ADO.NET Provider for Splunk

Build 24.0.8963

Querying with the DataAdapter

The CData ADO.NET Provider for Splunk implements two ADO.NET interfaces you can use to retrieve data from Splunk: SplunkDataAdapter and SplunkDataReader objects. Whereas SplunkDataAdapter objects retrieve a single result set of all the data that matches a query, SplunkDataReader objects fetch data in subset increments as needed.

Using the SplunkDataAdapter

Use the adapter's Fill method to retrieve data from the data source. An empty DataTable instance is passed as an argument to the Fill method. When the method returns, the DataTable instance is populated with the queried data. Note that the SplunkDataAdapter is slower than the SplunkDataReader because the Fill method needs to retrieve all data from the data source before returning.

The following example selects the Name and Owner columns of the DataModels table:

C#

string connectionString = "user=MyUserName;password=MyPassword;URL=MyURL;";

using (SplunkConnection connection = new SplunkConnection(connectionString)) {
  SplunkDataAdapter dataAdapter = new SplunkDataAdapter(
  "SELECT Name, Owner FROM DataModels", connection);

  DataTable table = new DataTable();
  dataAdapter.Fill(table);

  Console.WriteLine("Contents of DataModels.");

  foreach (DataRow row in table.Rows) {
    Console.WriteLine("{0}: {1}", row["Name"], row["Owner"]);
  }
}

VB.NET

Dim connectionString As String = "user=MyUserName;password=MyPassword;URL=MyURL;"

Using connection As New SplunkConnection(connectionString)
  Dim dataAdapter As New SplunkDataAdapter("SELECT Name, Owner FROM DataModels", connection)

  Dim table As New DataTable()
  dataAdapter.Fill(table)

  Console.WriteLine("Contents of DataModels.")

  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("Name"), row("Owner"))
  Next
End Using
