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://amazonaws-china.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# SVV\_ALL\_TABLES
<a name="r_SVV_ALL_TABLES"></a>

Use SVV\_ALL\_TABLES to view a union of Amazon Redshift tables as shown in SVV\_REDSHIFT\_TABLES and the consolidated list of all external tables from all external schemas. For information about Amazon Redshift tables, see [SVV\_REDSHIFT\_TABLES](r_SVV_REDSHIFT_TABLES.md).

SVV\_ALL\_TABLES 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).

## Sample queries

The following example returns the output of SVV\_ALL\_TABLES.

```
SELECT *
FROM svv_all_tables
WHERE database_name = 'tickit_db'
ORDER BY TABLE_NAME,
    SCHEMA_NAME
LIMIT 5;

 database_name | schema_name |        table_name        | table_type | table_acl | remarks
---------------+-------------+--------------------------+------------+-----------+---------
   tickit_db   |    public   | tickit_category_redshift |    TABLE   |           |
   tickit_db   |    public   |   tickit_date_redshift   |    TABLE   |           |
   tickit_db   |    public   |   tickit_event_redshift  |    TABLE   |           |
   tickit_db   |    public   | tickit_listing_redshift  |    TABLE   |           |
   tickit_db   |    public   |   tickit_sales_redshift  |    TABLE   |           |
```

If the table\_acl value is null, no access privileges have been explicitly granted to the corresponding table.
