ORA-01727 view赋权with grant option

Jun 07, 2016 pm 04:00 PM

ORA-01720: grant option does not exist for

ORA-01720: grant option does not exist for 'SCOTT.LOCK1'
该问题出现在将view赋权给另外的用户时,而该view中引用了第三个用户下的表。

例如:
我有三个用户:scott,roy,test
在roy下创建一个view引用到scott的表
然后将roy下的view的访问权限给test
如果按普通的赋权模式,此时就会报出ORA-01720错误。

解决方法是:
在将表scott下的表访问权限赋权给roy用户时,加上with grant option。
这样当view赋权给test时就会自动把scott表的权限给test,这样就不会出错了。

实验测试:
环境本地linux RedHat 5, Oracle 11gR2

1.用dba用户登录,先试着创建视图roy.new_view,报错
SQL> connect dbmgr/dbmgr;
Connected.

SQL> create view roy.new_view(id,comm) as select id,comm from scott.lock1;
create view roy.new_view(id,comm) as select id,comm from scott.lock1
                                                              *
ERROR at line 1:
ORA-00942: table or view does not exist

2.给roy赋普通权限后,创建视图成功
SQL> grant select on scott.lock1 to roy;

Grant succeeded.

SQL> create view roy.new_view(id,comm) as select id,comm from scott.lock1;

View created.

3.将视图赋权给test用户,报错ORA-01720
SQL> grant select on roy.new_view to test;
grant select on roy.new_view to test
                    *
ERROR at line 1:
ORA-01720: grant option does not exist for 'SCOTT.LOCK1'

4.给roy赋权时加上with grant option 选项再将视图赋权给test用户,成功
SQL> grant select on scott.lock1 to roy with grant option;

Grant succeeded.

SQL> grant select on roy.new_view to test;

Grant succeeded.
