title: What is not supported in SQL Server 2016 over 2008 R2
body: <p>I want to upgrade SQL Server from 2008 R2 to 2016. Is there a query on SQL Server 2008 R2 that is no longer supported on SQL Server 2016?</p>
  
  <p>For example, I found that the <code>RAISERROR</code> function in the <code>RAISERROR 50001 'xxx'</code> format cannot be used anymore and must use the format <code>RAISERROR ('xxx', 16.1)</code>.</p>
