从1张海报中复制主题标题搜索

Question

我有一个旧论坛。在这个论坛上有很多双主题（同名）。我找到了所有具有此选择的双主题标题：

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

现在我想要来自同一个人topic_poster

的所有双主题标题 你能告诉我一个解决方案吗？请编辑我的existend选择，以显示具有相同topic_poster ID的所有双主题标题（topic_poster是ID字段）

非常感谢

Answer 1

您可以通过以下方式将topic_poster添加到您的论坛：

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

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
