嵌套Codeignitor活動記錄「選取」

Question

我不知道是否有在活動記錄的任何方式來創建像嵌套WHERE案件查詢：

SELECT * FROM Users WHERE FirstName = 'John' AND (LastName = 'Smith' OR LastName = 'Jones'); 

任何意見或建議，將不勝感激。

Answer 1

是的，你可以使用where()功能

$this->db->select('*'); 
$this->db->from('Users '); 
$this->db->where("FirstName = 'John'"); 
$this->db->where(" (LastName = 'Smith' OR LastName = 'Jones') "); 
$result=$this->db->get(); 

Active Record

Answer 2

您需要通過在WHERE子句中爲了做到這一點。

$this->db->where("FirstName = 'John' AND (LastName = 'Smith' OR LastName = 'Jones')");
