Question

How can i find second largest number in case i dont find the number i’ve searched?
for example
i am searching 3000 and on my db the largest number i’ve got is 2900 how can i find the second largest?

PHP Code:

$query = $select->from('numbers', array(
    'id'))
    ->where('number=?',$big_number);

Try with <= instead of =

$query = $select->from('numbers', array(
    'id'))
    ->where('number<=?',$big_number)
    ->order('number DESC')
    ->limit(0, 1);

Order the resultset descending by the number, then limit the resultset to 1 row……
