What tool are you using for the upload?
I can't find an account for you in our system to see what extensions you may have purchased, can you provide an email address so I can see what you have purchased?
for DW 8, we used to offer a Tool called Digital File pro for file uploads and Data Assist for managing information in the database.
With Digital File Pro, you would use the Data Assist insert record behavior to save the data to the database, for the file column, you would use the Uploaded Files (File Field Name) -> Server File Name binding to save the uploaded file name to the database. you need to use the Data Assist insert behavior because the native DW insert behavior does not allow access to bindings hat do not come from the form.
