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

Sql代码

--账户解锁

alter user scott account unlock;

--重设scott账户口令为tiger

alter user scott identified by tiger;

附:实例表建表语句(适用于Oracle)
