Help with CI active record and like statement

[eluser]CroNiX[/eluser]
Using active record, is it possible to generate a like statement like this (using 'LOWER' in the where)? Or should I just query using my own sql statement?

SELECT name FROM users WHERE LOWER(name) LIKE '$some_var%';

Ive been doing:

Code:

return $this->db->select('name')
                ->like('name', $search_name, 'after')
                ->get('users')
                ->result_array();

Thanks,
CroNiX
