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

Using the FacebookAdsDataReader

The FacebookAdsDataReader retrieves data faster than the FacebookAdsDataAdapter because it can retrieve data in pages. As you read data from the FacebookAdsDataReader, 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 AdAccounts table:

C#

string connectionString = "InitiateOAuth=GETANDREFRESH;";

using (FacebookAdsConnection connection = new FacebookAdsConnection(connectionString)) {
  FacebookAdsCommand cmd = new FacebookAdsCommand("SELECT * FROM AdAccounts", connection);
  
  FacebookAdsDataReader rdr = cmd.ExecuteReader();

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

VB.NET

Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;"

Using connection As New FacebookAdsConnection(connectionString)
  Dim cmd As New FacebookAdsCommand("SELECT * FROM AdAccounts", connection)

  Dim rdr As FacebookAdsDataReader = cmd.ExecuteReader()

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