在单个MySQL查询中获取带有POST META的帖子ID

如何解决在单个MySQL查询中获取带有POST META的帖子ID

从POSTS-> ID中，我想要前12个ID，其中post_type ='product' 通过该ID关联，我想获取所有POST Meta。

我正在使用此MySQL查询，但它不起作用：

SELECT posts.ID,postMeta.Meta_key,postMeta.Meta_value FROM `wp_u8gwgg_posts` as posts

INNER JOIN wp_u8gwgg_postMeta as postMeta on posts.ID = postMeta.post_id

WHERE 

posts.`post_type` = 'product' AND 
posts.post_status = 'publish'

ORDER BY posts.ID

这给了我多余的数据post_id。

Post ID | Meta Key       | Meta Value
++++++++++++++++++++++++++++++++++++++
12      | _sku           | 18945236
12      | _price         | 1569.36
12      | _regular_price | 1496.20

我希望结果为：

Post ID | Meta Key                     | Meta Value
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
12      | _sku,_price,_regular_price | 18945236,1569.36,1496.20

如果可能，请让我解决。

OR

如果有更好的解决方法，也欢迎您。

谢谢

解决方法

SELECT posts.ID,GROUP_CONCAT(postmeta.meta_key ORDER BY posts.ID) meta_keys,GROUP_CONCAT(postmeta.meta_value ORDER BY posts.ID) meta_values 
FROM wp_u8gwgg_posts as posts
INNER JOIN wp_u8gwgg_postmeta as postmeta on posts.ID = postmeta.post_id
WHERE posts.post_type = 'product' 
  AND posts.post_status = 'publish'
GROUP BY posts.ID
ORDER BY posts.ID
