Finding Duplicate Records
Jun 19, 2006
Hello
I've had to export data from an old third party database to Access with the task of reporting on the data. I have a client table and work tables, one for each year going back to 1992. In the original database, the clients do not have a date of when they were set up. I need to find out how long clients have been with us, so I thought of going back through the work tables 2006 to 1992 and finding out where they first occurred, by looking for duplicate records in the tables. Is this a simple enough thing to do? The client table and work tables are linked through the field Client.
Thanks
Dave, England

Hi
This is my first post and i searched to try and find an answer on the forums but can't seem to find one so thought i'd ask to see if anyone is able to help. Sorry if this has been answered before and i've been a bit thick not been able to find it. anyway here's my question...
I have 2 fields i want to check in my database DOB1 and DOB2 (date of birth of applicant 1 and date of birth of applicant 2.
i've written a query that looks for any records where the data in DOB1 and DOB2 match the data in another record for DOB1 and DOB2. i hope that makes sense. this is what i've written.
In (SELECT [App1 DOB] FROM [Data] As Tmp GROUP BY [App1 DOB],[App2 DOB] HAVING Count(*)>1 And [App2 DOB] = [Data].[App2 DOB])
this seems to work but please feel free to correct me.
Now the part i'm struggling with is trying to find duplicates where the fields have been reversed. eg App1 DOB and App2 DOB are the same as App1 DOB and App2 DOB in another record but applicant 1's Date of birth has been stored as Applicant 2 and Applicant 2 is now stored as Applicant 1. i hope thats not to confusing.
Basically i'm trying to check for duplicate mortgage applications in the database but sometimes applicant 1 and applicant 2 are reversed.
Any help would be greatly appreciated.
Thanks

I am trying to find duplicate data from two columns and I want to query the all the duplicates. I tried the query wizard but it only finds duplicates in the column itself. I am trying to compare the columns together and see what is found in column A that is also found in column B and also Vice Versa.

Can't think how I would do this. If I create a query with a certain date then it will need to be changed every time the query is run. How would I write a query that automatically looks for a date 3 months or more old.
Thanks for any help. :D

I have a table, and there are many records, each with a unique value in the OrderNumber field
I have a text box on a form, and i want it to work so that the user types in a OrderNumber value, and it loads that record into the form (the form is bound to the table)
I already know how to load a record by record number, but how can i do it by OrderNumber value?
thanks

Hello, i need to have my database find records that were entered between two dates. To do this i made a query that included the dates the records needed to be in between....[date1] and [date2]. Then i had the record dates be called [sent date]. i made my query and in the criteria for [sent date] i wrote
(Between [Date1] And [Date2])
when i enter the two dates [date1] and [date2] the query does not show the records that are between that date. why is this happening? is there and easier way? another way?
For example, say that i have records with their [sent dates] equaling 12/30/2004, 1/1/2005, 10/1/2005
i want to make it so that when the user inputs a records with dates [date1] and [date2], that those records will show up if their [sent dates] are between [date1] and [date2]. if [date1] is 1/1/2003 and [date2] is 1/1/2006, all of the records will show up.
if [date1] is 12/31/2004 and [date2] is 1/3/2005, then only the record with the date 1/1/2005 will show up.
how can i do this?

It's combining data from 2 system Identified by E or L. The data is similar but not exact & I'm comparing it using the description. What I need Access to do is find the record that doesn't "zero-out". In the example above the record it should pull is the last one "Kroger $389.74". How to do this but I do have a query/report that will subtotal based on the LOC-RC field.

Dear all,
Many thanks for taking the time to read this.
I have a slight problem which seems like it should be easy to solve but I have no idea how to do it.
I have 2 tables (table1 and table2 for instance) Table2 contains more data than table1 but should contain everything in table1 as well as more.
How is it possible to return just records that are in table2 that are not in table1
Eg
Table1 contains:
IDab
112
222
322
422
511
611
711
Table2 contains:
IDab
112
222
322
422
511
611
711
833
The query should return just the line:
833
as this is unique.
thanks again

The last field in my table is 'Comments'. I want to find if any record or records with 'Comments' field empty. I created a query and added all fields from my table. In the criteria section I typed Like "null". But the query is not returning records where 'Comments' field is empty. I have deliberately added (for testing) a few records leaving comments field empty. This can be viewed clearly in Table view. But the query I made is not displaying the records. Please help.

