Sql server 2005 如何在限制权限的同时执行sp_send_dbmail

是否有一种方法可以让我的数据库中的用户访问msdb.dbo.sp\u send\u dbmail，而无需将其添加到msdb数据库和DatabaseMailUserRole

我试过这个：

ALTER PROCEDURE [dbo].[_TestSendMail]
(
  @To NVARCHAR(1000),
  @Subject NVARCHAR(100),
  @Body NVARCHAR(MAX)
)
WITH EXECUTE AS OWNER
AS 
    BEGIN
        EXEC msdb.dbo.sp_send_dbmail @profile_name = N'myProfile',
            @recipients = @To, @subject = @Subject, @body = @Body
    END

但我得到了这个错误：

The EXECUTE permission was denied on the object 'sp_send_dbmail', database 'msdb', schema 'dbo'.

谢谢

一种可能的解决方案是将邮件封装为一个存储过程，例如mail\u error\u as\u MAILER（稍后您将调用它） 和另一个存储过程 e、 g

但这需要： *硬编码密码（确保用户无法查看存储过程的定义…） *允许用户访问sp_oacreate等。。。（打开其他安全问题，例如DOS）

这样他们就只能按你想要的方式使用邮件，而不允许他们邮寄其他东西

或者更安全， 让用户将邮件放入某种邮件队列（您可以控制他们可以放入什么），并让代理帐户定期发送这些邮件

---

或者：允许他们发送邮件，但在滥用时使用带有生锈钉子的大棒

你的方法是可以的，但是你的包装程序必须在msdb数据库中。 然后，执行“EXEC msdb.dbo.\u TestSendMail”

这仍然存在对dbo.\u msdb中的TestSendMail的权限问题。 但是public/EXECUTE就足够了：它只公开您需要的3个参数

如果有疑问，请添加加密。这足以阻止任何没有系统管理员权限的人查看代码

USE msdb
GO
CREATE PROCEDURE [dbo].[_TestSendMail]
(
  @To NVARCHAR(1000),
  @Subject NVARCHAR(100),
  @Body NVARCHAR(MAX)
)
-- not needec WITH EXECUTE AS OWNER
AS 
    BEGIN
        EXEC dbo.sp_send_dbmail @profile_name = N'myProfile',
            @recipients = @To, @subject = @Subject, @body = @Body
    END

实际上，您可以使用证书签名的存储过程执行此操作，而不必在msdb中执行此操作：

CREATE DATABASE TestDBMail
GO

USE [TestDBMail]
GO

CREATE PROCEDURE [dbo].[TestSendMail]
(       
        @To NVARCHAR(1000),  
        @Subject NVARCHAR(100),  
        @Body NVARCHAR(MAX)
)
WITH EXECUTE AS OWNER
AS
BEGIN
        EXEC msdb.dbo.sp_send_dbmail 
                        @profile_name = N'Database Mail Profile',
                        @recipients = @To, 
                        @subject = @Subject, 
                        @body = @Body    
END
GO

GO

GO

USE [TestDBMail]
