Merge Duplicate Values With Unique ID
Feb 28, 2014
I have a query with over 85,000 lines of data where each row has a unique id but the unique id appears multiple times within the table. For example, there is a unique numeric id tide to various types of pets across four columns. So the id number 1 could appear in four different rows each with different pets. Please see the first attachment "Original Table"
I want to be able to create a table that has one for for each unique id with all of the corresponding pet data. Please see the attached "Desired Table".

1. I have a database (see attached) with three tables all of them with the same fields. The first three are numbers (InCo_No, Proto_No, Year_No). Each of these fields (numbers) can be the same in the other table(eg. Year_No), but the combination of the three cannot be.
How can I prevent the entry of a duplicate combination of these three fields?
2. I want to have a form to fill the three tables separately, depending the values in the other fields.
How can I do this?

As mentioned before on a different topic I am building a database to sort through publication authors. I currently have the table sorted in a way that only the main author is listed for the 3000 records. Now I need a way to remove duplicate entries on a new table. Each entry is a different publication. Each record has a DOI code that is unique and an author which might be a duplicate. I want a new table listed by author once and a new field that list all of the DOI numbers for that author.
I know how to do a query to show only the unique names, but how to I also get the database to combine the records that share the same author.?

I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?
So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.
If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.
For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.
So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.
There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.
A few notes.
1.Getting as close as possible to the requested number is a requirement.
2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).
my table (NR_PVO_120)
Row OtherID Fax
1 11098554 2063504752
2 56200936 2080906666
3 11098554 7182160901
4 25138850 7182160901
5 56148974 7182232046
6 56530104 7182234134
[code]....
A few sample outputs
one solution is taking rows 1-6 and 26.
OtherID
11098554
56200936
25138850
56148974
56530104
56148975
Another solution is taking rows 1-4 and 10-14.
OtherID
11098554
56200936
25138850
56024315
56115247

This is for a fax campaign, we need to make sure no fax number is faxed twice, that all people connected to that fax number are contacted under one fax sent.

We are working on an Access (2007) database that is on a SharePoint Site (2007).
Currently the form is operational, but there is one last thing that would be nice to have.
The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.
In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.
All data is currently bound, so once the user makes a change it is made, no submit button is required.
We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.
TABLE - UPDATED HEADCOUNT
COLUMN in UPDATED HEADCOUNT - EMPID
FORM CELL user will input an EMPID - newEMPID
FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID
So below is what we are trying to do, we are sure there are a few commands missing....
=IIF(newEMPID=dlookup([UPDATED HEADCOUNT]![EMPID]), newEMPID, "Error, EMPID already exists")

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.

Is there a way to merge duplicate/similar Access 2010 records into one record?
I have an Access table with 1,000 duplicate records, although they are similar and not exact duplicates. As you can see below, some records contain information that other records do not. Yet, the primary key is the same for all duplicate records. I want to find a way to merge data from filled cells of duplicate records into empty cells for each duplicate record. I do not want to concatenate the data (i.e. combine last and first name, etc.). I only want to fill empty cells if there is a match for it in a duplicate record. I will delete the newly exact duplicate records later. Short of correcting the records by hand.
Example
Code:
LastName FirstName SSN Address Phone Email
Doe John 123-45-7891 123 Anywhere St. NULL john(at)gmail.com
Doe John 123-45-7891 NULL (123)456-7890 NULL
Desired Result
Code:
LastName FirstName SSN Address Phone Email
Doe John 123-45-7891 123 Anywhere St. (123)456-7890 john(at)gmail.com
Doe John 123-45-7891 123 Anywhere St. (123)456-7890 john(at)gmail.com

