按日期排序的退货数据
我有一个函数可以返回每天的销售计数。这种方法的问题是,我希望将数据按日期存储,但我让他们按以下顺序:按日期排序的退货数据
01-Dec 02-Dec
03-Dec
03-Nov
04-Nov
05-Nov
etc.
我明白为什么出现这种情况,但我不知道如何解决它。我可以用startofmonth代替subMonth(1),这会部分解决我的问题,但这不是我想要的。我反而希望返回订购的最后30天。
return DB::table('sales') ->select(\DB::RAW('DATE_FORMAT(created_at, "%d-%M") as date'), \DB::raw('COUNT(*) as count'))
->where('created_at', '>=', Carbon::now()->subMonth(1))
->orderBy('date')
->groupBy('date')
->get(['date', 'count'])
->keyBy('date')
->transform(function ($data) {
return $data->count;
});
我也试过orderBy('created_at'),但它给了我下面的错误,我想避免更改sql模式。
Syntax error or access violation: 1055 Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'x.sales.created_at' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
编辑: 按照要求,该return语句
select DATE_FORMAT(created_at, "%d-%M") as date, COUNT(*) as count from `sales` where `created_at` >= ? group by `date` order by `date` asc
回答:
的SQL查询我没有你的框架查询语法太多的想法。但是您可以在显示数据时再添加一列DATE_FORMAT(created_at,“%Y%m%d”)作为order_column并应用顺序,并按列“order_column”分组,并使用列“data”。
select DATE_FORMAT(created_at, "%Y%m%d") AS order_column, DATE_FORMAT(created_at, "%d-%M") as date, COUNT(*) as count from `sales` where `created_at` >= ? group by `order_column` order by `order_column` asc return DB::table('sales')
->select(\DB::RAW('DATE_FORMAT(created_at, "%Y%m%d") AS order_column'),\DB::RAW('DATE_FORMAT(created_at, "%d-%M") as date'), \DB::raw('COUNT(*) as count'))
->where('created_at', '>=', Carbon::now()->subMonth(1))
->orderBy('order_column')
->groupBy('order_column')
->get(['date', 'count'])
->keyBy('date')
->transform(function ($data) {
return $data->count;
});
回答:
如果你在2个步骤中做到这一点,它是否工作?
第一步,在其中创建日期列:
$step1 = DB::table('sales') ->select(\DB::RAW('DATE_FORMAT(created_at, "%d-%M") as date'))) ->where('created_at', '>=', Carbon::now()->subMonth(1))
->orderBy('date')
->get(['date', 'count'])
之后,你做agregation:
$step2 = $step1->select('date'), \DB::raw('COUNT(date) as count')) ->groupBy('date') ->get(['date', 'count']) ->keyBy('date')
希望它能帮助!
