Facebook ODBC Driver

Facebook ODBC ドライバーは、ODBC 接続をサポートする任意のアプリケーションからリアルタイムなFacebook アカウントデータに直接接続できるパワフルなツールです。標準のODBC ドライバーインタフェースを使用して、データベースのようにFacebook データにアクセスし、Facebook の投稿、グループ、イベント、スポットなどの読み、書き、更新を実行できます。



Leverage the Active Query Builder SQL interface builder and the ease of .NET data access to create data-driven WinForms and ASP.NET apps.

Write standard .NET to expose Facebook data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Facebook enables standards-based access to Facebook. This integration uses the Microsoft ADO.NET Provider for ODBC as a bridge between the ODBC Driver and the Active Query Builder objects to build a visual SQL composer.

Connect to Facebook as an ODBC Data Source

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.

Facebook はユーザー認証にOAuth 標準を使用しています。 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。 接続すると、本製品はデフォルトブラウザでFacebook OAuth エンドポイントを開きます。ログインして、本製品にアクセス許可を与えます。本製品が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。

Use SQL to Interact with Facebook

Follow the steps below to create a WinForms visual query builder.

  1. In a new Windows Forms project, drag the QueryBuilder from the Toolbox onto the form.
  2. Add a reference to ActiveQueryBuilder.ODBCMetadataProvider.
  3. Add an OdbcConnection and set the connection string to the DSN that you created in the first section. OdbcConnection connection = new OdbcConnection(); connection.ConnectionString = "DSN=Facebook"
  4. Initialize ODBCMetadataProvider and GeneralSyntaxProvider instances and set the Connection property of the ODBCMetadataProvider object to the OdbcConnection. GenericSyntaxProvider syntaxProvider = new GenericSyntaxProvider(); ODBCMetadataProvider metadataProvider = new ODBCMetadataProvider(); metadataProvider.Connection = connection;
  5. Set the corresponding MetadataProvider and SyntaxProvider properties of the QueryBuilder object. queryBuilder1.MetadataProvider = metadataProvider; queryBuilder1.SyntaxProvider = syntaxProvider;
  6. Call the InitiatelizeDatabaseSchemaTree method of the QueryBuilder class to retrieve Facebook metadata and generate a tree view of Facebook tables. queryBuilder1.InitializeDatabaseSchemaTree();
  7. After creating the QueryBuilder, connect it to a TextBox or, as we use, the ActiveQueryBuilder SQLTextEditor: Drag and drop an SQLTextEditor onto the designer.

  8. Add the following code to the Validating event for the SQLTextEditor: private void sqlTextEditor1_Validating(object sender, CancelEventArgs e) { try { // Update the query builder with manually edited query text: queryBuilder1.SQL = sqlTextEditor1.Text; } catch (SQLParsingException ex) { e.Cancel = true; // Set caret to error position sqlTextEditor1.SelectionStart = ex.ErrorPos.pos; // Report error MessageBox.Show(ex.Message, "Parsing error"); } }
  9. Add the following to the SQLUpdated event: private void queryBuilder1_SQLUpdated(object sender, EventArgs e) { sqlTextEditor1.Text = queryBuilder1.FormattedSQL; }
  10. You can now build queries visually: Double-click a table in the Columns Pane Area and an entity/relationship diagram is displayed in the Query Building Area. Columns that you select in the diagram are added to the query.
