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.....

I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.

I am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. The copy and paste below from VS is a little messy. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens. All datatypes are string in VS and text in Access.
