Don't have an account?
Shreya Salesforce Trigger on parent Account to get sum of all child Accounts. I make a custom field 'Total_No_of_Child_Accounts__c'(Number type)on Account Object.
I make Acc1(child object)and Acc2(child object) whose parent is 'Acc3'. My trigger shows only '1'in field 'Total_No_of_Child_Accounts__c'.
Please help me to solve this problem.
trigger TotalChildAccounts on Account (after insert,after Update,after delete,after Undelete)
{
//List<Account> childaccIds= new List<Account>();
//List<Id> ParentaccIds= new List<Id>();
Map<Id,Account> accMap= new Map<Id,Account>();
if(trigger.isInsert || trigger.isUpdate || trigger.isUndelete)
{
for(Account acc:trigger.new)
{
if(acc.ParentId!=null)
{
accMap.put(acc.ParentId,acc);
//childaccIds.add(acc);
//ParentaccIds.add(acc.ParentId);
// System.debug('childaccIds=='+childaccIds);
// System.debug('ParentaccIds=='+ParentaccIds);
}
}
}
if(trigger.isDelete)
{
for(Account acc:trigger.old)
{
if(acc.ParentId!=null)
{
accMap.put(acc.ParentId,acc);
}
}
}
List<Account> FetchParentAccList = [SELECT Id,Name,Total_No_of_Child_Accounts__c,ParentId FROM Account WHERE ParentId IN:accMap.keyset()];
List<Account> accList = new List<Account>();
For(Account achild : FetchParentAccList)
{
if(accMap.containskey(achild.Id))
{
achild.Total_No_of_Child_Accounts__c = FetchParentAccList.size();
accList.add(achild);
}
}
if(accList.size()>0)
{
Update acclist;
}
}

Try the below trigger:
trigger CountChildAccount on Account(after insert, after update, after delete) {
Set<Id> Ids= new Set<Id>();
if(Trigger.isInsert || Trigger.isUpdate){
for(Account acc: Trigger.new){
if(acc.ParentId!=null){
Ids.add(acc.ParentId);
}
}
}
if(Trigger.isDelete){
for(Account acc: Trigger.old){
if(acc.ParentId!=null){
Ids.add(acc.ParentId);
}
}
}
if (!Ids.isEmpty()) {
List<Account> AccountToUpdate = new List<Account>();
for (AggregateResult ar : [SELECT COUNT(ID), ParentID FROM Account
WHERE ParentID IN :Ids GROUP BY ParentID]) {
Id accID = (ID)ar.get('ParentID');
Integer count = (Integer)ar.get('expr0');
Account acc1 = new Account(Id=accID);
acc1.Total_No_of_Child_Accounts__c = count;
AccountToUpdate.add(acc1);
}
if (!AccountToUpdate.isEmpty()) {
update AccountToUpdate;
}
}
}
