Oracle建立表空间和用户
[sql] view
plain copy
建立表空间和用户的步骤:
用户
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;
[sql] view
plain copy
表空间
建立表空间(一般建N个存数据的表空间和一个索引空间):
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,
);
[sql] view
plain copy
例子:创建表空间
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
[sql] view
plain copy
用户权限
授予用户使用表空间的权限:
alter user 用户名 quota unlimited on 表空间;
或 alter user 用户名 quota *M on 表空间;
完整例子:
[sql] view
plain copy
--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 std;
--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;
[sql] view
plain copy
--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
