数据访问接口的实现

数据库的generalUser表

    create table `estate_db`.`t_generaluser`(

        `UserID` int,

       `UserName` varchar(20) default '' not null,

       `UserPwd` varchar(20) default '' not null,

       `UserEmail` varchar(40) unique,

       `PwdQuestion` varchar(40) default '' not null,

       `PwdAnswer` varchar(20) default '' not null,

       `FormRoleID` int,

       `PlatRoleID` int,

       `Tel` varchar(20) default '' not null,

       `qq` varchar(20),

       `RegTime` datetime,

       `EditTime` datetime,

       `LoginTimes` int,

       `LastLoginTime` datetime,

       `LockFlag` bit,

       `CompanyName` varchar(40),

        primary key (`UserName`)

    );

    create unique index `PRIMARY` on `estate_db`.`t_generaluser`(`UserName`);

    create unique index `UserName_UNIQUE` on `estate_db`.`t_generaluser`(`UserName`);

    create unique index `UserEmail_UNIQUE` on `estate_db`.`t_generaluser`(`UserEmail`);

数据库的t_admin表:

    create table `estate_db`.`t_admin`(

        `AdminID` int,

       `AdminName` varchar(20) not null,

       `AdminPwd` varchar(20),

       `RegTime` datetime,

        primary key (`AdminName`)

    );

    create unique index `PRIMARY` on `estate_db`.`t_admin`(`AdminName`);

    create unique index `AdminName_UNIQUE` on `estate_db`.`t_admin`(`AdminName`);

数据库连接工具:ConnectioUtil

generalUser用户：类generalUser

generalUser注册程序的SQL语句：insert t_generalUser(UserName,UserPwd,userEmail,PwdQuestion,PwdAnswer)

values('FenYun','3698741','FenYun@163.com','我喜爱的动物','白鸽');

generalUser登录程序的SQL语句:

select * from t_generalUser where UserName like 'FenYun' and UserPwd like '3698741';

统计当前用户数量的SQL语句:

select  count(*) from t_generalUser;

admin用户:类admin

admin登录程序的SQL 语句:

select * from t_admin where AdminName LIKE 'yantai' AND AdminPwd like 'yantai';
