关于Oracle数据库中的employee范例表

关于Oracle数据库中的employee实例表
Oracle数据库安装的时候会自带一个练习用数据库（其中包含employee表，后来版本中此表改名为emp）；

首先在安装过程中应该有个选项“是否安装实例表”（完全安装模式下默认是选择的），需要选择才有此表；

此表归属于scott账户，scott用户默认口令为tiger
如果发现scott账户已过期（Oracle 10g中经常发生），或口令不正确，可以通过以下方法进行设置

--账户解锁alter user scott account unlock;--重设scott账户口令为tigeralter user scott identified by tiger;
