清理wordpress的数据库

清理数据表为: wp_options, wp_posts, wp_postmeta. 我使用一款插件来完成clean-options,网上也经常采取删除这个数据库表的方法来处理.不过会丢失一些设置. 我也是使用的一款插件处理的 WP Cleaner . 下面在给出几条语句让你的wp_postmeta干净到非常.

DELETE FROM wp_postmeta WHERE meta_key = '_edit_lock';
DELETE FROM wp_postmeta WHERE meta_key = '_edit_last';

这是之前给出的两条语句测试安全删除无危险.

DELETE FROM wp_postmeta WHERE meta_key = '_wp_old_slug';
DELETE FROM wp_postmeta WHERE meta_key = '_revision-control';
DELETE FROM wp_postmeta WHERE meta_value = '{{unknown}}';
