name varchar(32) not null,
password varchar(128) not null
);

create table empTable(
id int primary key auto_increment,
name varchar(64) not null,
grade tinyint,
email varchar(64) not null,
salary float
);
//添加初始化数据
insert into empAdminTable(id,name,password) values (100,'admin',md5('admin123'));

insert into empTable(name,grade,email,salary) values ('zhangsan',1,'zhangsan@163.com',250);

insert into empTable(name,grade,email,salary) values ('lisi01',1,'lisi01@sohu.com',250);
