title: SQL server: can't save/change table design
body: <p>I'm trying to make changes to an existing table and am getting this error when i try to save : </p>
  
  <blockquote>
    <p>Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created.</p>
  </blockquote>
  
  <p>I only have one data entry in the database - would deleting this solve the problem or do i have to re-create the tables as the error suggests? (This is on SQL-Server 2008 R2)</p>
