By default ISAPI_Rewrite Manager will mark configuration files with hidden attribute - this will prevent the file from being requested directly by a remote user.

默认情况下ISAPI_Rewrite将把配置文件的属性标记为隐藏——这将保护文件不受远程用户的修改请求。

The IMPLICITLY HIDDEN attribute on a CREATE or ALTER TABLE statement specifies that the column is not visible in SQL statements unless the column is explicitly referenced by name.

CREATE或ALTER table语句中的IMPLICITLY hidden属性表示，除非根据名称显式引用列，否则该列在sql语句中不可见。

youdao

For row change timestamp columns only, if the column is defined with the IMPLICITLY HIDDEN attribute, then it is not externalized when there is an implicit reference to the columns of the table.

对于行修改时间戳列(只针对这种列)，如果该列使用IMPLICITLY hidden属性定义，那么当对表列进行隐式引用时，不会对该列执行外部化。
