ORA-02030的解决

平时需要给一些用户赋予动态性能视图的查询权限，今天碰到的问题如下：

SQL> conn / as sysdba
Connected.
SQL> grant select on v$session to hr;
grant select on v$session to hr
                *
ERROR at line 1:
ORA-02030: can only select from fixed tables/views

可以查看相对的表名是什么，赋予权限后就可以了。

SQL> select synonym_name,table_name from dba_synonyms where synonym_name='V$SESSION';

SYNONYM_NAME                   TABLE_NAME
------------------------------ ------------------------------
V$SESSION                      V_$SESSION

SQL> GRANT SELECT ON V_$SESSION TO HR;

Grant succeeded.

SQL> CONN HR/HR
Connected.
SQL> DESC V$SESSION;

。。。。。。。。
