Append table with duplicate entries

Append table with duplicate entries
Views: 3
I have this table that I have appended records to. it has about 13000 records. When I first started appending records to this table from the original table I had the AddressID set to auto number.

Now it is set to long integer. But, I don't know how I can delete all of the duplicate entries. There is a time stamp, but sometimes it has just the date and sometimes it has time and date.

I tried to run a Find duplicate query, but it wouldn't let me choose the Problem column, which would be the field that would show if it were a duplicate entry. What can I do todelete the duplicates? This table should only have about 5000 records.

How do I stop duplicate entries in a table from an append query?

How do I get my append query working so it doesn't append duplicates onto an existing table? Currently if I run the append query I get multiples of the same data?

Append Query

I am trying to append to my Ledger credits showing in my downloaded Bank Statements. In my Ledger Table I have set 3 fields as Primary Keys (Donor Number, Amount and Date) as there should never be duplicate entries for all 3 fields.

My append query selects the credits from my Bank Statement and inserts them into the Ledger. But I would expect the use of the 3 Primary Keys to ensure that only new credits are added to the Ledger.

But I am finding that all credits (including entries already in the Ledger)

Duplicate Values

I have a handheld barcode scanner which sends data to a CSV file that is then imported to an Access 2003 database. From the import table, the data is appended to a user table with primary keys set to prevent duplicate data. I use 5 fields to make a primary key. The problem is that we update one field of the five to indicate a process. This changes the data in the user database and allows the original record to be re-imported as a duplicate because that particular field does not match anymore.

I am looking at how best to address this. I do have an autonumber field that I could use to prevent duplicate entries from being imported, but I am not aware of the ability to do 2 successive key check operations on an append query.

My next thought was to append with the duplicates and then do a delete query. I need to keep the record with added data, not the one that will be reimported. Not sure how I could do that query

Create a Query in Microsoft Access to Find Duplicate Entries in a Table

There are many causes for duplicate data: for instance if you have multiple users entering data simultaneously via linked tables, or you might inherit a table with duplicate data already entered.
Running into duplicate data in an Access Database can be quite annoying during the hectic workday, so I decided to write up a technique to help identify the duplicate records so you can manually handle them.

Append Query position

I am quite new to using access and I have a database set up with date, title and event. I have a table with 2000 entries and have created a form to add new entries to the table -- where lies my problem. I have created an append query with each column of the table that references the table and each references the correct combobox/textfield on the form. I have a "submit" button on the form that runs the query with the data entered on the form. After I click submit, a confirmation message comes up and I click yes to run the query. Then a second window comes up that says "You are about to append 0 row(s)" -- which is not my intention.

It's probably a small thing, but I have never used this append function before and am not totally sure how it runs. What do I need to do to make it append the data that it is passed?

How to prevent duplicate entries????

I'm trying to prevent duplicate entries into a movie database. I'm trying to submit actors names on a form, but if their name already exists in my actor table, then how do I have the form tell me they already exist and lets me select that entry that's already in the table? I would like to know how to do this in the Macro builder not SQL

Show and list duplicate entries in table

Hope somebody can help. I want to have the ability to check for duplicate entries - if duplicate, I want all the duplicates to display(list) in a new field.
This is a warranty database and I'd like to see all the previous issues (claim ID's) relating to certain serial number.
I'm very new to Access but I know there's a way of doing it but I just don't know how. I've tried searching for the solution everywhere but I've only come accross articles about removing duplicates which I don't want

append query

I'm trying to make a query that will append data from one table into another table. I've done this successfully, however I only want to append entries that have a new update. If a row is the same as it was before, I don't want it to be appended to the new table.

For example: My first table is a list of ongoing projects. One project may have an update added to a field, but another project may not. Right now my query is appending every row to the new table whether or not it is the exact same as it was previously (aka no updates, nothing new).
