oracle使用初体验
大概10天前在网上下载了个oracle 10g，当时不知道oracle10g没有图形界面了，所以开始怎么建表，在哪建表都一头雾水。8i,9i都有图形界面工具 DBA STUDIO的。10g 的client也提供这个,需要另外装的。10g已经用website 方式了。
另外，如果安装过程中全部选择默认的（没有自己配置一些高级选项），有人完成之后不知道用户名和密码，其实oracle自带了默认用户名和密码。

我用的是SYSTEM/MANAGER进入的。
在Oracle Enterprise Manager中有个用户－>创建用户就可以创建自己的用户名和密码。
要创建表的话，先用SYSTEM/MANAGER进入ORACLE SQL*Plus，然后创建用户：
（1）create useruserName identified bypwd;(userName是你的用户名，pwd是你的密码，下同)。
然后给你的用户授予权限：
（2）grant connect,resource to userName;
第三步是连接到你的用户：
（3）conn userName/pwd;
第四步创建表：
（4）create table test(a number,name varchar(20));
另外了解到有个Oracle 的第三方辅助工具（图形界面的）：pl/sql developer，感觉还不错。
搞了3－4个小时，终于对Oracle 10g建表的过程有所了解了，至少可以应用在简单的开发当中了，呵呵。
