[SQL] Re: Retrieve the column values of a record without knowing the names

[arthur_info]

Wow, I don't know if I exposed the problem in the right way, but I'm not
achieving the solution with information_schema... Let me show the function:

CREATE OR REPLACE FUNCTION fc_teste_tce2(codigo_aluno integer)
  RETURNS character varying AS
$BODY$ 
DECLARE
  reg record;
  reg2 record;
  msg character varying;
  i integer;
BEGIN
  msg := '';
  i := 0;
  for reg in SELECT * FROM estagio.vw_aluno_tce where aluno::integer =
codigo_aluno loop
    for reg2 in select column_name
                from information_schema.columns 
                where table_catalog = 'seduc' and 
                      table_schema = 'estagio' and 
                      table_name = 'vw_aluno_tce' loop
          if reg.reg2.column_name = '' then --> how can I do this to check
if there's no value for the field?
            i := 1;
          end if; 
        end loop;             
  end loop;
  if (i = 1) then
    return 'Problems...';
  else
    return 'ok';
  end if;
END;  
$BODY$
  LANGUAGE plpgsql VOLATILE
  COST 100;


Thanks a lot!
