UPDATE wp_posts SET post_content = replace(post_content, '旧域名','新域名'); UPDATE wp_posts SET guid = replace(post_content, '旧域名','新域名'); UPDATE wp_comments SET comment_content = replace(comment_content, '旧域名','新域名'); UPDATE wp_comments SET comment_author_url = replace(comment_author_url, '旧域名','新域名'); UPDATE wp_options SET option_value = replace(option_value , '旧域名','新域名');
