Hi, 

I`m using Before Delete..


CREATE TRIGGER nfentrada_item_tr1
  BEFORE DELETE 
  ON public.nfentrada_item FOR EACH ROW 
  EXECUTE PROCEDURE public.nfentrada_item_ad0();

here is my nfentrada_item_ad0();

    delete
      from MOVIMENTO
      where (IDEMPRESA = OLD.idempresa) and
            (upper(TABELA) = 'NFENTRADA_ITEM') and
            (CODIGO = OLD.idnfentrada_item);
      return old; 

I just want to delete all row in my MOVIMENTO table with these conditionals..

Thanks,

Hi,

You're using a trigger AFTER, in your case could be BEFORE?
Cause when you use AFTER the var OLD not exists...
I don't know if I understand exactly what you'll do to ativate this trigger..
but I think maybe is it..

try..
