mysql 左表连接右表查询，当右表关联数据没有，查询所有左表结果怎么显示

Question

项目表+订单表，需要查询所有项目的订单总额,现在订单表没有status=1的数据的话，查询结果就不显示所有项目

Project::leftjoin('orders','orders.project_id','=','project.id')
->where('project.status',1)
->where('orders.status',1)
->selectRaw('project.id,project.name,sum(orders.total) as total_money')
->groupBy('project.id')
->orderByDesc('total_money')
->paginate(10);

Answer 1

Project::leftjoin('orders', function($join) {
        $join->on('orders.project_id','=','project.id');
        $join->where('orders.status', 1);
    })
    ->where('project.status',1)
    ->selectRaw('project.id,project.name,sum(orders.total) as total_money')
    ->groupBy('project.id')
    ->orderByDesc('total_money')
    ->paginate(10);
