*IT 存儲過程：足跡第七十八步：存儲過程裏的循環與定時

1.存儲過程

if(s<m) then

DECLARE

cursor mycursor is select * from VEHICLE_GPS_TRACK t where t.imei='12113298' and TIME > d and to_char(t.TIME,'yyyy-mm-dd')=to_char(sysdate,'yyyy-mm-dd') order by TIME;


BEGIN

end loop;

2.任務定時，實現定時增量同步

declare
job1 number; 
begin
 dbms_job.submit(job1,
     what => 'f_12113298;',
     next_date => sysdate,
     interval => 'sysdate+1/(24*60*60)'); -- 每隔1s處理一次用戶表
   commit;
end;
