Build a Simple VCL Application for YouTube Analytics データ

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for YouTube Analytics, you gain access to live YouTube Analytics データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update YouTube Analytics データ. This article will walk through connecting to YouTube Analytics and creating a simple VCL application with the Form Designer.

Create a Connection to YouTube Analytics データ

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.

YouTube Analytics への接続には、OAuth 認証標準を使います。ユーザーアカウントまたはサービスアカウントで認証できます。組織全体のアクセススコープをCData 製品に許可するには、サービスアカウントが必要です。下記で説明するとおり、CData 製品はこれらの認証フローをサポートします。

ユーザー資格情報の接続プロパティを設定せずに接続できます。次を設定して、接続してください。ChannelId：YouTube チャンネルのId に設定。指定しない場合、認証されたユーザーのチャンネルのデータが返されます。ContentOwnerId：コンテンツ所有者のレポートを生成する場合に設定。接続すると、CData 製品はデフォルトブラウザでOAuth エンドポイントを開きます。ログインして、アプリケーションにアクセス許可を与えます。CData 製品がOAuth プロセスを完了します。

他のOAuth 認証フローについては、ヘルプドキュメントの「OAuth 認証の使用」を参照してください。

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to YouTube Analytics データ.

1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
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 YouTube Analytics.

Create VCL Applications with Connectivity to YouTube Analytics データ

Follow the procedure below to start executing queries to YouTube Analytics データ from a simple VCL application that displays the results of a query in a grid.

1. Drop a TFDConnection component onto the form and set the following properties:

   • ConnectionDefName: Select the FireDAC connection to YouTube Analytics データ.
   • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.

2. Drop a TFDQuery component onto the form and set the properties below:

   • Connection: Set this property to the TFDConnection component, if this component is not already specified.

   • SQL: Click the button in the SQL property and enter a query. For example:

     SELECT Snippet_Title, ContentDetails_ItemCount FROM Groups
   • Active: Set this property to true.

3. Drop a TDataSource component onto the form and set the following property:

   • DataSet: In the menu for this property, select the name of the TFDQuery component.

4. Drop a TDBGrid control onto the form and set the following property:

   • DataSource: Select the name of the TDataSource.
5. Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
