Re: COPY TO order

Ahh, I see.

Like this from the command line :

psql --no-align --tuples-only --field-separator , -c "select
data,comment from test_table order by test_id ;" database >/tmp/file

From psql prompt :

\a\t\f,
select data,comment from test_table order by test_id \g /tmp/file
\a\t\f|

Either way you should get a file {/tmp/file} contaning :

27,some kind of entry
32,another kind of entry
16,yet another entry
...
