title: "data manipulation operation not legal on this view" happening in a user table
body: <p>This error is happening when I'm trying to insert values on a table belong to the user which I'm using:</p>
  
  <pre><code>SQL Error: ORA-01732: data manipulation operation not legal on this view
  *Cause:    
  *Action:
  </code></pre>
  
  <p>In all the places the people say that it occurs when trying to insert/update/delete on a view, but it is certainly a table, and the user has the privileges needed.</p>
  
  <p>So, there is any other cause for this happening beyond trying to do ilegal operation with a view?</p>
