如何获取最后一行中列的总和

Question

select csm.csmCustomerName, cur.curNameOfCurrency, 
sum(sot.sotItemTotalAmount)as 'TotalItemsAmount',
SUM(sorTotalTaxAmountValue) as 'TotalTax',
SUM(sorTotalChargeDetailsAmountValue) as 'TotalCharges',
(sum(sorTotalTaxAmountValue)+sum(sorTotalChargeDetailsAmountValue)+sum(sot.sotItemTotalAmount)) as 'NetAmount'
from dbo.SalesOrder sor join dbo.Currency cur
on sor.sorCurrencyId=cur.curId
join dbo.CustomerMaster csm
on sor.sorCustomerMasterId=csm.csmId
join SalesOrderItemDetails sot
on sot.sotSalesOrderId=sor.sorId
Group by csmCustomerName, curNameOfCurrency with rollup;

我想在各列的最后一行中加TotalItemsAmount，TotalTax，TotalCharges和NetAmount的总和。 在结果集中，我得到每行的重复，任何人都可以纠正我的代码中的错误。
