What is the correct BDM Custom Query?

Hello,

Here my BDM (3 objects)

I want to find an EMPLOYE from a CONTACT.NAME

Request 2 :

search an EMPLOYE form a Phone Number

CustomQuery on EMPLOYEE

Is the request is:

select e from EMPLOYEE e where e.phone.phonenumber = :phonenumber?

of (source Wikipedia https://en.wikibooks.org/wiki/Java_Persistence/JPQL#Aggregation_functions)

SELECT e FROM Employee e JOIN e.phone p WHERE p.phonenumber = :phonenumber

Request 3
