Laravel在一个查询中进行不同选择

Question

I will try to describe my situation; I have two separate queries below:

   public function getDriversCount($request) {
      return Driver::count();
   }

and the second one:

public function getDriversCountWithStatus($request) {
    return Driver::select('status', DB::raw('count(*) as total'))
                        ->groupBy('status')
                        ->get();
}

now we can see that these two are two separate functions and to separate queries. In the first one I am counting the whole drivers table records, but in the second one I am counting according to status groups. So how can I achieve the same result by one function and one query? something like that:

{
    "absolute_total": 21,
    "with_status": [
        {
            "status": 0,
            "total": 11
        },
        {
            "status": 1,
            "total": 10
        }
    ]
}

this one I received manually by calling these two functions separately.

Answer 1

You can do the below, we set an empty array at the start, so if the function returns an empty array you can do further checking on that:

public function getDriversCountAndStatus($request)
{
    // Set the array that will be returned
    $driversCountWithStatus = [];

    // Get the driver count
    $driverCount = Driver::count();

    // Get the driver status
    $driverStatus = Driver::select('status', DB::raw('count(*) as total'))
                    ->groupBy('status')
                    ->get();

    // Combine the driver count and status into one array
    $driversCountWithStatus = [
        "absolute_total" => $driverCount,
        "with_status" => $driverStatus;
    ];

    return $driversCountWithStatus;
}

I can't comment yet because I don't have enough rep.

I think I understand what you mean. The easiest way to do this would be chaining a couple of selects together.

Something like

public function getDriversCountWithStatus($request) {
    return Driver::select('total', DB::raw('count(*) as total'))
        ->addSelect('status', DB::raw('count(*) as total group by status'))
        ->get();
}
