php - 带有嵌套 "SELECT WHERE"的 Codeigniter Active Record

Question

我想知道在 Active Record 中是否有任何方法可以使用嵌套的 WHERE 案例创建查询，例如:

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

Answer 1

是的，你可以使用where()函数

$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
