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
If LaborChecked Then

There is a form in which the choose the worker name, the item they were making, how many were made, damaged, or received damaged from the supplierHowever when they click on the "Update" button to insert the record..i get my custom message that it failed and the record is not inserted. I put a TRY...Catch... around the insert query and it didn't generate an error message.I have been following the code in the OLEDB BASICS tutorial so I am not sure what the problem is at this time.

Inserting Data From One Access Database Into Another?

Jun 6, 2012

I have a deployed desktop application which uses an Access Database. I have a need to update the databases which are in the field by adding a few extra fields to some tables to support new functionality. Thedatabases is password protected.

The process I am following is to ship a new empty database which contains the new fields (these fields are set to not require entry, accept nulls and they are not indexed) and then add functionality to the application which selects the data from each table in the current deployed DB and inserts it into the same table new template database. Then I kill the original db, rename the new template to be the file used by the application.

I am using OLEDB to communicate with the database and have tried using an 'INSERT INTO' but cannot get the syntax right - I used this example[URL]..but it throws and invalid argument when I try to supply a database password
