Eloquent 2 left join query - sql

Question

I would like to execute the following query using Laravel's eloquent query builder:
SELECT a.*, b.day, c.sex FROM hours as a
left join reserves as b
on a.id = b.hour_id and b.day = '2015-12-12'
left join doctors as c
on a.doctor_id = c.id
where a.doctor_id = 1;
I have tried the following:
Hour::leftJoin('reserves', function($join) {
$join->on('hours.id' , '=' , 'reserves.hour_id')
->where('reserves.day' , '=' , '2015-12-12');
})
->leftJoin('doctors', function($join) {
$join->on('hours.doctor_id', '=', 'doctors.id');
})
->where('hours.doctor_id', '=', $doctorId)
->get();
Unfortunately, I am not getting the same results.

Answer 1

Everything looks fine, however you miss selecting columns, after Hour:: you should add:
select('hours.*'.'reserves.day','doctors.sex')->
You could also make second join simpler and use aliases, so the final code could look like this:
Hour::select('hours.*'.'reserves.day','doctors.sex')
->from('hours AS a')
->leftJoin('reserves AS b', function($join) {
$join->on('a.id' , '=' , 'b.hour_id')
->where('b.day' , '2015-12-12');
})
->leftJoin('doctors AS c', 'a.doctor_id', '=', 'c.id')
->where('a.doctor_id', $doctorId)
->get();
Of course as $doctorId you should set 1 to get exact same result

Answer 2

you can use DB::raw :
Hour::select(DB::raw('hours.*'),reserves.day, c.doctors)
->leftJoin('reserves',DB::raw("hours.id = reserves.hour_id AND reserves.day='2015-12-12'") ,DB::raw(''), DB::raw(''))
->leftJoin('doctors','hours.doctor_id', '=', 'doctors.id')
->where('hours.doctor_id', '=', $doctorId)
->get()
the 2 empty DB::raw is because leftJoin expect 4 arguments(table,columnA,operator,columnB)
