Laravel Eloquent 多重求和

Question

联系人表的列

Name=client_id
Name=room_id
Name=stats - a number
Name=date

我需要计算一年、每周、每月和每季度的统计数据，以及统计数据列的许多总和。我为旧系统创建了这个 SQL，现在我需要获取 stats 列的总和，而不是像以前那样计算它们。

SELECT 
  SUM(
    date > '2021-01-11 00:00:00' 
    AND date < '2021-01-18 00:00:00' 
    AND room_id = 6 
    AND client_id = 1
  ) as week1,
  SUM(
    date > '2021-12-20 00:00:00' 
    AND date < '2021-12-27 00:00:00' 
    AND room_id = 6 
    AND client_id = 1
  ) as week51, 
  SUM(
    date > '2021-01-01 00:00:00' 
    AND date < '2021-01-31 23:59:00' 
    AND room_id = 6 
    AND client_id = 1
  ) as month1, 
  SUM(
    date > '2021-12-01 00:00:00' 
    AND date < '2021-12-31 23:59:00' 
    AND room_id = 6 
    AND client_id = 1
  ) as month12 
FROM 
  contact;

是否可以使用 Eloquent 来实现，或者我需要使用 DB 外观？如果使用 Eloquent 是一种更简单的方法，我想使用它。

你可以这样做

$conditions  = [
  
    'week1' =>  [
    
        ['date' ,  '>' ,  '2021-01-11 00:00:00' ] ,     
        ['date' ,  '<' ,  '2021-01-18 00:00:00' ] ,     
        ['room_id' ,  6 ] ,     
        ['client_id' ,  1 ] ,     

    ] , 
    'month1' =>  [
    
        ['date' ,  '>' ,  '2021-12-01 00:00:00' ] ,     
        ['date' ,  '<' ,  '2021-01-31 23:59:00' ] ,     
        ['room_id' ,  6 ] ,     
        ['client_id' ,  1 ] ,     

    ] , 
  
  ];

  $output = [];
  foreach ($conditions as $k=>$condition )
      $output[$k] = Contact::where($condition)->sum('stats');

---------------- 使用联合 -----------------

$conditions  = [
  
    'week1' =>  [
    
        ['date' ,  '>' ,  '2021-01-11 00:00:00' ] ,     
        ['date' ,  '<' ,  '2021-01-18 00:00:00' ] ,     
        ['room_id' ,  6 ] ,     
        ['client_id' ,  1 ] ,     

    ] , 
    'month1' =>  [
    
        ['date' ,  '>' ,  '2021-12-01 00:00:00' ] ,     
        ['date' ,  '<' ,  '2021-01-31 23:59:00' ] ,     
        ['room_id' ,  6 ] ,     
        ['client_id' ,  1 ] ,     

    ] , 
  
];

$base_query = false ;
foreach ($conditions as $k=>$condition )
{
    $query = Contact::selectRaw("SUM(stats) as total , '$k' as 'title'   ")->where($condition) ;
    if($base_query === false )
        $base_query = $query ;
    else
        $base_query->union($query);
}

$results = $base_query->get() ;

   foreach ($results as $result )
   {
       dump($result->title , $result->total );
   }
