CodeIgniter - 將常規查詢更改爲活動記錄查詢

Question

我想知道是否有人能告訴我如何將以下sql查詢更改爲codeigniters活動記錄結構？

$query = $this->db->query('SELECT * FROM '.$this->table_name.' WHERE firstname LIKE "%'.$searchterm.'%" OR lastname LIKE "%'.$searchterm.'%"'); 
return $query->result(); 

乾杯

Answer 1

嘗試：

$this->db->like('firstname', $searchterm); 
$this->db->or_like('lastname', $searchterm); 
$query = $this->db->get($this->table_name); 

return $query->result(); 

Answer 2

$query = $this->db->get($this->table_name)->like('firstname', $searchterm)->or_like('lastname', $searchterm);
