游标循环和continue语句：意外的行为

Question

我可能是俯瞰由于最后期限紧张的东西。但是，这种行为让我感到吃惊。 这看起来好像光标缓存100行和continue语句刷新缓存 并开始一个新的高速缓存取回的第一个记录。

我范围缩小到下面的脚本：

drop table test1;

create table test1 (test1_id NUMBER);

begin
  for i in 1..300
  loop
    insert into test1 values (i);
  end loop;
end;
/

declare
  cursor c_test1 is
  select *
  from test1;
begin
  for c in c_test1
  loop
     if mod(c.test1_id,10) = 0
     then
      dbms_output.put_line(c_test1%ROWCOUNT||' '||c.test1_id||' Continue');
      continue;
     end if;
     dbms_output.put_line(c_test1%ROWCOUNT||' '||c.test1_id||' Process');
  end loop;
end;
/
