I'm using WordPress. I want to get everything from the wp_posts table and two values from the postmeta table.
The "wp_postmeta" has the columns "post_id", "meta_key", and "meta_value".
So far, I'm able to get one of the "meta_value":
SELECT wp_post.*, $wpdb->postmeta.meta_value AS votes
FROM wp_posts
INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )
WHERE post_type='post'
AND wp_postmeta.meta_key = 'votes'
However, I also want to get another "meta_value" with the same "post_id" but a different "meta_key". How can I extend this query to the "meta_value"?
If you don't want multiple rows per post, you can do this by having multiple joins:
SELECT wp_post.*, metavotes.meta_value AS votes, metaother.meta_value AS other
FROM wp_posts
INNER JOIN wp_postmeta metavotes
ON ( wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = 'votes')
INNER JOIN wp_postmeta metaother
ON ( wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = 'other')
WHERE post_type='post'
(this assumes there is always exactly 1 row for each piece of metadata in wp_postmeta. I'm not familiar enough with wordpress to know whether this is the case. If metadata is optional, use LEFT OUTER JOIN's instead. If you can have multiple, what kind of output do you want?)
How about adding your additional meta_key to the query with the IN clause. Let's say it's the string value foo that you want to add:
SELECT wp_post.*, $wpdb->postmeta.meta_value AS votes
FROM wp_posts
INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )
WHERE post_type='post'
AND wp_postmeta.meta_key IN ('votes', 'foo');
Maybe try something like this:
SELECT wp_posts.*, wp_postmeta.meta_value, wp_postmeta.meta_key
FROM wp_posts INNER JOIN wp_postmeta ON(wp_posts.ID = wp_postmeta.post_id)
WHERE wp_posts.post_type='post'
AND wp_postmeta.meta_key IN ('votes', ...)

Hello I have a WordPress database just updated to my site to a new theme and my Product specification is missing in new theme I try to find and found new theme using a different table column to show the specification so I have to replace product specifications in the new column.
Following the original data
Table Name: wp_postmeta
SELECT
wp_postmeta.post_id,
wp_postmeta.meta_value,
wp_postmeta.meta_key
FROM
wp_postmeta
WHERE
wp_postmeta.meta_key = '_specifications'
ORDER BY
wp_postmeta.post_id
ASC
I want to replace above data in following table with matching ID
Table Name: wp_posts
SELECT
wp_posts.ID,
wp_posts.post_content
FROM
wp_posts
ORDER BY
wp_posts.ID
ASC
You can update the table wp_posts by joining it to your first query.
update wp_posts p inner join (
select post_id, meta_value
from wp_postmeta
where meta_key = '_specifications'
) m on m.post_id = p.id
set p.post_content = m.meta_value
I want to search a variable in a string in database in inner join condition statements. I want to raplace wp_idpl_orders.product_id with % in ign_product_level_%_price in the below query. How can I do this?
SELECT * FROM `wp_idpl_orders` INNER JOIN wp_postmeta WHERE wp_postmeta.meta_key like "ign_product_level_%_price" and wp_postmeta.meta_key like wp_idpl_orders.product_id and wp_postmeta.post_id = wp_idpl_orders.post_id
MySQL CONCAT() function is used to add two or more strings.
SELECT * FROM `wp_idpl_orders` INNER JOIN wp_postmeta WHERE wp_postmeta.meta_key like concat("ign_product_level_",wp_idpl_orders.product_id,"_price") and wp_postmeta.post_id = wp_idpl_orders.post_id
I am trying to SELECT (all of the multiple) comments from Wordpress which relate to a post (wp_comments.comment_content) with GROUP_CONCAT but I only want to select those comments which DON'T contain the text string "status". If there are no comments at all, or only comments which contain "status" I still want to see those records in the result, just without getting anything back for comments.
When I tried putting a condition similar to [WHERE wp_comments.comment_content NOT LIKE "%status%"] at the end of the complete query, records which only have a comment containing "status" don't display AT ALL, I still need to get those records, just without the comments.
I want to try something like the below version but this throws up an error and doesn't spit out any data at all. (The overall query works as expected btw apart from the comment selection section..).
Maybe I am joining the wp_comments table in the wrong place, using the wrong join, not using a properly formatted nested SELECT or similar, maybe it needs a separate SELECT at the end so I can get the comments back I want in a way which doesn't effect which records are selected overall.. not sure..
Any idea what I am doing wrong or how to approach this?
Here is my query, thanks in advance for any kind pointers!
