語法錯誤的SP

Question

可能重複：
Dynamic SELECT TOP @var In SQL Server

爲什麼我在select top @recNo及彼語法錯誤？

create procedure getTopAccounts 
(
@recNo int 
) 
as 
begin 
    select top 1 accDesc, accNum 
    from 
     (select top @recNo accDesc,accNum 
     from 
     ACCOUNTS_TABLE 
     order by 
     accNum desc) 
    as a order by accNum 
end 

Answer 1

...select top (@recNo) accDesc... 

Parametrised TOP需要在括號
