SELECT statement in stored procedure

Hi,

I have the following stored procedure :

CREATE OR REPLACE FUNCTION immense_sp001(IN username VARCHAR, IN
strhash VARCHAR)
RETURNS SETOF accounts LANGUAGE plpgsql
AS '
    DECLARE

      Profile_Detected INTEGER :=0;
      act accounts%ROWTYPE;
      rec RECORD;

    BEGIN

        /* detect if the user logged in exists in database*/
        SELECT count(*) INTO Profile_Detected FROM accounts
          WHERE login=username AND pwd=strhash;

        if (Profile_Detected = 1) then
            SELECT INTO act * FROM accounts;
            FOR rec IN select login,status from accounts LOOP
              RETURN NEXT rec;
          END LOOP;
        end if;
        return;
    END;
';


so it should return only 2 fields from my account table (login and status).
however it does not work.

if i replace the line "FOR rec IN select login,status from accounts LOOP" by
FOR rec IN select * from accounts LOOP

it works but i get all fields from my accounts table.

So how can i get only login and status ?

thanks a lot,
Alain
