title: FROM keyword not found where expected (Oracle SQL)
body: <p>I am currently working on some select queries and am getting the error <code>FROM keyword not found where expected</code> in my last two queries, and I can;t for the life of me figure out what the problem is...</p>
  
  <p><strong>Here are my queries</strong></p>
  
  <pre><code>SELECT Title, PubID AS 'Publisher ID', PubDate AS 'Publish Date' 
  FROM Books WHERE PubID = 4 OR PubDate &gt; '01-Jan-01' 
  ORDER BY PubID ASC;
  
  SELECT Title, (((Retail-Cost)/Cost) * 100) AS 'Markup %' 
  FROM Books;
  </code></pre>
  
  <p>I am not sure if my math is correct in this one <code>(retail - cost / cost * 100 is the goal)</code>.</p>
  
  <p>I have been trying for probably 45 minutes on the first query before giving up and doing the last one, to only get the same error on that one.</p>
