Wordpress MySQL查询帖子类型

Question

我想在此查询中添加post_type选项。我该怎么办？

$state = $wpdb->get_results(" SELECT meta_value AS state, COUNT(post_id) AS count FROM {$wpdb->postmeta} WHERE meta_key = 'personal_nation' GROUP BY state ORDER BY state DESC");

Answer 1

尝试此查询

SELECT meta_value AS state, COUNT(post_id) AS count, post_id 
FROM wp_postmeta WHERE meta_key = 'personal_nation' 
AND post_id in(select ID from wp_posts where post_type="post") 
GROUP BY state ORDER BY state DESC
