物化视图

物化视图基本操作

创建物化视图日志
create materialized view log on cps_identity_account  including new values;

删除物化视图日志
drop materialized view log on cpsmgt.cps_identity_account;

创建视图
----(1)-----有主键
create materialized view mv_cps_identity_account
refresh fast on demand
as
select * from
from cpsmgt.cps_identity_account@ic;

----(2)-----没有主键和索引
create materialized view lbi_ods.mv_cps_trans_record
refresh fast on demand with rowid
as
select * from cps_trans_record@tc;

------------删除视图
drop materialized view  mv_cps_identity_account;

------------刷新视图(原表不含分区)
create or replace procedure prc_o_mv_cps_identity_account(         iv_min     in varchar2/*,
                                                  oi_return out integer*/)
     authid current_user
/** head
