I have a large, growing database. Will hold 100 Million + entries. Each week I will import 1 CSV file to the database, containing millions of rows. The database has 3 columns and should only import the row if the data in column 1 does not already exist in the databse. Small example: 1 2 3 (column number) a b c (accepted) d e f (accepted) a g h (rejected as "a" already exists in the database) After importing the new data, I would like to export just the entries that were added to the database (not the whole database).
