NEW QUESTION # 156
A company has a custom object, Order__c, that has a custom picklist field, Status__c, with values of `"New', `"In Progress', or `"Fulfilled' and a lookup field, Contact__c, to Contact.
Which SOQL query will return a unique list of all the Contact records that have no `"Fulfilled' Orders?
Answer: D
Explanation:
The correct SOQL query to return a unique list of Contact records that have no 'Fulfilled' Orders is one that selects Ids from the Contact object where the Contact Id is not in the set of Contact Ids related to 'Fulfilled' Orders. This is done by a subquery that selects the Contact__c field from the Order__c records where the Status__c is 'Fulfilled'.
NEW QUESTION # 157
A company has reference data stored in multiple custom metadata records that represent default information and delete behavior for certain geographic regions.
