You can use the SELECT INTO statement to export formatted data to a file.

Data Export with an SQL Query

The following query exports data into a file formatted in comma-separated values (CSV):

C#

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

using (JSONConnection connection = new JSONConnection(connectionString)) {
  JSONCommand cmd = new JSONCommand("SELECT personal.name.first, personal.name.last INTO [csv://NorthwindOData.txt] FROM [NorthwindOData] WHERE personal.name.last = 'ana.trujilo@northwind.org' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

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

Using connection As New JSONConnection(connectionString)
  Dim cmd As New JSONCommand("SELECT personal.name.first, personal.name.last INTO [csv://NorthwindOData.txt] FROM [NorthwindOData] WHERE personal.name.last = 'ana.trujilo@northwind.org'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using

You can specify other file formats in the URI. The following example exports tab-separated values:

C#

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

using (JSONConnection connection = new JSONConnection(connectionString)) {
  JSONCommand cmd = new JSONCommand("SELECT * INTO [NorthwindOData] IN [csv://filename=c:/NorthwindOData.csv;delimiter=tab] FROM [NorthwindOData] WHERE personal.name.last = 'ana.trujilo@northwind.org'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

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

Using connection As New JSONConnection(connectionString)
  Dim cmd As New JSONCommand("SELECT * INTO [NorthwindOData] IN [csv://filename=c:/NorthwindOData.csv;delimiter=tab] FROM [NorthwindOData] WHERE personal.name.last = 'ana.trujilo@northwind.org'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
