Postgres dblink_exec in trigger function

Question

I'm getting an error when a trigger is run and trying to run the following function

CREATE OR REPLACE FUNCTION insert_new_sessions()
    RETURNS trigger AS
$$
DECLARE
BEGIN
SELECT dblink_exec('dbname=billing  port=5432','INSERT INTO md.radacct_test(radacctid,acctsessionid,acctuniqueid,username) select New.radacctid,New.acctsessionid,New.acctuniqueid,New.username' );

    RETURN NULL;
    EXCEPTION    WHEN OTHERS THEN RAISE NOTICE 'insert_new_sessions SQL ERROR: %', SQLERRM;

    RETURN NULL;
END;
$$  LANGUAGE plpgsql;

The error:

ERROR insert_new_sessions SQL ERROR: missing FROM-clause entry for table "new"

Answer 1

Because you have NEW inside the string, thus interpreted as a string? Try concatenating the NEW.xxx values with the rest of the string. Eg. INSERT INTO md.radacct_test(...) SELECT ' || NEW.radacctid ||', ' || NEW.acctsessionid || ', ' || NEW.acctuniqueid || ', ' || quote_nullable(NEW.username));

Answer 2

I believe that the OLD and NEW keywords are case sensitive.
