oracle的练习表---employee

转载于：http://lj6684.iteye.com/blog/771681

 

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tiger
alter user scott identified by tiger;

 适用于Oracle的SQL：

emp在建立的时候，报无效的月份，为什么 ？
