Rapidly Develop Stack Exchange-Driven Apps with Active Query Builder

Leverage the Active Query Builder SQL interface and .NET data access to create data-driven WinForms and ASP.NET apps backed by Stack Exchange.

Write standard .NET to expose Stack Exchange data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Stack Exchange enables standards-based access to Stack Exchange. 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 Stack Exchange 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.

Start by setting the Profile connection property to the location of the Stack Exchange Profile on disk (e.g. C:\profiles\StackExchange.apip). Next, set the ProfileSettings connection property to the connection string for Stack Exchange (see below).

Stack Exchange API Profile Settings

Register an application on StackApps to obtain an API Key. The Site property specifies which Stack Exchange site to query (e.g., stackoverflow).

Use SQL to Interact with Stack Exchange

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

  1. Open Active Query Builder for .NET WinForms. ๐Ÿ‘ Opening Active Query Builder.
  2. In the new Windows Forms project go to the "File" menu and click "Connect..."
  3. Under Database Connections, click "Add..." ๐Ÿ‘ Adding a new Connection.
  4. Set your desired Connection Name (e.g. CData Stack Exchange), set Connection Type to "ODBC" and locate your previously configured DSN in the "User/System" DSN dropdown. ๐Ÿ‘ Selecting a previously configured DSN (Amazon Athena is shown).
  5. Click "OK" to save the new connection.
  6. Back in the Database Connection wizard, select the newly created connection and click "OK." ๐Ÿ‘ A newly added Connection (Amazon Athena is shown).
  7. Click "File" > "New Query" to create a QueryBuilder

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.
