我试图通过group_by
从数据库中提取数据名称经销商ID经销商数量
詹姆斯001 5
Thomas 002 7
比利005 4
詹姆斯001 6
托马斯002 9
我想要Out out
詹姆斯= 11
托马斯= 16
比利= 4
这是我的控制器
$data=array('reseller' =>$this->hasil_m->view_hasil(),
'isi' =>'admin/hasil'
);
$this->load->view('dashboard/wrapper',$data);
我的模特
function view_hasil() {
$this->db->select('*');
$this->db->from('tb_produk as pro');
$this->db->join('tb_reseller as res', 'pro.reseller_produk = res.nomor_reseller');
$this->db->join('tb_pelanggan as pel', 'pro.id_barcode = pel.id_barcode');
$this->db->group_by('res.nomor_reseller');
$ambil = $this->db->get('');
if ($ambil->num_rows() > 0) {
foreach ($ambil->result() as $data) {
$hasil[] = $data;
}
return $hasil;
}
}

您需要先将其相加,然后按此字段Procfile
Name Reseller
ID reseller
或者,如果你想要,你可以 $this->db->select('nama_reseller,ID_Reseller,sum (Quantity) as qty');
///
///
///
$this->db->group_by(array('Name_Reseller','ID_reseller'));
以简单的方式
->query()

在您的选择中使用SUM(Quantity)
。见下面的代码
function view_hasil()
{
$this->db->select('SUM(pro.Quantity) as Qty,YOUR_OTHER_FIELDS');
$this->db->from('tb_produk as pro');
$this->db->join('tb_reseller as res', 'pro.reseller_produk = res.nomor_reseller');
$this->db->join('tb_pelanggan as pel', 'pro.id_barcode = pel.id_barcode');
$this->db->group_by(['res.nomor_reseller','pro.ID_reseller']);
$ambil = $this->db->get();
if ($ambil->num_rows() > 0) {
//no need to looping it again $ambil->result() this is also an array
return $ambil->result();
}
}

尝试选择如下:
$this->db->select('SUM(pro.jumlah) as totalQuantity, pro.*');
