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/)。
# SVL\$1MV\$1REFRESH\$1STATUS
SVL\$1MV\$1REFRESH\$1STATUS 视图包含与具体化视图的刷新活动相对应的一行。
有关具体化视图的更多信息，请参阅[Amazon Redshift 中的实体化视图](materialized-view-overview.md)。
SVL\$1MV\$1REFRESH\$1STATUS 对所有用户可见。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)。
此表中的部分或全部数据也可以在 SYS 监控视图 [SYS\$1MV\$1REFRESH\$1HISTORY](SYS_MV_REFRESH_HISTORY.md) 中找到。SYS 监控视图中的数据经过格式化处理，便于使用和理解。我们建议您使用 SYS 监控视图进行查询。
## 表列

## 示例查询
要查看具体化视图的刷新状态，请运行以下查询。
```
select * from svl_mv_refresh_status;
```
此查询返回以下示例输出：
```
