用Java如何连接SQL SERVRE(最好有源代码)

Question

1.先找个第四种驱动装上；当然走ODBC就不用说了；
2，了解那几个对象就OK了；

Answer 3

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
con = DriverManager.getConnection("jdbc:microsoft:sqlserver://servername:1433","userid","password");

Answer 4

private static String dbDriver;//数据库驱动
  private static String dbURL;//数据库路径
  private Connection conn;//建立数据库连接对象
  public static ResultSet rs;//结果集对象
 conn = DriverManager.getConnection(dbURL,"jsp_user","jsp");
                Statement stmt = conn.createStatement();
                sql = "insert into leader (id,leader_name,leader_level,leader_position,leader_intro,department,working,tel,photo)  values("+id+",'"+leader_name+"','"+leader_level+"','"+leader_position+"','"+leader_intro+"','"+department+"','"+working+"','"+tel+"','"+photo+"')";
                success = stmt.executeUpdate(sql);
stmt.close();
                conn.close();
