title: Inserting a value on a frozen set in cassandra 3
body: <p>I am currently working on a Cassandra 3 database in which one of its tables has a column that is defined like this:</p>
  
  <pre><code>column_name map&lt;int, frozen &lt;set&lt;int&gt;&gt;&gt;
  </code></pre>
  
  <p>When I have to change the value of a complete set given a map key <strong>x</strong> I just have to do this:</p>
  
  <pre><code>UPDATE keyspace.table SET column_name[x] = {1,2,3,4,5} WHERE ...
  </code></pre>
  
  <p>The thing is that I need to insert a value on a set given a key. I tried with this:</p>
  
  <pre><code>UPDATE keyspace.table SET column_name[x] = column_name[x] + {1} WHERE ...
  </code></pre>
  
  <p>But it returns:</p>
  
  <blockquote>
    <p>SyntaxException: line 1:41 no viable alternative at input '[' (... SET column_name[x] = [column_name][...)</p>
  </blockquote>
  
  <p>What am I doing wrong? Does anyone know how to insert data the way I need?</p>
