title: Query IN Clause with parameter
body: <p>Here is my query,</p>
  
  <pre><code>&lt;Request method="GET"&gt;
     &lt;Query&gt;
       select user_id from user
       where user_type in ($userTypes)
     &lt;/Query&gt;
  &lt;/Request&gt;
  </code></pre>
  
  <p>How do I sent multiple values for this parameter $userType in metamug resource file. I'm using a GET request. And my database is postgres.</p>
  
  <p>$userTypes is list of ids. I can pass it as comma separated string "1501,1502,1503" in the request.</p>
  
  <p>Thanks.</p>
