Oracle创建Schema、用户名及表空间

1 创建新用户

create user usename identified by password;

SQL> create user zxy identified by yyds;

2 查看当前表空间

SQL> select tablespace_name from user_tablespaces;

TABLESPACE_NAME

UNDOTBS1
TEMP
USERS

3 创建表空间

create tablespace spacename datafile 'filedir';

spacename : 是自定义的表空间名字，当然也是新的Schema的名称

filedir : 文件存储路径，可随意选择一个磁盘空间充足的目录

SQL> create tablespace zxy datafile '/home/oracle/app/oracle/oradata/helowin/zxy.dbf' size 100m;

Tablespace created.

4 将空间分配给用户

alter user username default tablespace spacename;

SQL> alter user zxy default tablespace zxy;

User altered.

5 给用户授权

grant create session,create table,unlimited tablespace to username;

SQL> grant create session,create table,unlimited tablespace to zxy;

Grant succeeded.

6 查看表空间

SQL> select tablespace_name from user_tablespaces;

TABLESPACE_NAME

7 连接
