I need help merging two databases. I have an access database that has address, city state zip, for my subscriber list. I recently had all the addresses updated and need to merge only the new addresses back to the original file (only 1000 have to be changed). The original file has a unique key and the appended file is in excel with the unique key as one of the columns. I want to keep the original unique key the same. Is there a way to do this without cutting and pasting all of the new data?
