title: SQL Server db_owner
body: <p>in my SQL2008 I have a user which is in the "db_datareader", "db_datawriter" and "db_ddladmin" DB roles, however when he tries to modify a table with SSMS he receives a message saying:</p>
  
  <p><em>You are not logged in as the database owner or system administrator. You might not be able to save changes to tables that you do not own.</em></p>
  
  <p>Of course, I would like to avoid such message, but until now I did find the way...
  Therefore, I try to modify the user by adding him to the "db_owner" role, and of course I do not have the message above.</p>
  
  <p>My question is:</p>
  
  <ul>
  <li>Is it possible to keep the user in the "db_owner" role, but deny some actions like alter user or ? I try "alter any user" securable on DB level, but it does not work...</li>
  </ul>
  
  <p>THANKS!</p>
