Queries :: Find Duplicates From 2 Tables And Remove From 1 Table
Jun 29, 2014
I have a report with 2 access tables (1 Master table and another a daily feed table)
The Master table keeps a log of all incoming records. (once append it to this table, should not show in future reporting)
The Daily feed information within the last 48 hours. (uploaded from an excel report into access temporary table)
When the daily feed table gets completed, I append the records and updated them into the Master to avoid duplication.
When I upload the daily feed table and I match it against the Master table to find duplicates, how can I delete the duplicates from the Daily Feed table?
This is my code to find duplicates:
SELECT CMPreport.ID, CMPreport.MbrName, tblMaster.ID
FROM CMPreport LEFT JOIN tblMaster ON CMPreport.ID = tblMaster.ID
WHERE (((tblMaster.ID) Is Not Null));
I have a table called Stock Levels which contains 3 fields. (ID, ProductID, StockLevel) ID is the Pkey, ProductID contains duplicates and StockLevel which contains different stock levels
and I am trying to remove the duplicates and retain the the data so I am left with the correct stock number
what I have done is the following, but I am still getting duplicate values in productid and stocklevels
SELECT DISTINCTROW id, productid, stocklevel into mynewtable from stocklevels
I know there is no more than 4 dups of each record.
what i want from this is a table that will give me a record of how many dups for each record then all the dates that they were added and the date between each record entry.
I have 4 or 5 tables. Most of the fields are exactly the name but they all have at least 1 to possibly 5 or six fields that are not in the other table. Additionally there are some duplicates within the individual tables as well as across tables.
i.e.
I have a
Student Table - with all the info on the student as well as a column called student that identifies them as such however it does not have the columns parent, donor, appeal, designation..... Parent Table - with all the info on the student as well as a column called parent that identifies them as such however it does not have the columns student, donor, appeal, designation..... Donor Table - with all the info on the student as well as a column called donor that identifies them as such however it does not have the columns student, parent, appeal, designation..... Appeal Table - with all the info on the student as well as a column called appeal that identifies them as such however it does not have the columns student, parent, donor, designation.....
-A person can be within one of these tables more than once but with all the same information. -A person can also fall into all of these parameters so they could be on every table with the same information in addition to the missing columns,=.
Question 1 : what is the best way to dedupe and delete the individual tables (they all have account numbers) Question 2: I was thinking create a new table with all the columns available, however how do i dedupe across tables while populating the additional columns from each?
I have a large table with many fields and many rows. There is no primary key. I'll call one field ParentPN, and another field ChildPN. There are many other fields as well. I want to identify all rows where BOTH the ParentPN and ChildPN occur more than once. I know how to create a query to identify duplicates of ONE field in the table, but not two. I can solve this with VBA: I will read the two fields of interest in the first row, then compare both values with every other row. If it finds another row with BOTH ParentPN and ChildPN identical with the first, that's a "hit". Then, repeat with all the other rows. I could find ways to make this run faster, but I was wondering if there are any build in functions to accomplish this. I looked at the Find Duplicates query builder, and all I see is I can select ONE field to search for dupes, not two.
I have a query which gets information from 2x tables where the I'd on one table is the reference number on the second table.I would like to know how I can remove the duplicates on my reference number field?
Employees submit information into a form which translates the information into a table. The table has been in use for years. By accident some employees were writing to an archived table while others were writing the the active table. This resulted in a field called "WorkID" being duplicated across the two tables.
Bottom line I am trying to write a query finding duplicates across tables but basing the duplicate only on certain columns.
I have a find duplicates query with the following SQL:
Code: SELECT tblData.Vendor, tblData.[Loccurramount EUE], tblData.Last4, tblData.ID, tblData.Line, tblData.CoCd, tblData.[Document record number], tblData.PurchDoc, tblData.Reference, tblData.Curr, tblData.[Entry dte], tblData.Status, tblData.Version, tblData.Outcome FROM tblData WHERE (((tblData.Vendor) In (SELECT [Vendor] FROM [tblData] As Tmp GROUP BY [Vendor],[Loccurramount EUE],[Last4] HAVING Count(*)>1 And [Loccurramount EUE] = [tblData].[Loccurramount EUE] And [Last4] = [tblData].[Last4]))) ORDER BY tblData.Vendor, tblData.[Loccurramount EUE], tblData.Last4;
This works fine however I want to add another clause to the WHERE and I'm not sure how. At the moment the query highlights duplicates where the Vendor, Loccurramount EUE and Last4 match. I want to further restrict it so that it only finds duplicates where the Vendor, Loccurramount EUE and Last4 match BUT the number shown in version Does Not Match
So if two records have the same details for Vendor, Loccurramount EUE and Last4 and also have the same Version number then they don't show in the result.
