1、創建用戶並賦予權限(sqlplus / as sysdba)
創建用戶
create user Scaffold identified by Scaffold;
創建一個表空間
create tablespace Scaffold datafile '/app/oracle/oradata/OFSAA/Scaffold.dbf' size 1000M;
表空間分配給用戶
alter user Scaffold default tablespace Scaffold;
sql語句來查看一下所有用戶所在的表空間
select username,default_tablespace from dba_users;
用戶分配權限
grant create session,create table,create view,create sequence,unlimited tablespace to Scaffold;
2、創建表語句及對錶操作
--創建表
create table classes(
id number(9) not null primary key,
classname varchar2(40) not null
)
--查詢表
select * from tablename;
--刪除表
drop table students;
--修改表的名稱
rename alist_table_copy to alist_table;
--插入數據
insert into tablename values(class_seq.nextval,'軟件一班')
