Rapidly Develop Oracle-Driven Apps with Active Query Builder
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 Oracle data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Oracle enables standards-based access to Oracle. 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 Oracle 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.
To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:
- Port: The port used to connect to the server hosting the Oracle database.
- User: The user Id provided for authentication with the Oracle database.
- Password: The password provided for authentication with the Oracle database.
- Service Name: The service name of the Oracle database.
Use SQL to Interact with Oracle
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 Oracle), 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.
