Question #: 160
Topic #: 1
[All CRT-450 Questions]

The Job_Application__c custom object has a field that is a Master-Detail relationship to the Contact object, where the Contact object is the Master. As part of a feature implementation, a developer needs to retrieve a list containing all Contact records where the related Account Industry is `˜Technology' while also retrieving the contact's Job_Application__c records.
Based on the object's relationships, what is the most efficient statement to retrieve the list of contacts?

  • A. [SELECT Id, (SELECT Id FROM Job_Applications_r) FROM Contact WHERE Account.Industry = 'Technology'];
  • B. [SELECT Id, (SELECT Id FROM Job_Applications_r) FROM Contact WHERE Accounts.Industry = 'Technology'];
  • C. [SELECT Id, (SELECT Id FROM Job_Applications_c) FROM Contact WHERE Accounts.Industry = 'Technology'];
  • D. [SELECT Id, (SELECT Id FROM Job_Application_c) FROM Contact WHERE Account.Industry = 'Technology'];

Response A: Contact is parent of Job_Application__c hence it can access child records using "__r" relationship. Account must be a parent of Contact so it is related using Account.xxx.

Selected Answer: A
it could not be C! Come on! Querying child object cannot be done without the suffix __c.

I think the correct answer is B because of the plural form. So it should be Accounts instead of Account

A is the answer. You query the relationship which ends with __r not __c

Selected Answer: A
A should be correct. You can't use Job_Applications__c in select query since Job_Application__c is custom object and child to Contact
