To get a list of WordPress Posts using meta query in MySQL, you can use the following SQL query:

SELECT p.ID, p.post_title, m.meta_id, m.meta_key, m.meta_value FROM `wp_posts` p
LEFT JOIN `wp_postmeta` m ON p.ID = m.post_id
WHERE m.meta_key = 'wpcf-show-status'
AND m.meta_value <> ''  
ORDER BY p.post_title ASC

This query will create a list with ID, post title, meta key and meta value that fits to this WHERE clause. You need to update meta_key and meta_value values before running on your database. Otherwise you will get an empty result set.
