删除表#SVer

这些命令来自我的计算机 (DBA) 和开发人员的。对于开发者，它给出了几个权限错误：

对象“server”、数据库“master”上的 VIEW SERVER STATE 权限被拒绝。服务器主体“MYDOMAIN\john.doe”在当前安全上下文下无法访问数据库“model”。
用户“MYDOMAIN\john.doe”登录失败。原因：无法打开明确指定的数据库 'MODEL'。[客户：10.90.90.10]
用户“MYDOMAIN\john.doe”登录失败。

对我来说，它给出了这个错误：

无法删除表“#SVer”，因为它不存在或您没有权限。

我不知道是什么应用程序导致了这些查询，因此不知道这些烦人的错误。通过查看查询，您有什么想法吗？我能做些什么来调查？

Answer 1

这是当您单击instance name->时运行的查询 SSMS properties。要确认使用 TSQL 模板启动快速SQL Profiler 跟踪，过滤到您的登录名，然后右键单击服务器名称并选择properties，您应该会在跟踪中看到相同的查询滚过。它的细节在 SSMS 版本之间有所不同，但它们几乎都坚持相同的基本查询。

这个#Sver错误很有趣，但不是一个值得关注的关键问题。您是否安装了与 SSMS 集成的任何 3rd 方工具？也许这些也是原因的一部分。
