Example #1 cubrid_unbuffered_query example

<?php
    $link = cubrid_connect("localhost", 30000, "demodb", "dba", "");
    if (!$link)
    {
        die('Could not connect.');
    }
    $query = "select * from code";
    $result = cubrid_unbuffered_query($query, $link);

    while ($row = cubrid_fetch($result))

Notes

Note:
The benefits of cubrid_unbuffered_query come at a cost: you cannot use cubrid_num_rows and cubrid_data_seek on a result set returned from cubrid_unbuffered_query.
