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!
