在 where 条件下使用数组

Question

I have an array data called $req_dep . Here's what it look like when I var_dump() it.

array(2) { [0]=> int(41) [1]=> int(765) }

I want to use that data in query

  select * from dbo.RequisitionTable 
  where RequestorID = '$ID'
  and RequestorDepartmentID in ($req_dep)
  and IsProcessedToHire=0 
  and IsHold = 0
  and IsRejected = 0

But it always get error "Array to string conversion" . How to use array in where condition like that?

Thank You

Answer 1

Your query:

select * from dbo.RequisitionTable 
where RequestorID = '$ID'
and RequestorDepartmentID in ($req_dep)
and IsProcessedToHire=0 
and IsHold = 0
and IsRejected = 0

Can easily be converted to CodeIgniter's query builder like this:

$this->db->select('*');
$this->db->from('dbo.RequisitionTable');
$this->db->where('RequestorID', $ID);
$this->db->where_in('RequestorDepartmentID', $req_dep);
$this->db->where('IsProcessedToHire', 0);
$this->db->where('IsHold', 0);
$this->db->where('IsRejected', 0);

The above assumes $ID and $req_dep are passed to the model and that the latter is an array

Answer 2

Why don't you use Query builder class ? You can do that by,

$conds = [
   "RequestorID" => $ID,
   "IsProcessedToHire" => 0,
   "IsHold" => 0,
   "IsRejected" => 0  
];

$result = $this->db->where($conds)->where_in("RequestorDepartmentID", $req_dep)->get("RequisitionTable")->result_array();
