ORA-01652:unable to extend temp segment by num in tablespace name

今天在DataStage中出现这个错误：

F_APP_NB_L1,0: Oracle call failed; sqlcode = -1,652; message: ORA-01652: unable to extend temp segment by 128 in tablespace TEMP

出问题的SQL是这个:

select t.*
from F_APP_NB_L1 t
,(select a.appno ,a.classcode
,max(a.begtime) begtime
from F_APP_NB_L1 a
where a.endtime = '99991231999'
and exists (select *
from F_APP_NB_L1 b
where b.appno = a.appno
and b.classcode = a.classcode
and b.endtime < '99991231999')
group by a.appno,a.classcode) c
where c.appno = t.appno and c.classcode = t.classcode
and c.begtime = t.begtime ;

后改为：

with temp_nb as
(select a.appno ,a.classcode
,max(a.begtime) begtime
from F_APP_NB_L1 a
where a.endtime = '99991231999'
and exists (select *
from F_APP_NB_L1 b
where b.appno = a.appno
and b.classcode = a.classcode
and b.endtime < '99991231999')
group by a.appno,a.classcode)
select t.*
from F_APP_NB_L1 t
,temp_nb c
where c.appno = t.appno and c.classcode = t.classcode
and c.begtime = t.begtime

这样，etl就不报错了，同时速度快了很多。
