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(只建文件夹不创建文件)\***.dbf ' size 800M
);
[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
07.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 ly;
grant create any sequence to ly;
grant create any table to ly;
grant delete any table to ly;
grant insert any table to ly;
grant select any table to ly;
grant unlimited tablespace to ly;
grant execute any procedure to ly;
grant update any table to ly;
grant create any view to ly;
