 Already imported the table and its data.
 When I execute the following:

 ALTER TABLE `wp_posts`
   ADD PRIMARY KEY (`ID`),
   ADD KEY `post_name` (`post_name`(191)),
   ADD KEY `type_status_date` (`post_type`,`post_status`,`post_date`,`ID`),
   ADD KEY `post_parent` (`post_parent`),
   ADD KEY `post_author` (`post_author`);

 I have 2013 error (in console) or 2006 (in phpmyadmin) immediately.
