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

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!
