title: Finding Null values in multiple columns in SQL
body: <p>What are the best and the most efficient way of finding null values in multiple columns.  For example:</p>
  
  <pre><code>Name     Location    Age      Address
  Mike       CLT        19       Null
  Null        NY        28        Null
  </code></pre>
  
  <p>and so on...
  I just need to find out if there is any NULL value in any of these columns.   </p>
