Google Cloud SQL is a fully managed relational database service from Google Cloud that handles provisioning, maintenance, and scaling of SQL Server databases without requiring you to manage the underlying infrastructure. It supports SQL Server 2017, 2019, and 2022 and is commonly used to power web applications, internal tools, and analytics pipelines hosted on Google Cloud. Connecting Google Cloud for SQL Server to Databox lets you pull data directly from your managed database, build datasets using SQL queries, and visualize business-critical figures alongside data from your other connected tools.
If you've already established a connection, you can reuse it to add new data sources to your Databox account.
Databox only reads data from your database — it never writes to it. Create a dedicated SQL Server login with SELECT-only permissions on the database you want to connect. You can run these commands using the Cloud SQL Studio query editor in the Google Cloud Console, or via a SQL Server client (such as SSMS or Azure Data Studio) connected to your instance.
CREATE LOGIN databox WITH PASSWORD = 'your_secure_password';
GO
USE your_database;
GO
CREATE USER databox FOR LOGIN databox;
GO
GRANT SELECT ON SCHEMA::dbo TO databox;
GOReplace your_database with the name of the database you want to connect, and your_secure_password with a strong password. If you need to grant access to additional schemas, repeat the GRANT SELECT ON SCHEMA statement for each one.
Databox connects to Cloud SQL over a public IP address. If your instance does not already have one assigned, enable it in the Google Cloud Console.
- In the Google Cloud Console, go to SQL and select your instance.
- Click Edit.
- Under Connections, expand Networking and ensure Public IP is enabled.
- Click Save to apply the change.
Cloud SQL controls inbound network access through an authorized networks list. Add the Databox IP address as an authorized network so it can reach your instance on port 1433.
- In the Google Cloud Console, go to SQL and select your instance.
- Click Edit.
- Under Connections > Networking > Authorized networks, click Add a network.
- In the Network field, enter
52.4.198.118/32. - Optionally enter a name (e.g.,
Databox) in the Name field. - Click Done, then click Save.
- In Databox, go to Data Sources > + New connection.
- Search for Google Cloud for SQL Server and click Connect.
- Fill in the connection form:
- Data source name — a label for this connection in Databox.
- Server Name — the public IP address of your Cloud SQL instance, found on the instance's Overview tab in the Google Cloud Console (e.g.,
34.123.45.67). - Port — the port your Cloud SQL instance listens on. The default for SQL Server is
1433. - Username — the SQL Server login name created in Step 1.
- Password — the password for that login.
- Database name (optional) — the specific database to connect to. Leave blank to connect at the server level.
- Timezone — the time zone used to interpret date values in query results. Defaults to
Etc/UTC.
- Click Connect.

The Google Cloud SQL for SQL Server integration supports the creation of datasets, which allow you to define and shape the specific data you want to use for reporting in Databox. Datasets make it easier to focus on the most relevant information, enabling you to filter, visualize, and analyze metrics across projects, teams, and clients without writing complex queries each time.
- Select a table: Pick the appropriate schema within that database.
- Select columns: Browse and select the specific columns (fields) from your tables or views to include in your dataset. These columns define the structure and content of your dataset.
For more advanced use cases, you can write a custom SQL query instead of selecting columns manually. This allows you to:
- Join multiple tables
- Apply filters and aggregations
- Format or transform data before importing it into Databox
Your query must return a valid tabular result to be used as a dataset.

FAQ
Does Databox support Cloud SQL Auth Proxy or private IP connections?
No. Databox connects to Cloud SQL over a public IP address only. The Cloud SQL Auth Proxy and private IP connectivity are not supported. Your instance must have a public IP address enabled and the Databox IP (52.4.198.118) must be listed in the instance's authorized networks.
What should I do if Databox cannot connect to my Cloud SQL instance?
Check the following in order:
- Public IP is enabled on the instance (under Edit > Connections > Networking).
- The Authorized networks list includes
52.4.198.118/32. - The SQL Server login was created at the server level and a corresponding user exists in the target database with
SELECTpermissions.
