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"
30356;"JOSE DE JESUS ";"977";"377";"2008-02-19";"FALSE";"2008-02-12";"2008-02-12 12:52:19.688381";"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

Flávio
