example 2: users have bean changed after '2013-05-12 00:00:00.0'. must return: 
 id  name    modify_date            modify_type  55  usera   2013-05-07 15:47:53.0  1 88  userb   2013-05-07 16:00:57.0  1 55  usera   2013-05-08 11:44:10.0  2 88  userb   2013-05-08 15:47:09.0  2  88  userb   2013-05-08 16:01:41.0  1     55  usera   2013-05-09 15:11:53.0  0 55  usera   2013-05-09 16:00:57.0  0 55  usera   2013-05-10 09:14:10.0  1 88  userb   2013-05-10 16:01:41.0  2 55  usera   2013-05-10 18:23:03.0  2 55  usera   2013-05-11 09:14:10.0  2 88  userb   2013-05-11 16:01:41.0  1   55  usera   2013-05-13 11:34:07.0  1 55  usera   2013-05-13 15:53:04.0  2 **55    usera   2013-05-13 16:13:04.0  1**  return

i found don't know put condition date after x:

select u1.* user_log u1 left join user_log u2 on (u1.id = u2.id , u1.modify_date < u2.modify_date ) u2.modify_date null;

can please me this?

well, these purposes analytical functions invented.

here are:

select distinct   id,   name,    last_value(modify_date) on (partition id order modify_date rows between unbounded preceding , unbounded following) modify_date   user_log   modify_date > :date