Currently am trying to get together two separate Access Databases into one, which is the way it was always supposed to be.
Basically, this person accidentally created a duplicate of the database in question, and has been updating both independently at different times, meaning that whilst a lot of the database information is duplicate, there are some instances where each separate database copy has unique information on both existing contacts, and new unique contacts.
The database itself is about schools, and has tables concerning information such as calls made, contact details, school details, etc etc. Obviously all of this needs putting back together into one set of tables in one file.
I've been messing around with append and import functions, but am having issues with duplicate ID fields with append queries, and a general lack of direction on the best way to go about fixing this problem, if its even possible.
Here's an example of what i've been trying to do:
INSERT INTO Contacts ( ContactID, ContactTitle, Name, Surname, JobTitle, TelephoneSTD, Telephone, FaxSTD, Fax, Locale, SubjectKeyword, SchoolID, Reply received] )
SELECT [1Contacts].*, [1Contacts].ContactID, [1Contacts].ContactTitle, [1Contacts].Name, [1Contacts].Surname, [1Contacts].JobTitle, [1Contacts].TelephoneSTD, [1Contacts].Telephone, [1Contacts].FaxSTD, [1Contacts].Fax, [1Contacts].Locale, [1Contacts].SubjectKeyword, [1Contacts].SchoolID, [1Contacts].[Reply received]
FROM 1Contacts;

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').

I have a query that has an Item, ItemPrice, Allocation, and DatePurchased ordered by DatePurchased with only unique values.
I'm using it for a PO Database, when entering items purchased, I have the Item field populated with a items previously purchased, when the item is selected the Unit Price and Allocation Fields are autofilled in with the most recent values from the PO details table.
My problem is if I purchase 10 of the same Items on 10 different dates then the combo box will show 10 of the same Items, because they are not unique values because of the DatePurchased.
What I want is a query to show one unique Item entry with the most recent Purchase Price. I can get a list of unique Items, by only making a query of those and showing only unique values, but as soon as the date is introduced it no longer works, for obvious reasons.
Any help appreciated,
JOe K.

I have a database to track client activity per session.
Each client has a unique client number but multiple activities.
Therefore, if I have 20 clients in the database and each has 3 activities, I have 60 client numbers, 3 *20 = 60. ( Duplicated)
My elementary problem is how do I display the client activity unduplicated so that my query returns only 1 unique client number per session.
I tried the unique records/values in the property box but still.....
Thanks for your help.

Hi,
I have a situation and i do not know how to handle it.
I am developing an application for a lawyer. In the data base i have the following tables: Files, the people table (that are involved in a lawsuit), and other tables. The problem is the following: in the people table, beside the primary key i have another unique element that is social security number.
In the files table beside the primary key another unique element exists: the number and date of the file (File 1 from 15.02.2006). A lawsuit file can have more law terms: today it has one law term and maybe next week another law term so i must have the same file many times in the table with the same code and another date, but i cannot add the same file many times in the data base because a file has data about one person and the social security number of the person is unique.
If anyone can offer me a solution it would be good.
Thank you!

Hi guys,
I've tried searching all the threads for an answer to my problem and I can't seem to find it....
Ok I know this should be simple...
I know to use Distinct and DistinctRow to only show unique records in a combobox but all I want to do is that once a selection is chosen in the combobox to add a record to a subform, it can't be selected again.
I know in some cases you do, e.g. items on an invoice sometimes need to be entered more than once, but I'm listing Skills for Employees and I only want a user to enter a Skill once per Employee (although Employees can have many Skills, I just don't want a User to accidentally put the same Skill in twice or more per Employee...)...
What's the best optimized way of achieving this?
Sorry for my newbiness.

I have the following SQL definition:
SELECT DISTINCT tblFile_Management_Received.Claim_Number, tblFile_Management_Received.Date_Checked_In, tblFile_Management_Received.Checked_In_By, tblFile_Management_Received.Copy_or_Original
FROM tblFile_Management_Received;
The results would show as:
ClaimNumber Date Checked In Checked In By Original or Copy
111111111 2/16/2005 8:34:24 AM XXXX Yes
111111111 2/16/2005 1:23:19 PM XXXX Yes

222222222 2/16/2005 1:24:49 PM XXXX Yes
I am trying to use "Distinct" to show the following records when the query is ran (the desired results would be each unique claim number based on the earliest check in date):
ClaimNumber Date Checked In Checked In By Original or Copy
111111111 2/16/2005 8:34:24 AM XXXX Yes
222222222 2/16/2005 8:34:52 AM XXXX Yes
Can anyone help me with this??

I want to have a cleaned up acces file where each ID only appears once but where the amounts are add up.
For example:

I would like to sum up choices made by a user. I'm not sure whether I should create a new table and a couple of fields (not including primary key) with Fruit & Fruit Value.
Where: Apple (Y or N)=4 or 0, Oranges (Y/N)=3/0, Bananas (Y/N)=2/0, etc. As the user chooses the fruit, the value rises.
For example, if the user selected Yes for APPLE and ORANGES the sum is 7-- or if the user selected ORANGES and BANANAS the sum is 5, etc.
Is it possible?

