    Compare table data with data in csv file


      Hi, I have a database table with ~32 milj rows. I want to compare the data from a csv file(~ 1500000 rows) with the data in a specific database column. And as a result I want to see what rows exists in both the csv file and db and what records in csv file are unique. The text I'm searching for is VARCHAR2. I am not allowed to export the database table so that's not an alternative. This is also a production environment so one need to be careful not disturbing the production.
