_MAP

Oracle视图DBA_ACTIVITY_CONFIG_MAP是一个数据字典视图,显示了行为映射表中所有记录的详细信息。它主要用于配置语句活动,以便实施某些策略以及活动和功能的定制。

它的结构如下:

DBA_ACTIVITY_CONFIG_MAP(活动ID,映射ID,MAP_CONTEXT,SECURITY_CLASS, SECURITY_RESTRICTION, USER_OBJECT_NAME, USER_OBJECT_OWNER)

– 活动ID:活动编号
– 映射ID:映射编号
– MAP_CONTEXT:映射上下文
– SECURITY_CLASS:映射安全类
– SECURITY_RESTRICTION:权限限制
– USER_OBJECT_NAME:用户对象名
– USER_OBJECT_OWNER:用户对象所有者

下面是使用这个视图的示例:

此查询可以查询指定的活动ID的映射内容,安全类别和安全限制。
