Question

I want to get a result from sql with unlimited rows, I don’t want to use limit in my sql statement because I need to know the total number of rows. But I just want to echo, for example row 30-60.

I use php.

http://php.net/manual/en/function.mysql-data-seek.php

mysql_data_seek() moves the internal row pointer of the MySQL result associated with the specified result identifier to point to the specified row number. The next call to a MySQL fetch function, such as mysql_fetch_assoc(), would return that row.

mysql_data_seek($res, 30);
for ($i = 0; $i < 30; ++$i) {
  $row = mysql_fetch_assoc($res);
  var_dump($row);      
}
