Rapidly Develop Impala-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 Impala data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Impala enables standards-based access to Impala. 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 Impala 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.

In order to connect to Apache Impala, set the Server, Port, and ProtocolVersion. You may optionally specify a default Database. To connect using alternative methods, such as NOSASL, LDAP, or Kerberos, refer to the online Help documentation.

Use SQL to Interact with Impala

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 Impala), 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.

The Impala ODBC Driver is a powerful tool that allows you to connect with live data from Impala, directly from any applications that support ODBC connectivity.

Access Impala data like you would a database - read, write, and update Impala data, etc. through a standard ODBC Driver interface.
