Apache Cassandra Icon Cassandra ODBC Driver

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

Access Cassandra data like you would a database - read, write, and update NoSQL tables through a standard ODBC Driver interface.

Connect to Cassandra Data from PowerBuilder


This article demonstrates how to use the CData ODBC Driver for Cassandra to connect to Cassandra data and execute queries in PowerBuilder.

The CData ODBC Driver for Cassandra can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to Cassandra data and execute queries from the Database Painter and controls such as the DataWindow.

Connect to Cassandra 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.

Set the Server, Port, and Database connection properties to connect to Cassandra. Additionally, to use internal authentication set the User and Password connection properties.

Create a Profile for the ODBC Driver for Cassandra

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Cassandra. In the Database Painter, you can use wizards and the UI to work with Cassandra data.

  1. In PowerBuilder, click Tools -> Database Painter.
  2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  3. On the Connection tab, enter a name for the profile and select the Cassandra DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Cassandra Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Cassandra data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Cassandra Source'" CONNECT USING SQLCA; dw_customer.SetTransObject(SQLCA); dw_customer.Retrieve();
