Deleting selected records

@Wouter60, So I put it in an online regex tester and it worked properly catching only first-char lower case alphas. Now I need to debug the surrounding code to see where I screwed up. This is my model function BTW:

<MyCode>
public function libraryClean() {

$this->db->select('*');
$this->db->where('title REGEXP "^[a-z]" ', NULL, FALSE);
$list=$this->db->get('mz');
return $list->num_rows();
}
</MyCode>

Thanks for the help.
