title: Function in SQL Server 2008 similar to GREATEST in mysql?
body: <p>I want to find the maximum value of multiple columns.</p>
  
  <p>MySQL supports the <a href="http://dev.mysql.com/doc/refman/5.6/en/comparison-operators.html#function_greatest" rel="noreferrer"><code>GREATEST</code></a> function but SQL Server doesn't.</p>
  
  <p>Is there any function similar to this in SQL Server 2008?</p>
