oracle物化视图快速更新

建立测试表

create table T_table nologging as select * from dba_objects;create table t_table_1 nologging as select * from dba_tables;

--建立日志记录

create materialized view log on T_table with rowid ,sequence(object_name,object_type,owner) including new values;create materialized view log on t_table_1 with rowid,sequence(table_name)  including new values;

--建立物化视图

create materialized view mv_t_table nologging refresh fast on demand with rowid START WITH TO_DATE('21-08-2017 10:09:08', 'DD-MM-YYYY HH24:MI:SS') NEXT SYSDATE + 1/(24*60) as select count(*),a.object_type,a.owner from T_table a,t_table_1 b  where a.object_name=b.table_name group by a.object_type,a.owner

--测试

select * from mv_t_table where owner='SYSTEM';delete from t_table where owner='SYSTEM';insert into t_table select * from dba_objects where  owner='SYSTEM';

--查看日志生成量

select a.name, b.value from v$statname a, v$mystat b where a.statistic# = b.statistic# and a.name = 'redo size';

--查看刷新日志

SELECT owner,mview_name,last_refresh_scn,last_refresh_date,query,REVISION FROM dba_mview_analysis WHERE owner='UTF32';

--查看日志记录表,MLOG$为日志记录表，一旦更新完成，此表的内容会被清掉；

select * from MLOG$_T_TABLEselect * from MLOG$_T_TABLE_1;
