Consider an order. An order will have one or more line items. Each line item is for a particular product.

Given a filter table with a couple of products, how would I get the order id's that had at least all of the products listed in the second table?

table Orders(
  OrderId int
)

table LineItems (
  OrderId int,
  LineItemId int,
  ProductId int
)

table Filter (
  ProductId int
)

data

Orders
OrderId
--------
1
2
3


LineItems
OrderId   LineItemId   ProductId
-------   ----------   ---------
1         1            401
1         2            502
2         3            401
3         4            401
3         5            603
3         6            714

Filter
ProductId
---------
401
603

Desired result of the query: OrderId: 3
