如何在oracle中显示用户的所有特权？

您可以尝试以下视图。

SELECT * FROM USER_SYS_PRIVS; 
SELECT * FROM USER_TAB_PRIVS;
SELECT * FROM USER_ROLE_PRIVS;

DBA和其他超级用户可以使用DBA_这些相同视图的版本找到授予其他用户的特权。它们包含在文档中。

这些视图仅显示直接授予用户的特权。查找所有特权，包括通过角色间接授予的特权，都需要更复杂的递归SQL语句：

select * from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER' order by 1,2,3;
select * from dba_sys_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3;
select * from dba_tab_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3,4;
