Hi All,
I understand that copy and \copy commands in PostgreSQL work only for tables. I want it to export the data from varies tables. Instead, I can create a view for the list of tables. Can the copy or \copy commands be utilized to operate on views directly? Please let me know on this.
Thanks and Regards,
Siva.

Hi Andreas,
I tried the command as below. It failed. Please correct me.
\copy (select * from view1) to '/sample.csv' delimiters ',' csv header;
ERROR: \copy: parse error at "select"

Hi,
COPY (SELECT ...) appeared in 8.2.x so you need to upgrade.

Hi,
I have installed Windows version of Postgres 9.0.4 in my windows machine to test the new copy command as detailed in the below e-mails. When I run the command in SQL Editor, I got permission error. But I am running as an administrator.
COMMAND: copy (select * from employee) to 'C:/emp.csv'
ERROR: could not open file "C:/emp.csv" for writing: Permission denied
********** Error **********
ERROR: could not open file "C:/emp.csv" for writing: Permission denied
SQL state: 42501
COMMAND: \copy (select * from employee) to 'C:/emp.csv'
ERROR: syntax error at or near "\"
LINE 1: \copy (select * from employee) to 'C:/emp.csv'
^
********** Error **********
ERROR: syntax error at or near "\"
SQL state: 42601
Please correct me where I am going wrong. FYI, I am running under the administrator accounts of both Windows Login and PostgreSQL.
Thanks and Regards,
Siva.

1. you need to have a proper permissions where the .csv file creating.
2. In windows you need to use as below
postgres=#\copy (select * from employee) to 'C:\\emp.sql'

That version is *totally* unsupported on Windows. Not only that, but
you're running an ancient point-release - you are missing *19* patch
releases worth of bug fixes. The latest point-release is 8.1.23 !
Here is a list of all the fixes you are missing out on:

has the permissions of the "postgres" user. You must save the file
somewhere the "postgres" user as write access. Either create a folder
and give "full control" to the user "postgres", or write the export
within the existing postgresql data directory.COMMAND: \copy (select * from employee) to 'C:/emp.csv'You are not using psql. "\copy" is a psql command. I don't think it's
