 You can use the `Query()` function as a reference to the last connected database. E.g.
 
-	Query()->get('table_name');
+```php
+Query()->get('table_name');
+```
 
 or
 
-	$result = Query()->query($sql);

 If the `alias` key is set in the parameters, you can refer to a specific database connection

-	$params['alias'] = 'old';
+// Set the alias in the connection parameters

 ### Running Queries
 Query uses the same interface as CodeIgniter's [Active Record class](http://ellislab.com/codeigniter/user-guide/database/active_record.html). However, it does not implement the `update_batch` or caching methods.

-		->where('foo !=', 'bar')
+	->set('foobar', 'baz')
-		->update('table');

+```
 
 The `set` method can also take an array as a paramater, instead of setting individual values.