I used the wizard to create a find duplicates query. I know for a fact that 15 records are duplicates. I'm getting over 300 records. When I dumped the data into Excel and did a pivot table to count the number of records by account number only 15 had a total count of 2. All others only had 1. Why are the ones with no duplicates showing? I just want to see the 15.
I have a Find Duplicates query that I created with the Query Wizard.
IF I run the query and find duplicates, I can close the resultant datasheet with the close button.
IF I run the query and find duplicates and delete them, I can close the resultant datasheet with the close button.
IF I run the query after I have found and deleted duplicates and closed the window, I can close the resultant datasheet (with no records) with the close button.
BUT IF I run the query when there are no duplicates, it opens the datasheet with no records, but you can't close it with the close button. You have to exit the database completely.
I don't know SQL or VB. Have to do this in Access.
I thought about creating an If statement in a macro, but am not sure of the syntax, but this would be the basic statement I would make:
IF Find Duplicates query returns no records, THEN Cancel Event. End IF
Access 2007 - I am using the oft used, frequently posted and shard code from srfreemen - modified as below. now I know I sort of broke commandment # 8 - Thou shalt not copy and paste other people's code without at least attempting to understand what it does. but I honestly did try to understand what it does.
I keep getting runtime error 3078 - cannot find the input table or query 'tblEnrolment_Committee_Master'. It is the name of a table in my database but I am missing the very basic element of how to get my form (which draws all of it's fields from that table) to look it up or identify it.
Likely because of a silly basic error. Normally - I wouldn't attempt such things but my work needs me to ensure no duplicates exist in this case AND it's already a primary key - but I don't want to wait until the whole form is filled out for it to identify the duplicate!
How to get the tblEnrolment_Committee_Master to be included in the search and erase this error ...
Private Sub Entitlement_File_Number_BeforeUpdate(Cancel As Integer) Dim SID As String Dim stLinkCriteria As String Dim rsc As DAO.Recordset Set rsc = Me.RecordsetClone
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!
I have a query linked to a main frame database. One of the fields is [significance] and gets a number 1-20. Usually when this data is entered, it gets multiple significance numbers. This causes my query to return separate records for each significance number. For example if case number 123 is given significance codes 1, 5 and 12, then my query returns 3 records.
I need a query that will show all records one time that have a significance code other than 12. This would be easy if there were not duplicate entries for the same case number because I could simply say "Not 12". So in the example above, my query returns 2 records showing significance codes 1 and 5. But I don't want to see the record for case number 123 because it also has a 12 significance code.
If have a table with billing occurances and one of the fields is "business name" how would I need to setup a make table query which lists unique occurances within that data?
Essentially, I want to remove duplicates. If ABC Pet Store has 5 billing occurances and XYZ Pet Store has 1... I want both to only be listed once.
I hope that makes sense. Thanks for any help as to how to set this up!
I would like to remove duplicates from the following query. I would like it to display only one record depending on the InvoiceID. So only show one unique record based on Invoices.InvoiceID. Thanks!
SELECT DISTINCT Invoices.InvoiceID, Invoices.CustomerID, InvoiceDetails.InvoiceDetailID, Invoices.InvoiceDate FROM InvoiceDetails INNER JOIN Invoices ON InvoiceDetails.InvoiceID = Invoices.InvoiceID WHERE (((Invoices.InvoiceDate) Between #8/1/2004# And #8/31/2004#) AND ((InvoiceDetails.DeliverBy)=0)) ORDER BY Invoices.InvoiceID;
Hi all, total newb here with a question i can't find answered anywhere. (you are my only hope) This database contains over 70k records and is a collection of user registrations over the years. Heres the issue.
After running the find duplicates query and get my list (over 8000 dupes) i get a sample like below. I cannot now run the append query as every other site or article says to. I can't set the primary key to surname because there are so many records that have the same last name but diff. first name. I need it to remove the dupes based on the EditDate, keeping the newest record.
I have the below code but I want to add a grouping to it so that if there is a duplicate building number it will not list it. Is there a way to add a grouping into the code to do this?
I am trying to combine two peculiar tables in Microsoft Access and have been unable to do so even after doing a lot of brainstorming and searching on the internet.
The two tables are spend and export Spend +-------------+--------+-------+-------+ | Country | Metal | Month | Spend | +-------------+--------+-------+-------+ | China | Iron | Jan | 100 | | China | Iron | Feb | 200 | | China | Iron | March | 300 |
I have just taken over some database which have a load of tables and queries that I suspect are no longer requirer. Is there anyway to see when a table or query was last USED in a database??
