title: Default column value based on the value of a identity column
body: <p>Is it possible to have a default value based on the value of the identity column?</p>
  
  <p>i.e.</p>
  
  <pre><code>alter table myTable 
       add constraint df_columnX 
       default ident_current('myTable') 
       for columnX
  </code></pre>
  
  <p>Is there another way? I want the current identity for the insert statement</p>
  
  <p>I want to avoid using a trigger och stored procedure</p>
