Need eloquent/fluent query to get sum with groupBy function.
So far I have tried:
$this->data['no_of_pages'] = Document::sum('no_of_pages')
->groupBy('users_editor_id');
Which ofcourse gives me call to member function groupBy() on non-object because of the fact that sum() will already execute the query and have result ready by the time grouBy() is applied. So can anyone guide me?
Document::groupBy('users_editor_id')
->selectRaw('sum(no_of_pages) as sum, users_editor_id')
->pluck('sum','users_editor_id');
// originally lists(), which was deprecated in favour of pluck in 5.2
// and dropped completely in 5.3
// ->lists('sum','users_editor_id');
// returns array like this:
array(
users_editor_id => sum,
...
)
Or this way (which I wouldn't use, since it won't be actual ORM result):
Document::groupBy('users_editor_id')
->selectRaw('*, sum(no_of_pages) as sum')
->get();
// returns collection of Document pseudo models with additional sum field
Document::Where('some_condition',true)
->select([DB::raw("SUM(debit) as total_debit"), DB::raw("SUM(credit) as total_credit")])
->groupBy('id')
->get()
Little bit refactored and convenient answer is (from @keroles Monsef)
Document::Where('some_condition',true)
->selectRaw("SUM(debit) as total_debit")
->selectRaw("SUM(credit) as total_credit")
->groupBy('id')
->get();
selectRaw("SUM(credit) + SUM(debit) as total_amount")
