SQL - Select a variable that needs to be populated - mysql

Question

Long time no see !
I'm using wordpress for my site with lots of custom post_type and multiple category system with toxonomies set by the Toolset plugin.
I'm trying to store some posts into a mysql table from a huge query that i want to cron each night to increase speed of my site.
Here is what I did :
SELECT wp_posts.ID as mid,wp_posts.post_title,wp_posts.post_name,(
SELECT COUNT(wp_posts.ID) FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id ) INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id ) LEFT JOIN wp_icl_translations t
ON wp_posts.ID = t.element_id
AND t.element_type = CONCAT('post_', wp_posts.post_type) WHERE 1=1 AND (
( wp_postmeta.meta_key = 'my_key' AND wp_postmeta.meta_value = mid )
AND
(
( mt1.meta_key = 'end_date' AND CAST(mt1.meta_value AS SIGNED) >= date_format(curdate(), '%Y%m%d') )
OR
( mt1.meta_key = 'end_date' AND CAST(mt1.meta_value AS SIGNED) = '' )
)
) AND wp_posts.post_type IN ('bp','code') AND ((wp_posts.post_status = 'publish'))
) AS countpost
FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id ) WHERE 1=1 AND ( ( wp_postmeta.meta_key = 'top-key' AND wp_postmeta.meta_value = 'yes' ) ) AND wp_posts.post_type = 'my_type' AND ((wp_posts.post_status = 'publish')) GROUP BY wp_posts.ID ORDER BY wp_posts.post_title
It work great but i want to add a column !
The columni want should look like an "array" of "term_taxonomy_id" of the "COUNT(wp_posts.ID) query result" like this :
SELECT group_concat(term_taxonomy_id) FROM `bpo_term_relationships` WHERE `object_id` = id_of_the_current_post_scanned_by_count_query
my result should look like this
bpo_posts.ID | bpo_posts.post_title | bpo_posts.post_name | COUNT(bpo_posts.ID) | "array" of "term_taxonomy_id"
1 | the title | the-title | 16 | 815,712,1025
2 | hey you | hey-you | 5 | 75,105,200
...
...
I'm stuck :(
Anybody has an idea ?
Thanks.

Answer 1

I finally achieve what I wanted to do !
Here is the code :
ALTER EVENT wp_mytable
ON SCHEDULE EVERY 1 DAY
STARTS '2016-12-02 01:00:00'
DO
INSERT INTO wp_mytable (mid, name, title, cats, posts)
SELECT wp_posts.ID as mid, #titlex := wp_posts.post_title, #namex := wp_posts.post_name,(
SELECT group_concat(DISTINCT term_taxonomy_id) FROM `wp_term_relationships` WHERE `object_id` IN (
SELECT wp_posts.ID as idx FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id ) INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id ) LEFT JOIN wp_icl_translations t
ON wp_posts.ID = t.element_id
AND t.element_type = CONCAT('post_', wp_posts.post_type) WHERE 1=1 AND (
( wp_postmeta.meta_key = 'my-key' AND wp_postmeta.meta_value = mid )
AND
(
( mt1.meta_key = 'end_date' AND CAST(mt1.meta_value AS SIGNED) >= date_format(curdate(), '%Y%m%d') )
OR
( mt1.meta_key = 'end_date' AND CAST(mt1.meta_value AS SIGNED) = '' )
)
) AND wp_posts.post_type IN ('bp','code') AND ((wp_posts.post_status = 'publish'))
)
) as cats,#countpostx := (
SELECT COUNT(wp_posts.ID) FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id ) INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id ) LEFT JOIN wp_icl_translations t
ON wp_posts.ID = t.element_id
AND t.element_type = CONCAT('post_', wp_posts.post_type) WHERE 1=1 AND (
( wp_postmeta.meta_key = 'my-key' AND wp_postmeta.meta_value = mid )
AND
(
( mt1.meta_key = 'end_date' AND CAST(mt1.meta_value AS SIGNED) >= date_format(curdate(), '%Y%m%d') )
OR
( mt1.meta_key = 'end_date' AND CAST(mt1.meta_value AS SIGNED) = '' )
)
) AND wp_posts.post_type IN ('bp','code') AND ((wp_posts.post_status = 'publish'))
) AS countpost
FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id ) WHERE 1=1 AND ( ( wp_postmeta.meta_key = 'top-key' AND wp_postmeta.meta_value = 'yes' ) ) AND wp_posts.post_type = 'my_type' AND ((wp_posts.post_status = 'publish')) GROUP BY wp_posts.ID ORDER BY wp_posts.post_title
ON DUPLICATE KEY
UPDATE `name`=#namex, `title`=#titlex, `posts`=#countpostx, `cats`=cats
Not sure this could be better but it works :)
Ask if you need some explanation :)
