Codeigniter中的多列where_in子句

Question

下面是codeigniter單列where_in子句$this->db->where_in('x1',$val);

我如何在CodeIgniter where_in子句中傳遞多個列，例如下面的MySQL查詢， select * from tab1 where (col1,col2) in ((1,2),(2,3))

Answer 1

假設您的數據數組是這樣的（應該是）

$val1 = array(1,2);
$val2 = array(2,3);

和查詢應該是

$this->db->select('*');
$this->db->from('tab1');
$this->db->where_in('col1',$val1);
$this->db->or_where_in('col2',$val2);
$query = $this->db->get();
$result = $query->result_array();

---

否則你可以使用

$this->db->query("select * from tab1 where (col1,col2) in ($val1,$val2)");

Answer 2

“ $ arr_1 = some_array;”

“ $ arr_2 =某個數組；”

如果它們是相同的數組，只需將$array_2替換$array_2 $arr_1

$result = $this->db->select('*')->where_in('col1',$arr_1)->where_in('col2',$arr_2)->get('tab1')->result_array();

要么

$result = $this->db->select('*')->where_in('col1',$arr_1)->or_where_in('col2',$arr_2)->get('tab1')->result_array();
