Non-associative array in codeigniter

[eluser]Unknown[/eluser]
CodeIgniter always returns associative array from model.
suppose I want to get "name" from "user_master" table.So i have written the following query in model

$rows = $this->db->select('Name')
->from('user_master')->get()->result_array();
And the result is as follows:
Array
(
[0] => Array
(
[Name] => Sumanta
)
)
But I want the result as follows

Array(
[0]=>Sumanta
)

How I'll will get it?

See Jamie Rumbelow's 'MY_Model' class, he has a method that does exactly what you're describing.
