冲洗打印语句客户端（SQL Server Management Studio中）

Question

请参阅下面的代码：

USE [Test] 
GO 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 
ALTER PROCEDURE [dbo].[Test] 
AS 
BEGIN 
begin tran 
begin try 
    SET NOCOUNT ON; 
    DECLARE @ID int 
    DECLARE @Count int 
    set @Count=0 
    DECLARE Employee_Cursor CURSOR FOR 
SELECT id 
FROM Person3; 
OPEN Employee_Cursor; 
FETCH NEXT FROM Employee_Cursor INTO @ID 
WHILE @@FETCH_STATUS = 0 
    BEGIN  
     WAITFOR DELAY '000:00:01' 
     SET @Count = @Count+1 
     Print @Count   
     FETCH NEXT FROM Employee_Cursor INTO @ID; 
    END; 
    commit tran 
CLOSE Employee_Cursor; 
DEALLOCATE Employee_Cursor; 
end try 
begin catch 
ROLLBACK tran 
end catch 
END 

存储过程运行，然后将下面的输出一下子刷新到客户端（因为有三个记录在：person3）：

1 
2 
3 

如何在每次迭代游标时将输出刷新到客户端？我正在寻找一个与SQL Server 2005兼容的答案。

我试过使用RAISEERROR语句，因为这里描述为：How do I flush the PRINT buffer in TSQL?，但所有语句仍然出现在最后。

对于立即将输出发送到消息窗口的语句，使用RAISERROR严重性0到10和WITH NOWAIT子句的组合。

RAISERROR ('Now that''s what I call a message!', 0, 1) WITH NOWAIT
