Php 如何复制联接的sql表？

我试过：

INSERT INTO wp_posts_copy * (SELECT 
        *
FROM 
        wp_posts
        JOIN wp_term_relationships
                ON wp_posts.ID = wp_term_relationships.object_id
WHERE 
   wp_term_relationships.term_taxonomy_id = "48")

SQL数据库：

wp_posts => 
ID
post_author
post_date
post_date_gmt
post_content
post_title
post_excerpt
post_status
comment_status
ping_status
post_password
post_name
to_ping
pinged
post_modified
post_modified_gmt
post_content_filtered
post_parent
guid
menu_order
post_type 
post_mime_type
comment_count

wp_term_relationships =>
object_id
term_taxonomy_id
term_order

---

我想复制或导出那些wp_的职位，在这类什么已经得到了id 48。选择正在运行，但我不知道如何复制它们。那么，如何复制所选数据？它来自WP数据库。

要仅复制

WP\u帖子中的列

，您必须使用

WP\u帖子。*

而不是

*

或命名所有要使用的列

INSERT INTO wp_posts_copy
SELECT wp_posts.* FROM wp_posts
JOIN wp_term_relationships ON wp_posts.ID = wp_term_relationships.object_id
WHERE wp_term_relationships.term_taxonomy_id = "48"
