Connect to Teradata Data from PowerBuilder



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

This article demonstrates using the CData ADO.NET Provider for Teradata in PowerBuilder, showcasing the ease of use and compatibility of these standards-based controls across various platforms and development technologies that support Microsoft .NET, including Appeon PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Teradata to perform reads and writes.

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

    User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;

    To connect to Teradata, provide authentication information and specify the database server name.

    • User: Set this to the username of a Teradata user.
    • Password: Set this to the password of the Teradata user.
    • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
    • Port: Specify the port the server is running on.
    • Database: Specify the database name. If not specified, the default database is used.

  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=ProductId}" Header="ProductId" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Teradata 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.Teradata.TeradataConnection conn conn = create System.Data.CData.Teradata.TeradataConnection(connectionString) System.Data.CData.Teradata.TeradataCommand comm comm = create System.Data.CData.Teradata.TeradataCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Teradata.TeradataDataAdapter dataAdapter dataAdapter = create System.Data.CData.Teradata.TeradataDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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