Thread: creating a dumpfile from a view

creating a dumpfile from a view

Hi, I'm trying to create a dumpfile for a client.  The data is gathered
from about 7 tables, and I need to output all the columns as the client
wishes.

I figure the best way to this is to collect data from multiple tables
and putting them into a view, and using the client's desired names to
be the column headings of this view.  Then, I'd dump the data from a
view, and it'll all be ready for delivery.

The problem I run into is that when I dump from a view, I just get the
query that defined it in the first place.

pg_dump --table=demtest dbname

Output:
--
-- PostgreSQL database dump
--

SET client_encoding = 'SQL_ASCII';
SET check_function_bodies = false;
SET client_min_messages = warning;

SET search_path = amt, pg_catalog;

--
-- Name: demtest; Type: VIEW; Schema: amt; Owner: postgres
--

CREATE VIEW demtest AS
    SELECT foo.serial_no, foo.course_id, foo.writer_id,
foo.assignment_type, bar.critique_serial_no, ...;


ALTER TABLE amt.demtest OWNER TO postgres;

--
-- PostgreSQL database dump complete
--



Would anyone know how to dump the data from the view?  I tried the
following, but it doesn't work:

Thanks!

With 8.2, you can COPY a VIEW.

At the moment, you can create a new table as select * from the view and
take a dump from this table.
