Rapidly Develop OpenWeatherMap-Driven Apps with Active Query Builder
Write standard .NET to expose OpenWeatherMap data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for OpenWeatherMap enables standards-based access to OpenWeatherMap. 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 OpenWeatherMap 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.
Using API Key Authentication
To obtain an API key, sign up for a free account at https://openweathermap.org/api and navigate to the API keys section of your dashboard. Copy your API key for use in the connection configuration.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to APIKey.
- APIKey: Set this to your OpenWeatherMap API key.
Use SQL to Interact with OpenWeatherMap
Follow the steps below to create a WinForms visual query builder.
- Open Active Query Builder for .NET WinForms.
- In the new Windows Forms project go to the "File" menu and click "Connect..."
- Under Database Connections, click "Add..."
- Set your desired Connection Name (e.g. CData OpenWeatherMap), set Connection Type to "ODBC" and locate your previously configured DSN in the "User/System" DSN dropdown.
- Click "OK" to save the new connection.
- Back in the Database Connection wizard, select the newly created connection and click "OK."
- 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.
