【中文标题】我在运行查询时启动了 RDS SQL Server（SQL Server Web 版）并抛出了权限被拒绝错误

【英文标题】：I launched RDS SQL Server (SQL Server Web Edition) when I ran the query and It is throwing permission denied error

【发布时间】：2021-09-03 08:21:51

【问题描述】：

我在查询下方运行，错误是

对象“sysschedules”、数据库“msdb”、架构“dbo”的 SELECT 权限被拒绝。

SQL Server 网络版 引擎版本 15.00.4073.23.v1

如何解决？

       [sDBP].[name] AS [JobOwner],
       [sCAT].[name] AS [JobCategory],
       [sJOB].[description] AS [JobDescription],
       CASE [sJOB].[enabled] WHEN 1 THEN 'TRUE' WHEN 0 THEN 'FALSE' END AS [IsEnabled],

【问题讨论】：

我强烈建议您格式化查询

你需要养成在写作中善用使用空格和换行符的习惯，包括代码.它使难以阅读的文本 Far 变得更易读。至于错误，它实际上是在告诉您这里的问题。你不明白所说的错误怎么办？

即使我有管理员权限，我也无法授予权限

您如何确定您拥有“管理员权限”？您的意思是您是系统管理员角色的成员吗？此查询是否返回任何行？ use msdb; select * from sys.fn_my_permissions(null, 'database') where permission_name = 'take ownership'

它没有给出任何结果，只有0行受到影响

【参考方案1】：

很遗憾，到目前为止，RDS 不支持此功能。看起来 RDS 不允许您查询这些系统表：

[msdb].[dbo].[sysjobsteps] [msdb].[dbo].[sysjobschedules] [msdb].[dbo].[sysschedules]

对应的 AWS 论坛帖子：https://forums.aws.amazon.com/thread.jspa?threadID=220807

您需要从查询中删除这些表的连接，这会为您提供以下信息 - 可以针对 SQL Server 实例的 RDS 执行：

SELECT [sJOB].[job_id] AS [JobID],
       [sJOB].[name] AS [JobName],
       [sDBP].[name] AS [JobOwner],

       [sJOB].[description] AS [JobDescription],
       CASE [sJOB].[enabled] WHEN 1 THEN 'TRUE' WHEN 0 THEN 'FALSE' END AS [IsEnabled],
       [sJOB].[date_created] AS [JobCreatedOn],
       [sJOB].[date_modified] AS [JobLastModifiedOn],
       [sSVR].[name] AS [OriginatingServerName],
       CASE [sJOB].[delete_level]
            WHEN 0 THEN 'Never'
            WHEN 1 THEN 'On Success'
            WHEN 2 THEN 'On Failure'
