Viewing Google Spanner Data in RAD Studio Data Explorer

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

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

Connecting to Google Spanner Data Using Data Explorer

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

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

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

    Google Spanner uses the OAuth authentication standard. To authenticate using OAuth, you can use the embedded credentials or register an app with Google.

    See the Getting Started guide in the CData driver documentation for more information.

  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: Customer) onto the form.

  7. Select the CustomerTable 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 Customer data.
