Inserting A Duplicate Record In A (Access) Database?

Sep 24, 2009

For some reason my code is executing the INSERT query twice and putting duplicate records in my table. If I put a primary key on one of the fields I get a runtime error and it complains about the fact it can't add the record twice.The part of the code that INSERTs is near the bottom, bolded and italicized. I put the entire IF statement of code incase my logic is wrong.This is what's being executed when a user clicks a button

If listOfCompanies.Contains(cbx_Company.Text) Then
'If the list contains the company, UPDATE the record

DB/Reporting :: Delete Duplicate Record In Table Without Key?

Dec 12, 2010

I am working with some DBF database files and have an interesting dilemma. I need to search through a table, find duplicates and delete them. Problem... Table doesnt contain a key.

So Table looks like this:

Name, BadgeNum

I need to be able to find instances like this:

John, 10
John, 10

and then delete just one iteration of John, 10.

Is this even possible? A "DELETE FROM TABLE WHERE BadgeNum=10" will delete both.....

May 25, 2009

i've added new item called service- based database. after that, i've created doctor table, course table, exam table, and an empty table called exam_report to allow program selects randomly from the other tables.

Asp.net - Inserting Data But Getting "duplicate Values" Error

Jan 15, 2011

I am attempting inserting into an Access database, and the insert is successful (when I open the database the data is there), but I'm getting an error: "The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."

This is really confusing me. No matter what I insert, it still gives me the same error. And I don't understand why it's giving me an error even though it's working. Here's my codebehind:

Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick
