Help with a SOQL's query (SUM)

Hi,

I need to do a query in SOQL like this in SQL:

Select SUM(field1), field2 From Table Where condition Group By field2

I Know that It isn't posible, but is there a way to do something seemed?

I would like do something not to calculate this "SUM" by code.

Thanks

you have to write a for loop to calculate this sum()

It's not entirely clear what you are trying to calculate, but Tom Tobin's blog posting has a tip for calculating a sum on groups in a grouping.

Hope this helps.

Hi there,

 

is there any way to loop through the subresult from apex?

 

i got a statement "select Id, (select Amount_Hrs__c from ContractQuotas__r)  from contract" with multiple subrows which have to be summed up as no roll up is helpfull here. usually i'd loop through the list i get back from the query and access the fields via listname.get(position).Fieldname. But i cannot find a way to loop through the subquery-results ...

 

Any hint would be very helpfull. :robothappy:

public void ShowContractEntries(){
		
 getIsPartner();
 string myString = acc.Id;

	
 contrEntries =[select Id, StartDate, Quota__c, Iteration__c, Status, EndDate2__c, EndDate, ContractTerm, 
	        CreatedDate, Account.Type, ContractNumber, Type__c, End_User__r.Name, ContractQuotaUsed__c,
	       (select Amount_Hrs__c from ContractQuotas__r) from contract 
		where Status = 'Activated' and AccountId =: myString.substring(0,15) order by CreatedDate DESC];
		
		for(integer i=0;i<contrEntries.Size();i++){
			
		   for(integer s =0; s < contrEntries.get(i).ContractQuotas__r.size();s++){

                       contrEntries.get(i).ContractQuotas__r.get(s).Amount_Hrs__c);
		       hpc = hpc + contrEntries.get(i).ContractQuotas__r.get(s).Amount_Hrs__c;
		   
                   }
			
		   contrEntries.get(i).ContractQuotaUsed__c = hpc;
		   hpc =0.0;
		}			   
	
		update contrEntries;
		
}

 

Done :) Very simple to loop through the subquery items to sum up something up ... wasn't that obvious too me :)
