title: Specify Windows Username in SQL Script Without Knowing Machine Host Name
body: <p>I'd like to reference a user account on a Windows machine, without knowing the host name of the machine.</p>
  
  <p>Specifically, I am assigning permissions on a SQL server database, in a sql script, that will give permissions to a local user account on that machine.</p>
  
  <p>For example:
  CREATE USER [UserA] FOR LOGIN [MACHINENAME\UserA] WITH DEFAULT_SCHEMA=[dbo]</p>
  
  <p>This script is invoked as part of an installation process, so I don't know the 'MACHINENAME' ahead of time.</p>
  
  <p>Is there a special token meaning 'the local machine' that I can use? Something like:
  '.\UserA', or 'localhost\UserA'?</p>
  
  <p>Thanks!!</p>
