在上面的文件中添加新的数据库登录信息即可，例如：
192.168.0.6 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.6)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = hidydev)
    )

department varchar(20),
receiveTime datetime,
dealTime datetime,

对于MySQL，
create table opinion(
opinionId int  AUTO_INCREMENT 
);
Oracle不提供这种功能。
