haitao:
3个select是没错,错(当然是我认为错)在 where rownum<=3000出现的层次,我认为它应该在再外一层,才符合昨天说的通用模式

select * from( select rownum rn ,c.* from (select
T3.rowid T3_id,
T3.recno, T3.pdate
from T3
JOIN T2 on T2.idnum=T3.idnum and T2.recno=T3.recno
JOIN T1 on T3.idnum=T1.idnum
where T3.dumpstatus<>'-'
and (T1.OSTATUS not in ('C','P'))
and T2.PCODE = 'IC'
and T1.confirm = 'Y'
and (T3.pdate>=to_date('20100401','yyyymmdd'))
and (T3.pdate<=to_date('20100531','yyyymmdd'))
and (T3.dumpstatus <> 'C')
Order By T3.idnum desc,T3.recno asc, T3.pdate asc
)c where rownum<=3000
) where rn >1500
我认为就是最后2行应该改为
)c
) where rn >1500 and rn<=3000
