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 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 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?
I have imported a table from Excel. The table contains a long list of names and there are quite a lot of duplicates. How do I remove the duplicates so I can import the clean list into a value list in Access ?
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 using information pulled from a separate database to create a new database for mail merger purposes. I have created delete queries that go out and delete specific records from the new database to help us get the proper list before setting up the mail merge. However, now I am stuck. We have customers that have multiple accounts with us that are qualified for this mailing, yet each customer needs to receive only one mailing. The table looks like this essentially. Table 1id statCode acct custNumber* addy-etc. *This is the field in which we can find exact duplicates. What I need to do is remove the duplicate entries and leave at least one of the entries within the table. It does in fact need to remove the whole record, but as I said leave at least one of the records behind. Can someone please help me to find a solution to this. I guess I should add that I am not very good with Access and I use it very sparingly. I assume that the above can be accomplished using a SQL statement. Any help will be greatly appreciated. LR**EDIT** I also needed to add that I do need to exclude 000 00 0000 from being removed because of duplication.
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 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 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).
I am attempting to filter the data in query design such that it will not return anyone in the database has there name present more than one time.
For example, in the image below under the Owner_Name field there is "Abbot, Mark C Etux Wanda C". This name appears twice in the database. My criteria is the name can only appear once, therefore this record would not be returned after the query. In query design I would like it to return only name records that appear once in the entire database if there is a way to structure that.
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?
I've been working on a procedure to step through the recordset and add the data one record at a time so I can get rid of the duplicates.
I've tried a few approaches, but this is where I'm at now.
Code:
Dim rs As DAO.Recordset Dim rsHH As DAO.Recordset Dim rsPhone As DAO.Recordset Dim rsEmail As DAO.Recordset Dim rsAddress As DAO.Recordset Dim rsPerson As DAO.Recordset Dim db As DAO.Database Set db = CurrentDb
I have two tables in my Access database. Table 1 has three columns, First Name, Last Name and Phone Number. Table 2 has just 2 columns, First Name and Last Name. What I would like to do is write a VBA macro to consolidate Table 2 into Table 1 and insure any duplicate First Name-Last Name combination is removed.
Table1
Code: F.Name L.Name Tel.N. John Smith 12345 Larry Miller 12344 Tony Woods 12333
Table2
Code: F.Name L.Name Albert Black Larry Miller John Bush
Table1 Post-Macro
Code: F.Name L.Name Tel.N. John Smith 12345 Larry Miller 12344 Tony Woods 12333 Albert Black John Bush
As you can see a table can be linked to any number of tables.
Now for my actual question. I don't want to have to type in all the queries and tables. I would like to choose any query and table from a drop down of all possible queries and tables that are currently in the database - like a list, where the list contains all the possible values.
im in the middle of developing a database to log DOWNTIME of various machines in the factory. Basically myself and others will use it to log breakdown details and the amount of time (in HH:MM) the machine was off.
I have a form which will list details of a certain machine in a list box which i can populate using a query.
The list box will display 3 columns: Date of Breakdown, Machine Name and Downtime
I then have a text box below this that i would like to display the TOTAL amount of downtime for that machine (The listbox may have different information in it depending on the query criteria, e.g. It might display a certain month for a certain machine).
THE ISSUE i am having is its proving to be difficult to get the correct sum of the accumulative time to display correctly in the text box.
Is there a way i can use a query to calculate the total time of a column and return a value which is formatted as time (like this hhhh:mm or dd:hh:mm) or preferably use some VBA code on the form itself to total up the DOWNTIME column of the list box and display it with the correct format in the text
I have gotten close, but as the total amount of time exceeded 24 hours, it went past 00:00. I'm assuming it treated it as a clock and went into the next day? This is NOT what i am after, i need the total amount of days, hours spent on the machine and not a time of the day.
tblEmployees - Stores employee data tblProcess - Stores process data tblTraining - Stores data on which employees have trained on which process
tblEmployees has a 1 to many relationship to tblTraining through empID tblProcess has a 1 to many relationship to tblTraining through pcsID
When a new Process is added, a query auto populates tblTraining with 1 record for each employee in tblEmployees. Equally when a new Employee is added, a query auto populates tblTraining with 1 record for each Process in tblProcess.
In theory this should ensure that every employee has a training record for every process (and vice versa). However, as many of us know, never assume the user wont find a way to mess things up!
So i want to have a query that can show me Employee and Process without a training record. I have been manipulating a SELECT (SELECT) query to pull this together, but i just keep coming up blank.
I have attached a copy of the relevant tables and query. I have deliberately deleted a training record for empID 6 on pcsID 1 AND empID102 on pcsID 2 (qryCheckTrainingRecordsBalance will show the processes these 2 DO have a training record for).
