You can retrieve information on indexes, such as the primary keys, by querying the Indexes collection.

Retrieving Primary Key Information

To retrieve this schema collection, call the GetSchema method of the SplunkConnection class. You can restrict the results by table name. The following example retrieves the primary key of the Splunk table DataModels.

C#

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

using (SplunkConnection conn = new SplunkConnection(connectionString)) {
  conn.Open();
  DataTable databaseSchema = conn.GetSchema("Indexes", new string[] {"DataModels"});
  foreach (DataRow row in databaseSchema.Rows) {
    Console.WriteLine(row["INDEX_NAME"]);
    Console.WriteLine(row["PRIMARY"]);
  }
}

VB.NET

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

Using conn As New SplunkConnection(connectionString)
  conn.Open()
  Dim databaseSchema As DataTable = conn.GetSchema("Indexes",  New String() {"DataModels"})
  For Each row As DataRow In databaseSchema.Rows
    Console.WriteLine(row("INDEX_NAME"))
    Console.WriteLine(row("PRIMARY"))
  Next
End Using
