I'm looking to execute a raw SQL query in a Zend Controller. 

I looked here <http://framework.zend.com/manual/1.11/en/zend.db.statement.html> and it says to do 

```
    $sql = 'SELECT * FROM bugs WHERE reported_by = ? AND bug_status = ?';

    $stmt = new Zend_Db_Statement_Mysqli($db, $sql);

    $stmt->execute(array('goofy', 'FIXED'));

```

but whenever I do that it gives me an error cause of the $db.... What's $db supposed to hold cause it doesn't say anywhere in the documentation...

Also whenever I'm done I would like to return an array with whatever the result was, what would I be able to do something like `$resultArray = $stmt->execute(array('goofy', 'FIXED'));` ???

Thanks,
