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/). 

# SYS\$1PROCEDURE\$1CALL
SYS\$1PROCEDURE\$1CALL

Use the SYS\$1PROCEDURE\$1CALL view to get information about stored procedure calls, including start time, end time, status of a stored procedure call, and call hierarchy for nested stored procedure calls. Each stored procedure call receives a query ID.

SYS\$1PROCEDURE\$1CALL 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
Sample queries

The following query returns a nested stored procedure call hierarchy.

```
select query_id, datediff(seconds, start_time, end_time) as elapsed_time, status, trim(query_text) as call, caller_procedure_query_id from sys_procedure_call;
```

Sample output.

```
 query_id | elapsed_time | status  |                       call                       | caller_procedure_query_id 
----------+--------------+---------+--------------------------------------------------+---------------------------
