Oracle中如何授予某个新用户create table权限,那么这个用户就只有creat table权限，而没有其他权限吗？如select权限？

参考技术A 用拥有CREATE
TABLE
[WITH
ADMIN
OPTION]的用户（比如DBA用户）执行：grant
create
table
to
your_user;
一个用户可以CREATE
TABLE，那他对这个表当然就有SELECT权限了，以及对该表其他操作权限，比如ALTER,INSERT,UPDATE,DROP等。

oracle中怎样让一个用户查询其它用户的trigger？

在工作期间，有时候遇到这种需求，需要将一个用户下的trigger查询权限授予给其他的用户
怎样将某个用户的trigger查询权限，授予其他用户？

方法一：
授予 create any trigger权限。这个权限太大，一般都不会考虑将这种权限授予出去

方法二：
将表的bebug权限授予其他用户。这样就能查看到该用户表上的trigger了

测试：

在其他的会话创建一个trigger

9 /
Trigger created.

将表的debug权限授予erwa
SQL> grant debug on emp to erwa;
Grant succeeded.

再次查询就可以看到scott下面新建立的trigger
SQL> show user
USER is "ERWA"
SQL> select OWNER,TRIGGER_NAME from all_triggers where owner=‘SCOTT‘;
OWNER TRIGGER_NAME
------------------------------ ------------------------------
SCOTT TEST
