Work with Live HCL Domino Data in Power Query

Power Query is a data transformation and data preparation engine. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to HCL Domino data from Power Query. This article shows how to connect to Connect Cloud from Power Query through Microsoft Excel and get live access to HCL Domino data for transformation and preparation.

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

Configure HCL Domino Connectivity for Power Query

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

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "HCL Domino" from the Add Connection panel
3. Enter the necessary authentication properties to connect to HCL Domino.

   Connecting to Domino

   To connect to Domino data, set the following properties:

   • URL: The host name or IP of the server hosting the Domino database. Include the port of the server hosting the Domino database. For example: http://sampleserver:1234/
   • DatabaseScope: The name of a scope in the Domino Web UI. The driver exposes forms and views for the schema governed by the specified scope. In the Domino Admin UI, select the Scopes menu in the sidebar. Set this property to the name of an existing scope.

   Authenticating with Domino

   Domino supports authenticating via login credentials or an Azure Active Directory OAuth application:

   Login Credentials

   To authenticate with login credentials, set the following properties:

   • AuthScheme: Set this to "OAuthPassword"
   • User: The username of the authenticating Domino user
   • Password: The password associated with the authenticating Domino user

   The driver uses the login credentials to automatically perform an OAuth token exchange.

   AzureAD

   This authentication method uses Azure Active Directory as an IdP to obtain a JWT token. You need to create a custom OAuth application in Azure Active Directory and configure it as an IdP. To do so, follow the instructions in the Help documentation. Then set the following properties:

   • AuthScheme: Set this to "AzureAD"
   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • OAuthClientId: The Client ID obtained when setting up the custom OAuth application.
   • OAuthClientSecret: The Client secret obtained when setting up the custom OAuth application.
   • CallbackURL: The redirect URI defined when you registered your app. For example: https://localhost:33333
   • AzureTenant: The Microsoft Online tenant being used to access data. Supply either a value in the form companyname.microsoft.com or the tenant ID.

     The tenant ID is the same as the directory ID shown in the Azure Portal's Azure Active Directory > Properties page.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add HCL Domino 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 HCL Domino data from Power Query.

Working with Live HCL Domino Data in Power Query

With the connection to Connect Cloud configured, you are ready to work with live HCL Domino data in Power Query.

1. In Microsoft Excel, open the Power Query Editor (from the Data ribbon, click Get Data -> Launch Power Query Editor)
2. Click New Source -> SQL Server
3. In the SQL Server database modal:
   • Set Server to tds.cdata.com,14333
   • (Optional) Set Database to the name of the HCL Domino connection (e.g. Domino1 )
4. In the SQL Server credentials modal, select "Database" and
   • Set User to your Connect Cloud username (e.g. [email protected] )
   • Set Password to the PAT for the above user
5. Click Connect
6. Select the table(s) you wish to work with in the Navigator and click "OK"

At this point, you have live access to HCL Domino data from Power Query for transformation and preparation.
