Hi,

Is it possible to have 2 derived tables in SQL Update command? For example, I created the following Update (which works):
update Projects set SpentTest = PoSum.TotPo from (select 
PurchaseOrders.ProjectAccount, sum(PurchaseOrders.PoAmount) as TotPo 
from PurchaseOrders group by ProjectAccount) as PoSum 
where Projects.ProjectAccount = PoSum.ProjectAccount
But I actually need to update the column SpentTest on the SUM() in another table as well. So I would have to have two FROM but I don't know what is the right syntax (if it is possible at all).

TIA.
