Connect to DataRobot Data from PowerBuilder

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

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

Create a Profile for the ODBC Driver for DataRobot

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

  1. If you have not already done so, create an ODBC DSN for DataRobot. The DSN contains the connection properties required to connect to DataRobot 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:
    • PredictionInstance
    • DataFile
    • DataRobotKey
    • User
    • Password

    To connect to DataRobot, the following connection properties are required: User, Password, and PredictionInstance. DataRobotKey may also be required depending on your type of DataRobot predictions instance. If using the Predictions API, DataFile is required. The CSV DataFile should include a header row as the first row of the datafile. APIKey is not required, but can be supplied. If not supplied, the driver will handle obtaining an APIKey.

    User, DataRobotKey, and APIKey are the credentials for the DataRobot account.

    ProjectID, DataFile, and ModelId are the parameters for the project, dataset, and model type.

    See the help documentation for a guide to creating a DataRobot 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 DataRobot DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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

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