So I want to return to the database way as the nearest to a spreadsheet. I tried importing my csv file using the copy command but nothing happens. I created a blank database and then issued the command: COPY databasename FROM '/filename.csv' | STDIN WITH DELIMITER ',' NULL '0.0E0' CSV Then I issue the command: \dl and there is nothing in the database just two empty columns appear, ID|Description. How to resolve please.
