title: Mimic a call to Oracle package function in HSQLDB
body: <p>I am looking for a way to mimic a call to Oracle package function in my embedded database. I use the following code to call a function:</p>
  
  <pre><code>conn.prepareCall("begin ? := pkg.my_func(?); end;");
  </code></pre>
  
  <p>The problem is that I couldn't find a way to create a package in HSQLDB.</p>
