Export Query Results To A CSV
Digging through the results of queries in Postgres's psql is great if you
are a programmer, but eventually someone without the skills or access may
need to check out that data. Exporting the results of a query to CSV is a
friendly way to share said results because most people will have a program
on their computer that can read a CSV file.
For example, exporting all your pokemon to /tmp/pokemon_dump.csv can be
accomplished with:
copy (select * from pokemons) to '/tmp/pokemon_dump.csv' csv;
Because we are grabbing the entire table, we can just specify the table name instead of using a subquery:
copy pokemons to '/tmp/pokemon_dump.csv' csv;
Include the column names as headers to the CSV file with the header
keyword:
copy (select * from pokemons) to '/tmp/pokemon_dump.csv' csv header;
