title: Oracle Age calculation from Date of birth and Today
body: <p>I want to calculate the current Age from Date of Birth in my Oracle function.</p>
  
  <p>What I am using is <code>(Today-Dob)/30/12</code>, but this is not accurate as some months have 31 days. </p>
  
  <p>I need to get the correct age with the maximum precision. How can I do that? </p>
