            "updated_at": null,
            "customer_name": "rahul farm"
        },            
]

這是我的查詢

$wdata= DB::table('weekly_billing')
                ->Join('customers', 'weekly_billing.customer_id', '=', 'customers.id')
                ->select('weekly_billing.*','customers.customer_name','customers.bill_period')
                ->where('weekly_billing.bill_period','monthly')
                ->get();

我想獲取最近一個月的記錄，就像這里我只想獲取 sept 記錄，我正在使用 laravel 任何幫助將不勝感激

Answer 1

您可以像這樣修改查詢：

$wdata= DB::table('weekly_billing')
    ->join('customers', 'weekly_billing.customer_id', '=', 'customers.id')
    ->select('weekly_billing.*','customers.customer_name','customers.bill_period')
    ->where('weekly_billing.bill_period','monthly')
    ->where('month', Carbon::now()->format('M Y'))
    ->get();

MY格式的結果應該是Sep 2021年Sep 2021 （在撰寫本文時）。

基於您的計費范圍的通用方法是：

$wdata= DB::table('weekly_billing')
    ->join('customers', 'weekly_billing.customer_id', '=', 'customers.id')
    ->select('weekly_billing.*','customers.customer_name','customers.bill_period')
    ->whereRaw(Carbon::now()->format('Y m d').' BETWEEN from_date AND to_date')
    ->get();
