Connecting Python and ClickHouse with ADBC

Tip

If you already have a ClickHouse instance running, skip the steps to set up and clean up ClickHouse.

Start a ClickHouse instance:

docker run -d --rm --name some-clickhouse-server -p 8123:8123 -e CLICKHOUSE_USER=user -e CLICKHOUSE_PASSWORD=pass clickhouse/clickhouse-server

Install the ClickHouse ADBC driver:
```
dbc install clickhouse
```
Customize the Python script main.py as needed
- Change the connection arguments in db_kwargs
  - Format uri according to the ClickHouse HTTP interface, or keep it as is
- If you changed which database you're connecting to, also change the SQL SELECT statement in cursor.execute()
Run the Python script:
```
uv run main.py
```

Stop the Docker container running ClickHouse:

docker stop some-clickhouse-server
