Re: system command in dblink?

["mike stanton" <mike.stanton@xxxxxxxxxxxxxxx>]

you could try creating a perl function

 

CREATE OR REPLACE FUNCTION "public"."system" (cmd varchar) RETURNS text AS
$body$
return `$_[0]`;
$body$
LANGUAGE 'plperlu' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;

 

then using it in this way

 

     sql = 'select system( '
        || ' ''/home/iv_fmaster/bin/main_wms 99 '
        || new.iddocsalida || ''' )';
                                                                
                 select dblink_exec('paso_lx',sql,TRUE)
                   into ifres;

Subject: system command in dblink?

Is it possible to execute system commands in dblink connections?

I need to execute \i /tmp/test.sh in a remote connection from my psql client prompt.
I connected with the remote db using dblink_connect.

select dblink_connect('conn_1', 'dbname=newdb');

Any help please.
