尝试此操作,它将删除现有的wp\\U commentmeta表,然后创建“wp\\U commentmeta”表:
DROP TABLE IF EXISTS `wp_commentmeta`;
CREATE TABLE `wp_commentmeta` (
`meta_id` bigint(20) UNSIGNED NOT NULL,
`comment_id` bigint(20) UNSIGNED NOT NULL DEFAULT \'0\',
`meta_key` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`meta_value` longtext COLLATE utf8mb4_unicode_ci
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
