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):

SELECT Id, AddressLines INTO [csv://Constituents.txt] FROM [Constituents] WHERE Type = 'Home'

You can specify other formats in the file URI. The possible delimiters are tab, semicolon, and comma with the default being a comma. The following example exports tab-separated values:

SELECT Id, AddressLines INTO [csv://Constituents.txt;delimiter=tab] FROM [Constituents] WHERE Type = 'Home'

C#

String connectionString = "SubscriptionKey=MySubscriptionKey;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;";

using (RaiserEdgeNXTConnection connection = new RaiserEdgeNXTConnection(connectionString)) {
  RaiserEdgeNXTCommand cmd = new RaiserEdgeNXTCommand("SELECT Id, AddressLines INTO [csv://Constituents.txt] FROM [Constituents] WHERE Type = 'Home' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "SubscriptionKey=MySubscriptionKey;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;" 

Using connection As New RaiserEdgeNXTConnection(connectionString)
  Dim cmd As New RaiserEdgeNXTCommand("SELECT Id, AddressLines INTO [csv://Constituents.txt] FROM [Constituents] WHERE Type = 'Home'", 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 = "SubscriptionKey=MySubscriptionKey;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;";

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

VB.NET

Dim connectionString As [String] = "SubscriptionKey=MySubscriptionKey;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;" 

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