1.根據ROWID來分 select * from t_xiaoxi where rowid in(select rid from (select rownum rn,rid from(select rowid rid,cid from
t_xiaoxi order by cid desc) where rownum<10000) where rn>9980) order by cid desc; 執行時間0.03秒 2.按分析函數來分 select * from (select t.*,row_number() over(order by cid desc) rk from t_xiaoxi t) where rk<10000 and rk>9980; 執行時間1.01秒 3.按ROWNUM來分 select * from(select t.*,rownum rn from(select * from t_xiaoxi order by cid desc) t where rownum<10000) where
