范例

Example #1 cubrid_field_seek() 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) 
    {
        cubrid_field_seek($result,2);
        $meta = cubrid_fetch_field($result);
        if (!$meta) 
        {
            echo "No information available<br />\n";
        }
        echo "<pre>
        max_length:        $meta->max_length
        multiple_key:        $meta->multiple_key
        name:            $meta->name
        not_null:        $meta->not_null
        numeric:        $meta->numeric
        table:            $meta->table
        type:            $meta->type
        default:        $meta->def
        unique_key:        $meta->unique_key
        </pre>";


        cubrid_close_request($result); 
    }
?>
