Question

I want to use RavenDB for a project I am doing, but before I can, I need figure out how to query nested objects… Let me explain
I have a class like this:

public class Customer
{
 public string Id { get; set; }
 public string Name { get; set; }
 public IList<Orders> { get; set; }
}

Then the Order class:

public class Order
{
 public int OrderNumber { get; set; }
 public decimal OrderAmount { get; set; }
 public bool CustomerBilled { get; set; }
}

I create a bunch of fake data and add it to Raven — some Customers have orders with only CustomerBilled set to true, some with CustomerBilled set to false, and some a mix of true and false on CustomerBilled.

What I need help with, is figuring out how to extract a list of Customers that 1 or more Orders with CustomerBilled set to false.

How would I create a query to do it? I can’t seem to get one to work, and I have no idea how.

Answer 1

The dynamic queries in RavenDB can handle this, I think the following should do what you want (sorry I can’t compile the code right now to verify)

// List of objects - linq
from doc in Customers
where doc.Orders.Any( order => order.CustomeBilled == false)
select doc;
