title: Oracle syntax Vs teradata Syntax
body: <p>Let's say I have 2 columns Start date and end date both are timestamp.</p>
  
  <p>I want to subtract both (Start date - end date ) as date diff</p>
  
  <p>But it's throwing me error. What should be the correct syntax.</p>
  
  <p>Note:- I am doing this in teradata</p>
