Oracle建立表空间和用户方式

建立：create user 用户名 identified by "密码";
授权：grant create session to 用户名;
            grant create table to  用户名;
            grant create tablespace to  用户名;
            grant create view to  用户名;

create tablespace 表空间名
datafile ' 路径(要先建好路径)\***.dbf  ' size *M
tempfile ' 路径\***.dbf ' size *M
autoextend on  --自动增长
--还有一些定义大小的命令，看需要
 default storage(
 initial 100K,
 next 100k,
);

create tablespace DEMOSPACE 
datafile 'E:/oracle_tablespaces/DEMOSPACE_TBSPACE.dbf' 
size 1500M 
autoextend on next 5M maxsize 3000M;
删除表空间
drop tablespace DEMOSPACE including contents and datafiles

alter user 用户名 quota unlimited on 表空间;
或 alter user 用户名 quota *M on 表空间;

--表空间
CREATE TABLESPACE sdt
DATAFILE 'F:\tablespace\demo' size 800M
         EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO; 
--索引表空间
CREATE TABLESPACE sdt_Index
DATAFILE 'F:\tablespace\demo' size 512M         
         EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;     

--2.建用户
create user demo identified by demo 
default tablespace sdt;
 
--3.赋权
grant connect,resource to demo;
grant create any sequence to demo;
grant create any table to demo;
grant delete any table to demo;
grant insert any table to demo;
grant select any table to demo;
grant unlimited tablespace to demo;
grant execute any procedure to demo;
grant update any table to demo;
grant create any view to demo;

--导入导出命令   
ip导出方式： exp demo/demo@127.0.0.1:1521/orcl file=f:/f.dmp full=y
exp demo/demo@orcl file=f:/f.dmp full=y
imp demo/demo@orcl file=f:/f.dmp full=y ignore=y
