I have somes files in xls that are refreshed every month (Same columns every files) and i need to import only new rows in a accessdata base
Why have you added Counter Generation to your table? Error you are seeing is probably because you don’t have Counter column (created with above mentioned node) in your database and DB nodes require exact column match. Maybe you need to rename it or use some other column in WHERE clause?
You are free to ask questions here (even stupid ones although I would call this one stupid) and answer them as well
