   You can never hide anything from a system admin.   
      
   The point with TDE is to protect data at rest. If someone manages to get   
   hold of the database files or database backup without having the encryption   
   key, he is not able to access the data.   
      
   But if the user is able to connect to the server and has permissions enough,   
   he can also see tables and procedures. And someone on the server needs to   
   have that protection.   
      
   It also worth pointing out that TDE is only available in Enterprise Edition.   
      
   The proper way to protect intellectual property is through license   
   agreements.   
      
   The only possible solution from a technical point of view is to host the   
   application yourself - which of course is an immense investment.
