变量名:NLS_LANG 变量值:SIMPLIFIED CHINESE_CHINA.ZHS16GBK
用户:create user 用户名 identified by "密码"; 受权: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;
创建表空间(通常建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 --自动增加 --还有一些定义大小的命令,看须要 default storage( initial 100K, next 100k, );
例子:建立表空间 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 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 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;
