重复主题标题搜索从1海报

Question

我有一个旧的论坛。在这个论坛有很多双重主题（相同标题）。我发现这个选择所有的双主题标题：

SELECT topic_title, topic_time, forum_id, topic_first_post_id, topic_first_poster_name, topic_id, topic_poster, COUNT(*) TotalCount 
FROM phpbb3_topics 
GROUP BY topic_title 
HAVING COUNT(*) >1 

现在我想从同一个人topic_poster

请你告诉我一个解决方案的所有双主题标题？请编辑我暴露出来的选择中，以示与同topic_poster ID所有双主题标题的方式（topic_poster是ID字段）

非常感谢您

Answer 1

试试这个：

SELECT topic_poster_id, topic_title, topic_time, forum_id, topic_first_post_id, topic_first_poster_name, topic_id, topic_poster, COUNT(*) TotalCount 
FROM phpbb3_topics 
GROUP BY topic_poster_id, topic_title 
HAVING COUNT(*) >1

你可以通过添加topic_poster到组：

SELECT topic_title, topic_time, forum_id, topic_first_post_id, topic_first_poster_name, topic_id, topic_poster, COUNT(*) TotalCount 
FROM phpbb3_topics 
GROUP BY topic_title, topic_poster 
HAVING COUNT(*) >1
