Solution 1

understand what the && r.RateList2 is doing here

&& -> Adding multiple condition to WHERE clause
r.RateList2 -> looks like r object has such implementation. It's a property exposed to be used.

Ok just so I understand, there is no column on the table called RateList2 but there are two foregin key columns present. Is the RateList2 refrencing one of those columns?

It's difficult to confirm such things as you can see the details but not us.
