I have the following function.  I want to call it with a username and then it return a user_id for that user.
CREATE OR REPLACE FUNCTION public.get_user_id (username char) RETURNS int4 AS
$$ SELECT user_id from users where username = '$1' $$
LANGUAGE 'sql'
GO

That doesn't work.  when I execute the function.
select public.get_user_id('cmuench') as user_id   I get NULL back.  However when I just do a straight select with the username in the where clause it reuturns a 1 like its supposed to.
