Question

我正在使用查询来计算每个月的列总和，问题是当我获取数据并且一个月没有数据时，该月没有行，那么我不知道哪个是哪个月份，如果月份金额为0，则返回0会很有帮助，这是查询：

$test = DB::table('actuals')
->Where('company_id',$id)
->Where('account_level_l','LIKE','%Income%')
->select(DB::raw('SUM(amount) as total_amount'))
->groupBy(DB::raw('MONTH(date) ASC'))->get();

这是返回的对象，从12个月10开始有数据：

Collection {#1381 ▼
  #items: array:10 [▼
    0 => {#1370 ▼
      +"total_amount": 133409.46
    }
    1 => {#1371 ▼
      +"total_amount": 77421.36
    }
    2 => {#1372 ▼
      +"total_amount": 78193.81
    }
    3 => {#1373 ▼
      +"total_amount": 940477.66
    }
    4 => {#1374 ▼
      +"total_amount": 81713.1
    }
    5 => {#1375 ▼
      +"total_amount": 64792.43
    }
    6 => {#1376 ▼
      +"total_amount": 85099.41
    }
    7 => {#1377 ▼
      +"total_amount": 127753.07
    }
    8 => {#1378 ▼
      +"total_amount": 62953.11
    }
    9 => {#1379 ▼
      +"total_amount": 356.61
    }
  ]
}

您只需要像这样选择查询中的月份号：

$test = DB::table('actuals')
->Where('company_id',$id)
->Where('account_level_l','LIKE','%Income%')
->select(DB::raw('SUM(amount) as total_amount, MONTH( date ) as month'))
->groupBy(DB::raw('MONTH(date) ASC'))->get();

这将给出每一行的number of month和total_amount

Laravel查询以获取每个月的列总和
