sql - 如何将大数组添加到 SQL 查询？

Question

这是我的风暴代码：

items = store.find((Delivery, Product, Sum(Delivery.quantity)),
                    Delivery.id.is_in(order.id for order in self.orders),
                    Product.id == Delivery.product_id) \
                    .group_by(Delivery.date, Product.id, Delivery.discount) \
                    .order_by(Delivery.date, Product.name, Delivery.discount)

这转换为大约以下 SQL：

   SELECT deliveries.id, products.id, SUM(deliveries.quantity)
   FROM deliveries, products
   WHERE products.id = deliveries.id AND
->       deliveries.id IN (1,10,5,24,122, ...)
   GROUP BY deliveries.date, product.id, delivery.discount
   ORDER BY deliveries.date, product.id, delivery.discount

如果self.orders太长，则会引发太多 SQL 变量异常。

有没有其他方法可以实现这一目标？

我唯一的想法是为每个订单创建一个查询，并使用字典手动组合它们。

Answer 1

• Add it to a temporary table/table variable and link to it.
• Depending on your version of SQL, you might be able to use an XML object

Answer 2

也许只是将这个目标数组分成更小的数组？大约是其大小的 1/3，然后将其合并到脚本端。
