Question

每当我的游标循环中的任何select语句无法获取数据时，我都需要继续循环。我想处理相同的异常。此过程只要在连续性中找到数据就会插入数据，但只要游标选择的o.id不保存相关数据，它就会存在循环，并且只插入先前获取的记录的数据，并且不会继续循环。

CREATE OR REPLACE procedure order_violation1(
   p_type          number,
   p_code          varchar2,
   p_submit_from   date,
   p_submit_to     date,
   p_approved_from date,
   p_approved_to   date,
   p_flag          number,
   p_status        varchar2
) is 
  pp_type varchar2(100);
  pp_company varchar2(50);
  pp_code varchar2(20);
  pp_ord_num varchar2(50);
  pp_status varchar2(50);
  SUBMIT_DATE date;
  APPROVAL_DATE date;
  ORDERING_RATIO_FLAG number;
  pp_submit_date date;
  pp_app_date date;
  pp_package varchar2(3000);
  pp_flag NUMBER;

  cursor pp_id is
     select distinct o.id 
       from orders o,
            partnerprofile pp
      where type_id=p_type 
        and o.ordering_ratio_flag=p_flag 
        and pp.id=o.to_partner_id 
        and decode(P_CODE,null,'1',pp.code) = decode(P_CODE,null,'1',p_code)
        and decode(p_submit_from,null, to_date('01/01/01','dd/mm/yy'),
                   to_date(submit_date,'dd/mm/yy')) between 
            decode(p_submit_from ,null,
                   to_date('01/01/01','dd/mm/yy'),p_submit_from)  and 
            decode(p_submit_to,null,to_date('01/01/01','dd/mm/yy'),'05-JUL-14')

  FOR r_partner IN pp_id
  loop

  END;

正如尼古拉斯所指出的，以前的方法在这里不起作用。你必须在下面的循环中使用异常处理来处理这个问题。

 LOOP
     BEGIN
    -- select code
    exception
        when no_data_found then
          continue; 
     END;
     -- insert code
    END LOOP;

还继续;是11gr1及以上的功能，对于较旧的功能，你将不得不使用goto。

   LOOP
    BEGIN
    -- select code
    exception
        when no_data_found then
          goto label1;
     END;
    -- insert code 
    <<label1>>  
    null;
    END LOOP;

运行游标循环时出现no_data_found错误
