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 Name, CloseDate INTO [csv://Dataset_Opportunity.txt] FROM [Dataset_Opportunity] WHERE StageName = 'Closed Won'

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 Name, CloseDate INTO [csv://Dataset_Opportunity.txt;delimiter=tab] FROM [Dataset_Opportunity] WHERE StageName = 'Closed Won'

C#

String connectionString = "OAuthClientId=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber";

using (TableauCRMConnection connection = new TableauCRMConnection(connectionString)) {
  TableauCRMCommand cmd = new TableauCRMCommand("SELECT Name, CloseDate INTO [csv://Dataset_Opportunity.txt] FROM [Dataset_Opportunity] WHERE StageName = 'Closed Won' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "OAuthClientId=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber" 

Using connection As New TableauCRMConnection(connectionString)
  Dim cmd As New TableauCRMCommand("SELECT Name, CloseDate INTO [csv://Dataset_Opportunity.txt] FROM [Dataset_Opportunity] WHERE StageName = 'Closed Won'", 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 = "OAuthClientId=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber";

using (TableauCRMConnection connection = new TableauCRMConnection(connectionString)) {
  TableauCRMCommand cmd = new TableauCRMCommand("SELECT * INTO [Dataset_Opportunity] IN [csv://filename=c:/Dataset_Opportunity.csv;delimiter=tab] FROM [Dataset_Opportunity] WHERE StageName = 'Closed Won'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "OAuthClientId=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber" 

Using connection As New TableauCRMConnection(connectionString)
  Dim cmd As New TableauCRMCommand("SELECT * INTO [Dataset_Opportunity] IN [csv://filename=c:/Dataset_Opportunity.csv;delimiter=tab] FROM [Dataset_Opportunity] WHERE StageName = 'Closed Won'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
