Find duplicate records in MySQL

Question

I want to pull out duplicate records in a MySQL Database. This can be done with:

SELECT address, count(id) as cnt FROM list
GROUP BY address HAVING cnt >         


        

Answer 1

select * from table_name t1 inner join (select distinct  from table_name as temp)t2 where t1.attribute_name = t2.attribute_name

For your table it would be something like

select * from list l1 inner join (select distinct address from list as list2)l2 where l1.address=l2.address

This query will give you all the distinct address entries in your list table... I am not sure how this will work if you have any primary key values for name, etc..
