Getting Person account properties from a User

if I have a user that has "plugged" a person account throught the User.ContactId,

      Account a = handleAccount(create, u, attributes);    // a    gets an account object       
      Id accountId = a.Id;     
      User U  ....
      U.ContactId = [select PersonContactId  FROM account where ID =: accountId].PersonContactId; 

How can I do to refer to all the account properties from User?  Is there something like   U.ContactId__r.personemail?

Hi Jose,

Since the ContactID is not a true reference ,you will have to query the information back for users.
map<Id,user> mapIdByuser = new map<Id,User>([Select Id,email from User where ContactId in :setContacts]);
map<Id,User> mapContactIdByUser = new map<Id,User>();
for(User u :mapIdByuser.values()){
Please mark this post as solved if it helps.

Best Regards,
