title: SQL Server Trigger on Update (Only New Data)
body: <p>Quick question, we have a simple Trigger we need to use that Inserts into TableB for example if any 3 Columns (Lets call them c1,c2, or c3) get updated.</p>
  
  <p>However i've seen Trigger examples that do this, but I DO NOT want it to Insert if c1,c2, or c3 get updated with the same information. It can only be new info.</p>
  
  <p>I know there is the "AFTER UPDATE", but will this work if the same data is being placed in the columns (Because if so, I don't want that)</p>
