php - 来自 1 张海报的重复主题标题搜索

Question

我有一个旧论坛。在这个论坛中有许多双重主题（相同的标题）。我发现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

现在我想要同一个人的所有双主题标题topic_poster

你能告诉我一个解决方案吗？请编辑我的存在选择以显示所有相同的双主题标题topic_poster ID（topic_poster 是一个 ID 字段）

非常感谢

Answer 1

您可以通过以下方式将其添加topic_poster到您的组中：

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

Answer 2

尝试这个：

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
