[SOLVED] URGENT!!! database name is written which configuration file?

[seldon.paul2]

I created database name d2t, but hosting said, they have to insert their own conventional prefix in front of d2t.
What do I need to do. I got export d2t.sql of the entire database.
What can I do?
Panic - ><

So, here is my idea.
I am going to create another name, identical with hosting company's requirement.
And they import d2t.sql into that new database.

Then, where do I have to change the shop to listen to the new name of database, not the old?

Its in config>settings.ini.php file
