Connect to Azure Table Data from PowerBuilder


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

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

    AccessKey=myAccessKey;Account=myAccountName;

    Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

  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=Name}" Header="Name" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Azure Table 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.AzureTables.AzureTablesConnection conn conn = create System.Data.CData.AzureTables.AzureTablesConnection(connectionString) System.Data.CData.AzureTables.AzureTablesCommand comm comm = create System.Data.CData.AzureTables.AzureTablesCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.AzureTables.AzureTablesDataAdapter dataAdapter dataAdapter = create System.Data.CData.AzureTables.AzureTablesDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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