Connect to Hive Data from PowerBuilder
This article demonstrates how to access Hive data from Appeon PowerBuilder using the CData ADO.NET Provider for Hive.
This article demonstrates using the CData ADO.NET Provider for Hive 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 Hive to perform reads and writes.
- 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=10000;TransportMode=BINARY;
Set the Server, Port, TransportMode, and AuthScheme connection properties to connect to Hive.
- Add the DataGrid control from the .NET controls.
-
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=City}" Header="City" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid> - Add a reference to the CData ADO.NET Provider for Hive 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.ApacheHive.ApacheHiveConnection conn
conn = create System.Data.CData.ApacheHive.ApacheHiveConnection(connectionString)
System.Data.CData.ApacheHive.ApacheHiveCommand comm
comm = create System.Data.CData.ApacheHive.ApacheHiveCommand(command, conn)
System.Data.DataTable table
table = create System.Data.DataTable
System.Data.CData.ApacheHive.ApacheHiveDataAdapter dataAdapter
dataAdapter = create System.Data.CData.ApacheHive.ApacheHiveDataAdapter(comm)
dataAdapter.Fill(table)
datagrid1.ItemsSource=table.DefaultView
The code above can be used to bind data from the specified query to the DataGrid.
