Codeigniter括括號的語句

Question

我要做的是將where語句設置爲括號。事情是這樣的：

SELECT 
    `a_id` 
FROM 
    `auctions` 
WHERE 
    `a_state` = 1 
AND (
    `p_name` LIKE '%XXX%' 
    OR `at_name` LIKE '%XXX%' 
    OR `p_code` LIKE '%XXX%' 
) 

但我不想與

$this->db->query('SELECT `a_id` FROM `auctions` WHERE `a_state` =1 AND (`p_name` LIKE '%XXX%' OR `at_name` LIKE '%XXX%' OR `p_code` LIKE '%XXX%'); 

我想使用的活動記錄類來做到這一點。

有什麼想法？

感謝

Answer 1

$where="`a_state` =1 AND (`p_name` LIKE '%XXX%' OR `at_name` LIKE '%XXX%' OR `p_code` LIKE '%XXX%')"; 

    $this->db->select('a_id'); 
    $this->db->where($where); 
    $this->db->from('auctions'); 
    $query = $this->db->get(''); 
echo $this->db->last_query();// print the last query