select wp_woocommerce_order_itemmeta.meta_value as firstwoometavalue,
wp_postmeta.meta_value as firstwpmetavalue, Y.meta_value as ymetavalue,
Z.meta_value as zmetavalue, X.meta_value as xmetavalue,

I have to make a mysql select from a wordpress database :
SELECT wp_posts.ID, wp_posts.post_title AS post_title,
responsable.meta_value AS responsable,
nif_cliente.meta_value AS nif_cliente,
CONCAT_WS(' ',contactos_0_nombre.meta_value,CONCAT('<br><br>',contactos_1_nombre.meta_value)) AS contactos,
tipo_de_empresa.meta_value AS tipo_de_empresa,
tipo_cliente.meta_value AS tipo_cliente
FROM wp_posts
LEFT JOIN wp_postmeta AS responsable
ON wp_posts.ID = responsable.post_id AND responsable.meta_key='responsable'
LEFT JOIN wp_postmeta AS tipo_de_empresa
ON wp_posts.ID = tipo_de_empresa.post_id AND tipo_de_empresa.meta_key='tipo_de_empresa'
LEFT JOIN wp_postmeta AS nif_cliente
ON wp_posts.ID = nif_cliente.post_id AND nif_cliente.meta_key='nif_cliente'
LEFT JOIN wp_postmeta AS contactos_0_nombre
ON wp_posts.ID = contactos_0_nombre.post_id AND contactos_0_nombre.meta_key='contactos_0_nombre'
LEFT JOIN wp_postmeta AS contactos_1_nombre
ON wp_posts.ID = contactos_1_nombre.post_id AND contactos_1_nombre.meta_key='contactos_1_nombre'
LEFT JOIN wp_postmeta AS tipo_cliente
ON wp_posts.ID = tipo_cliente.post_id AND tipo_cliente.meta_key='tipo_cliente'
WHERE wp_posts.post_status = 'publish' AND wp_posts.post_type = 'clientes'"
I want to concate contactos_n_nombre. I can write it manual but 'n' it's dinamic (i don't know how much it is) It can be 0 if there are only one contact, but can be 1000 if this client have more contact methods.
How can i make it to search how many contactos have one client, and concate all of them
Thanks
If I understand your question correctly, you can use the MySQL GROUP_CONCAT function. You may need to adjust this for your situation, but the basic idea is:
Set up the database JOIN as:
LEFT JOIN wp_postmeta AS contactosdb ON wp_posts.ID = contactosdb.post_id
Then use the following in your SELECT:
GROUP_CONCAT(contactosdb.meta_value SEPARATOR '<br><br>') AS contactos
First I would like to mention I have limited skills when it comes to MYSQL an JOIN. However this is what I have and what I like to achieve:
I have the default WordPress tables and like to get a result with post_name, title, status and the meta_value from a certain meta key.
This is what I have:
SELECT
wp_posts.ID, wp_posts.post_name, wp_posts.post_title, wp_posts.post_status, wp_postmeta.meta_value
FROM wp_posts
INNER JOIN
wp_term_relationships ON ( wp_posts.ID = wp_term_relationships.object_id )
INNER JOIN
wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )
WHERE (
wp_term_relationships.term_taxonomy_id
IN ( 1, 2, 3 )
)
AND wp_posts.post_type = 'my_post_type'
AND (
wp_posts.post_status
IN (
'my_status_1', 'my_status_2'
)
)
AND wp_postmeta.meta_key = 'my_meta_key'
GROUP BY wp_posts.ID
ORDER BY wp_posts.ID ASC
Everything works as expected when each post has a postmeta of 'my_meta_key'. But if the 'my_meta_key' is missing the post is not in the result.
I guess it' caused by the second INNER JOIN but as mentioned I have no idea what I should it replace it with.
I'm sure it's something simple
Move the AND wp_postmeta.meta_key = 'my_meta_key' to
INNER JOIN
wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )
Like this and change the INNER for a LEFT
LEFT JOIN
wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id
AND wp_postmeta.meta_key = 'my_meta_key')
If you put your condition in the "Where Clause" The Left join will be "overwritten".
And I will add an advice. Dont use parenthesis when you dont really need it to keep your code easy to read.
The following returns
all records from WP_Posts
only those records with WP_TERM_RELATIONSHIPS
only those records in wp_postmeta which a matching record in wp_posts.
*
SELECT wp_posts.ID, wp_posts.post_name, wp_posts.post_title,
wp_posts.post_status, wp_postmeta.meta_value
FROM wp_posts
LEFT JOIN wp_term_relationships
ON wp_posts.ID = wp_term_relationships.object_id
LEFT JOIN wp_postmeta
ON wp_posts.ID = wp_postmeta.post_id
WHERE wp_term_relationships.term_taxonomy_id IN ( 1, 2, 3 )
AND wp_posts.post_type = 'my_post_type'
AND wp_posts.post_statusIN ('my_status_1', 'my_status_2')
AND (wp_postmeta.meta_key = 'my_meta_key' or wp_postmeta.meta_key is null)
GROUP BY wp_posts.ID
ORDER BY wp_posts.ID ASC
you need the is null otherwise records in wp_posts without wp_postmeta data will be excluded.
Change the INNER JOIN on the wp_postmeta table to a LEFT JOIN:
LEFT JOIN wp_postmeta
ON ( wp_posts.ID = wp_postmeta.post_id )
And move the WHERE filter for the wp_postmeta to the JOIN condition.
So your query will be:
SELECT wp_posts.ID, wp_posts.post_name, wp_posts.post_title, wp_posts.post_status, wp_postmeta.meta_value
FROM wp_posts
INNER JOIN wp_term_relationships
ON ( wp_posts.ID = wp_term_relationships.object_id )
LEFT JOIN wp_postmeta
ON ( wp_posts.ID = wp_postmeta.post_id )
AND wp_postmeta.meta_key = 'my_meta_key'
WHERE wp_term_relationships.term_taxonomy_id IN ( 1, 2, 3 )
AND wp_posts.post_type = 'my_post_type'
AND wp_posts.post_status IN ('my_status_1', 'my_status_2')
GROUP BY wp_posts.ID
ORDER BY wp_posts.ID ASC
The INNER JOIN syntax will only return rows that match in both tables. So if you do not have a matching row, you will not get any result. By changing that to a LEFT JOIN, you will return all rows even if there is not a matching row in the wp_postmeta table. If the row does not exist, then the values from the wp_postmeta table will be null.
