Oracle建立表空间和用户                 

 

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 *Mtempfile ' 路径\***.dbf ' size *Mautoextend 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 sdtDATAFILE 'F:\tablespace\demo' size 800M         EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO; --索引表空间CREATE TABLESPACE sdt_IndexDATAFILE '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;
