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 = "AccountEndpoint=myAccountEndpoint;AccountKey=myAccountKey;";

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

VB.NET

Dim connectionString As [String] = "AccountEndpoint=myAccountEndpoint;AccountKey=myAccountKey;" 

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