Query

Apr 24, 2014

Im 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.

Duplicate Records In Query To Join Fields From Several Imported Txt Files

Jan 10, 2008

Hi all,

I have the following issue:

In my job we work with several raw data .txt files exported from Oracle ERP system. These data include information about: inventory, sales, backorders, purchase orders, forecasts, product line.

My goal is to put information from all of these imported txt files together to create an easy to use snapshot file.

The common field between al of these files is the item description. I have an issue where records are repeated for several fields every time the same item description is showed. For example for the same product description the january sales forecast QTY is repeated on several rows because there are several orders for this product description. Is there a way to make forecast QTY appear only once but keep the multiple orders and their information?

Example of current result

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).

Queries :: Mass Duplicate Main Records And Related Subform Records

May 29, 2014

In my simple database (attached), I need to mass duplicate Tasks and their Notes.

I have three tables: tbTasks (PK: Task_ID), tbNotes (PK: Note_ID), jtbTaskNotes (FKs: Task_ID and Note_ID). jtbTaskNotes is my many-to-many junction table that ties Tasks to Notes.

The main form (fmTasks), bound to tbTasks, has a subform (sbfm_TaskNotes) that displays notes associated with each Task. On themain form,you select which Tasks you want duplicated via a checkbox. The append query (quCopyTasks) will duplicate all tasks that have the checkbox checked. All good there. However, I can't figure out how to also duplicate each task's Notes.

I found Allen Browne's solution [URL] ....., but that only handles duplication of one record at a time, whereas I need to duplicate many records at a time (sometimes 10+ records). How do I go about duplicating multiple Tasks and their associated Notes?

Before you ask "why are you duplicating records?": There are times when tasks need to be re-accomplished and therefore need to have a new record. It's easier to duplicate records than it is to hand-jam everything again.

Qry Results Show Duplicate Records, Records Are Not Dup In Table.

Nov 16, 2004

I have built a qry that initially shows the correct information. For example.

tblContent has 289 records with a Type = Class.

I built a Query to select from tblContent Type = Class and I get 289 records. I add additional criteria of Progress <>"Not Scheduled", I then get 206 records. I then add additional criteria Last Name <>"Demo" And <>"Care" And <>"Support". This brings up 200 records, but the query appears to duplicate each record 3 times. I do not have 3 of the same types of records.

The SQL Statement is below

SELECT tblProfile.LoginName, tblProfile.FirstName, tblProfile.LastName, tblProfile.Organization, tblProfile.CostCenter, tblContent.Title, tblContent.Type, tblContent.Code, tblContent.[Date Assigned], tblContent.[Date Started], tblContent.[Last Accessed], tblContent.Progress, tblContent.[Date Completed]
FROM tblProfile INNER JOIN tblContent ON tblProfile.LoginName = tblContent.LoginName
WHERE (((tblProfile.LastName)<>"Demo" And (tblProfile.LastName)<>"Care" And (tblProfile.LastName)<>"Support") AND ((tblContent.Type)="Class") AND ((tblContent.Progress)<>"Not Scheduled"));

The qry is named qryPhysical Class. I have provided the link to view the database. Can you help me?

Filtering Records To Then Add A New One

May 25, 2005

Hi

I wonder if anyone can help. I attach a table that is a material list (27000 records). When I add a new material I want to be able to see the last part code I created for a particular supplier.

For example C001, C002 and C003 are for a supplier company called Chapters so I would scroll through the combo box search list in the form for the last one and create a new record called C004. The problem is that E00001, E00002 for a company called Edwards supplies 20,000 items so it's a long way to scroll through to create a new part code called E20001. How can I show in the form what the last part code is for each Supplier?

I attach the form and table as I'm not very good at explaining this, although I have had to delete approx 20000 records as the database was too big to be posted. Any advice/help would be greatly appreciated, many thanks

On the form there is a combo box to select discipline (Civil, Electrical, Mechanical) and a combol box to select the volume the drawings are in (Volume 1 - foundations, Volume 2 etc).

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').

Need Help On Filtering Records Using Combo Or List Box

Feb 18, 2006

Hi, I need help on my search command. I am hoping to be able to use a combo box or a list box coming from a table as my criteria to use to filter records from a form and present it a subform/subreport upon clicking the command button. Ideally I should have a form wherein I will have a either a combo box or list box for my criteria, a subform/subreport, and a command button. When I select a particular item on the combo box or list box and I click the command button, the subform/subreport would show me records matching only the particular criteria I selected.

I tried using several approach but it's not working, I don't know what I'm doing wrong. Please help me, I am just learning how to do this all by myself.

First Approach:
I tried using a list box to list all the countries I have available from the country table and a command button so when I select a country from the list box and click on the command button I will be able to show on a datasheet view only records matching the country criteria.
This is the code I used:
__________________________________________________ _______________
Private Sub Preview_Click()

DoCmd.OpenForm "qrysumcountry subform", , "Country", "Country = [List4]"

End Sub
__________________________________________________ _______________
But everytime I click on the command button Preview, I am always asked to enter parmeter value then when I type the country that's when it shows the record in forms format matching the criteria country but when I dont type anything and click ok, it just shows a blank form and indicates it's filtered but no record is showing. But I click cancel, it shows a Run-time error '2501'. why does it still have to make me type the parameter if I have selected it on the list box already?

Second Approach:
On the form: I used a combo box, a subform/subreport and a command button. On the combo box I have to show different countries available on my country table. on the subform/subreport I have used my a form created from a query. I want to select from the combo box a particular country and used it as my criteria to filter the records I have on my subform when I click on the search command button. I tried following the sample given by gromit but it doesn't want to work on my database.

This is the code I followed:
__________________________________________________ _______________
Private Sub btnClear_Click()
Dim intIndex As Integer
Me.cmbCountry = 0

End Sub

Private Sub btnsearch_Click()
Me.frmqrybyCountry1.Form.RecordSource = "SELECT * FROM qrybycountry" & BuildFilter

Me.frmqrybyCountry1.Requery

End Sub

Private Function BuildFilter() As Variant
Dim varWhere As Variant

varWhere = Null ' Main filter


'Check if there is a filter to return...
If IsNull(varWhere) Then
varWhere = ""
Else
varWhere = "WHERE " & varWhere

' strip off last "AND" in the filter
If Right(varWhere, 5) = " AND " Then
varWhere = Left(varWhere, Len(varWhere) - 5)
End If
End If

BuildFilter = varWhere

End Function
__________________________________________________ _______________
After selecting on the combo box and click on the command button it just shows all record. It doesn't seem like it is reading what I selected from the combo box as my criteria to filter the records. What could be I be doing wrong? Honestly, I dont understand what is happening to the code here especially the BuildFilter function.

Please help me, I would really want to figure this problem out. Thank you so much.

Queries :: Filtering Out Similar Records

Jun 20, 2013

I have a query that shows member check-ins to a fitness facility. Customer scans their membership card and it logs their customer id, scan date/time (date and time are one field), name, etc. Sometimes the customer will scan their card multiple times if they've left and come back, but I only want to count their first scan. I have a second query that runs off of this one and counts visits by hour for a date range.

So my question is, how do I filter out subsequent scans on each day in a query and how do a I do that when running the query for multiple days? So in the multi-day query I want to count each day they came, but only the first scan of each day? How to do this in the query design grid...
