title: CodeIgniter update() defaults to insert()
body: <p>Is this possible / true?</p>
  
  <p>For instance, if I want to update a row with the id of 1, but no row exists, will this function (update function) automatically <strong><em>insert</em></strong> a new row with the given data? Is there a parameter to enable this?</p>
  
  <p>If not, what would be the best way to handle this (if possible) without using a separate function to evaluate the table and return bool if the row exists. (Then UPDATEing or INSERTing from there)</p>
  
  <p>Not much of an issue.. Just looking for clarification and wondering if anyone knows about this.</p>
