title: kdb/q, reserved word as column name
body: <p>I have a kdb table with column name <code>type</code> and want to select data by a giving type.  It's like:</p>
  
  <pre><code>select from table where type=giving_type
  </code></pre>
  
  <p>it issues an error of : <code>'type</code>, because type is a reserved word in q.</p>
  
  <p>Then how to do this?</p>
