I'm pretty sure input redirects work in CMD so if the command line mysql client is in the path, you could try: mysql -p [database name] < peqdb_rev1589.sql.
You could also try a GUI tool like navicat or the official mysql management workbench. I haven't used either one, but the old query browser used to let you load from file.
