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

Using the OktaDataAdapter

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 OktaDataAdapter is slower than the OktaDataReader because the Fill method needs to retrieve all data from the data source before returning.

The following example selects the Id and ProfileFirstName columns of the Users table:

C#

string connectionString = "Domain=dev-44876464.okta.com;OAuthClientId=myId;OAuthClientSecret=mySecret;InitiateOAuth=GETANDREFRESH;";

using (OktaConnection connection = new OktaConnection(connectionString)) {
  OktaDataAdapter dataAdapter = new OktaDataAdapter(
  "SELECT Id, ProfileFirstName FROM Users", connection);

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

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

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

VB.NET

Dim connectionString As String = "Domain=dev-44876464.okta.com;OAuthClientId=myId;OAuthClientSecret=mySecret;InitiateOAuth=GETANDREFRESH;"

Using connection As New OktaConnection(connectionString)
  Dim dataAdapter As New OktaDataAdapter("SELECT Id, ProfileFirstName FROM Users", connection)

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

  Console.WriteLine("Contents of Users.")

  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("Id"), row("ProfileFirstName"))
  Next
