Oracle方案操作

--wangwu用户
create table EMPP
(
  empno    NUMBER(4) not null,
  ename    VARCHAR2(10),
  job      VARCHAR2(9),
  mgr      NUMBER(4),
  hiredate DATE,
  sal      NUMBER(7,2),
  comm     NUMBER(7,2),
  deptno   NUMBER(2)
)
--这个select实际上是从当前方案中查找empp表
select * from wangwu.empp;
insert into empp (empno) values (123);

--system用户
--为chen用户添加对表的操作权限，否则会报表空间“USERS”无权限
ALTER USER "CHEN" QUOTA UNLIMITED ON "USERS";

--创建zhaoliu
create user zhaoliu identified by 123456;
grant create table,create session to ZHAOLIU;
select * from dba_sys_privs where grantee='ZHAOLIU'; 

--为zhaoliu添加对wangwu用户表empp的查询权限
grant select on wangwu.empp to zhaoliu;
select * from dba_sys_privs where grantee='WANGWU'; 
grant drop any table to zhaoliu;

--zhaoliu用户
select * from wangwu.empp;

drop table wangwu.empp;
