교재 게시판 응용관련해서 문의드립니다.
게시판에서 특정글 하나만 맨위로 고정을 시키고 싶습니다.
sql과 view단을 어떻게 조정하면 가능할까요?

$sql = "SELECT * FROM ".$table.$sword." ORDER BY board_id DESC".$limit_query;
			$query = $this->db->query($sql);

Board_m.php

 <?php
    foreach ($list as $lt)
    {
    ?>
        <tr>
            <th scope="row">
                <?php  echo $lt->board_id;?>
            </th>
            <td> <a rel="external" href="/<?php echo $this->uri->segment(1);?>/view/<?php echo $this->uri->segment(3);?>/board_id/<?php echo $lt->board_id;?>/page/<?php echo $page;?>"><?php echo $lt->subject;?></a></td>
            <td><?php echo $lt->user_name;?></td>
            <td><?php echo $lt->hits;?></td>
            <td><time datetime="<?php echo mdate("%Y-%M-%j", human_to_unix($lt->reg_date));?>">
            <?php echo mdate("%Y.%m.%j", human_to_unix($lt->reg_date));?></time></td>
        </tr>
    <?php
    }
    ?>
