How to export vertica table data in sql file - vertica

Question

I wanted to export table data in vertica and generates a SQL INSERT script. I exported table schemas and generated a SQL script. Is there any way to export table data in vertica?
Thank you.

What you can do is to write a vsql script that puts its output to file.
Script exp.sql:
-- don't align
\a
-- tuples only
\t
\pset fieldsep '|'
-- write to workfile.sql
\o workfile.sql
-- get the create table statement into the workfile
SELECT EXPORT_OBJECTS('','public.foo',FALSE);
-- put the COPY command for in-line data into the workfile
SELECT 'COPY public.foo FROM STDIN DELIMITER ''|'';';
-- export the table's data
SELECT * FROM public.foo;
-- append a backslash-dot line to mark the end of the input of the copy command.
SELECT '\.';
Resulting workfile.sql:
CREATE TABLE public.foo
(
id numeric(37,15),
first_name varchar(256),
last_name varchar(256),
hire_dt timestamp
);
CREATE PROJECTION public.foo
(
id,
first_name,
last_name,
hire_dt
)
AS
SELECT foo.id,
foo.first_name,
foo.last_name,
foo.hire_dt
FROM public.foo
ORDER BY foo.id,
foo.first_name,
foo.last_name,
foo.hire_dt
UNSEGMENTED ALL NODES;
COPY public.foo FROM STDIN DELIMITER '|';
