SELECT INTO ステートメントを使って、書式付きデータをファイルにエクスポートできます。

SQL クエリを使ったデータのエクスポート

次のクエリは、comma-separated values（CSV）ファイルフォーマットにデータをエクスポートします。

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;";

using (XeroConnection connection = new XeroConnection(connectionString)) {
  XeroCommand cmd = new XeroCommand("SELECT Discount, Name INTO [csv://Contacts.txt] FROM [Contacts] WHERE ContactStatus = 'ACTIVE' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;" 

Using connection As New XeroConnection(connectionString)
  Dim cmd As New XeroCommand("SELECT Discount, Name INTO [csv://Contacts.txt] FROM [Contacts] WHERE ContactStatus = 'ACTIVE'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
