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/). 

# SVL\$1MV\$1REFRESH\$1STATUS
<a name="r_SVL_MV_REFRESH_STATUS"></a>

The SVL\$1MV\$1REFRESH\$1STATUS view contains a row for the refresh activity of materialized views. 

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

SVL\$1MV\$1REFRESH\$1STATUS is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see [Visibility of data in system tables and views](cm_chap_system-tables.md#c_visibility-of-data).

Some or all of the data in this table can also be found in the SYS monitoring view [SYS\$1MV\$1REFRESH\$1HISTORY](SYS_MV_REFRESH_HISTORY.md). The data in the SYS monitoring view is formatted to be easier to use and understand. We recommend that you use the SYS monitoring view for your queries.

## Table columns

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/redshift/latest/dg/r_SVL_MV_REFRESH_STATUS.html)

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

To view the refresh status of materialized views, run the following query. 

```
select * from svl_mv_refresh_status;
```

This query returns the following sample output: 

```
 db_name | userid |  schema   |  name   |  xid  |         starttime          |          endtime           |                        status                                                       |  refresh_type | consumer_account | consumer_region | consumer_namespace
