i want to retrieve custom posts using using custom query . my taxonomy is recipe_tx and terms (Beef) , (Chicken) etc in it .

i have tried using

SELECT p.* FROM wp_posts p, wp_term_taxonomy tt, wp_term_relationships tr 
WHERE p.ID=tr.`object_id` 
AND tt.`term_id`=tr.`term_taxonomy_id` 
AND (p.post_type = 'recipe_cpt')
AND p.post_status = 'publish'
AND tt.`term_taxonomy_id` = 37

but no luck .

can someone help me how to get wp posts by their term_id .

if beefs id is 37 then i want to retrieve all the posts with term_id = 37

Have you tried using the WP_Query class? You might find it's easier to use the built-in tools for this instead of a custom query from scratch. Something similar to the following should work for you:

$args = array(
'post_type' => 'recipe_cpt',
'tax_query' => array(
    'taxonomy' => 'recipe_tx',
    'field' => 'term_id',
    'terms' => 37
$query = new WP_Query( $args ); ?>

EDIT: note the tax_query is an array of arrays by design. Many tax query problems are a result of missing this detail.

EDIT: corrected field value typo above, replacing 'id' with 'term_id'.


I know the question is answered, but if anyone is trying to achieve the same with a raw SQL query, you could try the following:

FROM wpiw_posts
    SELECT object_id 
    FROM wpiw_term_relationships AS TR 
        INNER JOIN wpiw_term_taxonomy AS TT ON TR.term_taxonomy_id = TT.term_taxonomy_id
        INNER JOIN wpiw_terms AS T ON TT.term_id = T.term_id
    WHERE TT.taxonomy = 'recipe_tx' AND T.term_id = 37

The above query will get you all the posts that belong to the given taxonomy (recipe_tx) and term ID (37).

I know that this is an old post, but I just wanted to chime in. @jdm2112 is correct. Just use the WP_Query class. This makes sure that if the database structure is ever updated in the future, your query still works.... However, since it looks like you are looking for a raw SQL answer, this is the actual SQL that WP_Query would execute... at least as of WordPress 5.6. (I've adapted the SQL to your question)

SELECT * from wp_posts 
        wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id)
        (wp_term_relationships.term_taxonomy_id IN (37)) AND
        wp_posts.post_type = 'recipe_cpt' AND
        wp_posts.post_status = 'publish'
    GROUP BY wp_posts.ID

You can get the the actual query by creating a WP_Query instance, then look at the request property like so:


$args = [
    'post_type' => 'recipe_cpt',
    'tax_query' => [
            'taxonomy' => 'recipe_tx',
            'field' => 'term_id',
            'terms' => 37
$queryObj = new WP_Query($args); 

// This will give you the actual raw SQL query
$rawSqlQuery = $queryObj->request;
