Viewing Azure Analysis Services データ in RAD Studio Data Explorer

How to view Azure Analysis Services データ in RAD Studio Data Explorer using the CData ODBC Driver for Azure Analysis Services.

最終更新日：2023-06-12

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

Configure a Connection to Azure Analysis Services

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.

Azure Analysis Services（AAS）接続プロパティの取得・設定方法

接続するには、認証に加えて、Url プロパティを有効なAzure Analysis Services サーバー（例えばasazure://southcentralus.asazure.windows.net/server）に設定します。必要に応じて、Database プロパティを設定して、サーバー上のどのAzure データベースに接続するかを指定できます。

Azure Analysis Services はOAuth 認証標準を使用します。CData 製品では組込みOAuth が利用できるので、接続プロパティを設定することなく接続を試行するだけで、ブラウザ経由でAAS に認証できます。詳しい設定方法については、ヘルプドキュメントの「Azure Analysis Services への認証」セクションを参照してください。

Connecting to Azure Analysis Services データ Using Data Explorer

You can create a simple application for displaying Azure Analysis Services データ by utilizing the CData FireDAC Components for Azure Analysis Services and a new VCL Forms Application:

Open the Data Explorer in RAD Studio and expand FireDAC.
Right-click the ODBC Data Source node in the Data Explorer.
Click Add New Connection.
Enter a name for the connection.
In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Azure Analysis Services.
Back in the Data Explorer, expand the views for the connection.
Create a new VCL Forms application and drag a view (for example: Customer) onto the form.
Select the CustomerView object on the form and set the Active property to true.
Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).
Arrange the TStringGrid on the form and run the application to see the Customer data.
