title: SQL Server Trigger Isolation / Scope Documentation
body: <p>I have been looking for <strong>definitive</strong> documentation regarding the isolation level ( or concurrency or scope ... I'm not sure EXACTLY what to call it) of triggers in SQL Server.</p>
  
  <p>I have found the following sources which indicate that what I believe is true (which is to say that two users, executing updates to the same table --even the same rows-- will then have independent and isolated triggers executed):</p>
  
  <ul>
  <li><p><a href="https://social.msdn.microsoft.com/Forums/sqlserver/en-US/601977fb-306c-4888-a72b-3fbab6af0cdc/effects-of-concurrent-trigger-firing-on-inserted-and-deleted-tables?forum=transactsql" rel="noreferrer">https://social.msdn.microsoft.com/Forums/sqlserver/en-US/601977fb-306c-4888-a72b-3fbab6af0cdc/effects-of-concurrent-trigger-firing-on-inserted-and-deleted-tables?forum=transactsql</a></p></li>
  <li><p><a href="https://social.msdn.microsoft.com/forums/sqlserver/en-US/b78c3e7b-6b98-48e1-ad43-3c773c79a6ff/trigger-and-inserted-table" rel="noreferrer">https://social.msdn.microsoft.com/forums/sqlserver/en-US/b78c3e7b-6b98-48e1-ad43-3c773c79a6ff/trigger-and-inserted-table</a>  </p></li>
  </ul>
  
  <p>The first question is essentially the same question I am trying to find the answer to, but the answer given doesn't provide any sources.  The second question also hits near the mark, and the answer is the same, but again, no sources are provided.</p>
  
  <p>Can someone point me to where the available documentation makes the same assertions?</p>
  
  <p>Thanks!</p>
