Finding Unique Records Between 2 Tables

May 12, 2006

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

Finding Unique Records In A Table

Mar 25, 2015

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?

Tables :: Unique Identifier - Increment For Duplicate Records

Jul 10, 2014

I'm currently in the process of doing a an overhaul of the database including a table, some odd 17,500 records long.

What I need to do is to create a unique identifier from the existing part number, almost like an autonumber, but it only increments when there are duplicates. What I mean is that there would be for example, there would be five records of say, part 000135.

What I'm trying to get at is, how I would have to code to grab the existing part numbers (all formatted to be 6 digits), add an extra 2 digits to be its unique identifier, and then save it all to a Unique Identifier column, that I created.

An example of what I want is say, I have part numbers 000135 and 000136. The numbers would go up from 000135-01, 000135-02, 000135-03, 000136-01, 000136-02.... The dash is not as important as implementing the 2 digit unique identifier.

Finding Unique Data Using Date Field

Mar 27, 2008

Hi

I have a table called SWAPS which contains information on each user and the different equipment he has been issued. Query at the moment contains 5 fields

Payroll, Surname, Firstname, Mobile No and Date sent.

SQL for this query is as follows

Select Swaps.PR, Swaps.surname,swaps.firstname,swaps.[mobile no],Max(Swaps,[Date Sent] as Lastdate

From Swaps

Group by swaps.pr, swaps.surname,swaps.firstname,swaps.[mobile no]

Order by swaps.pr;



Now when I run this I get the results I want by date so I get



123456 Smith Fred 0788411025 12/3/8

456789 West Bob 012555447854 13/1/8

So it correctly ids all the last dates for me as I want to see the latest issue date for that user. Now I want to add in another column to this query which contains the serial number of the equipment issued and heres where the problem lies. If a user has been issued more than 1 piece of kit, I get all the serial numbers irrespective of date. How do I get it to display the serial number for the latest date?

Thanks

Finding Sequence Of Fields Making A Unique Record

Aug 23, 2006

I have a MS Access 2000 database with 136 data tables in it. What I would like to do is execute a piece of VBA code which will list for me in another table, (for example: Field1: TABLE NAME Field2: FIELD NAME 1 Field2: FIELD NAME2 etc), starting left to right, how many fields would have to be combined in each table to represent a unique record.

For instance:

TYPE ID TEXT
1 1 "Cats"
1 2 "Dogs"
2 1 "Rabbits"

In this example a combination of the fields TYPE and ID give a unique record.

Any help most appreciated.

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

Finding Records Between Dates

Jan 4, 2005

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?

How to do this but I do have a query/report that will subtotal based on the LOC-RC field.

Finding Records With Empty Field

Jul 18, 2007

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.

Queries :: Finding Records Between Dates?

Jun 4, 2013

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..

Forms :: Finding Records In Subforms

Apr 28, 2015

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?

Query Not Finding All The Correct Unmatched Records

Mar 31, 2006

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.

Finding Records Based On Text Inputs

Sep 13, 2005

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.
