Split fee among products in order

Wed, 18 Feb 2015 19:49:31 GMT

Hi!

I have two tables, similar to these:

Orders:

Load * inline

[

OrderID, Fee

1, 20.0

2, 0.0

3, 12.50

4, 13.50

];

Items:

Load * inline

[

OrderID, Qty, ProductName,

1, 12, "Egg"

1, 2, "Apple"

1, 1, "Milk"

2, 1, "Egg"

2, 1, "Milk"

3, 20, "Apple"

4, 40, "Milk"

4, 10, "Apple"

];

I want to present sales per product but be able to deduct fees. However, the fees are given per order, and have to be split among the products in that particular order. How can I achieve this? I have a feeling there is an easy way to do this.

You want to Deduct Fee from Qty?

Ah, sorry. Each product should have a price too. See new table below.

So I might want to calculate the total sales as:

sum(Qty*Price) with ProductName as the dimension.

But if I want to deduct the fees, then what should I do? Something like:

sum(Qty*Price - FeePerProduct?)

Items:

Load * inline

[

OrderID, Qty, ProductName, Price

1, 12, "Egg", 1

1, 2, "Apple", 2

1, 1, "Milk", 5

2, 1, "Egg", 1

2, 1, "Milk", 5

3, 20, "Apple", 2

4, 40, "Milk", 5

4, 10, "Apple", 2

];

maybe

sum(Qty*Price)

sum(aggr(sum(Fee)/count(total <OrderID> ProductName),ProductName, OrderID))

column(1) -column(2)

Thanks, that seems to work! And seeing that aggr function gave me the even better idea to create an OrderInfo table in the load script, using GROUP BY, which will basically calculate the total count of products and total value of each order. With those numbers on hand, it is easy to split the fee among the products later on.

Thanks again!
