Twitter ODBC Driver を使って、ODBC 接続をサポートするあらゆるアプリケーション・ツールからTwitter データに連携。

Twitter ODBC ドライバーを使って、データベースへのクエリと同じ感覚で、簡単にリアルタイムでツイート、フォロー、メッセージ、検索 などにアクセスできます。

This article demonstrates how to use the CData ODBC Driver for Twitter to connect to Twitter data and execute queries in PowerBuilder.

The CData ODBC Driver for Twitter can be used from any platform or development technology that supports ODBC, including Sybase PowerBuilder. This article shows how to connect to Twitter data and execute queries from the Database Painter and controls such as the DataWindow.


Create a Profile for the ODBC Driver for Twitter

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Twitter. In the Database Painter, you can use wizards and the UI to work with Twitter data.

  1. If you have not already done so, create an ODBC DSN for Twitter. The DSN contains the connection properties required to connect to Twitter data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver. Required connection properties are the following:

    すべてのテーブルには認証が必要です。OAuth を使用してTwitter で認証する必要があります。OAuth では認証するユーザーにブラウザでTwitter との通信を要求します。詳しくは、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。

    See the help documentation for a guide to creating a Twitter DSN.
  2. In PowerBuilder, click Tools -> Database Painter.
  3. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  4. On the Connection tab, enter a name for the profile and select the Twitter DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Twitter Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Twitter data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Twitter Source'" CONNECT USING SQLCA; dw_tweets.SetTransObject(SQLCA); dw_tweets.Retrieve();
