title: Apache Drill - creating own table by CTAS
body: <p>The CTAS commans is: <code>CREATE TABLE new_table_name AS &lt;query&gt;;</code><br>
  However, before creating table I have to create schema.  I can't do it, moreover I can't use existing schema because for each installed yet schema I get error:<br>
  <code>schema cp is immutable</code>. Hence solution is create new schema.  The problem is that I can't find any example of this command.  </p>
