请教一个java数据访问问题(最后50分相送)

Question

你赶紧把asp和.net忘了再来学java 
要不然
你肯定学不会

Answer 1

和ASP,.NET不一样.
数据访问这块,随便找点资料都提到了

Answer 2

这几天看了些j2ee感觉好多方面和.net都差不多, 比如RowSet, PooledConnection
我觉得如果参考.net去看可能会更有效果.

Answer 3

public void add(Registration r1) {
        String sql =
                "insert into registration (RID,USERNAME,PASSWORD,PASSWORDHINT,PASSWORDSOLUTION,SEX,EMAIL,NICKNAME,BIRTHDAY,QQ,TELEPHONE,ADDRESS,HOMEPAGE,HEAD,SELVES,LID) "
                + " values (registration_seq.NEXTVAL, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
        Connection conn = null;
        try {
            conn = DBTools.getConn();
            PreparedStatement ps = conn.prepareStatement(sql);
            ps.setString(1, r1.getUserName());
            ps.setString(2, r1.getPassword());
            ps.setString(3, r1.getPasswordHint());
            ps.setString(4, r1.getPasswordSolution());
            ps.setString(5, r1.getSex());
            ps.setString(6, r1.getEmail());
            ps.setString(7, r1.getNickName());
            ps.setTimestamp(8, new Timestamp(r1.getBirthday().getTime()));
            ps.setInt(9, r1.getQq());
            ps.setInt(10, r1.getTelephone());
            ps.setString(11, r1.getAddress());
            ps.setString(12, r1.getHomepage());
            ps.setString(13, r1.getHead());
            ps.setString(14, r1.getSelves());
            ps.setInt(15, r1.getLid());
            System.out.println(sql);
            ps.executeUpdate();
        } catch (Exception ex) {
            ex.printStackTrace();
        } finally {
            DBTools.close(conn);
        }给你一个简单的示例  JAVA里也有ResultSet  不过之间的区别或用法 自己还是看书吧..
