Business rules require a Contact to always be created when a new Account is created.
What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?

  1. Use the Database.Delete method if the Contact insertion fails.
  2. Use the Database.Insert method with allOrNone set to False.
  3. Disable Validation rules on Contacts and set default values with a Trigger.
  4. Use setSavePoint() and rollback() with a try/catch block.

Answer(s): D



trigger AssignOwnerByRegion on Account ( before insert, before update )
{
List<Account> accountList = new List<Account>();
for( Account anAccount : trigger.new )
{
Region__c theRegion = [
SELECT Id, Name, Region_Manager__c
FROM Region__c
WHERE Name = :anAccount.Region_Name__c
];
anAccount.OwnerId = theRegion.Region_Manager__c;

accountList.add( anAccount );
}
update accountList;
}

Consider the above trigger intended to assign the Account to the manager of the Account’s region.
Which two changes should a developer make in this trigger to adhere to best practices? (Choose two.)

  1. Use a Map to cache the results of the Region c query by Id.
  2. Move the Region c query to outside the loop.
  3. Remove the last line updating accountList as it is not needed.
  4. Use a Map accountMap instead of List accountList.

Answer(s): B,C



Example 1:
AggregateResult[] groupedResults = [SELECT CampaignId, AVG(Amount) FROM Opportunity GROUP BY CampaignId];
for (AggregateResult ar : groupedResults)
{
System.debug('Campaign ID' + ar.get('CampaignId'));
System.debug('Average amount' + ar.get('expr0'));
}

Example 2:

}

Example 3:
AggregateResult[] groupedResults = [SELECT CampaignId, AVG(Amount) FROM Opportunity GROUP BY CampaignId];
for (AggregateResult ar : groupedResults)
{
System.debug('Campaign ID' + ar.get('CampaignId'));
System.debug('Average amount' + ar.get.AVG());
}

Example 4:
AggregateResult[] groupedResults = [SELECT CampaignId, AVG(Amount) theAverage FROM Opportunity GROUP BY CampaignId];
for (AggregateResult ar : groupedResults)
{
System.debug('Campaign ID' + ar.get('CampaignId'));
System.debug ('Average amount' + ar.theAverage);
}
