如何在spark/scala中编写或调用-SQL游标？

是否可以在scala/spark中写入/调用游标？？我想从spark/scala代码中编写或调用SQL游标

declare
   cursor c1 is
       select DISTINCT earning_id from CN_TP_EARNINGS_ALL where rownum < 10;
   cursor c2(p_Assigned in number) is
       select SOURCE_EVENT_PERIOD_ID from  CN_TP_EARNINGS_ALL where 
       earning_id = p_Assigned;

begin
 for r1 in c1 loop
  dbms_output.put_line('------- start  --------');
  for r2 in c2(r1.earning_id) loop
     dbms_output.put_line(r2.SOURCE_EVENT_PERIOD_ID);
  end loop;
     dbms_output.put_line('------- end  -------');
 end loop;
end;

下面是用SQL编写的游标，我想从scala代码中调用它

declare
   cursor c1 is
       select DISTINCT earning_id from CN_TP_EARNINGS_ALL where rownum < 10;
   cursor c2(p_Assigned in number) is
       select SOURCE_EVENT_PERIOD_ID from  CN_TP_EARNINGS_ALL where 
       earning_id = p_Assigned;

begin
 for r1 in c1 loop
  dbms_output.put_line('------- start  --------');
  for r2 in c2(r1.earning_id) loop
     dbms_output.put_line(r2.SOURCE_EVENT_PERIOD_ID);
  end loop;
     dbms_output.put_line('------- end  -------');
 end loop;
end;

留在甲骨文公司。您可以使用迭代器，但似乎是错误的用例。
