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 Email, Username INTO [csv://NorthwindOData.txt] FROM [NorthwindOData] WHERE Email = '[email protected]'

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 Email, Username INTO [csv://NorthwindOData.txt;delimiter=tab] FROM [NorthwindOData] WHERE Email = '[email protected]'

C#

String connectionString = "DataModel=Relational;URI=C:\people.xml";

using (XMLConnection connection = new XMLConnection(connectionString)) {
  XMLCommand cmd = new XMLCommand("SELECT Email, Username INTO [csv://NorthwindOData.txt] FROM [NorthwindOData] WHERE Email = '[email protected]' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "DataModel=Relational;URI=C:\people.xml" 

Using connection As New XMLConnection(connectionString)
  Dim cmd As New XMLCommand("SELECT Email, Username INTO [csv://NorthwindOData.txt] FROM [NorthwindOData] WHERE Email = '[email protected]'", 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 = "DataModel=Relational;URI=C:\people.xml";

using (XMLConnection connection = new XMLConnection(connectionString)) {
  XMLCommand cmd = new XMLCommand("SELECT * INTO [NorthwindOData] IN [csv://filename=c:/NorthwindOData.csv;delimiter=tab] FROM [NorthwindOData] WHERE Email = '[email protected]'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "DataModel=Relational;URI=C:\people.xml" 

Using connection As New XMLConnection(connectionString)
  Dim cmd As New XMLCommand("SELECT * INTO [NorthwindOData] IN [csv://filename=c:/NorthwindOData.csv;delimiter=tab] FROM [NorthwindOData] WHERE Email = '[email protected]'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
