Viewing OData Services in RAD Studio Data Explorer

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

Configure a Connection to OData

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

OData ソースへの接続には、OData サーバーのルートURI もしくはOData サービスのファイルをURL に指定します。Authentication セクションでは、User およびPassword を設定します。

Connecting to OData Services Using Data Explorer

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

1. Open the Data Explorer in RAD Studio and expand FireDAC.
2. Right-click the ODBC Data Source node in the Data Explorer.
3. Click Add New Connection.
4. Enter a name for the connection.
5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for OData.
6. Back in the Data Explorer, expand the tables for the connection.

7. Create a new VCL Forms application and drag a table (for example: Orders) onto the form.

8. Select the OrdersTable object on the form and set the Active property to true.

9. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

10. Arrange the TStringGrid on the form and run the application to see the Orders data.
