Delete duplicate rows using DELETE JOIN statement MySQL provides you with the DELETE JOIN statement that you can use to remove duplicate rows quickly.

The following statement deletes duplicate rows and keeps the highest id:

DELETE t1 FROM contacts t1
    INNER JOIN
contacts t2 WHERE
t1.id < t2.id AND t1.email = t2.email;
