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 = "ApiKey=MyApiKey;ShopId=MyShopId;";

using (auPAYMarketConnection connection = new auPAYMarketConnection(connectionString)) {
  auPAYMarketCommand cmd = new auPAYMarketCommand("SELECT ItemCode, LotNumber INTO [csv://Items.txt] FROM [Items] WHERE LotNumber = '12345' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "ApiKey=MyApiKey;ShopId=MyShopId;" 

Using connection As New auPAYMarketConnection(connectionString)
  Dim cmd As New auPAYMarketCommand("SELECT ItemCode, LotNumber INTO [csv://Items.txt] FROM [Items] WHERE LotNumber = '12345'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
