answer_num number(3) not null,--回应数
click_num number(4) not null,--点击数
author_ip varchar2(16) ,--来源ip
lw_class1 varchar2(10) not null,--留言板大类 pk
lw_class2 varchar2(20) not null,--论坛栏目 pk
lw_type varchar2(1) not null,--留言类别,即是否为主贴
zt_time varchar2(14) ,--主贴时间
zt_author varchar2(40) ,--主贴email
lw_content varchar2(4000) ,--内容
constraint pk_guestbook primary key(lw_class1,lw_class2,lw
_time,lw_author)
) storage (initial 5M next 5M pctincrease 1);
