How to export vertica table data in sql file

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

COPY public.foo FROM STDIN DELIMITER '|';
