如何排除SQL语句中的某个类别

Question

这是我现在的代码，可以从wordpress wp_post表中获得热门的帖子。我如何排除3或4等类别？

$popularposts = "SELECT ID,post_title FROM {$wpdb->prefix}posts WHERE post_status = 'publish' AND post_type = 'post' ORDER BY comment_count DESC LIMIT 0,".$pop_posts; 
$posts = $wpdb->get_results($popularposts); 

Answer 1

后 '发布' 你添加（假设categorie领域是categorie）

and categorie not in ('3', '4') 

，或者，如果categorie是数字：

and (categorie < 3 or categeorie > 4) 

Answer 2

荣登网站通过网络和计算器，几乎解决了这个问题。仍然需要添加

ORDER BY comment_count DESC LIMIT 0,".$pop_posts 

以下代码中的某处。

$popularposts = "SELECT * FROM $wpdb->posts 
INNER JOIN $wpdb->term_relationships ON($wpdb->posts.ID = $wpdb->term_relationships.object_id) 
INNER JOIN $wpdb->term_taxonomy ON($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id) 

WHERE ($wpdb->term_taxonomy.term_id <> 3 
    AND $wpdb->term_taxonomy.term_id <> 4 
    AND $wpdb->term_taxonomy.taxonomy = 'category' 
    AND $wpdb->posts.post_type = 'post' 
    AND $wpdb->posts.post_status = 'publish')";
