我有以下sql查询

SELECT * FROM exams WHERE exams.id NOT IN (SELECT examId FROM testresults)

如何将其转换为Laravel查询构建器格式？

谢谢.

我在系统中使用数据库作为队列驱动程序。如何删除存储在作业表中的排队作业？

谢谢

以下是使用Laravel查询构建器的查询:

$begin = new DateTime('2016-07-01');
$end = new DateTime('2016-07-31');
$startDate = $begin->format('Y-m-d 00:00:00');
$endDate = $end->format('Y-m-d 23:59:59');
$deposit = $depositModel->select(DB::raw('user_deposit.user_id as user_id, sum(user_deposit.amount) as total_deposit, null as total_withdraw'))
                        ->whereBetween('date_time', [$startDate, $endDate])
                        ->where('user_deposit.status', 1)
                        ->groupBy('user_deposit.user_id');
$withdraw = $withdrawModel->select(DB::raw('user_withdraw.user_id as user_id, null as total_deposit, sum(user_withdraw.amount) as total_withdraw'))
                        ->whereBetween('user_withdraw.created_at', [$startDate, $endDate])
                        ->where('user_withdraw.status', 1)
                        ->groupBy('user_withdraw.user_id');
$deposit = $deposit->unionAll($withdraw);
$transaction = DB::table(DB::raw("({$deposit->toSql()}) t"))
                  ->select('user_id', DB::raw("sum(total_deposit) as total_deposit_amount, sum(total_withdraw) as total_withdraw_amount"))
                  ->groupBy('user_id')
                  ->get();

我希望得到如下结果:

"transaction": [
            {
                "user_id": 2,
                "total_deposit_amount": "101.00",
                "total_withdraw_amount": "50.50"
            },
            {
                "user_id": …

for (var i = 0; i < rows.length; i++) {   
      $('#rows').after('<tr>
                           <td>'+ i + 1 + '</td>'
                           <td>'+rows[i][\'title\']+'</td>
                           <td>'+rows[i][\'startTime\']+' 
                        </tr>'); 
}

在上面的jquery代码中,我想在我的html中使用"rows"类在div之后插入表行.但是,我收到了错误

Uncaught SyntaxError: Unexpected token ILLEGAL

我可以知道什么是错的,我该如何解决？谢谢

如何在 Laravel 中执行多个其中操作？

$devices = DB::table('foo')
              ->select('foo.*')
              ->whereIn('bar1', $request->bar1)
              ->whereIn('bar2', $request->bar2)
              ->get();

上面是我的示例代码，但它返回一个空数组。
