Alternative Way to Import SQL to MYSQL
This solution could be of help. For scheduling, you'll have to do what is outlined here. You can connect to an Express instance using MySQL WorkBench as outlined here, but you can't schedule jobs.

Also, have you considered using ODBC to connect and send the data to another (i.e. MySQL) server. You can schedule many of these systems also!

Or try JDBC using SQuirreL SQL or DBeaver? Personally, I can recommend SQuirreL SQL! If you want to schedule a job using Java, try the solution here! Just be aware that your dumps may not be internally consistent unless you are careful about your transactions!
