简单的mysql选择问题

Question

我试图选择我的数据库中的所有重复行.我有下表:

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

我的疑问是

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

它只会显示

 total        content
    3        hahaha
    2        weeeeee

但我想表现出类似的东西

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

不知道该怎么办,我认为这可能很简单.谢谢您的帮助.

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