物资管理系统

本实例采用datagridview绑定Oracle数据源来显示相关的数据信息。物资管理系统实现了4大管理和3大查询功能，分别是入库管理、领用管理、归还管理、人员管理、领用查询、资产查询、人员查询，1.0版只是大概实现了简单的功能，程序还有待改进。由于数据库装在了另外一台服务器上，所以就不对数据库表结构进行说明了，下面讲一下所用到的sql语句。

  • 入库管理

 6                 conn.Open();
 7                 OracleCommand cmd = new OracleCommand();
 8                 cmd.Connection = conn;
 9                 
10                 cmd.CommandText = "insert into 表名(DATA,CODE,NAME,QUANTITY,PRICE,ACCOUNTING,OWENER,CHECKING,TOUCHING,REMARKS) values(sysdate,'" + textBox3.Text + "','" + textBox6.Text + "','" + textBox8.Text + "','" + textBox9.Text + "','" + textBox2.Text + "','" + comboBox2.Text + "','" + comboBox1.Text + "','" + textBox7.Text + "','" + textBox10.Text + "')";
11                 cmd.CommandType = CommandType.Text;
12                 cmd.ExecuteNonQuery();
13                 conn.Close();
14 
15             }
16             catch(OracleException ex)
17             {
18                 MessageBox.Show("数据库连接异常，请检查网络连接！");

20             finally
21             {
22                 this.Close();
