我试图创建一个报告页面，显示从特定日期到特定日期的报告。这是我当前的代码:
$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', $now)->get();
这在普通SQL中所做的是从表中选择*，其中reservation_from = $now。
我在这里有这个问题，但我不知道如何将其转换为雄辩的问题。
SELECT * FROM table WHERE reservation_from BETWEEN '$from' AND '$to
如何将上面的代码转换为雄辩的查询?
当前回答
以下方法应该有效:
$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', '>=', $now)
->where('reservation_from', '<=', $to)
->get();
其他回答
你可以使用DB::raw(")使列作为日期MySQL使用whereBetween函数如下:
Reservation::whereBetween(DB::raw('DATE(`reservation_from`)'),
[$request->from,$request->to])->get();
如果你的字段是datetime而不是date(尽管它适用于这两种情况):
$fromDate = "2016-10-01";
$toDate = "2016-10-31";
$reservations = Reservation::whereRaw(
"(reservation_from >= ? AND reservation_from <= ?)",
[
$fromDate ." 00:00:00",
$toDate ." 23:59:59"
]
)->get();
试试这个:
因为你是基于单列值进行抓取，你可以同样简化你的查询:
$reservations = Reservation::whereBetween('reservation_from', array($from, $to))->get();
根据条件检索:laravel文档
希望这对你有所帮助。
如果你需要在何时有一个datetime字段应该像这样。
return $this->getModel()->whereBetween('created_at', [$dateStart." 00:00:00",$dateEnd." 23:59:59"])->get();
我已经创建了模型作用域
要了解更多关于范围的信息，请查看以下链接:
laravel.com/docs/eloquent # query-scopes medium.com/@janaksan / using-scope-with-laravel
代码:
/**
* Scope a query to only include the last n days records
*
* @param \Illuminate\Database\Eloquent\Builder $query
* @return \Illuminate\Database\Eloquent\Builder
*/
public function scopeWhereDateBetween($query,$fieldName,$fromDate,$todate)
{
return $query->whereDate($fieldName,'>=',$fromDate)->whereDate($fieldName,'<=',$todate);
}
在控制器中，将Carbon Library添加到顶部
use Carbon\Carbon;
从现在开始获取最近十天的记录
$lastTenDaysRecord = ModelName::whereDateBetween('created_at',(new Carbon)->subDays(10)->startOfDay()->toDateString(),(new Carbon)->now()->endOfDay()->toDateString() )->get();
从现在开始获取过去30天的记录
$lastThirtyDaysRecord = ModelName::whereDateBetween('created_at',(new Carbon)->subDays(30)->startOfDay()->toDateString(),(new Carbon)->now()->endOfDay()->toDateString() )->get();
