从补丁 198 开始，Amazon Redshift 将不再支持创建新的 Python UDF。现有的 Python UDF 将继续正常运行至 2026 年 6 月 30 日。有关更多信息，请参阅[博客文章](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/)。 # SYS\$1MV\$1STATE 结果包括有关所有实体化视图的状态的信息。这包括基表信息、架构属性和有关最近事件（例如删除列）的信息。 SYS\$1MV\$1STATE 对所有用户均可见。超级用户可以查看所有行；普通用户只能查看其自己的数据。有关更多信息，请参阅 [系统表和视图中的数据可见性](cm_chap_system-tables.md#c_visibility-of-data)。 ## 表列 [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/zh_cn/redshift/latest/dg/SYS_MV_STATE.html) ## 示例查询 以下查询显示了实体化视图状态。 ``` select * from sys_mv_state; ``` 查询返回以下示例输出： ``` user_id | transaction_id | database_name | event_desc | start_time | base_table_database_name | base_table_schema | base_table_name | mv_schema | mv_name | state ---------+----------------+---------------+-----------------------------+----------------------------+--------------------------+-------------------+---------------------+-------------+----------------------------+-------------- 106 | 12720 | tickit_db | TRUNCATE | 2023-07-26 14:59:12.788268 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_a1f3f862 | Recompute 106 | 12724 | tickit_db | ALTER TABLE ALTER DISTSTYLE | 2023-07-26 14:59:51.409014 | tickit_db | mv_schema | test_table_58102435 | mv_schema | materialized_view_ca746631 | Recompute 106 | 12720 | tickit_db | Column was renamed | 2023-07-26 14:59:12.822928 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_5750a8d4 | Unrefreshable 106 | 12727 | tickit_db | Table was renamed | 2023-07-26 15:00:08.051244 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_5750a8d4 | Unrefreshable 106 | 12720 | tickit_db | Column was renamed | 2023-07-26 14:59:12.857755 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_5750a8d4 | Unrefreshable 106 | 12727 | tickit_db | Table was renamed | 2023-07-26 15:00:08.051358 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_5ef0d754 | Unrefreshable 106 | 12720 | tickit_db | TRUNCATE | 2023-07-26 14:59:12.788159 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_5750a8d4 | Recompute 106 | 12720 | tickit_db | Column was renamed | 2023-07-26 14:59:12.857799 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_a1f3f862 | Unrefreshable 106 | 12720 | tickit_db | TRUNCATE | 2023-07-26 14:59:12.788327 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_5ef0d754 | Recompute 106 | 12727 | tickit_db | ALTER TABLE ALTER SORTKEY | 2023-07-26 15:00:08.006235 | tickit_db | mv_schema | test_table_58102435 | mv_schema | materialized_view_ca746631 | Recompute 106 | 12720 | tickit_db | Column was renamed | 2023-07-26 14:59:12.82297 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_a1f3f862 | Unrefreshable 106 | 12727 | tickit_db | Table was renamed | 2023-07-26 15:00:08.051321 | tickit_db | mv_schema | test_table_95d6d861 | mv_schema | materialized_view_a1f3f862 | Unrefreshable ```
