title: Linq2DB and query for dynamic
body: <p>I'm trying to perform a query without having created a model that maps it.
  Consider this snippet</p>
  
  <pre><code>public IDictionary&lt;string, int&gt; GetParentelaMapping()
      {
          using (var conn = dataContextFactory.Create())
          {
              var result = conn.Query&lt;dynamic&gt;("SELECT ID_GRADO_PARENTELA,GRADO_PARENTELA FROM GRADO_PARENTELA")
                  .ToDictionary(
                      row =&gt; (string)row.GRADO_PARENTELA,
                      row =&gt; (int)row.ID_GRADO_PARENTELA, StringComparer.OrdinalIgnoreCase);
  
              return result;
          }
      }
  </code></pre>
  
  <p>It gaves me an exception that 
  Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: ''int' does not contain a definition for 'GRADO_PARENTELA''</p>
  
  <p>How can I handle such a case?
  Thanks</p>
