I just came across this by accident; PyDO questions are better asked
on the skunkweb mailing list.

But to answer it quickly -- the delete() method deletes a particular
instance (one row).  If you want delete a range of rows with a single
SQL statement, the best way is simply to use SQL, accessing the
underlying db connection:

  c=Sessions.getDBI().conn.cursor()
  c.execute("DELETE FROM SESSIONS WHERE acc_time < '333333'")
  # this is equivalent to Sessions.getDBI().conn.commit()
  Sessions.commit()

Hope that helps,
