title: SQL Query to list all empty colums in one Table
body: <p>I'm struggling to build a query to list all empty columns in one table.
  Is there a simple function to do that, something like: </p>
  
  <pre><code>SELECT COLUMN_NAME 
  FROM INFORMATION_SCHEMA.COLUMNS 
  WHERE TABLE_NAME = 'MyTable' AND COLUMN IS NOT EMPTY
  </code></pre>
  
  <p>Thanks for your help</p>
