Sum in laravel 数据库查询

Question

我需要在使用 join 时得到 ProductQTY groupBy ProductID 的总和，我在使用 [=12= 时总是出错], 附上我的代码

$pick_list_items = DB::table('pick_list_detail')
                   ->where('pick_list_detail.pick_list_id',$id)
                   ->join('sale_invoices', 'pick_list_detail.sale_invoice_id','=','sale_invoices.id')
                   ->join('sale_invoice_detail', 'sale_invoice_detail.sale_invoice_id','=','pick_list_detail.sale_invoice_id')
                   ->select(['pick_list_detail.sale_invoice_id', 'sale_invoice_detail.product_id', 'sale_invoice_detail.product_qty', 'sale_invoice_detail.uom', 'sale_invoice_detail.uom_factor'])
                   ->sum('sale_invoice_detail.product_qty')
                   ->groupBy('sale_invoice_detail.product_id')
                   ->get();

我正在使用 laravel 5.4

这里是错误

(2/2) QueryException SQLSTATE[42000]: Syntax error or access violation: 1055 'fdis.pick_list_detail.sale_invoice_id' isn't in GROUP BY (SQL: select pick_list_detail.sale_invoice_id, sale_invoice_detail.product_id, sale_invoice_detail.product_qty, sale_invoice_detail.uom, sale_invoice_detail.uom_factor from pick_list_detail inner join sale_invoices on pick_list_detail.sale_invoice_id = sale_invoices.id inner join sale_invoice_detail on sale_invoice_detail.sale_invoice_id = pick_list_detail.sale_invoice_id where pick_list_detail.pick_list_id = 1 group by sale_invoice_detail.product_id)

Answer 1

    $sale_invoices = DB::table('pick_list_detail')
    ->select(DB::raw('sum(sale_invoice_detail.product_qty) as si_count, pick_list_detail.pick_list_id , sale_invoice_detail.product_id , sale_invoice_detail.uom, sale_invoice_detail.uom_factor '))
    ->where('pick_list_detail.pick_list_id',$id)
    ->join('sale_invoices', 'pick_list_detail.sale_invoice_id','=','sale_invoices.id')
    ->join('sale_invoice_detail', 'sale_invoice_detail.sale_invoice_id','=','pick_list_detail.sale_invoice_id')
    ->groupBy('pick_list_detail.pick_list_id')
    ->groupBy('sale_invoice_detail.product_id')
    ->groupBy('sale_invoice_detail.uom')
    ->groupBy('sale_invoice_detail.uom_factor')
    ->get();
