Any short way for handling multiple queries in laravel? - laravel

Question

I need to get multiple results from different queries on one table.
For example I need to get Count, Sum, Average of one table. Should I do like this or is there a shorter way?
public function index()
{
$count = Patient::all()->count();
$dateCount = Patient::where('date', date("Y-m-d"))->count();
$loanAmount = DB::table('patients')->sum('loan_amount');
$payAmount = DB::table('patients')->sum('pay_amount');
return view('index', compact('count','dateCount','loanAmount' ,'payAmount'));
}
If you see All queries are for one table to get specific results, So basically is there a short way to get these results not by single queries for each?

Answer 1

You can do this by DB query as below :
$data=\DB::table('patients')
->selectRaw('count(id) as count,sum(loan_amount) as loanAmount,sum(pay_amount) as payAmount,sum(case when date = "'.date("Y-m-d").'" then 1 else 0 end) AS dateCount')
->first();
You can also do this using eloquent but it will return you collection.
$data=Patient::selectRaw('count(id) as count,sum(loan_amount) as loanAmount,sum(pay_amount) as payAmount,sum(case when date = "'.date("Y-m-d").'" then 1 else 0 end) AS dateCount')
->first();

Answer 2

You can do something like this.
public function index()
{
$patient = Patient::all();
$count = $patient->count();
$dateCount = Patient::today()->count();
$loanAmount = $patient->sum('loan_amount');
$payAmount = $patient->sum('pay_amount');
return view('index', compact('count','dateCount','loanAmount' ,'payAmount'));
}
Also you can create scope in your patient model:
public function scopeToday($query) {
return $query->where('date', date("Y-m-d"));
}
