Laravel 4 普通查询中的laravel查询生成器

这是普通查询。是否更改为laravel查询？。 我试过了

我无法比较

->where（'sum（payment\u transactions.amount）'，！='，DB:：raw（'bill\u det.amount\u payment'））

我使用的是这样的

->whereRaw（'bill\u det.amount\u paid！=sum（payment\u transactions.amount）

{“error”：{“type”：“illumb\Database\QueryException”，“message”：“SQLSTATE[HY000]：一般错误：1111将组函数（SQL:select count（*）用作来自（选择“1”作为行计数，从

bill\u det

left join

payment\u transactions

on

bill\u det

=

payment\u transactions

中选择

payment\u transactions

状态=成功和bill\u det.amount\u支付！=金额（payment\u transactions.amount）分组依据

bill\u det

bill\u no

订单依据

bill\u det

bill\u no

desc）计数行表）

将此转换为laravel查询后：：

DB::select(DB::raw( 'SELECT a.bill_no, a.account_id, a.bill_date, a.amount_paid,
                            b.transaction_code,b.amount from  bill_det a left join
                            (select bill_no, transaction_code, sum(amount) as amount from payment_transactions 
                            where status = "success" group by bill_no ) b
                            on a.bill_no = b.bill_no where a.amount_paid != b.amount order by b.bill_no'));

你试过什么了吗？我试过了。问题是我无法比较需要使用whereRaw来比较sum（）结果的总和。我使用whereRaw，但它给出了如上所述的错误。我认为你应该使用“having”语句而不是“where”语句

$bill=DB::table('bill_det')->leftJoin('payment_transactions', 'bill_det.bill_no', '=', 'payment_transactions.bill_no')
                                ->select('bill_det.bill_no','bill_det.account_id','bill_det.bill_date','bill_det.amount_paid',
                                'payment_transactions.transaction_code',DB::raw('sum(payment_transactions.amount) as amount'))
                                ->where('payment_transactions.status','=','success')
                                ->where('sum(payment_transactions.amount)','!=',DB::raw('bill_det.amount_paid'))
                                ->groupBy('bill_det.bill_no')
                                ->orderBy('bill_det.bill_no','desc');

DB::select(DB::raw( 'SELECT a.bill_no, a.account_id, a.bill_date, a.amount_paid,
                            b.transaction_code,b.amount from  bill_det a left join
                            (select bill_no, transaction_code, sum(amount) as amount from payment_transactions 
                            where status = "success" group by bill_no ) b
                            on a.bill_no = b.bill_no where a.amount_paid != b.amount order by b.bill_no'));

$query = \Illuminate\Support\Facades\DB::table('bill_det')
            ->select('a.bill_no', 'a.account_id', 'a.bill_date', 'a.amount_paid', 'b.transaction_code', 'b.amount')
            ->leftJoin(DB::raw('(select bill_no, transaction_code, sum(amount) as amount from payment_transactions 
                            where status = "success" group by bill_no) b'), function($join) {
                $join->on('a.bill_no', '=', 'b.bill_no');
            })
            ->where('a.amount_paid','<>', 'b.amount')
             ->orderBy('b.bill_no')
            ->get();

$query->whereRaw(DB::raw('(your expression!!)'));
