Using CI to populate a database from a sql file

[eluser]skunkbad[/eluser]
I'm just playing around with trying to get CI to populate a database with an SQL file:

Code:

$sql = @file_get_contents('sql/db.sql');

$this->db->simple_query( $sql );

I don't want to use db forge, because it's more work than it's worth, especially to maintain. The problem I'm running into with the above code is that I get no kind of feedback as to why it's not working. I can copy and paste my SQL straight into phpMyAdmin, and it works great, but no love from CI. Anybody got ideas?

Here's the SQL in case it means anything to you:
