At a time am inserting 4 records with id 1,2,3,4 and it should be next sequence number should be 5.How to set this?
$this->db->select('NEXT VALUE FOR job_seq as jobid');
$queryjobid = $this->db->get();
foreach ($queryjobid->result_array() as $row) {
$job_Id = $row['jobid'];
}
if (is_array($this->input->post('getschedule'))) {
foreach($this->input->post('getschedule') as $value) {
//Auto generate JOB SCHEDULE HERE
$this->db->insert('job_schedule', array(
'jobschedule_id' => $jobschedule_id,
'Activity_area_id' => $Activity_area_id,
'Contract_id' => $this->input->post('getcontract_id'),
'job_freq_id' => $this->input->post('getcontractbranch_freq'),
'job_schedule_dates' => $value[0], //assume array form like your screenshot
'job_schedule_frequency' => $value[1],
'created_at' =>$created_Dt
));
//Auto generate JOB HERE
$incjobid = $job_Id++;
$this->db->insert('job', array(
'Job_id' => $incjobid,
'Job_no' => $incjobid,
'Contract_id' => $this->input->post('getcontract_id'),
'Job_Date' => $value[0],
