Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the blog post that was published on June 30, 2025.

SVV_REDSHIFT_FUNCTIONS

Use SVV_REDSHIFT_FUNCTIONS to view a list of all functions that a user has access to. This set of functions includes the functions on the cluster and the functions from datashares provided by remote clusters.

SVV_REDSHIFT_FUNCTIONS 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.

For more information about best practices when querying system tables and views, see Querying System Tables.

Note

Use the SHOW FUNCTIONS command for function discovery. SHOW FUNCTIONS 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.

Sample query

The following example returns the output of SVV_REDSHIFT_FUNCTIONS.

SELECT *
FROM svv_redshift_functions
WHERE database_name = 'tickit_db'
    AND SCHEMA_NAME = 'public'
ORDER BY function_name
LIMIT 5;
