Viewing Teradata データ in RAD Studio Data Explorer

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

Configure a Connection to Teradata

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.

Teradata に接続するには、次の認証情報を提供し、データベースサーバー名を指定します。

• User: Teradata ユーザーのユーザー名に設定。
• Password: Teradata ユーザーのパスワードに設定。
• DataSource: Teradata サーバー名、DBC 名、またはTDPID を指定。
• Port: サーバーが実行されているポートを指定。
• Database: データベース名を指定。指定されない場合は、CData 製品はデフォルトデータベースに接続されます。

Connecting to Teradata データ Using Data Explorer

You can create a simple application for displaying Teradata データ by utilizing the CData FireDAC Components for Teradata 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 Teradata.
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: NorthwindProducts) onto the form.

8. Select the NorthwindProductsTable 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 NorthwindProducts data.
