## 场景 ##

当使用SqlServerManagement Studio 进行附加数据库时

选择了磁盘目录下的mdf文件后，点击确定提示

## 实现 ##

这是因为当前计算机用户对mdf文件的权限不够。

找到要附加的mdf文件然后右击-属性

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 2][]

点击编辑权限

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 3][]

然后选择完全控制，将当前的几个用户都要进行完全控制。

mdf文件以及log.mdf文件都要授予权限
