在MySql Godaddy VPS Cpanel中使用sql_mode = only_full_group_by获取MYSQL错误

Posted 2023-01-12

嗨，我在使用godaddy-vps服务器时正在使用phpMYAdmin mysql，在执行SQL查询时出现错误

我希望基于posts.user_id = 2个帖子列表通过在likes表中的likes.post_id总数，通过likes.post_id = posts.id将两个表合并在一起，其中likes_status ='true'

SELECT likes.post_id, likes.like_status, P.id, P.user_id, 
  count(*) AS likeCountProfilePosts  FROM likes 
  INNER JOIN posts AS P ON P.id=likes.post_id  
  WHERE P.id IN (SELECT id FROM posts WHERE posts.user_id =2) 
  AND likes.like_status='true' 

出现错误：

＃1140-在没有GROUP BY的聚合查询中，SELECT列表的表达式＃1包含非聚合列'howtags_social_db.likes.post_id';这与sql_mode = only_full_group_by

不兼容

如果有人知道解决方案，请告诉我

答案

我刚刚更新了我的SQL查询，它对我来说很好用，而不是更改PHPMyAdmin设置

 SELECT comments.post_id,  
  count(*) AS commentCount FROM comments  
  INNER JOIN posts AS P on P.id=comments.post_id  
  GROUP BY comments.post_id  
  ORDER BY comments.post_id DESC
