Requirement : Change the All child Contact records Field (Title) when we update the Account (industry) Field.
trigger updatechaildrecords on Account (After update) {
Set<Id> wanttoupdateIDs = Trigger.oldmap.Keyset();
List<Account> Acc = [SELECT Id, Name,industry, (select ID, AccountID,Title from Contacts) FROM Account WHERE Id in :wanttoupdateIDs];
system.debug('********'+Acc);
List<Contact> childrenToUpdate = new List<Contact>();
for(Account AA: Acc){
for(Contact Con: AA.Contacts)
{
con.Title = AA.industry;
childrenToUpdate.add(Con);
}
}
update childrenToUpdate;
}
