Oracle數據庫創建只讀用戶

創建一個只讀用戶user2，只能查詢管理員用戶user1下的表，不能增刪改。

操作環境：PL/SQL Developer

1、用管理員用戶user1登錄，創建用戶user2、並授權

--創建用戶user1，密碼123456
create user user2 identified by 123456;
--授權
grant connect to user2;
grant create synonym to user2;
grant create session to user2;

2、授予user2的查詢表權限：復制下面的查詢結果，執行

select 'grant select on '||owner||'.'||object_name||' to user2;'
 from dba_objects
 where owner in ('USER1')
 and object_type in ('VIEW','PROCEDURE','TABLE','FUNCTION');

3、為user2創建同義詞：復制下面的查詢結果，執行

select 'create or replace SYNONYM user2.' || object_name|| ' FOR ' || owner || '.' || object_name|| ';' 
from dba_objects
where owner in ('USER1')
and object_type in ('VIEW','PROCEDURE','TABLE','FUNCTION');

測試：
用user2登錄數據庫，查詢正常，增刪改提示沒有權限。
