noname :
I am a new Laravel learner and having difficulty to convert from sql
here is my sql
select sum(employee_income)
from employee
group by employee_id, employee_department
this query works when I test.
here is my simplified Laravel but it doesn't work.
DB::raw('(select sum(employee_income) from employee group by employee_id, employee_department)')
Can anybody see something wrong?
Tim Lewis :
You shouldn't use DB::raw() unless you have to. Laravel has the Eloquent Query Builder, which provides an easy to type, Database-agnostic (works with all DBs) method of writing queries. This one should be pretty simple:
$sum = Employee::groupBy('employee_id')
->groupBy('employee_department')
->sum('employee_income');
// Or, if you don't have an `Employee.php` model
$sum = DB::table('employees')
->groupBy('employee_id')
->groupBy('employee_department')
->sum('employee_income');
