I have this SQL query and It looks confusing enough for me to think how I will convert this to a Codeigniter Active Record query.
I considered looping through it getting by line like this:
for ( $i=1 ; $i<=5 ; $i++) {
${'line'.$i} = $this->staffrequisition_model->getRequestsToProcess($i,$staffInfo->position_depth,$staffInfo->department_group);
}
$data = array_merge($line1, $line2, $line3, $line4, $line5);
Using this method in my model
public function getRequestsToProcess($i,$depth,$departmentGroup)
{
$this->db->select('*, ns_request_info.idx as request_idx, ns_staff_info.idx as staff_idx');
$this->db->from('ns_request_info');
$this->db->join('ns_staff_info', 'ns_request_info.requested_by_idx = ns_staff_info.member_idx');
$this->db->where('line'.$i.'', $depth);
$this->db->where('line'.$i.'_action', 'PENDING');
if($departmentGroup!='HIGHER TIER'){ $this->db->where('ns_staff_info.department_group', $departmentGroup); }
$this->db->where('status', 'PENDING');
$this->db->or_where('status', 'ONGOING');
$this->db->where('line'.$i.'', $depth);
$this->db->where('line'.$i.'_action', 'PENDING');
if($departmentGroup!='HIGHER TIER'){ $this->db->where('ns_staff_info.department_group', $departmentGroup); }
$this->db->order_by('idx', 'desc');
$query = $this->db->get();
return $query->result_array();
}
But I realized that doing array merge for all of them would destroy the sorting of the id's of the result.
I have here my SQL query and I have no idea on how to transform this into a Codeigniter Active Record query.
SELECT *, ns_request_info.idx as request_idx, ns_staff_info.idx as staff_idx
FROM `ns_request_info`
INNER JOIN `ns_staff_info`
ON ns_request_info.requested_by_idx = ns_staff_info.member_idx
WHERE (
(ns_request_info.line1=1 AND ns_request_info.line1_action='PENDING') OR
(ns_request_info.line2=1 AND ns_request_info.line2_action='PENDING') OR
(ns_request_info.line3=1 AND ns_request_info.line3_action='PENDING') OR
(ns_request_info.line4=1 AND ns_request_info.line4_action='PENDING') OR
(ns_request_info.line5=1 AND ns_request_info.line5_action='PENDING')
) AND (ns_request_info.status='PENDING' OR ns_request_info.status='ONGOING')
ORDER BY ns_request_info.idx DESC
I hope you guys can help me out.
Try something like this:
$search_val = 1;
$action = "PENDING";
$this->db->where("nri.line1 = $search_val and nri.line1_action = '{$this->db->escape_str($action)}'")
->or_where("nri.line2 = $search_val and nri.line2_action = '{$this->db->escape_str($action)}'")
->or_where("nri.line3 = $search_val and nri.line3_action = '{$this->db->escape_str($action)}'")
->or_where("nri.line4 = $search_val and nri.line4_action = '{$this->db->escape_str($action)}'")
->or_where("nri.line5 = $search_val and nri.line5_action = '{$this->db->escape_str($action)}'")
->join('ns_staff_info nsi', 'nsi.member_idx = nri.requested_by_idx')
->get('ns_request_info nri')->result_array();
public function getRequestsToProcess($depth,$departmentGroup)
{
$this->db->select('*, ns_request_info.idx as request_idx, ns_staff_info.idx as staff_idx');
$this->db->from('ns_request_info');
$this->db->join('ns_staff_info', 'ns_request_info.requested_by_idx = ns_staff_info.member_idx');
$this->db->where("((ns_request_info.line1=".$depth." AND ns_request_info.line1_action='PENDING') OR (ns_request_info.line2=".$depth." AND ns_request_info.line2_action='PENDING') OR (ns_request_info.line3=".$depth." AND ns_request_info.line3_action='PENDING') OR (ns_request_info.line4=".$depth." AND ns_request_info.line4_action='PENDING') OR (ns_request_info.line5=".$depth." AND ns_request_info.line5_action='PENDING'))");
$this->db->where("(ns_request_info.status='PENDING' OR ns_request_info.status='ONGOING')");
if($departmentGroup!='HIGHER TIER'){ $this->db->where('ns_staff_info.department_group', $departmentGroup); }
$this->db->order_by('ns_request_info.idx', 'desc');
$query = $this->db->get();
return $query->result();
