分页Laravel的每日统计资料

Question

I have a RAW query in Laravel

$sales = DB::table('orders')
             ->select(DB::raw('DATE(created_at) as date'), 
                      DB::raw('SUM(total_price) AS total_price'), 
                      'created_at')
             ->groupBy('date')
             ->orderBy('date', 'DESC')
             ->paginate(20);

I am trying to paginate the result set, but it shows me the following error;

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'date' in 'group statement' 
(SQL: select count(*) as aggregate from `orders` group by `date`)

The above query works fine and returns me the complete result set when I replace;

paginate(20) with get()

What is going on?

Answer 1

$sales = DB::table('orders')
             ->select(DB::raw('DATE(created_at) as `date`'), 
                      DB::raw('SUM(total_price) AS total_price'), 
                      'created_at')
             ->groupBy('date')
             ->orderBy('date', 'DESC')
             ->paginate(20);

Try this code, it should work.
