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

Basically i have a mortgage application system which im running a query on to see which applications have been completed in the last week or period up to now ie. last week, last month, last 3 months.
basically each application or CaseID has one or more applicants. The majority of them have two applicants. A few have one.
Problem is when i run this query which shows me: - CaseID, CLIENTNAME, LENDER, PRODUCT, MORTGAGE RATE, LOAN AMOUNT -
it brings up these fields but i only want one occurence of each CaseID????
CaseID Forenames Surnames PRODUCT RATEDateCompletedLoan required
2821NothandoDube71116.6920/01/2004£63k
2821Sipho Dube 711 16.69 20/01/2004 £63k
2909Hobbly Chise 726 15.69 31/01/2002 £164k
Get the picture? Both Sipho and Nothando are applicants on the same mortgage but i only want to show one name. Anybody know how to help me out???
Ive taken up this existing system, so i think there's possibly a normalisation problem thats causing this. But i need a quick fix for now rather than redesign the whole system.

Hi all,
This is an intersting question that my friend ask me... hope someone can help to solve it.
In a combo box i use to list out all the company in a table that with the duplicate of the company is allowed. Do someone have a good idea to filter the combo box when detect a duplicate data and just showing one of each company only? or can i create a query with just listing one of each company from the table with all those duplicate company data?
Thank you.
Regard,
alex

Hello All, I am looking for any advice on the following dilemma. I have a table with new monetary transactions that come in every day. I would like to have the transactions(one debit and one credit) that net to zero eliminated from the table automatically. What I was thinking was to have an abs amount column added and run the duplicates query as a delete query based on this column, but that would not only eliminate the amounts that net to zero...but similar debit and credit amounts. Does anyone have any thoughts on the most efficient way to do this? Im sure the answer is staring at me in the face, but I cant get my head around it. Thanks in advance!

I am trying to figure out a logical WHERE condition. I have a Query that gives me data,
Code:
Name | Start | End
--------+-----------------+-------------
Paul | 30-May-15 |
Eugin | 21-May-15 | 28-May-15
Francis | 04-Mar-15 | 08-May-15
Samuel | 10-May-15 | 13-May-15
I want to have only Paul and Francis. As Eugin start is 21-05-2015 and End is the same month, so is Samuel's. So I want to eliminate those two records.I have checked pbaldy's web of overlapping records. But unlike that, I need something customised.
Begins and ends before range - we don't want - Yes
Begins before, ends during - we want this one - Yes
Begins and ends during - we want this one too - NO
Begins during and ends after - we also want this one - Yes
Begins and ends after - we don't want this one - Yes
Begins before and ends after - we want this one -NO

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.

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

(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

I have two tables, and I made a union query (tbl1 UNION ALL SELECT ...tbl2). Problem is, I have two entries that are identical in both tbl1 and tbl2, but I want to include BOTH of them in the union query. Even though I used the ALL operator, only one set shows up!! I'm pulling out my hair trying to figure this out. Please help, and thanks so much in advance!:(

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.

Why I am getting duplicate results for some of my records in a query. I have unique values set to Yes. I have also validated that the tables I am using don't have duplicate data. SQL is below.
SELECT DISTINCT [tbl_Rewards Activity Report - By Member Number].[Member Number],
[tbl_Rewards Activity Report - By Member Number].[Last Four],
[tbl_Rewards Activity Report - By Member Number].[BAL ID],
[tbl_Rewards Activity Report - By Member Number].[Primary Name],

I have this small database, I would like to have your support to setup this query "QryResults" in order to remove the duplicate records, I can't find a way to get shown only true records, for some reason I'm getting duplicate rows and fake values, the query is calculating operations from two different queries and a table.

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

I'm trying to duplicate the records in a subform to a new form but keep getting a too few parameters error.
Code:
strSql = "INSERT INTO [OrderDetailT] ( OrderID, ProductID, Quantity, DiscountPercentage ) " & _
"SELECT " & lngID & " As NewOrderID, ProductID, Quantity, DiscountPercentage " & _
"FROM [OrderDetailT] WHERE OrderNumber = " & Me.OrderNumber & ";"
The debug.print comes out as below:
INSERT INTO [OrderDetailT] ( OrderID, ProductID, Quantity, DiscountPercentage ) SELECT 49 As NewOrderID, ProductID, Quantity, DiscountPercentage FROM [OrderDetailT] WHERE OrderT!OrderNumber = 11;

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).

I have a query with a calculated field as follows: Age: (Now()-[DOB])/365
Even though I have set the property sheet to '0' decimal places, the results are showing about nine decimal places. Is there a way I can get it to just show the age in years without all the decimal places? I'm pretty new to DB and have seen a couple of postings, but couldn't understand how to apply them to this simple situation.
Many thanks
Mohani

I trying to change empty values in a query/Table to zeros so that I can use them in calculations.
I try to use the Nz function and the IsNull function but both give me the same result: "Compile Error" when I try to switch from design view to datasheet view.
This is what I put in a field: 'Expr1: nz([cancelamount],0)'
(IsNull has he same effect).
I went to multiple sites and this is how they explain the function should look like.
My question is:
do I have to enable something to use this function?
Am I typing it in wrong?

I get a negative value when i run the below expression.
The expression picks the month from the field txtmonth in form "frmYearToMonth" and search's the crosstab query "ctbYearToMonth" for the corresponding value in txtMonth.
=DLookUp([Forms]![frmYearToMonth]![txtMonth].[Value],"ctbYearToMonth","")
The value is correct but there is a negative sign before the value how do i eliminate the negative sign.

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.

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?

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').

Hi
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
