解决方案：
create materialized view MV_TMP_16

refresh fast on demand

start with to_date('14-02-2014 17:03:16', 'dd-mm-yyyy hh24:mi:ss') next SYSDATE+ 3/1440

enable query rewrite

as

select SO.rowid arowid, CO.rowid browid, SO.ID,so.name, CO.Pid,co.id as co_id

from tmp_mv1 SO, tmp_mv2 CO

where SO.ID= CO.pid;

注：这里必须要加上rowid，否则就会报错
