title: Check if any columns changed in a trigger
body: <p>I have a table that consists of 30 columns.  In another table I have a list of the columns for that table.  Some have an indicator as 0 and others with 1.</p>
  
  <p>I need to that that tables of columns were the indicator = 1 and find out if that column updated during a trigger or not. 
  I need this to be simple and with the least amount of code to implement</p>
  
  <p>Can I use columns_updated? or Updated?</p>
  
  <p>Any help would be appreciated.</p>
