title: A good reference for Oracle PL/SQL
body: <p>What are the best references for Oracle PL/SQL? I have an excellent knowlege of SQL-92 and of MS-SQL extensions, but now I'm working with Oracle and I'm struggling to find good references for the PL/SQL language.</p>
  
  <p>I am looking for references for the following:</p>
  
  <ul>
  <li>Variable </li>
  <li>Loops </li>
  <li>Cursor </li>
  <li>Packages</li>
  <li>Trigger </li>
  <li>Stored Procedures</li>
  <li>Temporary Tables</li>
  </ul>
  
  <p>Thanks so much.</p>
