Connect to DataRobot Data from PowerBuilder

This article demonstrates how to access DataRobot data from PowerBuilder using the CData ADO.NET Provider for DataRobot.

The CData ADO.NET providers are easy-to-use, standards-based controls that can be used from any platform or development technology that supports Microsoft .NET, including PowerBuilder. This article shows how to use the CData ADO.NET Provider for DataRobot in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for DataRobot to retrieve data.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

    PredictionInstance=myinstance.orm.datarobot.com;DataFile=PATH\TO\input_file.csv;DataRobotKey=123-abc-456-def;User=username;Password=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.

  2. Add the DataGrid control from the .NET controls.
  3. Configure the columns of the DataGrid control. Below are several columns from the Account table: <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for DataRobot assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.DataRobot.DataRobotConnection conn conn = create System.Data.CData.DataRobot.DataRobotConnection(connectionString) System.Data.CData.DataRobot.DataRobotCommand comm comm = create System.Data.CData.DataRobot.DataRobotCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.DataRobot.DataRobotDataAdapter dataAdapter dataAdapter = create System.Data.CData.DataRobot.DataRobotDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
