如何在Oracle数据库的DBA_SYS_PRIVS表中标识用户帐户

Question

I'm trying to look for all the users with certain privileges in the DBA_SYS_PRIVS table. The table has a GRANTEE column and according to Oracle Official website, the GRANTEE column shows "Grantee name, user, or role receiving the grant". So how could I know if the GRANTEE is an account or a role? For example, there is role called SYS and also an account called SYS in the Oracle DB. So how do I know if this is an account or role????

Also in table DBA_TAB_PRIVS, there is a column called GRANTEE. And in this table, the column GRANTEE is "Name of the user to whom access was granted". So I am really confused because the "GRANTEE" column means different things in two different tables

Please help, thanksssssssssssssss

No there is no SYS role in Oracle.

 SQL> select * from dba_roles where role='SYS';

 no rows selected

Actually you cant create roles same name as usernames.

 SQL> create role sys;
 create role sys
        *
 ERROR at line 1:
ORA-01921: role name 'SYS' conflicts with another user or role name

To get only the roles without usernames.

SQL>select grantee from dba_sys_privs where grantee not in(select username from all_users);

To get only users without roles.

 SQL>select grantee from dba_sys_privs where grantee in(select username from all_users)
