its not the way you load it thats the issue.. however as there is not much to go on.. apart from you have a blank page you may have to search the forums and do a bit of fault diagnosis here are some links I found yesterday.

you could try setting the log_threshold in your config file see if that gives you any clues, if not add some logging in the driver code your self (look in the database directory)
check your config/database.php are you using the right drivers?
does your version of php have sql compiled in?
