MySQL是否更新这些阵列上的表？

我有这样一个问题：

SELECT DISTINCT(wp.`ID`), wps.sku AS sku
FROM `wp_posts` AS wp
INNER JOIN `wp_postmeta` AS wpm ON (wpm.`post_id` = wp.`ID` AND wpm.`meta_key` = '_sku' AND wpm.`meta_value` = '')
INNER JOIN `wp_product_skus` AS wps ON (wps.`id_product` = wpm.`post_id`)
WHERE wp.`post_parent` = 0 AND wp.`post_type` = 'product' AND wp.`ID` NOT IN (SELECT post_parent FROM wp_posts WHERE post_parent != 0 AND post_type = 'product_variation')

它返回如下输出：

我需要对

wp_postETA

表中与

post_id

=

id

匹配的所有id执行更新，并使用上述pic中的sku值更新

sku

的meta_值

---

如何在MySQL查询中完成这一切？

您想根据需要对其他表执行

更新
，如

UPDATE `wp_posts` wp
INNER JOIN `wp_postmeta` wpm ON wpm.`post_id` = wp.`ID` 
AND wpm.`meta_key` = '_sku' 
AND wpm.`meta_value` = ''
INNER JOIN `wp_product_skus` wps ON wps.`id_product` = wpm.`post_id`
WHERE wp.`post_parent` = 0 
AND wp.`post_type` = 'product' 
AND wp.`ID` NOT IN (
SELECT post_parent FROM wp_posts 
WHERE post_parent != 0 
AND post_type = 'product_variation'
)
SET wp.sku = wps.sku

（或）通过直接加入
选择
结果集，如下所示

UPDATE `wp_posts` wp
JOIN 
(
SELECT DISTINCT wp.`ID`, 
wps.sku AS sku
FROM `wp_posts` wp
INNER JOIN `wp_postmeta` AS wpm ON wpm.`post_id` = wp.`ID` 
AND wpm.`meta_key` = '_sku' 
AND wpm.`meta_value` = ''
INNER JOIN `wp_product_skus` wps ON wps.`id_product` = wpm.`post_id`
WHERE wp.`post_parent` = 0 
AND wp.`post_type` = 'product' 
AND wp.`ID` NOT IN (
SELECT post_parent FROM wp_posts 
WHERE post_parent != 0 
AND post_type = 'product_variation') 
) TAB ON wp.ID = TAB.ID
SET wp.sku = TAB.sku

这里有多个mysql查询将向您展示如何进行查询。你先做过研究吗？谷歌搜索“MySQL update table with select”更新
wp_postemta
表，但这对该表的效果相同。干杯：）太好了。那么a+1可以是：）
