Viewing Greenplum 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 Greenplum, you gain access to live Greenplum データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Greenplum データ. This article will walk through connecting to Greenplum using the Data Explorer.

Configure a Connection to Greenplum

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.

Greenplum に接続するには、Server、Port （デフォルトポートは5432）、およびDatabase 接続プロパティを設定して、サーバーへの認証に使用するUser とPassword を設定します。Database プロパティが指定されていない場合、CData 製品はユーザーのデフォルトデータベース（ユーザーと同じ名前になります）に接続します。

Connecting to Greenplum データ Using Data Explorer

You can create a simple application for displaying Greenplum データ by utilizing the CData FireDAC Components for Greenplum 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 Greenplum.
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.
