Question

请参阅以下代码：

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

运行存储过程，然后将以下输出一次性刷新到客户端（因为在person3中有三条记录）：

1
2
3

如何在光标的每次迭代中将输出刷新到客户端？我正在寻找与SQL Server 2005兼容的答案。

我已尝试使用RAISEERROR语句，如下所示：How do I flush the PRINT buffer in TSQL?，但所有语句仍然出现在最后。

使用RAISERROR严重性为0到10的组合和WITH NOWAIT子句，用于立即将输出发送到Messages窗口的语句。

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