Removing Duplicates From Dataset

Dec 12, 2011

I have data that I want to combine. However the separate data sets have some duplicates.

Let's say it is Customer Num field.

What I am saying is I am trying to combine the data sets to make a table with Customer Num and Customer Name.

I want to eliminate the duplicates. What is the best way to do this? Is there a feature in Access for this?

Removing Duplicates From A Query

Aug 14, 2006

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

Removing Duplicates From A Table

Aug 19, 2004

Hi,

I'm running MS Access (2002 SP-2)

I have a table that has the following columns in it:

Sent NBR (text) / Sent Date (date/time) / PIC (text)

It's a customer listing of our customers and which long distance carrier they have selected. Unfortunately my data also shows OLD customers that no longer own that phone number. Because of this, various phone numbers are listed numerous times, but only the Sent NBR with the most current Sent Date is the one I need to see. The others are irrelevant and need to be deleted. I'd manually delete the duplicated Rows but I have over 115,000 duplicates!!


Do you guy know of a way to eliminated the duplicates for each Sent NBR and only show me the Sent NBR's with the Most current date?

Any help would be greatly appreciated!

Merging And Removing Duplicates

Aug 9, 2013

I have a table with few Employee ID re-appearing over and over again for two different job status.

Data Example

EMP ID Job Code Emp Name Country Job Status Time Spent (In Hrs)
222 9250 XYZ ABC Complete 6
222 1059 XYZ ABC InComplete 12
222 5050 XYZ ABC Complete 7
222 1050 XYZ ABC InComplete 9
111 2750 MNM IJK Complete 2
111 2150 MNM IJK InComplete 3
111 6550 MNM IJK Complete 7
111 8250 MNM IJK InComplete 9

I need an output which merges the data based on Emp ID, however, adds the time spent for completed and incompleted job status in 2 rows.

Output Requirement:

EMP ID Emp Name Country Job Status Time Spent (In Hrs)
222 XYZ ABC Complete 13
222 XYZ ABC InComplete 21
111 MNM IJK Complete 9
111 MNM IJK InComplete 12

Which query to use? I use Access 2010.

Removing Duplicates While Keeping A Running Total

May 10, 2005

High everyone I've had a look around the FAQ's and other threads but haven't been able to find what I'm looking for.

I have a table that contains two fields, one being 'part number' and the other being 'quantity'. Unfortunately there are multiple duplicate 'part numbers'. I am looking at keeping only one instance of the duplicate 'part numbers' but at the same time I want to add the 'quantities' together to keep a running total.

For example:

Before
Part Number Quantity
a1 1
a2 2
a3 2
a1 1
a2 1
a1 4
a1 1

After
Part Number Quantity
a1 7
a2 3
a3 2

Any help would be greatly appreciated.
Cheers

Access 97 - Query Help - Newbie - Removing Duplicates

Jan 25, 2007

Hi,

just finding my way in Access 97 with no real support. I have made a query that creates duplicate records when I only need to see one for a certain criteria (lets say criteria X). This is due to the data feed involved in making the query where criteria X is found in numerous records.

What I want to display is only one record per entry containing an exact match for criteria X.

Finding it hard to articulate this but I would need something that defines:

If criteria X is the same, just display one record.

Hope this is somehow clear as I am struggling a bit. Would be gratefull of some help.

Thanks

Forms :: Removing Duplicates From Drop Down List

Jun 17, 2013

I have created a database which is used as a sign in and out machine for students. I have 2 forms a 'sign in' which has a lookup list containing all student names. as well as date and time and a 'sign out form' which uses a lookup list from the sign in form.

It collects data fine but when a student signs in and out a second time there name is duplicated in the 'sign out' drop down list. The student must select the right name out of the duplicates otherwise it wont record.

Im just wondering if there is some sort of fix to this.

Modules & VBA :: Edit Dataset Works And Add A New One

Aug 4, 2013

I have an edit button in my form which activates VBA, collects all data from the fields and edit the dataset. Everything work fine except the case that next to the edit access adds a new record as well with exactly the same data.

This is my code :

Dim db As Database
Dim rs As Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("select * from tbllocations where locationid = " & cdkey)

[code]...

I checked every parameter and it seems everything is OK which surely is the base for the correct edit of the dataset. locationid is the key of the table.

Query To Add Empty Records To Dataset?

Jul 31, 2014

I have a dataset showing sales by salesperson for each product. I'd like to summarize this data in a table that looks like this:

Note that some salespeople don't sell certain products and that these records show up with "0". My problem is that, in my actual dataset, if a salesperson doesn't sell a product, that records doesn't exist at all. Is there any way to append empty "0" records to my dataset? See attached for an Access file.

Queries :: Dataset - Group By Query Without Summing

Jan 15, 2015

I have a a dataset that has recorded encounters with a number of Banded (identified) animals. It is currently setup so that each encounter is its own row; with all the information, including "Band_Num" repeated, but "Encounter_Date" being unique. I wanted to query the table and get it to display the results as "Band_Num" on a row, followed by x columns for with each unique "Encounter_Date" represented. I thought a "Group By" function would work, but that requires a sum, which is not useful.

Complicating this is the fact that not every individual is seen a set number of times, so Animal 1 might be seen 3 different dates, but Animal 2 only on 1 date.

Forms :: Uneditable Dataset In A Subordinate Form?

