简单的职工信息管理系统（运用了存储过程，和datagridview，dataset的设置）

业界资讯 2022-06-13 04:26:21 阅读次数: 0

1、问题描述：

对职工信息进行管理，包括:职工信息的录入、显示、查询、修改、删除，要求有用户登录等windows窗口，用户数据存在数据库里。要求有用户登录等windows窗口，用户数据存在数据库里，并体现面向对象编程思想。

2、功能要求：

（1）录入职工信息并保存（职工信息包括职工号、姓名、性别、出生年月、学历、职务、工资、住址、电话等，并且要求职工号不重复；）

（2）显示所有职工信息

（3）查询职工信息（可按工号、按学历、按职务查询）

（4）修改职工信息并保存

（5）删除职工信息

（6）退出系统

值得一提的：

在c#中使用存储过程的写法

 SqlCommand sqlcmd = new SqlCommand();
            sqlcmd.CommandType = System.Data.CommandType.StoredProcedure;
            sqlcmd.Connection = conn;
            sqlcmd.CommandText = "xxxg";
            sqlcmd.Parameters.Add("@职工号", SqlDbType.VarChar, 10).Value = textBox2.Text;

在c#中使用Bindingsource已经dataset的用法，dataGridview的列名设置。

 bs = new BindingSource();
            SqlDataAdapter dr = new SqlDataAdapter(sql2, conn);
            DataSet myds = new DataSet();
            dr.Fill(myds);
            bs.DataSource = myds.Tables[0];//第一次写入默认为Tables[0]，第二次为Tables[1]
            this.dataGridView1.DataSource = bs;
            dataGridView1.Columns[0].HeaderCell.Value = "职工号";//列名设置
            dataGridView1.Columns[1].HeaderCell.Value = "名字";
            dataGridView1.Columns[2].HeaderCell.Value = "性别";

获取选择行的数据（要在datagridview中设置选中为一行的设置）

int hs = dataGridView1.CurrentRow.Index;//获取选中的行数；
textBox2.Text = dataGridView1.Rows[hs].Cells[0].Value.ToString();//将获得的数据写在文本框上

 

 存储过程的加入

写法

create proc name (
@职工号 varchar(10),
@姓名 varchar(10),
@性别 varchar(2),
@出生年月 varchar(20),
@学历 varchar(10),
@职务 varchar(15),
@工资 int,
@住址 varchar(10),
@电话 varchar(11)
)
as 
insert into 职工信息汇总表 (职工号,姓名,性别,出生年月,学历,职务,工资,住址,电话)
values (@职工号,@姓名,@性别,@出生年月,@学历,@职务,@工资,@住址,@电话)
//as后面是真正起作用的句子，但要在前面定义要用到的变量要记得加@。

 下面的菜单是给数据导航的

 基本的增删改查和按工号和学历已经按职务的模糊查询都可以

因为不太熟练，而且作为一个二年级混子，这种管理系统也花了我4个小时左右，嗯，我不应该在敲代码时老是去选BGM。
