title: Hibernate. Add default column value after column creation
body: <p>Is there a way to set a default value for existing entries after the column has been created using Hibernate?</p>
  
  <p>Found that the operation could be done manually by:</p>
  
  <pre><code>ALTER TABLE Employee 
  ADD DEFAULT('SANDNES') FOR CityBorn
  </code></pre>
  
  <p>but is there a way to do something using hibernate?</p>
