Sql 如何检查oracle数据库中分配给模式、角色的对象的权限（DDL、DML、DCL）？

大多数时候，我们都在为获取模式、角色及其对象的权限细节而与一些愚蠢的事情作斗争，并试图找到一些简单的方法来获取关于它的所有细节，以及生成大量grant语句以供进一步执行的伪查询代码。现在我们来了解它。

简单介绍一下数据字典视图前缀：

ALL_    -Describes PUBLIC Object grants.
USER_   -Describes current user Object grants.
DBA_    -Describes all object grants in the database.

ROLE_ROLE_PRIVS     -describes the roles granted to other roles. 
ROLE_SYS_PRIVS      -describes system privileges granted to roles.
ROLE_TAB_PRIVS      -describes table privileges granted to roles. 
DBA_ROLE_PRIVS      -describes the roles granted to all users and roles in the database.
DBA_SYS_PRIVS       -describes system privileges granted to users and roles.
DBA_TAB_PRIVS       -describes all object grants in the database.
DBA_COL_PRIVS       -describes all column object grants in the database.
