这样就能找出d_name重复的
select d_name
from tbl_vod
group by d_name having count(1) > 1

如果要所有记录
select *
from tbl_vod where d_name in (select d_name
from tbl_vod
group by d_name having count(1) > 1)追问#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'select max(d_id) from tbl_vod group by d_name )' at line 4
