title: How to check if a sequence exists in my schema?
body: <p>Is there a way to retrieve all the sequences defined in an existing oracle-sql db schema?</p>
  
  <p>Ideally I would like to use something like this:</p>
  
  <pre><code>SELECT * FROM all_sequences WHERE owner = 'me';
  </code></pre>
  
  <p>which apparently doesn't work.</p>
