$rahul = Buffalomilkrecord::select(DB::raw('date'), DB::raw('sum(totalmilk) as totalmilk, DATE_FORMAT(date,"%d") as "daykey"')) 
                                        ->whereBetween('date', [$olddate, $todaydate] )
                                        ->groupBy(DB::raw('date'))
                                        ->orderBy('date','asc')
                                        ->get();

                                        foreach($rahul as $order)
                                            {
                                                $ddtest[$order->daykey-1] = $order->date;
                                            }

Here i am expecting to start array with 0 => "2022-02-08" and so on.... as date start in Month and end with March

I feel i am doing some error in query but can not find where i am doing mistake.. Thanks in advance for help

CodePudding user response：

The SQL will only return exiting data, so if there is no data for this specific day, you wont get a row for this day. This is something you have to take care outside of the query.

You need to build the date range by yourself. for example like this: I have 2 dates in PHP, how can I run a foreach loop to go through all of those days?

Build one array with "default" entries per day with 0 values and than merge them with the sql result.
