Hey,
Thanks for replying.

Theres something wrong coz its not working as expected...
I followed instructions and created a table like this:


CREATE TABLE test_last_visitors (
  profile_id int(10) default NULL,
  user_id int(10) default NULL,
  ttimestamp timestamp(14) NOT NULL) TYPE=MyISAM;

then I ran this 5 times: (logic being: test with 5, if it works go with 10
or more) :-)
insert into `test_last_visitors` values(1,1,now());

then from my php script (test_last_visitors.php) I ran this test SQL:
$SQL = "UPDATE test_last_visitors SET profile_id=".$profile_id.",
user_id=user_id+1,
ttimestamp=now() WHERE profile_id=1 ORDER BY ttimestamp ASC LIMIT 1";


The first 5 times it works perfectly, then after that it updates only the
latest record over and over again :-(
I tried playing with the ASC and DESC, MIN and MAX....no joy.

Any idea whats wrong?

Thanks,
Ryan
