Javascript 续写多个左连接

我有

产品

，

qtyProducts

，

订单

和

订单产品

表格 我想得到

SUM（qtyBuyedProducts）

和

SUM（qtySelledProducts）

SQL中的真值查询是（两个左连接）：

我在Sequelize中尝试过：

product.findAll(
  {
    group:'id',
    include:  [
      {
        model: qtyProduct,
        attributes: [[sequelize.fn('SUM', sequelize.col('qty')),'qty_buyed']],
        required: false
      },
      {
        model: ProductOrder,
        attributes: [[sequelize.fn('SUM', sequelize.col('qty')),'qty_selled']],
        required: false
      }
    ]
  })

但我犯了个错误
请帮帮我
我从“邮递员”那里得到了这个错误

}

尝试将查询更改为使用嵌套的SELECT，我认为使用grioup by的左连接可能是问题的原因，因为

qtyProducts

和

ProductOrders

SELECT 
    products.code,
    COALESCE(
        (
            SELECT
                SUM(qty)
            FROM 
                qtyProducts
            WHERE 
                productId = products.id
        )
    , 0) AS qty_selled,
    COALESCE(
        (
            SELECT
                SUM(qty)
            FROM 
                ProductOrders
            WHERE 
                productId = products.id
        )
    , 0) AS qty_buyed
FROM 
    products 
GROUP BY 
    products.id

“但是我得到一个错误”您可以分享这个错误吗？我得到了这个错误消息

“sqlMessage”：“字段列表中的'qty'列不明确”

什么错误？你可以编辑这个问题来包含错误，而不是把它放在评论里吗？我编辑这个帖子谢谢你，这是正确的，有人能把它翻译成续集吗
