# Google BigQuery

## Set up a BigQuery warehouse

If you already have a BigQuery warehouse set up, you can skip this step.

* Visit <https://console.cloud.google.com>
* In the search bar, look for BigQuery
* Go through one of the guides to "Add your own data".
* You can test that things work by querying the resulting dataset table.

#### Configure a Google Service Account

A Google service account is a special kind of account that can be used by programs to access Google resources like a BigQuery data warehouse. You will use this service account to connect DataCamp DataLab to your BigQuery warehouse.

To set up a new Google Service Account, please refer to [this excellent guide](https://docs.openbridge.com/en/articles/1856793-how-to-set-up-google-bigquery-creating-and-configuring-service-accounts-in-google-cloud-console). At the end of it, you'll have the JSON credentials file that you can use to set up the BigQuery connection in DataLab.

## Set up a Google BigQuery connection

When inside a workbook, click **View** > **Databases**, then click the **+** icon and follow the on-screen instructions. Upload the Service Account JSON and hit "Connect".

For detailed instructions, see [connect-your-data-to-workspace](https://datalab-docs.datacamp.com/connect-to-data/connect-your-data-to-workspace "mention").

## Query the database

You can now query the BigQuery data warehouse with a [sql-cell](https://datalab-docs.datacamp.com/work/sql-cell "mention"). Select it in the **Select source** dropdown in the top left corner of a SQL cell, or select the sample BigQuery data warehouse.
