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/).
# SYS\$1LOAD\$1DETAIL
Returns information to track or troubleshoot a data load.
This view records the progress of each data file as it is loaded into a database table.
This view 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).
## Table columns
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/redshift/latest/dg/SYS_LOAD_DETAIL.html)
## Sample queries
The following example returns details for the last COPY operation.
```
select query_id, trim(file_name) as file, record_time
from sys_load_detail
where query_id = pg_last_copy_id();
query_id | file | record_time
----------+----------------------------------+----------------------------
28554 | s3://dw-tickit/category_pipe.txt | 2013-11-01 17:14:52.648486
(1 row)
```
The following query contains entries for a fresh load of the tables in the TICKIT database:
```
select query_id, trim(file_name), record_time
from sys_load_detail
where file_name like '%tickit%' order by query_id;
query_id | btrim | record_time
----------+--------------------------+----------------------------

The fact that a record is written to the log file for this system view does not mean that the load committed successfully as part of its containing transaction. To verify load commits, query the STL\$1UTILITYTEXT view and look for the COMMIT record that corresponds with a COPY transaction. For example, this query joins SYS\$1LOAD\$1DETAIL and STL\$1QUERY based on a subquery against STL\$1UTILITYTEXT:
```
select l.query_id,rtrim(l.file_name),q.transaction_id
from sys_load_detail l, sys_query_text q
where l.query_id=q.query_id
and exists
(select xid from stl_utilitytext where xid=q.transaction_id and rtrim("text")='COMMIT');
query_id | rtrim | transaction_id
