Question

我尝试使用Model :: with

添加附加列

$pitchChech =  Pitch::with(['prices'=>function ($query){
            $query->select('*',\DB::Raw("(select sum(HOUR(TIMEDIFF(valid_to ,valid_from))) from pitch_price as xpitch_price where pitch_id = pitch_price.pitch_id ) as x "))
            ->whereRaw(" x < ?",[24]);
        }])->get();
      dd($pitchChech);

我有这个输出

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'x' in 'where clause'

我无法理解使用laravel 5.1是什么问题，但是我不认为ut会有问题

Answer 1

对于派生列，您必须使用having()：

->having('x', '<', 24)

带有模型::带有附加列的Laravel Prolem
