JOIN triangle relationship

    السؤال

  • The relationship:

    Profil>Branch>City 
    Profil>Hotel>City 

    command:

    from p in Profil.getData() 
    join b
    in Branch.getData() on p equals b 
    join h
    in Hotel.getData() on p equals h 
    join c
    in City.getData() 
                           
    ^how to reuse the equals join 

    Can I join City to Branch and Hotel table? Can I just clone the c without City.getData()?
