  • Maybe something like this?

    [dbadmin@vertica01 ~]$ vsql -Atc "select * from test;insert into test values ('Hi');commit;select * from test;"
    Hi


  • vsql -c runs all the SQL but only returns the results from the last query.
    $ vsql -Atc "select 1; select 2; select 3;"  3
    If you want all of the results, use pipes:
    $ echo "select 1; select 2; select 3;" | vsql -At  1  2  3    
    For vsql scripts that want to run lot of queries, I've had some good luck using \o:
    for x in system nodes schemata; do echo -e "\o /tmp/vsql-$x.out\nselect * from $x;\n\o\n"; done | vsql -At
  • Another option its redirection (almost same as example 1 of Ben Vandiver):
    daniel@synapse:~$ vsql << EOF
    > \pset format unaligned
    > \pset footer
    > select 1;
    > insert into table1 values (4, 'AA', '2015-01-01 12:00:00');
    > commit;
    > select * from table1 where id = 4;
    > \q
    > EOF
    Output format is unaligned.
    Default footer is off.
    ?column?
    1
    OUTPUT
    1
    COMMIT
    id|col1|date
    4|AA|2015-01-01 12:00:00

    Cheers ;)
