Not sure what kind of access you need to have for this, but if your db is already created, and you just need to dump the sql into it:
mysql -hHOSTNAME -uUSER -pPASSWORD DATABASE < DUMPED_TEXTFILE.sql
Maybe that will help, also talk to your hosting company, they might have phpMyAdmin installed, if they do USE IT. If not, tell them to get it.
