以前开发的时候用得比较多的是mysql和sql server,Oracle用的比较少,用起来比较生疏,mysql和sql server用起来比较类似,,就Oracle的使用方式和他们不同,Oracle在创建数据库的时候要对应一个用户,数据库和用户一般一一对应,mysql和sql server 直接通过create databse “数据库名” 就可以直接创建数据库了,而Oracle创建一个数据库需要以下三个步骤:

1.创建两个数据库的文件

2.创建用户与上面创建的文件形成映射关系

3.给用户添加权限

一、创建两个数据库的文件(monitor.dbf 和monitor_temp.dbf 两个文件)

CREATE TABLESPACE monitor LOGGING DATAFILE 'E:\app\owner\oradata\orcl\monitor.dbf'

SIZE 100M AUTOEXTEND ON NEXT 32M MAXSIZE 500M EXTENT MANAGEMENT LOCAL;

create temporary tablespace monitor_temp tempfile 'E:\app\owner\oradata\orcl\monitor_temp.dbf'

size 100m autoextend on next 32m maxsize 500m extent management local;

二、创建用户与上面创建的文件形成映射关系(用户名为monitor,密码为monitor)

CREATE USER monitor IDENTIFIED BY monitor DEFAULT TABLESPACE monitor TEMPORARY TABLESPACE monitor_temp;

三、添加权限

grant connect,resource,dba to monitor;

grant create session to monitor;

  有时候也会用到删除数据库和删除用户的操作,这里也给出删除的语句

四、删除数据库

DROP TABLESPACE monitor INCLUDING CONTENTS AND DATAFILES;

五、删除用户

drop user monitor cascade;

亲身试验可用。
