well, i moved a database from my computer to my site
what i did is in phpMyAdmin:
select the database on the left
on the top, there is a export option, click it
check the box saying save as file
download the .sql file
[if you already did the above, start here]
you will need to create the database first,
access your site phpMyAdmin, (C-Panel)
go to the new database,
click on import on the top,
select the file to upload
it should work, unless there is a limit for the upload size
if there is a limit, you could make a request for the admins to upload it for you
