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

Write standard .NET to expose Flowlu data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Flowlu enables standards-based access to Flowlu. 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 Flowlu 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 Flowlu Profile on disk (e.g. C:\profiles\Flowlu.apip). Next, set the ProfileSettings connection property to the connection string for Flowlu (see below).

Flowlu API Profile Settings

In your Flowlu account, navigate to System Settings > API Settings > Create to generate an API key. Your Company name is the subdomain from your Flowlu account URL.

Use SQL to Interact with Flowlu

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

  1. Open Active Query Builder for .NET WinForms.
  2. In the new Windows Forms project go to the "File" menu and click "Connect..."
  3. Under Database Connections, click "Add..."
  4. Set your desired Connection Name (e.g. CData Flowlu), set Connection Type to "ODBC" and locate your previously configured DSN in the "User/System" DSN dropdown.
  5. Click "OK" to save the new connection.
  6. Back in the Database Connection wizard, select the newly created connection and click "OK."
  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.
