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

Using the ReckonAccountsHostedDataAdapter

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

The following example selects the Id and Name columns of the Customers table:

C#

string connectionString = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;";

using (ReckonAccountsHostedConnection connection = new ReckonAccountsHostedConnection(connectionString)) {
  ReckonAccountsHostedDataAdapter dataAdapter = new ReckonAccountsHostedDataAdapter(
  "SELECT Id, Name FROM Customers", connection);

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

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

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

VB.NET

Dim connectionString As String = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;"

Using connection As New ReckonAccountsHostedConnection(connectionString)
  Dim dataAdapter As New ReckonAccountsHostedDataAdapter("SELECT Id, Name FROM Customers", connection)

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

  Console.WriteLine("Contents of Customers.")

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