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 sys_id, priority INTO [csv://incident.txt] FROM [incident] WHERE category = 'request'

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 sys_id, priority INTO [csv://incident.txt;delimiter=tab] FROM [incident] WHERE category = 'request'

C#

String connectionString = "OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;";

using (ServiceNowConnection connection = new ServiceNowConnection(connectionString)) {
  ServiceNowCommand cmd = new ServiceNowCommand("SELECT sys_id, priority INTO [csv://incident.txt] FROM [incident] WHERE category = 'request' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;" 

Using connection As New ServiceNowConnection(connectionString)
  Dim cmd As New ServiceNowCommand("SELECT sys_id, priority INTO [csv://incident.txt] FROM [incident] WHERE category = 'request'", 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=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;";

using (ServiceNowConnection connection = new ServiceNowConnection(connectionString)) {
  ServiceNowCommand cmd = new ServiceNowCommand("SELECT * INTO [incident] IN [csv://filename=c:/incident.csv;delimiter=tab] FROM [incident] WHERE category = 'request'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;" 

Using connection As New ServiceNowConnection(connectionString)
  Dim cmd As New ServiceNowCommand("SELECT * INTO [incident] IN [csv://filename=c:/incident.csv;delimiter=tab] FROM [incident] WHERE category = 'request'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
