How do you call your function? You should call it like this:
SELECT * FROM seach_password('Flavio');
 
Replace Flavio with the login of someone in table_user.
Also watch out for the function name: if you copied my suggestion it = is seach_... and not search_...
 
I would also suggest you replace the
...t.cod_user IN (subselect)
by a join construction. I think it's more performant.

Thanks for your help

I think you have a quoting problem
You want something like
  WHERE login=3D 'Flavo'
But you're making something like
  WHERE login =3D Flavo
 
Something like this should work...
CREATE OR REPLACE FUNCTION seach_password(USER_FOO IN table_user.= login%TYPE)
RETURNS SETOF vw_change_password AS =
$BODY$
DECLARE
r vw_change_password%ROWTYPE;
USER_FOO alias = for $1;
BEGIN
  FOR r IN (
    SELECT = u.cod_user, u.user_name, u.openpsw, t.user_password, t.end, t.validate, = t.date_add, t.user_time, u.ok
    FROM usuario u, = change_user_password t
    WHERE u.cod_user =3D = t.cod_user  AND t.cod_user IN (SELECT cod_user FROM = table_user WHERE login=3D USER_FOO))
  LOOP
    RETURN NEXT r;
  END = LOOP;
  IF NOT FOUND THEN

Hi

Don't know = why I can't receive a return like my view fields (I'm newbie in plpgsql). = Postgresql returns me a erro . How can I received a answer like my view = structure?

When I Test my view I receive

SELECT  = seach_password('user_login_foo')

My view returns me

25746;"MARCELO ";"bio1";"bio1";"2008-02-19";"FALSE";"2008-02-12";"= 2008-02-12 12:51:40.229282";"TRUE"

It's OK

but when I use function it returns me

ERROR: = column "user_login_foo" does not exist
SQL state: 42703
Context: = PL/pgSQL function "search_password" line 14 at for over execute statement
Where is my fault?

Thanks
