``` 返回结果如下： ```shell +---------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ | View | Create View | character_set_client | collation_connection | +---------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ | mv_tbl1 | CREATE MATERIALIZED VIEW `mv_tbl1` DEFAULT CHARSET = utf8mb4 ROW_FORMAT = DYNAMIC COMPRESSION = 'zstd_1.3.8' REPLICA_NUM = 1 BLOCK_SIZE = 16384 USE_BLOOM_FILTER = FALSE TABLET_SIZE = 134217728 PCTFREE = 10 REFRESH FORCE ON DEMAND AS select `db_test`.`tbl1`.`col1` AS `col1`,`db_test`.`tbl1`.`col2` AS `col2` from `db_test`.`tbl1` where (`db_test`.`tbl1`.`col3` >= 20) | utf8mb4 | utf8mb4_general_ci | +---------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ 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** | | --- | --- | | [DBA_MVIEWS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004478218) | 展示物化视图信息。 | | [DBA_MVREF_STATS_SYS_DEFAULTS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004478326) | 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-1000000004478330) | 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-1000000004478285) | 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-1000000004478154) | 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-1000000004478309) | 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-1000000004478143) | 展示刷新语句关联的信息。 | | [DBA_SCHEDULER_JOBS](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000004478255) | 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_swn1_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 oceanbase.DBA_SCHEDULER_JOBS WHERE JOB_ACTION like "%mv_rc_swn1_tbl1%";
