Connect to Splunk Data from PowerBuilder via ADO.NET

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

   user=MyUserName;password=MyPassword;URL=MyURL;InitiateOAuth=GETANDREFRESH;

   To authenticate requests, set the , , and properties to valid Splunk credentials. The port on which the requests are made to Splunk is port 8089.

   The data provider uses plain-text authentication by default, since the data provider attempts to negotiate TLS/SSL with the server.

   If you need to manually configure TLS/SSL, see Getting Started -> Advanced Settings in the data provider 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 Splunk 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.Splunk.SplunkConnection conn 
conn = create System.Data.CData.Splunk.SplunkConnection(connectionString)

System.Data.CData.Splunk.SplunkCommand comm 
comm = create System.Data.CData.Splunk.SplunkCommand(command, conn)

System.Data.DataTable table
table = create System.Data.DataTable

System.Data.CData.Splunk.SplunkDataAdapter dataAdapter
dataAdapter = create System.Data.CData.Splunk.SplunkDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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