title: SQLLDR -- selective loading from pipe delimited txt
body: <p>I am looking for a way to do selective loading using SQLLDR. 
  The source file is in "pipe delimited" format.</p>
  
  <p>I know there is a way for this if the source is in a predefined position. It is explained <a href="http://www.orafaq.com/wiki/SQL%2aLoader_FAQ#Can_one_selectively_load_only_the_records_that_one_needs.3F" rel="nofollow">here</a>, by using WHEN &amp; POSITION keywords.</p>
  
  <p>What could I do if the source file is "pipe or tab" delimited?</p>
