Meanwhile, you may want to take a look at the MySQL dump file you are trying to import. I suspect it may be trying to create a whole new database, and you will get an error if so.
If this is the case, your first step is to create the database using MySQL Databases or the Wizard
Don’t forget to add a username / password with privileges to the new database
Your next step, is to create a copy of the import file and change/edit the lines where the database is created by deleting or changing it to comment, so you can only import the tables and contents if any.
Please note that you will have to edit your scripts to reflect the new database/user/psw.
