Re: Help on function creating

Hello everyone, I'm using postgresql form an year and I have some
difficult to write a function to make an report. I'm running PostgreSQL
7.5.3 on i686-pc-linux-gnu (Mandriva 10.1). My table structure is:
Tabela " public.matricula"
         Column          |           Type           |    Modifiers

-------------------------+--------------------------+-------------------------------------------------
id                      | integer                  | not null default
nextval('seq_matricula'::text)
ref_contrato            | integer                  |
ref_pessoa              | integer                  |
ref_campus              | integer                  |
ref_curso               | integer                  |
ref_periodo             | character varying(10)    |
ref_disciplina          | integer                  |
ref_curso_subst         | integer                  |
ref_disciplina_subst    | integer                  |
ref_disciplina_ofer     | integer                  |
nota                    | double precision         | default 0
nota_exame              | double precision         | default 0
nota_final              | double precision         | default 0
conceito                | character varying(5)     | default
''::character varying
conceito_exame          | character varying(5)     | default
''::character varying
conceito_final          | character varying(5)     | default
''::character varying

I need to have an output like:
ref_pessoa | ref_disciplina1  | ref_disciplina2 | ... | ref_disciplina n
1          |  nota_final1     | nota_final2      | ... | nota_final n

How can I make this ? I know  that I need to declare an variable an than
make an for - loop, but I don't know how. Where can I get some examples
for this?
Thanks.
