Phoenix ODBC Driver

The Phoenix ODBC Driver is a powerful tool that allows you to connect with HBase through Apache Phoenix, directly from any applications that support ODBC connectivity.

Access Phoenix like you would a relational database - read, write, and update through a standard ODBC Driver interface.



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

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

Connect to Phoenix 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.

Connect to Apache Phoenix via the Phoenix Query Server. Set the Server and Port (if different from the default port) properties to connect to Apache Phoenix. The Server property will typically be the host name or IP address of the server hosting Apache Phoenix.

Authenticating to Apache Phoenix

By default, no authentication will be used (plain). If authentication is configured for your server, set AuthScheme to NEGOTIATE and set the User and Password properties (if necessary) to authenticate through Kerberos.

Create a Profile for the ODBC Driver for Phoenix

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Phoenix. In the Database Painter, you can use wizards and the UI to work with Phoenix 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 Phoenix DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Phoenix 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 Phoenix data into a DataWindow. You can add the following code to the open method:

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