修改 WordPress 文章 id 在正常使用中应用场景并不多，今天简单讲一下通过 sql 设置 wordpress 文章 id 替换的方法。进入 mysql 命令或者 phpmyadmin 的 SQL，执行如下命令即可：如将文章 ID 为 3368 的文章修改为 189

1. update wp_posts set id = 3368 where id = 189;<br>

2. update wp_term_relationshi<a href="/fw/photo.HTML" target="_blank">ps</a> set object_id = 3368 where object_id = 189;<br>

3. update wp_postmeta set post_id = 3368 where post_id = 189;<br>

4. update wp_comments set comment_post_ID = 3368 where comment_post_ID = 189;

如果是主题使用的是虚拟主机，可以使用以下代码：

1. UPDATE `wp_posts` SET `ID` = '189',`guid` = <a href="http://www.22vd.com">www.22vd.com</a> 189' WHERE `wp_posts`.`ID` =3368;<br>

2. UPDATE `wp_term_relationships` SET `object_id` = '189' WHERE `wp_term_relationships`.`object_id` =3368;<br>

3. UPDATE `wp_postmeta` SET `post_id` = '189' WHERE `wp_postmeta`.`post_id` =3368;<br>

4. UPDATE `wp_postmeta` SET `post_id` = '189' WHERE `wp_postmeta`.`post_id` = 3368;<br>

5. UPDATE `wp_comments` SET `comment_post_ID` = '189' WHERE `wp_comments`.`comment_post_ID` = 3368;
