Thread: RAISE function misuse ?

Hi,
I obtain the following output:

idns_target=# select test();
INFO:  hello !
CONTEXT:  SQL statement "SELECT  hello()"
PL/pgSQL function "test" line 2 at perform

Using the two following functions:

CREATE OR REPLACE FUNCTION hello() RETURNS void AS $$
BEGIN
    RAISE INFO 'hello !';
RETURN;
END;
$$ LANGUAGE plpgsql;

CREATE OR REPLACE FUNCTION test() RETURNS void AS $$
BEGIN
    PERFORM hello();
RETURN;
END;
$$ LANGUAGE plpgsql;

I would like to know:
1. Is there anything wrong using RAISE this way.
2. Is there a way to get rid of the output:
CONTEXT:  SQL statement "SELECT  hello()"
PL/pgSQL function "test" line 2 at perform

I use PostgreSQL/psql 8.1.0

Thanks,

Patrick

Not in the sense of the code doing something it shouldn't.

test=> \set VERBOSITY terse
test=> select test();
INFO:  hello !
 test
------

(1 row)

Is there a better way to output text from within a function ?
