I have a sql file that I want to be dumped into a MySQL database that I have in Heroku using the ClearDB addon. When dumping in local I do the following:
mysql
You might be able to do something like this
mysql --host=us-cdbr-east.cleardb.com --user=b5xxxxx7 --password=37d8faad --reconnect heroku_xxxxxx < my_dump_file.sql
