sqlserver2000数据库访问

 

 增加数据：

    Connection con = null;

    Statement stmt = null;

    int row = 0;

    //获取GUI信息

    String stuID = stuIDTextField.getText();

    String stuName = stuNameTextField.getText();

    String stuDepart = (String) departComboBox.getSelectedItem();

    String stuClass = (String) classComboBox.getSelectedItem();

    //检测

    if (stuID.equals("") || stuName.equals("")) {

        JOptionPane.showMessageDialog(this,"请填写完整");

        return;

    } else {

 

    try {

   //注册直连驱动   

 Class.forName("com.microsoft.jdbc.sqlserver.sqlServerDriver");

   //建立连接

   String url="jdbc:microsoft:sqlserver://localhost:1433;databasename=JDBC_STU";

 con = DriverManager.getConnection(url,"sa","sql2008");

  //创建执行语句,拼接字符串

   String insertsql = "insert into studentinfo values('" + stuID + "','" + stuName + "','" + stuDepart + "','" + stuClass + "')";

   stmt = con.createStatement();

 

注意：驱动的加载和jar包的导入

        //发送sql语句

            row = stmt.executeUpdate(insertsql);

            if (row != 0) {

                JOptionPane.showMessageDialog(this,"添加成功");

                stuIDTextField.setText("");

                stuNameTextField.setText("");

            } catch(sqlException ex){

            JOptionPane.showMessageDialog(this,"添加失败");

            stuIDTextField.setText("");

            stuNameTextField.setText("");   

        } catch (Exception ex) {

            ex.printstacktrace();

        } finally {

            try {

                con.close();//关闭连接

 

            } catch (Exception ex) {

                ex.printstacktrace();

            }

        }

}
