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

Using the MicrosoftPlannerDataReader

The MicrosoftPlannerDataReader retrieves data faster than the MicrosoftPlannerDataAdapter because it can retrieve data in pages. As you read data from the MicrosoftPlannerDataReader, it periodically requests the next page of results from the data source, if required. This causes results to be returned at a faster rate. The following example selects all the columns from the Tasks table:

C#

string connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;";

using (MicrosoftPlannerConnection connection = new MicrosoftPlannerConnection(connectionString)) {
  MicrosoftPlannerCommand cmd = new MicrosoftPlannerCommand("SELECT * FROM Tasks", connection);
  
  MicrosoftPlannerDataReader rdr = cmd.ExecuteReader();

  while (rdr.Read()) {
    Console.WriteLine(String.Format("\t{0} --> \t\t{1}", rdr["TaskId"], rdr["startDateTime"]));
  }
}

VB.NET

Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;"

Using connection As New MicrosoftPlannerConnection(connectionString)
  Dim cmd As New MicrosoftPlannerCommand("SELECT * FROM Tasks", connection)

  Dim rdr As MicrosoftPlannerDataReader = cmd.ExecuteReader()

  While rdr.Read()
    Console.WriteLine([String].Format(vbTab & "{0} --> " & vbTab & vbTab & "{1}", rdr("TaskId"), rdr("startDateTime")))
  End While
End Using
