簡單的mysql選擇問題

Question

我想在我的數據庫中選擇所有重複的行。我有見下表：

title  content 
aa   hahaha 
bb   weeeee 
cc   dddddd 
aa   ggggg 
aa   ggggggee 
dd   hhhhhhh 
bb   ggggggg 

我的查詢是

select count(post_title) as total, content from post group by post_title 

它只會顯示

total  content 
    3  hahaha 
    2  weeeeee 

，但我想顯示類似

total  content 
aa   hahaha 
aa   ggggg 
aa   ggggggee 
bb   weeeeeee 
bb   geeeeeee 

不知道是什麼要做，我認爲這可能很簡單。謝謝您的幫助。

Answer 1

Select title, content 
From table_name 
Where title In 
    (Select title From Table 
    Group By title 
    Having COUNT(*) > 1) 

（從Multiple NOT distinct）

Answer 2

據我所知，SQL查詢應該是這樣的：

SELECT post_title, content 
FROM post 
GROUP BY post_title, content 

Answer 3

嘗試用類似

SELECT total, content FROM post 
    WHERE id IN ( 
    SELECT id FROM post 
     GROUP BY post_title 
     HAVING count(post_title) > 1 
    )
