mysql通过排除group by删除记录组

Question

我有一张这样的表：

| id | EAN | supplier_code |
|0001|11111|         aaaaaa|
|0002|22222|         aaaaaa|
|0003|33333|         bbbbbb|
|0004|33333|         cccccc|
|0005|11111|         aaaaaa|

我必须删除3和4之类的ID，因为它们是脏数据。 如何编写选择以找到它们？

类似这样的事情

SELECT id, EAN, supplier_code, COUNT( id ) AS NumDuplicati
FROM table
WHERE supplier_code <>  ""
GROUP BY EAN
HAVING NumDuplicati >1

但我不能删除ID 1和5 ......

UNTESTED：不确定你是否可以区别于......

delete from yourTable where EAN in (
Select EAN
FROM yourTable
Group by EAN
having count(distinct supplier_Code ) > 1)
