How to view Cosmos DB data in RAD Studio Data Explorer using the CData FireDAC Components for Cosmos DB.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData FireDAC Components for Cosmos DB, you gain access to live Cosmos DB data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Cosmos DB data. This article will walk through connecting to Cosmos DB using the Data Explorer.

Connecting to Cosmos DB Data Using Data Explorer

You can create a simple application for displaying Cosmos DB data by utilizing the CData FireDAC Components for Cosmos DB and a new VCL Forms Application:

  1. Open the Data Explorer in RAD Studio and expand FireDAC.
  2. Right-click on CData Cosmos DB Data Source and click Add New Connection.

  3. Name the connection.
  4. Fill in the necessary connection parameters and click OK.

    To obtain the connection string needed to connect to a Cosmos DB account using the SQL API, log in to the Azure Portal, select Azure Cosmos DB, and select your account. In the Settings section, click Connection String and set the following values:

    • AccountEndpoint: The Cosmos DB account URL from the Keys blade of the Cosmos DB account
    • AccountKey: In the Azure portal, navigate to the Cosmos DB service and select your Azure Cosmos DB account. From the resource menu, go to the Keys page. Find the PRIMARY KEY value and set AccountKey to this value.

  5. Back in the Data Explorer, expand the tables for the connection.
  6. Create a new VCL Forms application and drag a table (for example: Customers) onto the form.

  7. Select the CustomersTable object on the form and set the Active property to true.
  8. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

  9. Arrange the TStringGrid on the form and run the application to see the Customers data.
