如果您愿意重新导入整个数据库,最好使用 MySQL 转储方法。对于不想这样做的任何人 - WordPress 核心安装实际上只包含 11 个表,其中很少有内容列,因此按列替换同样容易。假设您没有大量引用链接或字符串的插件表,这将是您的 SQL:
UPDATE wp_commentmeta SET meta_value = REPLACE(meta_value,'xcurrentx','xreplacementx');
UPDATE wp_comments SET comment_content = REPLACE(comment_content,'xcurrentx','xreplacementx');
UPDATE wp_links SET link_description = REPLACE(link_description,'xcurrentx','xreplacementx');
UPDATE wp_options SET option_value = REPLACE(option_value,'xcurrentx','xreplacementx');
UPDATE wp_postmeta SET meta_value = REPLACE(meta_value,'xcurrentx','xreplacementx');
UPDATE wp_posts SET post_content = REPLACE(post_content,'xcurrentx','xreplacementx');
UPDATE wp_posts SET post_title = REPLACE(post_title,'xcurrentx','xreplacementx');
UPDATE wp_posts SET post_excerpt = REPLACE(post_excerpt,'xcurrentx','xreplacementx');
UPDATE wp_term_taxonomy SET description = REPLACE(description,'xcurrentx','xreplacementx');
UPDATE wp_usermeta SET meta_value = REPLACE(meta_value,'xcurrentx','xreplacementx');
