Suhas GB 4 Apex trigger using AggregateResult
Here is my code:
trigger AggregateResult on Contact (after insert, after update) {
if((trigger.isinsert && trigger.isafter) || (trigger.isupdate && trigger.isafter))
{
contact c=trigger.new[0];
if(c.accountid!=null)
{
AggregateResult[] ar=[select SUM(Contact_Amount__c) ss from contact where accountid=:c.accountid];
Integer d=(Integer)ar[0].get('ss');
account ac=new account(id=c.accountid);
ac.Total_Amount_of_Contacts__c=decimal.valueOf(String.valueOf(ar[0].get('ss')));
update ac;
}
}
}
I want the sum of Amount field in Contact to appear on Account field. But I'm getting this error:
Apex trigger AggregateResult caused an unexpected exception, contact your administrator: AggregateResult: execution of AfterUpdate caused by: System.TypeException: Invalid conversion from runtime type Decimal to Integer: Trigger.AggregateResult: line 11, column 1
Please provide me a solution for this.

Hi Suhas GB 4,
I believe the type of Contact_Amount__c be either a decimal or double.
You can't convert decimal or double to Integer in that way.
You have to use Integer.valueOf(ar[0].get('ss'));
This should work , let me know if you face any further issues

Hi,
Please use Double instead of Integer
Hi,
Did you try to change Integer to Double?
Hope the above solution worked for you.
Thanks
