SQLDumpSplitter is a fantastic time saver – especially if you have shared hosting that imposes upload file size limits.
SQLDumpSplitter will allow you to automatically split your sql database at any size you choose that can then be imported with a tool like phpMyAdmin. If your database was too big to import into phpmyadmin, it won’t be anymore.
You can also choose to skip Comment-Lines if required.
