在codeigniter中使用聚合函数更新列

Question

我想将此格式更改为codeigniter格式，即

this->db->where('','')

这是我的代码

$data = "UPDATE dbhpl.hplpb SET hplpb.PEL_4 = (select COUNT(*) FROM pelayanan 
WHERE pelayanan.ID_AREA=hplpb.ID_AREA AND pelayanan.ID_VERIFIKASI='4' 
AND pelayanan.TRANSAKSI='PENYAMBUNGAN BARU' AND pelayanan.ESTIMASI='4' 
AND pelayanan.ID_STATUS='1')";
$this->db->query($data);

我怎样才能改变它?

Answer 1

你可能想试试这个

$data = array(
        'ID_VERIFIKASI' => '4',
        'TRANSAKSI' => 'PENYAMBUNGAN BARU',
        'ESTIMASI' => '4',
        'ID_STATUS' => '1'
);
$this->db->where($data)
         ->from('pelayanan')
         ->join('hplpb', 'hplpb.ID_AREA = pelayanan.ID_AREA', 'inner');
$count = $this->db->count_all_results();

$data = array(
    "PEL_4" => $count
);
$this->db->update('hplpb', $data);
