Deprecated - Database compatibility

Hi everyone
after installing and configuring my site in localhost (with easy php) every works great. Now i want to publish it on the web. I've just open a free account in awardspace.com (php hosting and mysql). They give me a database name that i can't change, same thing for username and password. Where can i change the settings for the connection to the database (put the right url, name, account for the db)? Settings.php? database.mysql.inc (inside includes)?
thanks Luca

Hey guys,

I am (fairly) new to drupal, when I reccomended for my sporting organisation to go with a specific hosting company I didn't do my research properly. My search box didnt work, because my hosting provider does not give out the mysql CREATE_TEMPORARY_TABLES right/permission.
I tried using trip_search. I didnt like it. I tried some patches from other people and couldnt get it to fly without other problems.

I 'invented' a solution: remove drupals db_query_temporary function and replace it with my own.

Does anyone know the recommendation on using subqueries in drupal modules? Since they're not supported before mysql 4.1 I'm not sure if it's something that should be avoided, or is ok as long as it's noted...
