Trigger Help

Hi,

 

Can any one provide a sample code to perform the Rollup Sum() Trigger.

Thanks

Hi,

 

Aggregate functions allow you to roll up and summarize your data for analysis


Try the below code snippet as reference

trigger DealTrigger on DealInterest__c (before update,before insert)
{

DealInterest__c di;
Deal__c dd;
AggregateResult[] lid;
String str;

for(DealInterest__c d:Trigger.New)
{
dd=[Select Name From Deal__c where id=:d.DealL__c ];

lid=[Select sum(DealNum__c)num from DealInterest__c where DealL__c=:d.DealL__c ];
if(lid[0].get('num')==null)
{
d.DealNum__c=1;
d.IntID__c=d.DealL__c+'-000'+String.valueof(1);

}

}
}

Why you want to it from Trigger, you van jsut create a roll up summery field.

 

Any how if you wnat to do it from trigger

then use 

 List<AggregateResult> aggResult= [Select sum(field name) <alias o filed> From Object WHERE field_name=:?];
