Oracle游标的简易用法

 create or replace procedure NW_DelYW(iOPERATION_ID number,
                                  sUserID      varchar2) is
   sCurDJBH yw_operation_link.djbh%type;
   cursor table_yw(ywid yw_operation.id%type) is
     select * from yw_operation_link t1 where t1.operation_id = ywid;
 begin
   for dr in table_yw(iOPERATION_ID) loop
     sCurDJBH := dr.djbh;
     --取得opercationid
     /*   select t1.operation_id
      into sOperationID
      from yw_operation_link t1
     where t1.djbh = sCurDJBH;*/

     --写日志
     insert into log_zfywinfo
       (DJBH,
        DJDL,
        DJXL,
        DLMC,

       select distinct sCurDJBH,
              t4.id,
              t3.id,

              t1.zl,
              sysdate,
              sUserID,
              (select tt.name from pw_user tt where tt.id=sUserID)

         join BUSINESS_CLASS t4
           on t4.id = t3.parent_id
        where t1.ID = dr.operation_id;
 exception

     rollback;
     dbms_output.put_line(sqlerrm);
 end NW_DelYW;

Oracle使用cursor 游标循环添加删除更新。
