在laravel框架中使用SUM在whereraw/where中的应用

Question

我有名为PlanCost Discount AmountPaid的列和包含Due的标签。

在这里，我试图只显示PlanCost != AmountPaid所在的行

这是我的全部查询

 $getID = isset($inputArray['id']) ? $inputArray['id'] : 0;
    $query = TelePlanSelect::join('tele_plan', 'tele_plan.id', '=', 'tele_plan_select.teleplan_id'  )
        ->leftjoin('tele_payment_defs', 'tele_payment_defs.telereg_id', '=', 'tele_plan_select.telereg_id')
        ->leftjoin('tele_payment_items', function ($join){
            $join->on('tele_payment_items.telepaymentdefs_id', '=', 'tele_payment_defs.id')
                ->on('tele_payment_items.teleplan_id', '=' ,'tele_plan.id');
        } )

        ->selectRaw('tele_plan.id as `PlanID`,' .
            'tele_plan.plan_name as `PlanName`,' .
            'tele_plan.plan_cost as `PlanCost`,' .
            'tele_plan.plan_details as `PlanDetails`,'.
            'sum(tele_payment_items.amount) as  `AmountPaid` ,'.
            'COALESCE(sum(tele_payment_items.discount),0) as `Discount`,'.
            '(COALESCE(tele_plan.plan_cost,0) -  sum(COALESCE(tele_payment_items.discount,0))) - sum(coalesce(tele_payment_items.amount, 0)) as  `Due` '

        )
        ->where('tele_plan_select.telereg_id', $getID)
        ->groupBy('tele_plan.id')
      ->where(' tele_plan.plan_cost', '!=', 'sum(tele_payment_items.amount)');

我不确定我们是否可以在sum中使用where/whereraw，有人能帮我吗？

您可以使用像sum这样的原始sql函数，但是必须将它们封装在laravel的\DB::raw()函数中，这样才不会转义。

对于Where子句，应该执行以下操作

->where('tele_plan.plan_cost', '<>', \DB::raw('sum(tele_payment_items.amount)'));

您还可以使用laravel的WhereRaw函数来编写自己的条件：

->whereRaw('tele_plan.plan_cost <> sum(tele_payment_items.amount)')

更新：错误声明GroupBy有问题。这样做的原因是，只有在组之后才能完成和，而其中不能这样做。因此，必须将其添加到HAVING clause中。

将where替换为where，这应该有效：

->havingRaw('tele_plan.plan_cost <> sum(tele_payment_items.amount)');
