定义游标：

    cursor calenderStatus_cur     is    select * from ut_calenderStatus ;    vr_calenderStatus      ut_calenderStatus % rowtype;

打开游标，提取游标中的数据到游标行中：

    open calenderStatus_cur;        loop          fetch calenderStatus_cur into vr_calenderStatus;          exit when calenderStatus_cur % notfound;          up_日历_产品开放期设置(pi_serviceid,pi_opid,vr_calenderStatus.Calenderstatus,vr_calenderStatus.Fundcode,'0',pi_rq,pi_begin,pi_end,                                       vr_calenderStatus.m,vr_calenderStatus.n,vr_calenderStatus.Prolong,po_returnmsg ,po_returncode);           if po_returncode <> '0000' then           rollback;           return;          end if;                  end loop;    close calenderStatus_cur;
