SQL Query And SSRS Query

Question

Может ли кто-нибудь помочь мне, почему этот запрос работает нормально в SSMS, но не в SSRS?

SELECT  
    SUM(AMOUNTMST) AS 'Balance' 
FROM   
    BANKACCOUNTTRANS 
WHERE  
    (ACCOUNTID IN (@Bank_AccountID)) 
    AND (DATAAREAID = 'RAS') 
    AND (TRANSDATE BETWEEN '2013-12-31 00:00:00' AND @From_Date) 
GROUP BY 
    AccountID 

Answer 1

SELECT AccountID 
     ,SUM(AMOUNTMST) AS [Balance] 
FROM BANKACCOUNTTRANS 
WHERE (ACCOUNTID IN (@Bank_AccountID)) 
    AND (DATAAREAID = 'RAS') 
    AND (TRANSDATE BETWEEN '20131231' AND @From_Date) 
Group By AccountID
