title: What does a double membership operator do?
body: <p>I've no prior experience with SQL*Plus, and can't find an answer to this on Google.</p>
  
  <p>I'm wondering what the ".." operators do in SQL*Plus. I cannot find any simple explenations for it in any kind of documentation, or online.</p>
  
  <pre class="lang-sql prettyprint-override"><code>PROMPT CREATE TABLE &amp;&amp;OWNER..POINT
  </code></pre>
  
  <p>This is an example of where I see it used. Sorry if you need more context here, but I can't show the whole script because it might be sensitive information.</p>
