Connect to HBase Data from PowerBuilder


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

This article demonstrates using the CData ADO.NET Provider for HBase 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 HBase 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:

    Server=127.0.0.1;Port=8080;

    Set the Port and Server to connect to Apache HBase.

  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=CustomerName}" Header="CustomerName" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for HBase 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.ApacheHBase.ApacheHBaseConnection conn conn = create System.Data.CData.ApacheHBase.ApacheHBaseConnection(connectionString) System.Data.CData.ApacheHBase.ApacheHBaseCommand comm comm = create System.Data.CData.ApacheHBase.ApacheHBaseCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.ApacheHBase.ApacheHBaseDataAdapter dataAdapter dataAdapter = create System.Data.CData.ApacheHBase.ApacheHBaseDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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