function no return

Question posted by: autogoor@yahoo.com (Guest) on November 23rd, 2005 02:04 AM

I define a function


CREATE OR REPLACE FUNCTION my_function(n varchar) RETURNS void AS $$
DECLARE
...
BEGIN
...
END;
$$ LANGUAGE plpgsql;

It has no return. How can I invoke it? SHould I still use

select my_function('aaa')

Thanks,

autogoor
