Oracle rownum 分页注意事项

select *
from (select temp.*, rownum r
from (select distinct r.resource_id,
r.RESOURCE_OFFICIALNAME,
r.RESOURCE_ISRELEASE,
r.corp_copyright,
p.Pix,
e.editcommend_id
from tb_resource_info r
left join (select NVL(count(primarvideo_id), 0) as Pix,
resource_id
from tb_resource_primarvideo
group by resource_id) p on r.resource_id =
p.resource_id
left join tb_editorcommend e on r.resource_id =
e.resource_id order by r.resource_id desc) temp
where rownum <= 10
order by temp.resource_id desc)
where r > 0
order by resource_id desc

与

select temp.*
from (select distinct r.resource_id,
rownum r,
r.RESOURCE_OFFICIALNAME,
r.RESOURCE_ISRELEASE,
r.corp_copyright,
p.Pix,
e.editcommend_id
from tb_resource_info r
left join (select NVL(count(primarvideo_id), 0) as Pix, resource_id
from tb_resource_primarvideo
group by resource_id) p on r.resource_id =
p.resource_id
left join tb_editorcommend e on r.resource_id = e.resource_id
order by r.resource_id desc) temp
where r > 0
and r <= 10
order by temp.resource_id desc

两种分页有区别 第一种好。试过以后就知道原因了。