I have a table of 50,000 reccords. The table has 8 fields of theses eight fields I want to remove duplicates based on 4 of the fields in a query. Is there a way I can do this and keep the uniqe identifyer so that after the duplicates are removed from those 4 fields I can match them back up with the other four fields????
I have the following set up on a form to pull together a query (by form) and resulting report:
Publication Sector Product Region
Each publication can have multiple sectors/products/regions. The resulting query therefore duplicates the publication, for example:
Publication 1 Sector 1 Product 1 Region 1 Publication 1 sector 2 product 1 region 1 publication 1 sector 2 product 2 region 1
etc etc...
The report ONLY has publication on it, but as it is based upon the query utilising the 4 factors above, the resulting report is: Pub 1 Pub 1 Pub 1 Pub 2 etc
I want the report to only list the publications once - i have tried "hide duplicates" from the form field properties, however this hides the text but leaves a big gap on the resulting report when generated where the duplicate would be if it were not hidden.
There must be a simpler way to acheive this than getting another query to create a table based on the first query which (the table) only includes the publication name, and is filtered to remove duplicates through a primary key...
I am working on a database to manage newsletter subscriptions. Each subscriber record has the option of having up to four email addresses registered to his/her name.
Is there a way to check for duplicate email addresses in the entire database? It would have to compare all values in all four fields of all records.
Any ideas on how to implement such a thing? I'm clueless...
I am trying to design a delete query that has an additional criteria needed.
I want to delete identical IDs in one column only if there are identical values in an adjacent column.
So for example, in the table below I want to delete the last row where the duplicate ID is "2700023" because the Code field has identical values, "LRAC". I do not want to delete the second row because the Code field is different for the row.
I have two tables, one is of departments, and one is of people (with a FK denoting what department this person is in). Now consider the fact that there are duplicates in the departments table, and I would like to remove these duplicates. However, the duplicates have related records (in the people table). So, before removing the duplicates, I must update the FKs in the table of people (this is the step I'm having trouble with).
Here's an example:
As you can see, the "Sales" department is there twice. And both have a related record. What I want to do is: Update all DepartmentIDs (in tblPeople) to not point to duplicate records. In this example, that would be PersonID 2; Joe. His DepartmentID should update to "1" (as both "1" and "2" are "Sales").Delete the duplicates in tblDepartments (in this case, DepartmentID 2, "Sales").
The second step is no problem, it is only the first I am struggling with.
Also, the example posted here is just an example, the data I actually need to do this for is significantly more complex and there are many more records! In the attached database:
qry1: Simple query to find all duplicates (just used the query wizard) qry2: Just the first row of each duplicated departments (duplicates that shouldn't be deleted). In the example above, this would be the "2", "Sales" row in the tblDepartments table. qry3: Basically all qry1 rows that don't appear in qry2 qry4: All qry3 values, and their respective qry2 value.
This is what each of the (soon to be deleted) duplicate values' related records' DepartmentID should be updated to... There's no simpler way to phrase that, so using the example above, qry4 would return "2","1". This indicates that all people with a DepartmentID of "2" should be changed to "1" (so we can subsequently erase the department with the ID of 2.
This is as far as I have gotten. My next step is: Update all FKs in tblPeople based on qry4 (You can't set an update query's criteria to pull from another query, nor can you use the second query for the update value... or maybe you can, but I don't know about it).
Ref# Rev 97 b 98 c 99 c 99 e 100 c 100 b 101 a 102 b
I need to create a simple report but remove the duplicates (ex. Ref# 99,100). I need to delete the older Rev's (Ex Ref# 99 Rev C, Ref# 100 Rev B).Is this done throughRecordsets? will an SQL query do the trick?
We are a non-profit that does blind mailings for our membership drive. The company who we buy names and addresses from sends us a delimited file that has these fields as the headings
" ID, FULLNAME,COMPANY, ADR1, ADR2, CITY, STATE, ZIP, FIPS"
Once they send out the mailings, people then send in back a remit slip with a contribution that gets scanned through a program that creates a file that gives us these titles
"ALT ID, AMOUNT PAID, RUN DATE, TENDER, FUND, PURPOSE, SOLICITATION, MEMBERSHIP QUESTION, MEMBER TYPE, CONSTITUENT TYPE, SEGMENT"
The "ALT ID" and "ID" are the same in both tables.
I need to find a way to merge the tables and combine the fields that have the same ID # , and then have it create a csv file that reads like this (see below) for only the files of the people that responded so that I can import it into our membership software.
