Everytime I try restoring the dump, I get :
ERROR 1062 (23000) at line 10297: Duplicate entry 'spaß' for key 'PRIMARY'
I am trying to restore it using:
mysql -u root -ppassword database < 0719.sql
You could import the dump into a temporary table, than use an SQL statement to copy only rows from this temporary table which do are not found in the target table.
