添加数据库类

创建数据库

//创建管理数据
create database mangerdata;

//创建用户表
create table user(
workid int primary key auto_increment,
name varchar(10) not null default '',
sex char(1) not null default '',
age tinyint unsigned not null default 0,
department varchar(10) not null default '',
job varchar(10) not null default '',
salary float not null default 0.0
);

配置数据库

导入数据库头文件

设置静态链接

将dll放入X64Debug中
