我正在寻找编写一个自定义 SQL 语句，该语句将从匹配 2 个不同类别的 Wordpress 数据库中提取已发布的帖子。
Category 1 (Static) = "Website-1"
Category 2 (Dynamic) = "News", "Tips", "Recreation", etc.
这有点超出我的领域，所以任何帮助将不胜感激。
这是我到目前为止所拥有的：
select p.* from wp_terms wt
join wp_term_taxonomy t on wt.term_id = t.term_id
join wp_term_relationships wpr on wpr.term_taxonomy_id = t.term_taxonomy_id
join wp_posts p on p.id = wpr.object_id
where
t.taxonomy = 'category' and
wt.name = 'Website-1' and
p.post_status = 'publish'
group by p.id
order by p.post_date desc
limit 10
它将拉第一个类别没问题，但我需要它匹配 2 个类别。
任何见解将不胜感激。
谢谢！
我想出的解决方案：
select p.* from wp_posts p
join wp_term_relationships tr on p.id = tr.object_id
join wp_term_taxonomy tt on tt.term_taxonomy_id = tr.term_taxonomy_id
join wp_terms t on t.term_id = tt.term_id
where p.id in
(select tr2.object_id from wp_term_relationships tr2
join wp_term_taxonomy tt2 on tt2.term_taxonomy_id = tr2.term_taxonomy_id
join wp_terms t2 on t2.term_id = tt2.term_id
where
tt2.taxonomy = 'category' and
t2.name in ('Website-1') and
p.id = tr2.object_id
) and
p.post_status = 'publish' and
tt.taxonomy = 'category' and
t.name in ('News')
group by p.id
order by p.post_date desc
limit 10
我确信有更好的方法来编写这个查询，因为它非常混乱，但它现在可以工作。
