帮小弟我看一段CI代码

帮我看一段CI代码
$this->db->like('caller_ip',$condition);

$this->db->select('caller_ip, send_ip,star_time,end_time');

$query = $this->db->get('voice');

return $query->result_array();

模糊这样写对么？不对改怎么改？

------解决方案--------------------
隐隐约约冒失有个get_where方法。是吗
class PitypeModel extends Model {
$query = array();
$query = $this->db->get_where(‘table_name’, array('recodname' => $pitypetype));
$query->result();
