不能授予、拒绝或撤销对 sa、dbo、实体所有者、information_schema、sys 或您自己的权限

Question

我遇到以下错误：

Cannot grant, deny, or revoke permissions to sa, dbo, entity owner, information_schema, sys, or yourself.

当我尝试这些命令时

USE ASPState
GO

GRANT EXECUTE ON CreateTempTables TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON DeleteExpiredSessions TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON GetMajorVersion TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON GetHashCode TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempGetAppID TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempGetStateItem TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempGetStateItem2 TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempGetStateItem3 TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempGetStateItemExclusive TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempGetStateItemExclusive2 TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempGetStateItemExclusive3 TO [R2Server\AAOUser]
GO

GO

GO
GRANT EXECUTE ON TempReleaseStateItemExclusive TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempRemoveStateItem TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempResetTimeout TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempUpdateStateItemLong TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempUpdateStateItemLongNullShort TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempUpdateStateItemShort TO [R2Server\AAOUser]
GO
GRANT EXECUTE ON TempUpdateStateItemShortNullLong TO [R2Server\AAOUser]
GO

那么，我怎么知道我的帐户R2Server\AAOUser对数据库有什么类型的权限ASPState？以及解决错误的方法是什么（以便我可以将这些权限授予我的帐户）？

Answer 1

根据评论，如果您已经是该数据库的 db 所有者，则不需要为该 db 授予任何权限。

现在，为了找出您拥有哪些特定权限，您可以使用以下查询：

• 查找特定数据库的权限：

  USE AdventureWorks2008R2;
  SELECT * FROM fn_my_permissions (NULL, 'DATABASE');
  GO
  

• 在所有服务器上查找权限：

  SELECT * FROM fn_my_permissions(NULL, 'SERVER');
  GO
  

在此处查看其他一些信息：在 MSDN 论坛上查找 SQL Server 登录名和关联的服务器角色。
