title: hash a SQL row?
body: <p>Is there a way to md5sum a row in a SQL table to check whether any column has been modified?</p>
  
  <p>I would like to check whether any particular column has been changed versus an old copy of the data which i hold in a text file (which I will md5sum in C#).</p>
  
  <p>EDIT: Just md5sum-ing each row</p>
