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

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

Create a Profile for the ODBC Driver for Databricks

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

  1. If you have not already done so, create an ODBC DSN for Databricks. The DSN contains the connection properties required to connect to Databricks data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver. Required connection properties are the following:
    • Server
    • Port
    • TransportMode
    • HTTPPath
    • UseSSL
    • User
    • Password

    To connect to a Databricks cluster, set the properties as described below.

    Note: The needed values can be found in your Databricks instance by navigating to Clusters, and selecting the desired cluster, and selecting the JDBC/ODBC tab under Advanced Options.

    • Server: Set to the Server Hostname of your Databricks cluster.
    • HTTPPath: Set to the HTTP Path of your Databricks cluster.
    • Token: Set to your personal access token (this value can be obtained by navigating to the User Settings page of your Databricks instance and selecting the Access Tokens tab).
    See the help documentation for a guide to creating a Databricks DSN.
  2. In PowerBuilder, click Tools -> Database Painter.
  3. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  4. On the Connection tab, enter a name for the profile and select the Databricks DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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

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