  Eswar, you code is close:

  UPDATE t SET disabled = 1

  FROM tasks AS t, milestones AS m

  WHERE t.milestoneid = m.milestoneid

  AND m.projectid=15

  Using proper join syntax this is

  UPDATE t SET disabled = 1

  FROM tasks AS t

  INNER JOIN milestones AS m

  ON t.milestoneid = m.milestoneid AND m.projectid=15

  Cheers
