Subject: Retrieve the column values of a record without knowing the names

Hello,

I've got the following function and I want to access the fields values of my
record by index. The problem is that my select is retrieving each record
line with all values and not each one of each row on my view... How can I
solve this problem? 

Thanks in advance.


CREATE FUNCTION fc_teste_tce(aluno integer) RETURNS character varying AS
$BODY$ 
DECLARE
  reg record;
BEGIN
  for reg in execute 'SELECT ARRAY (SELECT vw_teste_tce FROM
estagio.vw_teste_tce where aluno = ''3043'' LIMIT 20) AS campos' loop
    for j in 1..array_upper(reg.campos,1) loop
      raise notice 'Field Value: %',reg.campos[j];
    end loop;
  end loop;
  return 'ok';
END;  
$BODY$

LANGUAGE plpgsql VOLATILE;
