Question

I run a query and get a result set. I need to get the nth record from this result set. Any ideas how I can do this?

I cannot select the nth record from the database directly coz I need to filter it and don’t know how many records there are in the result set. So I cannot be certain which number to pass to the mysql_result method i.e.

1. Based on certain conditions, get a few rows from a table
2. From these rows, select the nth row (the number n is not fixed. It depends on the number of records returned)

The basic idea is to get all results based on a set condition and get a random result from these.

Any ideas? Thanks.

Your question seems unclear. However here’s a guess:

You want to select the record in the middle:

$count = mysql_num_rows($result);
$middle_name = mysql_result($result, intval($count/2), 'name');

Besides that, you can also do that if you have really less records:

$rs = array();
while ($row = mysql_fetch_assoc($result)){
     $rs[] = $row;
}

and then you can use $rs[N-1] to reach Nth record.

Read mysql_data_seek from PHP Manual if you will fetch just one record.
