ORACLE建表语句如下(自动编号栏位+外键定义)：
/*
--drop index SCOTT.utweb_user_funcs_map_IDX1;
drop SEQUENCE scott.utweb_user_funcs_map_autoid;
drop table scott.utweb_user_functions_mapping;
--drop index SCOTT.utweb_functions_IDX1;
drop table scott.utweb_functions;
--drop index SCOTT.utweb_users_IDX1;
drop table scott.utweb_users;
--drop index SCOTT.utweb_visitorlog_IDX1;
drop SEQUENCE scott.utweb_visitorlog_autoid;
drop table scott.utweb_visitorlog;
--drop index SCOTT.utweb_orderconfirmmail_IDX1;
drop SEQUENCE scott.utweb_orderconfirmmail_autoid;
drop table scott.utweb_orderconfirmmail;
*/
