Workaround: Workaround Exists
Workaround Description: There's a workaround where you just have to provide a dummy element in the SELECT clause:


select PrimaryBusinessUnit, sum(oli.totalPrice), accountId
from general.salesforce.Opportunity o left outer join general.salesforce.OpportunityLineItem oli ON oli.OpportunityId = o.id,
     general.salesforce.PricebookEntry pbe, general.salesforce.Product2 p
where 	(PricebookEntryId = pbe.Id) AND (p.Id = Product2Id)
and   isClosed=true
and   isWon = true
and   CloseDate > '2008-03-01'
and    accountId = '00130000009SwiLAAS'
group by PrimaryBusinessUnit, accountId


project_key: SOA

If you're executing a query like this:


select PrimaryBusinessUnit, sum(oli.totalPrice)
from general.salesforce.Opportunity o left outer join general.salesforce.OpportunityLineItem oli ON oli.OpportunityId = o.id,
     general.salesforce.PricebookEntry pbe, general.salesforce.Product2 p
where 	(PricebookEntryId = pbe.Id) AND (p.Id = Product2Id)
and   isClosed=true
and   isWon = true
and   CloseDate > '2008-03-01'
and    accountId = '00130000009SwiLAAS'
group by PrimaryBusinessUnit


you end up with a MALFORMED_QUERY exception.
