Oracle建立表空间和用户
Oracle建立表空间和用户
完整样例:
建立表空间和用户的步骤: 用户 建立:create user username identified by "password"; 授权:grant create session to username; grant create table to username; grant create tablespace to username; grant create view to username;
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 --自己主动增长 --另一些定义大小的命令,看须要 default storage( initial 100K, next 100k, );
样例: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
用户权限 授予用户使用表空间的权限: alter user username quota unlimited on 表空间; 或 alter user username quota *M on 表空间;
完整样例:
--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 demo; --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;