Jul 16, 2014

I've got a form with a combo box where I choose an employee and according to that employee's attributes are shown. Some of the attributes are stored in the same table with employee names, some of it is connected by foreign key to other tables. This form is not editable, information only. I've got a button "Edit employee" which opens another form intended to edit the information. I put text fields there by dragging the fields from tables. And so, for some reason, the only editable fields in that form are those connected by foreign key to the main table, but the main table fields are all not editable and error "not in dataset" comes up.

General :: Random Selection From Large Dataset

Jun 25, 2013

I pulled a report from this website my company uses and it has around 7,000 orders and a corresponding employee to each record. Since each employee has around 20-50 orders, I was wondering if there was a VBA code or different Access tool to randomly select only 2 orders from each employee, thus reducing the data set from 7,000 to a more manageable number?

How To Show Field Content In A Label - ID Of Dataset

May 24, 2012

I want to display the ID of a dataset in a form but I don't want the user to be able to edit it. Therefore I want to display the id in a label and not a textbox or combo etc.

I can't see a way of how to do this though. Is this possible, or am I going about it the wrong way?

Queries :: How To Handle Empty Dataset As Form Recordsource

May 7, 2013

In Access 2010, I'm writing VBA code that assigns an ADO dataset as the recordsource for a form. The query itself varies and is constructed from a search term typed in a textbox by the user. The code below works perfectly until the dataset is empty, when no records satisfied the WHERE criteria. In that case, there is a very long pause (presumably a timeout?) and I eventually get the error message "ODBC call failed." I tried to get around this by testing the number of records in the dataset (see toward the end) before assigning it, but it makes no difference in the behavior, so I'm thinking the actual assignment isn't the issue ... something else is.

If it matters, the "FROM qry_beneficial_owners" in this case is predefined query local to my Access db. That query is based on a linked view from a SQL server.

Code:
Public Sub RunSearch(SearchTerm As String)
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim sql As String
Dim cols As String
cols = "[acct], [acctname], [planid]"

[Code] ....

Forms :: Quick Print Printing Previous Dataset

Jun 6, 2013

I'm having an odd problem with a form. We noticed this since migrating it from adp to accdb.

It's a form with two subforms in datasheet view, that contain data on a certain employee, which is selected on the main form.

If you use print preview before printing, it all prints out fine. However, if you use quick print, it does something weird. If you Pull up Employee A, then Employee B, and do a quick print, it will print the data for Employee A in subform 1, and the data for Employee B in subform 2. It displays correctly on the screen though, and the 2nd time you quick print, it comes out right.

Find Duplicates Different Than Duplicates Deleted

Dec 8, 2005

Hey, all! Thanks for helping, here is my situation.

I have a table with about 70,000 records that have duplicate Address field values. The rest of the field values for those records are different. When I do a find duplicate querry I get the result that 17,000 records have the same address. However, when I do the append qurrey as instructed here: http://support.microsoft.com/?kbid=209183 I get a total of only 600 records in the new table. I have tried deleting all of the indexes for both the new and old table, with no luck.

I'm using Access 2000 on XP Pro.

If anyone could help with this I would greatly appreciate it!

Thanks

Forms :: Dataset Based On A Table - Order Of Added Records

Aug 9, 2013

I have a form with a dataset based on a table. (there are a number of buttons on the form with code so it's important I don't delete the form and start again with a new one)

The data displays correctly but the order is wrong. It displays the last record added as the first record when viewed in form view.

I want to reverse this order, how do i go about it? It seems very simple but I've yet to find a solution.

I also don't want to base it on a query because of the code mentioned earlier.

General :: Create Dataset With Ability To Search Through Macro Form?

Feb 23, 2013

i orginally thought i should do this in excel but i think when the dataset becomes larger and i want to eventually get it on the web - i thought its access i need?

i have created a mini dataset as an exmaple of what im trying to explain..i have in first column the objects, and columns after this are the elements needed to make the object (i have just labelled the element titles a b c etc - there will be LOTS of elements once i get the dataset created). so if i had a red blue green cream elements - a search would bring back both lights and lamps that i am able to make.

object A B C D E F G H
lights red blue green cream
lamp red blue green cream
garage red blue green cream yellow brown purple pink
house orange white green blue red black
garden orange white green blue red
garden house orange white green blue red

is there a way of creating a search lookup to this kind of information? a form which you type the criteria in and it brings back what you can make? if i was one element away from an object could I use a wildcard function to say, if you had black you could make a house?? etc

General :: Combo Charts - Graph Showing Certain Dataset As Column And Average For That Set

Aug 10, 2015

Is it all possible to create the equivalent of a combo chart in Excel in Access?

What I need is a graph showing a certain dataset as columns but also a line showing the average for that set.

As an example lets take an exercise programme in a school, each child performs a series of exercises every week and data is recorded, to monitor their fitness progression.

Lets say I wanted to show a graph of one particular exercise, with the class students listed along the x axis, and then show the class average for that exercise dataset as a line on the same graph.

Modules & VBA :: Splitting Dataset Sorted On Two Fields Based On Change In Value In One Field

Feb 6, 2014

I am new to MS Access, and am not sure if what I want to do is even possible. It is my understanding that comparing subsequent cells within a field in a database cannot be done- so I thought I'd see if there is a way to go around it.

I have a dataset for pedestrian activity, with over 3 million rows and 40 columns - too big for excel to handle.

I need to sort the entire dataset by 2 fields, following which I need to search down the field containing my pedestrian ids (numbered 1, 2, 3... till approx 10000), and when my ped id changes from one to the next, I need to check the value in a field showing the ped location, and if that matches with the ped's previous location, I need to copy out a cell corresponding to the previous cell's time stamp. If it doesn't match, I need to copy out another time stamp from another field.
