hi,
please see this code

select aiah_number.aiah_number_id, aiah_number.aiah_number, 
lock.lock_status, rank.rank_value, approve.approve_status, lock.view 
from aiah_number inner join lock on aiah_number.locked = lock.lock_id 
inner join rank on aiah_number.rank = rank.rank_id inner join approve on 
aiah_number.approve = approve.approve_id order by rank_value desc limit 
1 offset 0;

and this code

select aiah_number.aiah_number_id, aiah_number.aiah_number, 
lock.lock_status, rank.rank_value, approve.approve_status, lock.view 
from aiah_number inner join lock on aiah_number.locked = lock.lock_id 
inner join rank on aiah_number.rank = rank.rank_id inner join approve on 
aiah_number.approve = approve.approve_id order by rank_value desc limit 
1 offset 1;

one record per page i'm facing a problem even if i'm running the script 
through phppgadmin it's only display the first record in the page only 
no more no less in the php code it display record 1 and records byound 
180 and so on
