How to handle error within a FOR loop

Question

Hi all,
For the code:
begin
    for vc1 in (select *
                  from xx_primavera_invoices_detail
                 where transfered_to_ar = 0
                   and cust_trx_type_id not in (1000, 1003, 1016, 1023, 1040)
                   and act_end_date is not null) loop
      insert_into_ar_interface(vc1.amount, vc1.uom_code, vc1.quantity, vc1.unit_standard_price, vc1.cust_trx_type_id
                              ,vc1.description, vc1.interface_line_attribute1, vc1.interface_line_attribute2, vc1.interface_line_attribute3, vc1.service_code
                              ,vc1.gl_date, vc1.orig_system_bill_address_id, vc1.orig_system_bill_customer_id, vc1.segment2, vc1.segment3,vc1.customer_name,vc1.payment_type,vc1.currency_code)
    end loop;
    update xx_primavera_invoices_detail
       set transfered_to_ar = 1
     where transfered_to_ar = 0
       and cust_trx_type_id not in (1000, 1003, 1016, 1023, 1040)
    end;I want to add an exception statement if there is no value returned in VC1. I guess i'll never go into the loop statement because no data found in VC1 but the UPDATE will be executed...
Any ideas?

Hi,
declare
  v_i_was_in_loop  boolean;
begin
  v_i_was_in_loop ;= false;
  for cur in (select ..)
  loop
    null;
    v_i_was_in_loop := true;
  end loop; 
if v_i_was_in_loop = true
then
   update...
end if;    
end;
