ORA-01039: insufficient privileges onunderlying objects of the view

视图基本对象的权限不足，一直困扰好几天的问题，让业飞一看就解决了，⊙﹏⊙b汗啊，对tab视图的访问权限不够啊，果然换了一张表dept就可以查看执行计划了。过程如下：

SQL> conn scott/tiger

Connected.

SQL> set autotrace on;

SQL> select * from tab;

TNAME TABTYPE CLUSTERID

------------------------------ -----------------

DEPT TABLE

EMP TABLE

BONUS TABLE

SALGRADE TABLE

MYTABLE TABLE

换了一张访问对象：

SQL> select * from dept;

那么，如何解决查看tab的执行计划呢？

SQL> show user

USER is "SYS"

SQL> grant select any dictionary toscott;

Grant succeeded.

SQL> conn scott/tiger

Connected.

SQL> set autot traceonly

SQL> select * from tab;
