如何在没有表列名的 laravel where 子句中运行查询？

Question

如何在 Laravel 中进行此查询，我是 laravel 中的新手

 Product_Type::addSelect([
            'p_name' => Product::select('p_name')->whereColumn('products.id','product_types.products_id'),
            'product_types.pt_name',
            'sale_qty' => Stock::selectRaw('SUM(stock_value)*-1')
                ->whereColumn('stocks.product_types_id','product_types.id')
                ->whereRaw('stock_value < 0')
                ->where('stock_type','sale')
                ->whereBetween('stock_date',[$reqFromDate,$reqToDate])
                ->whereIn('id', Bill::select('stocks_id')
                    ->where('status',1)
                    ->whereIn('customers_id', Customer::select('id')
                        ->where('customers.sale_mans_id',$reqSalemanId))),
            'return_qty' => Stock::selectRaw('SUM(stock_value)*-1')
                ->whereColumn('stocks.product_types_id','product_types.id')
                ->whereRaw('stock_value < 0')
                ->where('stock_type','return')
                ->whereBetween('stock_date',[$reqFromDate,$reqToDate])
                ->whereIn('id', Bill::select('stocks_id')
                    ->where('status',1)
                    ->whereIn('customers_id', Customer::select('id')
                        ->where('customers.sale_mans_id',$reqSalemanId))),
        ])->where('product_types.status',1)->get()

它的工作，但我只想得到sale_qty > 0所以当在 where 子句中设置 sale_qty 查询然后得到错误我想更正这个查询

Product_Type::addSelect([
            'p_name' => Product::select('p_name')->whereColumn('products.id','product_types.products_id'),
            'product_types.pt_name',
            'sale_qty' => Stock::selectRaw('SUM(stock_value)*-1')
                ->whereColumn('stocks.product_types_id','product_types.id')
                ->whereRaw('stock_value < 0')
                ->where('stock_type','sale')
                ->whereBetween('stock_date',[$reqFromDate,$reqToDate])
                ->whereIn('id', Bill::select('stocks_id')
                    ->where('status',1)
                    ->whereIn('customers_id', Customer::select('id')
                        ->where('customers.sale_mans_id',$reqSalemanId))),
            'return_qty' => Stock::selectRaw('SUM(stock_value)*-1')
                ->whereColumn('stocks.product_types_id','product_types.id')
                ->whereRaw('stock_value < 0')
                ->where('stock_type','return')
                ->whereBetween('stock_date',[$reqFromDate,$reqToDate])
                ->whereIn('id', Bill::select('stocks_id')
                    ->where('status',1)
                    ->whereIn('customers_id', Customer::select('id')
                        ->where('customers.sale_mans_id',$reqSalemanId))),
        ])->where('product_types.status',1)
        ->whereRaw(Stock::selectRaw('SUM(stock_value)*-1')
            ->whereColumn('stocks.product_types_id','product_types.id')
            ->whereRaw('stock_value < 0')
            ->where('stock_type','sale')
            ->whereBetween('stock_date',[$reqFromDate,$reqToDate])
            ->whereIn('id', Bill::select('stocks_id')
                ->where('status',1)
                ->whereIn('customers_id', Customer::select('id')
                    ->where('customers.sale_mans_id',$reqSalemanId))) > 0)->get()

在 MySQL 查询中，根据我的要求显示正确的结果

SELECT 
(SELECT p_name FROM products WHERE id=product_types.products_id) AS p_name, 
pt_name, 
(SELECT SUM(stock_value)*-1 FROM stocks WHERE product_types_id=product_types.id AND stock_value < 0 AND stock_type='sale' AND stock_date BETWEEN '2022-07-01' AND '2022-08-31' AND id IN (SELECT stocks_id FROM bills WHERE status=1 AND customers_id IN (SELECT id FROM customers WHERE sale_mans_id=1))) AS sale_qty, 
(SELECT SUM(stock_value)*-1 FROM stocks WHERE product_types_id=product_types.id AND stock_value < 0 AND stock_type='return' AND stock_date BETWEEN '2022-07-01' AND '2022-08-31' AND id IN (SELECT stocks_id FROM bills WHERE status=1 AND customers_id IN (SELECT id FROM customers WHERE sale_mans_id=1))) AS return_qty 
FROM product_types 
WHERE 
status =1 AND 
(SELECT SUM(stock_value)*-1 FROM stocks WHERE product_types_id=product_types.id AND stock_value < 0 AND stock_type='sale' AND stock_date BETWEEN '2022-07-01' AND '2022-08-31' AND id IN (SELECT stocks_id FROM bills WHERE status=1 AND customers_id IN (SELECT id FROM customers WHERE sale_mans_id=1))) > 0;

因为 where 子句不允许没有列名所以没有列名如何管理

Answer 1

您可以使用->whereRaw并根据需要定义条件。 它将作为字符串插入到完整查询中，无需任何修改。 这样你就可以完全控制它。
