Connect to SAS Data Sets Data from PowerBuilder


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

This article demonstrates using the CData ADO.NET Provider for SAS Data Sets 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 SAS Data Sets 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:

    URI=C:/myfolder;

    Set the following connection properties to connect to your SAS DataSet files:

    Connecting to Local Files

    • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
    • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

    Connecting to Cloud-Hosted SAS DataSet Files

    While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

    Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of 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=name}" Header="name" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for SAS Data Sets 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.SASDataSets.SASDataSetsConnection conn conn = create System.Data.CData.SASDataSets.SASDataSetsConnection(connectionString) System.Data.CData.SASDataSets.SASDataSetsCommand comm comm = create System.Data.CData.SASDataSets.SASDataSetsCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.SASDataSets.SASDataSetsDataAdapter dataAdapter dataAdapter = create System.Data.CData.SASDataSets.SASDataSetsDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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