Example #1 cubrid_field_flags() example


<?php
    $link = cubrid_connect("localhost", 30000, "demodb2", "dba", "");
    if (!$link)
    {
        die('Could not connect.');
    }
    $query = 'SELECT id, name, address, salary FROM employees';
    $result = cubrid_execute($link, $query);
    if ($result) 
    {
        $flags = cubrid_field_flags($result, 0);
        print_r(explode(' ', $flags));
        cubrid_close_request($result);
