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/). 

# STL\$1USERLOG
<a name="r_STL_USERLOG"></a>

Records details for the following changes to a database user:
+ Create user
+ Drop user
+ Alter user (rename)
+ Alter user (alter properties)

STL\$1USERLOG is visible only to superusers. For more information, see [Visibility of data in system tables and views](cm_chap_system-tables.md#c_visibility-of-data).

Some or all of the data in this table can also be found in the SYS monitoring view [SYS\$1USERLOG](SYS_USERLOG.md). The data in the SYS monitoring view is formatted to be easier to use and understand. We recommend that you use the SYS monitoring view for your queries.

## Table columns
<a name="r_STL_USERLOG-table-columns"></a>

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/redshift/latest/dg/r_STL_USERLOG.html)

## Sample queries
<a name="r_STL_USERLOG-sample-queries"></a>

The following example performs four user actions, then queries the STL\$1USERLOG view. 

```
create user userlog1 password 'Userlog1';
alter user userlog1 createdb createuser;
alter user userlog1 rename  to userlog2;
drop user userlog2;

select userid, username, oldusername, action, usecreatedb, usesuper from stl_userlog order by recordtime desc;
```

```
 userid |  username | oldusername |  action | usecreatedb | usesuper
--------+-----------+-------------+---------+-------------+----------
    108 | userlog2  |             | drop    |           1 |   1
    108 | userlog2  | userlog1    | rename  |           1 |   1
    108 | userlog1  |             | alter   |           1 |   1
    108 | userlog1  |             | create  |           0 |   0
 (4 rows)
```
