Table MYSQL query - mysql

Question

I have used WPAllImport to import data from a CSV-file to Advanced Custom Fields.
I now want to put them back together with a SQL query, but dont know how to do it.
I've tried WPDataTables, but when I choose 5 or more tables, WPDataTables stops.
If I pick 2, I get this code
SELECT posts_podukter.post_title AS podukter_post_title,
podukter_meta_produkter_0_pris_tbl.meta_value AS podukter_meta_produkter_0_pris
FROM beta_h3L_posts AS posts_podukter
INNER JOIN (SELECT podukter_meta_produkter_0_pris_tbl_posts.ID as id, meta_value, meta_key FROM beta_h3L_postmeta AS podukter_meta_produkter_0_pris_tbl_postmeta INNER JOIN beta_h3L_posts AS podukter_meta_produkter_0_pris_tbl_posts ON podukter_meta_produkter_0_pris_tbl_postmeta.post_id = podukter_meta_produkter_0_pris_tbl_posts.ID AND podukter_meta_produkter_0_pris_tbl_posts.post_type = 'podukter') AS podukter_meta_produkter_0_pris_tbl
ON podukter_meta_produkter_0_pris_tbl.meta_key = 'produkter_0_pris' AND podukter_meta_produkter_0_pris_tbl.id = posts_podukter.ID
WHERE 1=1
AND posts_podukter.post_type = 'podukter'
I think this is too much code.
Can someone help me to get on the right way.... :-)
This is what the table should look like
Here is a capture how the table should look like

I would agree that this is "too much code" which sounds sort of ridiculous, but in this case totally applies. That SQL statement that was produced could be written as:
SELECT
post.post_title as podukter_post_title,
postmeta.meta_value as podukter_meta_produkter_0_pris
FROM beta_h3L_posts AS posts
INNER JOIN beta_h3L_postmeta AS postmeta
ON postmeta.post_id = post.ID
AND postmeta.meta_key = 'produkter_0_pris'
WHERE posts.post_type = 'podukter'
If there is another metavalue that you need you can join again to your meta table:
SELECT
post.post_title as podukter_post_title,
postmeta.meta_value as podukter_meta_produkter_0_pris,
postmeta2.meta_value as tilbudspris
FROM beta_h3L_posts AS posts
INNER JOIN beta_h3L_postmeta AS postmeta
ON postmeta.post_id = post.ID
AND postmeta.meta_key = 'produkter_0_pris'
INNER JOIN beta_h3L_postmeta AS postmeta2
ON postmeta.post_id = post.ID
AND postmeta2.meta_key = 'tilbudspris'
WHERE posts.post_type = 'podukter'
I don't know what any of these words mean (besides post and postmeta) so I'm just going to assume that this is right/helpful.
The only thing is that you may want to switch to using a LEFT OUTER JOIN to your postmeta table just in case the meta_key you are after doesn't exist for the post.id you are querying. In that case, with an INNER JOIN the id/post will be dropped from the result set where a LEFT OUTER JOIN will show the id/post record with a blank for whatever that corresponding meta_value is that you are joining in.
