Wordpress can't identify database

Hi, I'm trying to install Wordpress on my server and ideally I should give the database a single name, ie. blog or wordpress, etc.
The problem is, my server gives the database a username and name, ie. myusername_blog. I've checked the Wordpress install help and apparently this is a known issue.
Has anyone else had this problem, and if so how did you resolve it?

 

What's your problem?
Just use myusername_blog as db name.

 

Just replace your database name in your Wordpress config file with myusername_blog (or whatever).

 

Thanks guys, have actually done that, Wordpress still doesn't recognize it,
will investigate further

 

Does your server have a management panel like Plesk or cPanel?
You should have your DB settings in wp-config.php. Even though username, name and password are correct, you could be failing under host (most use localhost, but your host probably isn't).

Where are you hosting?
