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 = "Server=127.0.0.1;";

using (SparkSQLConnection connection = new SparkSQLConnection(connectionString)) {
  SparkSQLCommand cmd = new SparkSQLCommand("SELECT City, CompanyName INTO [csv://Customers.txt] FROM [Customers] WHERE Country = 'US' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "Server=127.0.0.1;" 

Using connection As New SparkSQLConnection(connectionString)
  Dim cmd As New SparkSQLCommand("SELECT City, CompanyName INTO [csv://Customers.txt] FROM [Customers] WHERE Country = 'US'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
