mysql – 使用SQL Query以CSV格式导出WordPress帖子和元信息

道歉,这是一个duplicate of entry of this post,但我发现我没有在那里得到正确的答案,不知道如何要求将其移至SO？

我需要使用CSV格式的SQL查询导出所有wordpress帖子和相关的元信息.我设法只导出帖子,但意识到元信息在另一个表中.

有人可以告诉我,我该怎么做呢？

谢谢！

编辑：我已经尝试了一些插件,其中没有一个适用于这个特定的场景.我确实需要处理查询本身.谢谢

编辑：CSV文件的最终结果应该是这样的.在一行中,这些是我最终会得到的列. (我将删除CSV中的其他列,我只是在这里提供缩短版本)

post_content | post_title | **Meta_key** | *Meta_value* | **Meta_key** | *Meta_value* | **Meta_key** | *Meta_value* | **Meta_key** | *Meta_value* | **Meta_key** | *Meta_value* 

因此,每行一个帖子,同一行中的元信息.

编辑：有了S-ha-dum,我已经设法得到了一些方法,但我有大约12个Meta_value> Meta_key值要退出数据库,所以我需要帮助来编写查询的其余部分

SELECT *,(SELECT Meta_value FROM wp_postMeta WHERE wp_postMeta.Meta_key = 'Publisher' AND wp_postMeta.post_id = wp_posts.ID) as Publisher FROM wp_posts

解决方法:

一位朋友最终设法帮我解决了我的问题.这是他将包含元信息的所有帖子导出到CSV文件的最终SQL查询.
