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/). 

# query\$1group
<a name="r_query_group"></a>

## Values (default in bold)
<a name="r_query_group-values"></a>

No default; the value can be any character string. 

## Description
<a name="r_query_group-description"></a>

Applies a user-defined label to a group of queries that are run during the same session. This label is captured in the query logs. You can use it to constrain results from the STL\$1QUERY and STV\$1INFLIGHT tables and the SVL\$1QLOG view. For example, you can apply a separate label to every query that you run to uniquely identify queries without having to look up their IDs. 

This parameter doesn't exist in the server configuration file and must be set at runtime with a SET command. Although you can use a long character string as a label, the label is truncated to 30 characters in the LABEL column of the STL\$1QUERY table and the SVL\$1QLOG view (and to 15 characters in STV\$1INFLIGHT). 

In the following example, query\$1group is set to **Monday**, then several queries are run with that label.

```
set query_group to 'Monday';
SET
select * from category limit 1;
...
...
select query, pid, substring, elapsed, label
from svl_qlog where label ='Monday'
order by query;

query | pid  |        substring                   |  elapsed  | label
------+------+------------------------------------+-----------+--------
789   | 6084 | select * from category limit 1;    | 65468     | Monday
790   | 6084 | select query, trim(label) from ... | 1260327   | Monday
791   | 6084 | select * from svl_qlog where ..    | 2293547   | Monday
792   | 6084 | select count(*) from bigsales;     | 108235617 | Monday
...