I have a table tbl_PolicyDetails with details of the policy the customers have with us.. In the tbl_PolicyDetails, I have two fields (these are the ones in question) called
"policyStarted" - Start Date of a Policy and
"policyPeriod" - Term of Policy Monthly/Annually/Quarterly
So in a Form view I just get the Next installment for the customer based on this information for display.. For example..
Mr Butters Stotch's policy started on 26/04/2013 and is paying Quarterly; the next (i.e. 2nd) installment would be on 26/07/2013..
Ms Wendy Testaburger's policy started on 07/04/2013 and is paying Monthly; the next (i,e. 3rd) installment would be on 07/06/2013..
This is not hard to get.. I have that sorted.. But the problem is, my manager wants to be able to specify two dates and search all policies that will be 'paying in' that Date range should be picked up..
So if the search range happens to be.. 01/07/2013 and 31/07/2013 Then Mr Butters Stotch's policy should be picked up, as his next installment falls on 26/07/2013.. Since this information is not stored, I cannot run a direct Query on this.. Also as the Installment number varies for each customer, I would not be able to just add 1 - Month or Quarter or Annum, and see if the date falls in that range..

I am working on MS Access 2010 and have come across a bit complex situation. I have a table with about 20 fields. In a main form, I have added 4 sub-forms where each sub-form is showing 5 fields of each record from the table. This is because of step by step data entry into the same record. I have made these sub-forms as "Continuous Forms" and have given them look of Data Sheet.
There are about 1000 records currently present in the table and these are showing in my sub-forms (5 fields each). Now the problem is that, when I have my Focus on one record in my first sub-form to enter some data, and then I click on second tab of sub-form, the same records should be shown in second sub-form as well. Currently it is not being happening and I have to scroll down my second sub-form to search that particular record. It will become much more difficult when number of records will increase.
How can I work it around and get my cursor on the same record on every sub-form?

My DCount statement is not finding a record that I know is there.
Code:

ST = "H"
If DCount("*", "Books", Author = " & Me!AuthorID & " And StatFlag = " & ST & ") > 0 Then
DoCmd.Beep
End If
End Sub
It never beeps!

I have one table with 250 fields and hundreds of records. Each field represents a computer we have and the records in that field represent the type of applications we have on that computer. So the table looks like this:
Computer 1..........Computer 2.......... Computer 3........ Computer 250
Microsoft...............Google.................... .Paint.....................Microsoft
Windows Hotfix......Security Updates.......Java ......................Google
Java.....................Mediaplayer.............. Google.....................Java
As you can see, most computers have the same applications, but some have applications that others do not. I just need the list of applications we have from all computers. Meaning each app is listed only once.
I just need each application listed once. So I was trying to come up with a way to delete all the duplicates or use a Totals query to group the apps but since my table has 250 columns I'm not really sure how to go about it. What kind of query would be best to make this work?

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 several tables that I am trying to get information from:
Clock Number Table with fields: Clock #, Name, Title, Dept, Term, HireDate, & TransDate.
Completed Training with fields: Clock #, Data Completed, Doc # & Rev Level
Linked Table, Controlled Documents with fields: Doc #, Title, Effective Date & Rev Level
Linked Table, Distribution Table with fields: Doc #, Distribution, Rev Level & Effective Date.
Some of the tables have more fields that those listed, but they do not pertain to this query.
I am trying to create queries that will provide me with the names of employees who have not been trained on Controlled Documents that have been distributed to their department.
So far, I have been able to determine if no one has been trained, but if even one person has been trained, they do not appear on my list. I would like to know the Clock # and name of those that have not been trained.
I have created 3 queries to get this far. Query 1 is the Clock # Table and the Completed Training Table joining the Clock #. Query 2 is the Controlled Document Table and the Distribution Table joining the Doc #, Rev Level. Query 3 takes these queries and joins Doc # and Rev Level. and pulls records where the Rev. Level and Doc # is Null.

Hello
I am trying to set up a user friendly front end to my database. I would like to have a form which allows the user to enter information into text boxes and then press a button which finds the relevant record(s).
I would like to use it to pin point an employee's record based on at least one piece of information, but possibly combined with up to four more by entering into these boxes. For example personnel number, surname, first name etc.
Is this possible and how do I go about setting it up?
I am aware of the filter function and queries but I can't seem to get either to operate in the way I have envisaged. They don't appear to offer the most user friendly solution, at least not in the format I have tried.
Apologies, but I am still getting to grips with access to be honest.

Let's say it found 5 records matching the search criteria.
I like the Access form show me each record every on second. Meaning show me next record every one second.
I have the follwoing code to loop throgh each record but I nned to run after the find code runs and loops throgh the record that have been found:
I have the following code to do the loop through each record but, I need to run it after running the find code and then loops through the records that have been found:
Code:Private Sub Command10_Click()Dim inti As Integer'Loop through record 1 to 20 in form For inti = 1 To 20 DoCmd.OpenForm "DEM_RECH_CHECK_LIST", , , "[household_id]= " & inti Next inti End Sub
I need some help to combine the above codes.
Thanks in advances,
Abrahim
