``` 返回结果如下： ```shell +---------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ | VIEW | CREATE VIEW | CHARACTER_SET_CLIENT | COLLATION_CONNECTION | +---------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ | MV_TBL1 | CREATE MATERIALIZED VIEW "MV_TBL1" ("COL1", "COL2") COMPRESS FOR ARCHIVE REPLICA_NUM = 1 BLOCK_SIZE = 16384 USE_BLOOM_FILTER = FALSE TABLET_SIZE = 134217728 PCTFREE = 10 REFRESH FORCE ON DEMAND AS select "TEST_USER001"."TBL1"."COL1" AS "COL1","TEST_USER001"."TBL1"."COL2" AS "COL2" from "TEST_USER001"."TBL1" where ("TEST_USER001"."TBL1"."COL3" >= 20) | utf8mb4 | utf8mb4_bin | +---------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ 1 row in set ``` ## 使用视图查看物化视图信息 可以通过系统视图来查看物化视图的相关信息，可查看的视图有： | **视图名** | **功能描述** | | --- | --- | | [ALL_MVIEWS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477437) | 展示物化视图信息。 | | [DBA_MVREF_STATS_SYS_DEFAULTS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477299) | 物化视图刷新历史统计属性的系统范围默认值。 | | [DBA_MVREF_STATS_PARAMS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477376) | 展示与每个物化视图关联的刷新统计信息属性。 | | [DBA_MVREF_RUN_STATS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477190) | 展示物化视图的每次刷新运行的信息，每次运行均由 REFRESH_ID 标识。 | | [DBA_MVREF_STATS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477392) | 展示物化视图刷新的基本计时统计信息。 | | [DBA_MVREF_CHANGE_STATS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477302) | 展示物化视图刷新相关的统计信息。 | | [DBA_MVREF_STMT_STATS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477133) | 展示刷新语句关联的信息。 | | [DBA_SCHEDULER_JOBS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004477356) | 展示数据库中所有调度程序作业的信息。 | **示例如下：** 通过 `DBA_SCHEDULER_JOBS` 视图查看自动刷新物化视图 `mv_rc_swn_tbl1` 后台刷新的任务情况。 ```sql SELECT JOB_NAME,JOB_ACTION,START_DATE,REPEAT_INTERVAL,LAST_START_DATE,NEXT_RUN_DATE FROM sys.DBA_SCHEDULER_JOBS WHERE JOB_ACTION like '%MV_RC_SWN_TBL1%'; ``` #### 注意 Oracle 模式中视图 `sys.DBA_SCHEDULER_JOBS` 中字段 `JOB_ACTION` 匹配表名时，表名需使用大写字母。 返回结果如下： ```shell +----------------------------------+--------------------------------------------------------------------------+-------------------------------------+----------------------------------+-------------------------------------+-------------------------------------+ | JOB_NAME | JOB_ACTION | START_DATE | REPEAT_INTERVAL | LAST_START_DATE | NEXT_RUN_DATE | +----------------------------------+--------------------------------------------------------------------------+-------------------------------------+----------------------------------+-------------------------------------+-------------------------------------+ | MVIEW_REFRESH$J_1125899909162864 | DBMS_MVIEW.refresh('TEST_USER001.MV_RC_SWN_TBL1', refresh_parallel => 1) | 18-DEC-24 05.04.48.000000 PM +08:00 | current_date + INTERVAL '1' HOUR | 18-DEC-24 05.04.51.502947 PM +08:00 | 18-DEC-24 06.04.51.000000 PM +08:00 | +----------------------------------+--------------------------------------------------------------------------+-------------------------------------+----------------------------------+-------------------------------------+-------------------------------------+ 1 row in set ``` ## 相关文档 - [物化视图概述](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004479295) - [物化视图日志](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004479291) - [创建物化视图](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004479290) - [刷新物化视图](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004479296) - [物化视图查询改写](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004479298) - [删除物化视图](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004479294) 上一篇 下一篇 ![有帮助](https://gw.alipayobjects.com/mdn/ob_asset/afts/img/A*y6ocSqN8cqsAAAAAAAAAAAAAARQnAQ)![无帮助](https://gw.alipayobjects.com/mdn/ob_asset/afts/img/A*BG9IQJyLHF8AAAAAAAAAAAAAARQnAQ)![反馈](https://gw.alipayobjects.com/mdn/ob_asset/afts/img/A*eTWdQKCRKHwAAAAAAAAAAAAAARQnAQ)[AI](https://www.oceanbase.com/obi) 咨询热线
