Use CData Connect AI to connect to live Lakebase data in the Power Pivot business intelligence tool.

This article will explain how to use CData Connect AI to present Lakebase data as OData services and then consume the data in Microsoft Excel's Power Pivot business intelligence tool. Follow the steps below to retrieve and edit Lakebase data in Power Pivot.

Connect to Lakebase from Power Pivot

To work with Lakebase data from Power Pivot, we need to connect to Lakebase from Connect AI, provide user access to the connection, and create a Workspace for the Lakebase data.

Connect to Lakebase from Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

  1. Log into Connect AI, click Sources, and then click Add Connection
    2. 👁 Adding a Connection
  2. Select "Lakebase" from the Add Connection panel
    3. 👁 Selecting a data source
  3. Enter the necessary authentication properties to connect to Lakebase. To connect to Databricks Lakebase, start by setting the following properties:
    • DatabricksInstance: The Databricks instance or server hostname, provided in the format instance-abcdef12-3456-7890-abcd-abcdef123456.database.cloud.databricks.com.
    • Server: The host name or IP address of the server hosting the Lakebase database.
    • Port (optional): The port of the server hosting the Lakebase database, set to 5432 by default.
    • Database (optional): The database to connect to after authenticating to the Lakebase Server, set to the authenticating user's default database by default.

    OAuth Client Authentication

    To authenicate using OAuth client credentials, you need to configure an OAuth client in your service principal. In short, you need to do the following:

    1. Create and configure a new service principal
    2. Assign permissions to the service principal
    3. Create an OAuth secret for the service principal

    For more information, refer to the Setting Up OAuthClient Authentication section in the Help documentation.

    OAuth PKCE Authentication

    To authenticate using the OAuth code type with PKCE (Proof Key for Code Exchange), set the following properties:

    • AuthScheme: OAuthPKCE.
    • User: The authenticating user's user ID.

    For more information, refer to the Help documentation.

  4. Click Save & Test
  5. Navigate to the Permissions tab in the Add Lakebase Connection page and update the User-based permissions. 👁 Updating permissions

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

  1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
  2. On the Settings page, go to the Access Tokens section and click Create PAT.
  3. Give the PAT a name and click Create. 👁 Creating a new PAT
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Configure Lakebase Endpoints for Power Pivot

After connecting to Lakebase, create a workspace for your desired table(s).

  1. Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace). 👁 The Workspaces page.
    👁 Adding a new Workspace.
  2. Click Add to add new assets to the Workspace.
  3. Select the Lakebase connection (e.g. Lakebase1) and click Next. 👁 Selecting an Asset (Salesforce is shown).
  4. Select the table(s) you wish to work with and click Confirm. 👁 Selecting Tables (Salesforce is shown).
  5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

With the connection, PAT, and Workspace configured, you are ready to connect to Lakebase data from Power Pivot.

Import Lakebase Tables in Power Pivot

Follow the steps below to import tables that can be refreshed on demand:

  1. In Excel, click Data -> Get Data -> From Other Sources -> From OData Feed 👁 Starting the OData connection.
  2. Fill out the OData feed URL (e.g. https://cloud.cdata.com/api/odata/{workspace_name}) 👁 The URL of the OData endpoint for Connect AI.
  3. On the next screen, select Basic and configure the username and password. Password will be your PAT. 👁 Authenticating with Connect AI

  4. Select the tables that you would like to import into Excel 👁 Selecting tables (Salesforce is shown.)

  5. After selecting your table(s) and clicking Load, you should see the data appear in an Excel spreadsheet 👁 Loading tables (Salesforce is shown.)

  6. Now, click the Power Pivot tab on the ribbon, and then select Add to Data Model. 👁 Loading data into Power Pivot (Salesforce is shown.)
    This can now work with your Lakebase data in Power Pivot.
