I've hit an issue trying to find out what products are missing suppliers on a website with tens of thousands of products.
I need an MySQL query to determine which products are missing the taxonomy "suppliers" through phpmyadmin.
So far I've pieced this together from various answers:
SELECT *
FROM wp_posts wp
INNER JOIN wp_postmeta wm ON (wm.`post_id` = wp.`ID`)
INNER JOIN wp_term_relationships wtr ON (wp.`ID` = wtr.`object_id`)
INNER JOIN wp_term_taxonomy wtt ON (wtr.`term_taxonomy_id` = wtt.`term_taxonomy_id`)
INNER JOIN wp_terms wt ON (wt.`term_id` = wtt.`term_id`)
AND wtt.`taxonomy` = 'suppliers'
WHERE post_type = 'product'
GROUP BY wp.ID
I've tried numerous things and cannot get it to work.

The problem is with you query is that you are not excluding product that has if pickerview == "back paddock"
do (this...)
else if pickerview == "Front Paddock"
do (this instead...)
that that product has some other attributes, so you can use suppliers or NOT EXIST, I have written the query using NOT IN.
NOT EXISTAnother version which will be a bit faster if you know all the SELECT *
FROM wp_posts wp
INNER JOIN wp_postmeta wm ON wm.`post_id` = wp.`ID`
INNER JOIN wp_term_relationships wtr ON (wp.`ID` = wtr.`object_id`)
INNER JOIN wp_term_taxonomy wtt ON wtr.`term_taxonomy_id` = wtt.`term_taxonomy_id`
INNER JOIN wp_terms wt ON wt.`term_id` = wtt.`term_id`
WHERE post_type = 'product'
AND NOT EXISTS
(SELECT `object_id`
FROM `wp_term_relationships` AS wtr_inner
WHERE `term_taxonomy_id` IN
(SELECT term_taxonomy_id
FROM `wp_term_taxonomy`
WHERE `taxonomy` = 'suppliers')
AND wtr.object_id = wtr_inner.object_id )
GROUP BY wp.ID
suppliers So you can modify the above query as
term_taxonomy_idHope this helps!
