Oracle synonym 同义词创建与删除
Oracle synonym 同义词 1、Oracle synonym 同义词是数据库当前用户通过给另外一个用户的对象创建一个别名，然后可以通过对别名进行查询和操作，等价于直接操作该数据库对象。 3、Oracle synonym 同义词按照访问权限分为私有同义词、公有同义词。 4、私有同义词：私有同义词只能当前用户可以访问，前提：当前用户具有create synonym 权限。 语法结构： CREATE [OR REPLACE] [PUBLIC] SYSNONYM [当前用户.]synonym_nameFOR [其他用户.]object_name; 解析： 1、create 代码如下： create synonym stuinfo_copy for school.stuinfo; 创建同义词之后，即可使用select *from stuinfo_copy 进行查询 语法结构： DROP [PUBLIC] SYNONYM [用户.]sysnonym_name;

【DB笔试面试514】在Oracle中，同义词的定义及其作用是什么？有关同义词需要注意些什么？
创建同义词必须要有 CREATE ANY SYNONYM、CREATE SYNONYM 系统权限。要创建全局的同义词，必须有CREATE PUBLIC SYNONYN 系统权限。 EMP FOR SCOTT.EMP; Synonym created. create a synonym with same name as object LHR@ora11g > create public synonym s_b for s_b; Synonym created LHR@ora11g > create public synonym s_a for s_b; Synonym created. object LHR@ora11g > create public synonym s_b for s_b; Synonym created.

曲折的10g,11g中EM的安装配置过程(r4笔记第98天)
10g中的EM相对比较简单，如果新建由于种种原因失败，重新创建的时候，很可能sysman用户没有删除，还存在一些role和public synonym. 最后通过select *from dba_synonyms where synonym_name like 'MGM%' 来查看关联的MGM相关的public synonym,发现竟然有差不多300多个 public synonym，这些public synonym是无法通过drop user sysman cascade来删除的，只能指定删除。 select 'DROP '||OWNER||' SYNONYM '||SYNONYM_NAME||';' from dba_synonyms where TABLE_owner='SYSMAN'; 发现是将近20个这样的public synonym 再次清理，就顺顺利利完成了EM的安装。
