let's try this

DB::table('table')
    ->select('column1', 'column2', 'column3')
    ->get();

You are using whereBetween incorrectly. The first parameter should be the column name.

It would be better to just use two "where" clauses. You should put:

$waktu = explode(" ", $datetime);
$rs = DB::table('otc_shift')
    ->select('shift_id')
    ->whereNull('deleted_at')
    ->where('shift_time_start','<',$waktu[1])
    ->where('shift_time_end','>',$waktu[1])
    ->first();
return $rs->shift_id;

@Pardeeptech this olution not for my case @abinadi result is null

Iwan to shot this result my query to implemented on Laravel.

Perfecto.. @tezlopchan with this code:

->whereRaw("'$waktu[1]' BETWEEN shift_time_start AND shift_time_end")

But if i have $waktu[1] = '23:00:00' result is null..
