Integrate Live Google Spanner Data into Custom Business Apps Built in Power Apps

Use CData Connect Cloud to connect to Google Spanner data and integrate live Google Spanner data into apps built in Microsoft Power Apps.

Power Apps is a service for building and using custom business apps that connect to your data and work across the web and mobile — without the time and expense of custom software development. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Google Spanner data from the apps you build using Power Apps. This article shows how to connect to Connect Cloud from Power Apps and build an app based on live Google Spanner data.

CData Connect Cloud provides a pure SQL, cloud-to-cloud interface for Google Spanner, allowing you to easily integrate with live Google Spanner data in Power Apps — without replicating the data. CData Connect Cloud looks exactly like a SQL Server database to Power Apps and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Google Spanner, leveraging server-side processing to quickly return Google Spanner data.

Configure Google Spanner Connectivity for Power Apps

Connectivity to Google Spanner from Power Apps is made possible through CData Connect Cloud. To work with Google Spanner data from Power Apps, we start by creating and configuring a Google Spanner connection.

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "Google Spanner" from the Add Connection panel
  3. Google Spanner uses OAuth to authenticate. Click "Sign in" to authenticate with Google Spanner.
  4. Navigate to the Permissions tab in the Add Google Spanner Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Google Spanner data from Power Apps.

Connecting to CData Connect Cloud

To use Connect Cloud to integrate Google Spanner data into your Power Apps, you need a new SQL Server connection:

  1. Log in to Power Apps
  2. Click Dataverse -> Connections -> New connection
  3. Select SQL Server
  4. In the connection wizard:

    • Choose to connect directly
    • Set SQL server name to,14333
    • Set SQL database name to the name of the Google Spanner connection (e.g. GoogleSpanner1)
    • Set Username to a Connect Cloud user (e.g. [email protected])
    • Set Password to the PAT for the above user
    • Click Create

Building a Data-Centric App for Google Spanner Data

With the connection to Connect Cloud configured, you are ready to integrate live Google Spanner data into the apps you build in Power Apps.

  1. Log in to Power Apps
  2. Click Create and select "SQL"
  3. Select the SQL Server connection you created
  4. Search for or choose a table to work with
  5. Click Connect
  6. Customize the newly created app just like you would any other, including changing the layout and setting the fields exposed in BrowseScreen, DetailScreen, and EditScreen

At this point, you have an app with read and write access to live Google Spanner data that you can save and publish for use within your organization.
