Bulk Trigger

Hi,

 

I need to create a trigger but I have problems to create it in a "bulk" way. This is the requirement:

 

I have accounts which are related to another one (called the main). I can have up to 15 accounts related to this main one.

 

When some field of the main account, as the account name or address, are modified, I need to replicate this change to the accounts that are related to this main one. This change doesnt have to be replicated always, just when the related accounts fulfills a condition based on its accountrecordtype

 

I can do

 

For [a: in trigger.new]{

Account RelatedAccount=[SELECT id, recordtypeId FROM Account Where RelatedAccountId:=a.Id];

 

}

 

But this wouldnt be the bulk way and I would probably get errors.

 


Any help is appreciated.

Thanks,

Antonio

You are correct in this assumption. Your code would run okay outside of a bulk environment (e.g. a user editing a record), but would fall flat when using an import wizard or the data loader. Instead, you would want to do something like this:

 

for(account a:[select id,recordtypeid,relatedaccountid from account where relatedaccountid in :trigger.new]) {
  // Trigger.newMap.get(a.relatedaccountid) is the account in the trigger.
  // a is the related account for this loop iteration
}

Edit: Small modification to the filter criteria.

Thanks a lot sfdcfox. I paste my trigger code in case it might help someone:

 

trigger UpdateDuplicities on Account (after update) {
	List<Account> duplicities = new Account[]{};
