title: Finding Nth Minimum of a Varchar value in Oracle
body: <p>I have an oracle table with the columns Config_ID, Escalation_Level</p>
  
  <p>In this table the Escalation_Level is a <strong>Varchar</strong> with the values <em>'L0','L1','L2','L13','L4','L3','L5','L22','L19','L41''L98','L99</em>' in jumbled order for a Config_ID. </p>
  
  <p>How to find the Nth MIN of the Escalation_Level. As this is of Varchar type, I don't find a straight forward way.</p>
  
  <p>Please share your thoughts.</p>
  
  <p>Regards,
  Sriram </p>
