Hello, there is an original dataset with 4 collections as shown above. I was try to transform the data with group by agent_id and sum of the amount .

I was plan to using sub query likes select agent_id, sum(amount) from (Dataset) group by agent_id , however I have no idea how to achieve it in laravel sub query. Can anyone guide me or and provide some suggestion. Appreciate it.

If the data is provided via a dataset or an api call then you can use Laravel Collection methods to manipulate and get the desired output

//Assuming that the data is in array format
$output = collect($data)
  ->groupBy('agent_id')
  ->map(
    fn($records, $agent) => ['agent_id' => $agent, 'amount' => $records->sum('amount')]
  )
  ->values()->all();
