 4     Private    final    static    String    driver    =    "com.microsoft.sqlserver.jdbc.SQLServerDriver";
 5      // 02.定义连接字符串
 6     private final static String url = "jdbc:sqlserver://192.168.8.50:1433;DatabaseName=Myschool";
 7     //03.用户名
 8     private final static String username = "sa";
 9    //04.密码
10     private final static String pwd = "";
11    //05.创建连接
12 Connection    con=DriverManager.getConnection(url, user, password);
13   //05.执行操作
14         PreparedStatement st=null;
15         String sql="insert into grade(gradename) values(?)";
16         try {
17             st=con.prepareStatement(sql);
18         } catch (SQLException e) {
19             e.printStackTrace();
20         }
21         
22         try {
23             st.setString(1, gradename);
24         } catch (SQLException e1) {
25             // TODO Auto-generated catch block
26             e1.printStackTrace();
27         }
