SQL> create user hxl100 identified by oracle;
SQL> create user hxl200 identified by oracle;

2.sys使用者登入給新使用者授權

SQL> grant create session,resource to hxl100;

Grant succeeded.

SQL
 
> grant create session,resource to hxl200;

3.使用使用者hxl100登入建立表並寫入資料

SQL> connect hxl100/oracle

SQL> create table tb_100(id number,name varchar2(32));

Table created.

SQL> insert into tb_100 values(1,'name1');

1 row created.

SQL> insert into tb_100 values(2,'name2'
 
);

SQL> select * from tb_100;

        ID NAME
---------- --------------------------------
         1 name1

4.下面我們建立領域,讓hxl200使用者可以訪問hxl100下的表,但是sys和system不能訪問
