Issues executing MySQL sql file
I've got an installer which installs MySQL (and other programs). Part of the installer installs a pre-setup database. If the user installs it on another drive besides C:, I need to modify several paths. I've written a MySQL .sql file to modify the database, but it seems MySQL 5 doesn't properly execute it. Instead, it just displays the default command line page.
Any ideas why?
