oracle分配权限：一个用户访问另一个用户的表

create synonym table1 for user1.table1;
这样当你在user2中查select * from table1时就相当于查select * from user1.table1;

//批量生成创建同义词
select ‘create synonym ‘||object_name||‘ for jys.‘||object_name||‘;‘ from dba_objects where owner=‘JYS‘ and object_type=‘TABLE‘;

不然就是在表前加用户名

select * from user1.table1
