Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# STV\$1MV\$1INFO
<a name="r_STV_MV_INFO"></a>

The STV\$1MV\$1INFO table contains a row for every materialized view, whether the data is stale, and state information. 

For more information about materialized views, see [Materialized views in Amazon Redshift](materialized-view-overview.md).

STV\$1MV\$1INFO is visible to all users. Superusers can see all rows; regular users can only list materialized views residing in schemas they have access to. For more information, see [Visibility of data insystem tables and views](https://docs.aws.amazon.com/redshift/latest/dg/cm_chap_system-tables.html#c_visibility-of-data).

## Sample query
<a name="r_STV_MV_INFO-sample-query"></a>

To view the state of all materialized views, run the following query. 

```
select * from stv_mv_info;
```

This query returns the following sample output. 

```
 db_name |       schema       |   name  | updated_upto_xid | is_stale | owner_user_name | state | autorefresh | autorewrite
---------+--------------------+---------+------------------+----------+-----------------+-------+-------------+------------
