Viewing Hive Data in RAD Studio Data Explorer

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

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

Connecting to Hive Data Using Data Explorer

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

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

  3. Name the connection.
  4. Fill in the necessary connection parameters and click OK.
    Set the Server, Port, TransportMode, and AuthScheme connection properties to connect to Hive.

  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.
