Compare Timestamp with a number in hours

Question

Hi,
Need help with this question.
I want compare a timestamp with a value like 24 or 36 hour.
For example:
Timestamp: '16-jul-2010 13:00:00' when the 24 hours is pass ('17-jul-2010 13:05:10') then I want to update a table.
Is it possible to to this in pl/sql or have Oracle 11G a function in it.
I appreciate some help.
Thanks.

Having article_id in both tables you could try something like (not tested as I don't have database access)
update table_1 t1
   set result = 1
where 24 * (sysdate - timestamp_placed) > (select time
                                              from table_2
                                             where article_id = t1.article_id
                                           )Regards

sorry (working doing it from home and someone posted a not completed template)
Try to do it with a single update or else ... - you'll hear from damorgan ;)
update gkr_droogkamer1 dgr
   set result = 1
where result = 0
   and 24 * (sysdate - timestamp_placed) > (select dry_time
                                              from gkr_artikel
                                             where article_id = dgr.article_id
                                           )You'd better come up with a data sample and someone will provide a tested solution asap. Something like:
create table gkr_droogkamer1
select 1 article_id,sysdate - 50 / 24 timestamp_placed,1 result from dual union all
select 2 article_id,sysdate - 40 / 24 timestamp_placed,0 result from dual union all
select 3 article_id,sysdate - 30 / 24 timestamp_placed,0 result from dual union all
select 4 article_id,sysdate - 20 / 24 timestamp_placed,0 result from dual union all
select 5 article_id,sysdate - 10 / 24 timestamp_placed,0 result from dual;
create table gkr_artikel
select 1 article_id,36 dry_time from dual union all
select 2 article_id,36 dry_time from dual union all
select 3 article_id,24 dry_time from dual union all
select 4 article_id,24 dry_time from dual union all
select 5 article_id,24 dry_time from dual;Regards
