title: Oracle: how to "unalter" a session parameter?
body: <p>I'm doing a case-insensitive query with</p>
  
  <pre><code>alter session set NLS_COMP=LINGUISTIC;
  alter session set NLS_SORT=BINARY_CI;
  </code></pre>
  
  <p>Is there a way to easily capture the session state prior to altering it so that I can restore the session to its original state?</p>
