Dynamic CRM 2011 SOAP RetrieveMultiple xml for querying from two table - soap

Question

I was stuck with Dynamics CRM 2011. I want to create SOAP RetrieveMultiple xml which will fetched the data from two different table using inner join on the basis foreign key.
I have tried many ways but unable to get success.
For my scenarios let's say table A and B is there.
A -- (id, name, address_id)
B -- (srno, address_id, area, city, zip)
Now, I want to get the details from table A & B based on below query,
select A.id, A.name, B.area, B.city, B.zip
from A
INNER JOIN B
ON A.address_id = B.address_id
I'm totally new with Dynamics CRM 2011.
It would be great if you can share some valuable examples.
Thanks in advance.

You can only do inner joins between related entities (1:N), where a.Id = b.aId you need to Retrieve A records from that address and B records from that address.
