Hello,
How can I import a large amount of new data in a pre-existing database. My table are already partially populated, I do not want duplicate. I try using the "Import" feature but it does not work with already 25.000 rows (yes my text file is well formated, the same data are successfully imported when the table is empty), I try using the "Find Duplicate" feature but it does not work either for the same reason. I cannot use Access to pre-clean my data because the table is too large. What is the solution to my problem?
