Connect to Azure Data Catalog Data from PowerBuilder


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

This article demonstrates using the CData ADO.NET Provider for Azure Data Catalog 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 Data Catalog to retrieve data.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties.

    You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

      CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

    Connect Using OAuth Authentication

    You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

  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=DslAddressDatabase}" Header="DslAddressDatabase" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Azure Data Catalog 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.AzureDataCatalog.AzureDataCatalogConnection conn conn = create System.Data.CData.AzureDataCatalog.AzureDataCatalogConnection(connectionString) System.Data.CData.AzureDataCatalog.AzureDataCatalogCommand comm comm = create System.Data.CData.AzureDataCatalog.AzureDataCatalogCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.AzureDataCatalog.AzureDataCatalogDataAdapter dataAdapter dataAdapter = create System.Data.CData.AzureDataCatalog.AzureDataCatalogDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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