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。

SELECT FullPath, Permission INTO [csv://Resources.txt] FROM [Resources] WHERE Type = 'FILE'

ファイルURI で他のフォーマットを指定できます。利用可能な区切り文字はタブ、セミコロン、カンマです。デフォルトはカンマです。次の例は、tab-separated values（TSV）にエクスポートします。

SELECT FullPath, Permission INTO [csv://Resources.txt;delimiter=tab] FROM [Resources] WHERE Type = 'FILE'

C#

String connectionString = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;";

using (ADLSConnection connection = new ADLSConnection(connectionString)) {
  ADLSCommand cmd = new ADLSCommand("SELECT FullPath, Permission INTO [csv://Resources.txt] FROM [Resources] WHERE Type = 'FILE' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;" 

Using connection As New ADLSConnection(connectionString)
  Dim cmd As New ADLSCommand("SELECT FullPath, Permission INTO [csv://Resources.txt] FROM [Resources] WHERE Type = 'FILE'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using

URI で他のファイルフォーマットを指定できます。以下の例は、tab-separated values（TSV）にエクスポートします。

C#

String connectionString = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;";

using (ADLSConnection connection = new ADLSConnection(connectionString)) {
  ADLSCommand cmd = new ADLSCommand("SELECT * INTO [Resources] IN [csv://filename=c:/Resources.csv;delimiter=tab] FROM [Resources] WHERE Type = 'FILE'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;" 

Using connection As New ADLSConnection(connectionString)
  Dim cmd As New ADLSCommand("SELECT * INTO [Resources] IN [csv://filename=c:/Resources.csv;delimiter=tab] FROM [Resources] WHERE Type = 'FILE'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
