google-big-queryHow do I use Google BigQuery Sandbox?

Google BigQuery Sandbox is a free, interactive environment for exploring and querying public datasets using BigQuery. It allows users to access a variety of public datasets and query them using standard SQL.

To use Google BigQuery Sandbox, users must first create a Google Cloud Platform (GCP) project. This can be done by visiting the Google Cloud Platform Console. Once the project is created, users can enable the BigQuery API.

Next, users must select the BigQuery Sandbox from the GCP Console. This will open the BigQuery Sandbox web UI. From here, users can select from a variety of public datasets and query them using standard SQL.

Example code

SELECT
  name,
  SUM(number) as total_number
FROM
  `bigquery-public-data.usa_names.usa_1910_current`
GROUP BY
  name
ORDER BY
  total_number DESC
LIMIT
  10
