三種分頁的寫法:
1.使用minus,原理就是查詢出前100行的資料 減去 查詢出前50行的資料12
3select
*
from
data_table_sql
where
rownum<=100
minus
select
*
from
datat_able_sql
where
rownum<=50
2.查詢出所有資料的rownum,然後再選擇50到100的資料(不推薦)12
select
*
from
(
select
t.*,rownum num
from
data_table_sql t)
where
num<=100
and
num>50
3.限定範圍100條資料,並查詢出這100條的rownum,然後再選擇50到100的資料12
3select
*
from
(
select
t.*,rownum num
from
data_table_sql t
where
rownum<=100 )
where
num>50
