Executing a sample query

After you log in, run the following SQL query:

SELECT
  date, project, count(*) as downloads
FROM 'https://motherduck-demo.s3.amazonaws.com/pypi_downloads.parquet'
GROUP BY date, project
ORDER BY date desc;

MotherDuck executes this query in the cloud. Query results are saved into your browser into an interactive panel for fast data exploration with data sorting, filtering, and pivoting.

Write queries with Autocomplete

MotherDuck Web UI supports autocomplete. As you write SQL in the UI, on every keystroke autocomplete brings up query syntax suggestions. You can turn off autocomplete in Web UI settings, found under the gear icon in top right.
