Rapidly Develop Greenplum-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 Greenplum data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Greenplum enables standards-based access to Greenplum. 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 Greenplum 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 Greenplum, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the default database for the authenticate user is used.

Use SQL to Interact with Greenplum

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 Greenplum), 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.
