WP tbl joins.. DBA'rs help
 

Am looking to return term_id, name and slug from wp_terms. These term_id's need to be associated to post_id's that reside in wp_post_meta where wp_postmeta.meta_key='wpb_post_views_count'

I also need those results ordered by : order by cast(wp_postmeta.meta_value as signed) desc;

just having problems associating back out... here are the tbls possibly involved

try here

Put this together real quick so don't know if it is 100% correct or not:

select c.term_id, c.name as term_name, c.slug as term_slug from wp_posts a
inner join wp_term_relationships b on a.id=b.object_id
inner join wp_term_taxonomy c on b.term_taxonomy_id=c.term_taxonomy_id
inner join wp_terms d on c.term_id=d.term_id
inner join wp_post_meta e on a.id=e.post_id
where e.meta_key='wpb_post_views_count'
order by cast(e.meta_value as signed) desc

Awesome thank you!!!! Small changes here there.. but that was the connection I was looking for!! Thank you very much!!!
:thumbsup

curious why you are using a sql call rather than a wp query?

You're welcome.

If you are asking me I just went into one of my wife's wp dbs to figure out the relationships. I am well versed in databases but not so much in wp.

If you are asking the OP, I will let him answer ;p
