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/). 

# SVV\_REDSHIFT\_SCHEMAS
<a name="r_SVV_REDSHIFT_SCHEMAS"></a>

Use SVV\_REDSHIFT\_SCHEMAS to view a list of all schemas that a user has access to. This set of schemas includes the schemas on the cluster and the schemas from datashares provided by remote clusters. 

SVV\_REDSHIFT\_SCHEMAS 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).

For more information about best practices when querying system tables and views, see [Querying System Tables](https://docs.aws.amazon.com/redshift/latest/mgmt/discovering-metadata-system-tables.html).

**Note**  
Use the [SHOW SCHEMAS](r_SHOW_SCHEMAS.md) command for schema discovery. SHOW SCHEMAS works consistently across local, datashare, and external catalog contexts and is updated as new features are released. For more information, see [Best practices for discovering metadata](https://docs.aws.amazon.com/redshift/latest/mgmt/best-practices-discovering-metadata.html).

## Table columns

| Column name  | Data type  | Description  | 
| --- | --- | --- | 
| database\_name | varchar(128) | The name of the database where a specified schema exists. | 
| schema\_name | varchar(128) | The namespace or schema name. | 
| schema\_owner | integer | The internal user ID of the schema owner. |

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

The following example returns the output of SVV\_REDSHIFT\_SCHEMAS.

```
SELECT *
FROM svv_redshift_schemas
WHERE database_name = 'tickit_db'
ORDER BY database_name,
    SCHEMA_NAME;

database_name |    schema_name     | schema_owner | schema_type | schema_acl | schema_option
--------------+--------------------+--------------+-------------+------------+---------------
   tickit_db  |       public       |       1      |    shared   |            |
```
