從SQL Server查詢得不到正確的輸出

ALTER PROCEDURE [dbo].[Sp_GetEmailForMailing] 
    -- Add the parameters for the stored procedure here 
    @end int=1000 
AS 
BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from 
    -- interfering with SELECT statements. 
    SET NOCOUNT ON; 

    -- Insert statements for procedure here 
    SELECT top(500) RegistrationID, EmailID from dbo.Candidate_RegistrationData 
    where status_flag=1 and payment_status=2 
    and RegistrationID NOT IN (SELECT top(@end) RegistrationID from dbo.Candidate_RegistrationData 
    where status_flag=1 and payment_status=2) order by RegistrationID 
END

這是我的存儲過程。在這我想從500行，但我從250行號得到....任何人都知道爲什麼會發生......謝謝從SQL Server查詢得不到正確的輸出

你的意思是說，第一@end註冊將被跳過？按登記ID升序排序？ – Pankaj 2011-06-04 09:27:25

用作NOT IN的數據源的子查詢沒有ORDER BY條款。因此，查詢引擎可以按照它認爲合適的順序自由選擇TOP(@end)行。

我希望你想跳過頂部@end登記，順序按RegistrationID

你應該試試下面的代碼。

ALTER PROCEDURE [dbo].[Sp_GetEmailForMailing] 

@end int = 1000 

AS 

SET NOCOUNT ON; 

BEGIN 
    Select Top(500) RegistrationID, EmailID From 
    (
     Select Row_Number() Over(Order by RegistrationID) as RowId, 
        RegistrationID,  
        EmailID,  
        status_flag, 
        payment_status 
     From dbo.Candidate_RegistrationData 
     Where status_flag = 1 and payment_status = 2 
    )T 
    Where RowId > @end and status_flag = 1 and payment_status = 2 
    Order By RegistrationID 
End
