Uploading Database

this is my first time doing this and I’m having trouble uploading an SQL database and assigning a domain to it.
can anyone give me feedback on this

Go to goodies and create a database. Once it is created (may take 15mins) logon using the web login – the link is in Goodies/MySql
The web login takes you to a version of phpMyAdmin and you can just enter the SQL code to create the tables etc.

I already have a database created, now i want to upload an SQL database i have.