I don't know if I'm going about this problem correctly. In a nutshell:
I have a table which contains a number of fields, only a two of which are important for this task, as indicated below.
| ID | Type |
Where ID is an alpha-numeric identifier (say a store number), and there are three potential types, plus Null values. For this, we'll assume the three types are Fruit, Vegetable, and Grain (plus Null).
An example dataset might look like:
0-4 Vegetable
1-2
0-1 Grain
1-2 Fruit
0-4 Vegetable
1-2 Vegetable
0-1
0-2 Fruit
0-4 Grain
1-2 Fruit
0-4
0-1 Vegetable
0-3 Fruit
If I want to know how many stores have Vegetable, I could put "Vegetable" as the criteria in the query and set UniqueValues to Yes. Then I would get three unique values, one for each Vegetable existing at a unique store.
But, what if I want to know at which stores Fruit exists and Vegetable DOES NOT. Is there a way within Access to find all the records with "Fruit" as the criteria and then eliminate those with ID numbers matching the dataset with "Vegetable" as the criteria?
In other words, if I do my "Vegetable" criteria I end up with the resulting dataset:
0-4 Vegetable
1-2 Vegetable
0-1 Vegetable
If I then use "Fruit" as my criteria, I get the following dataset:
1-2 Fruit
0-2 Fruit
0-3 Fruit
Since Store 1-2 has Vegetable, I want to eliminate it from the list so that my resultant list is:
0-2 Fruit
0-3 Fruit
Is that possible?
Sorry for the long bizarre example, but I thought it the easiest way to make the situation clear. I'd really appreciate any suggestions anyone has on dealing with this situation!!
Thanks

Here's my situation...
I'm making a query that uses information on company members from a database. The most important data field is the MemberID. Many members are listed in the table more than once because different records are put in when they have more than one contact person or health plan, etc.... However, right now I am trying to have the query make a table that produces only one record for each company so I can get a total number of companies. Therefore, I dont want the query to produce records with duplicates of the MemberID. My problem is that by setting Unique Values to 'Yes' doesn't work because if a different field in the record is different, it makes the record unique. I can't figure out a way to make it so only one field is considered for unique values. The funny thing is that it is simple to do this in Excel, you just gotta go to advanced filters. Does anybody know how to do this in Access?? Thanks.

Hey guys, I'm relatively new to Access and I need some help building a query. So I work with a website that handles credit card transactions, and we keep a log of activity ie. NameOnCard, Date, Status. About once a month or so, I do an audit to make sure that all the attempted transactions are successful. Sometimes the server needs to restart, or the users computer has a problem, etc. Typically, someone who's had a failed attempt will have a successful attempt minutes or seconds later, so the NameOnCard is exactly the same, but the Date and Status are different. Right now I've created a query that look for failed attempts and one that looks for successful attempts, but what i want is one that returns only people with failed attempts that don't also have a successful attempt. Everything I've thought should work hasn't. Filtering for unique values doesn't help, because each row is slightly different, and the NameOnCard isn't the primary key. I recently tried this as a column with this in the field value:Success: IIf([Online Gift Errors]![NameOnCard]=[Online Gift Successes]![NameOnCard],"Success","Failure")(NOTE:Online Gift Errors and Online Gift Successes are queries, not tables)But when I try to run the query it thinks [Online Gift Errors]![NameOnCard] is a parametric value and asks for an input. What can I do? Should I be trying something else entirely?

This may be a simplistic question but I'm having some diffuculty figuring it out. I have multiple rows of data where I need to use the "Unique Values" property in my query to limit only what I need. However, I have a "time" field and their are similar times on different records. So say I have a 100 records but 8 of them have the same "time" value, how can I use someting like the "Unique Values" property to get my rows down from several hundred to 100, but not lose the 8 similar rows and end up with 92 rows, when I have to turn around and sum these times and need all the times to be there?
Maybe I'm approaching it the wrong way and should be doing a SUM of "times" to begin with for that field, but I'm not being able to get that to work either. Any suggestions? /Thanks
